Description

Technical Field

[0001] The present disclosure relates to the field of cloud computing technology, specifically the field of cloud mobile phone technology, and can be applied to cloud gaming scenarios. Background Art

[0002] Cloud gaming is a gaming method based on cloud computing. In this mode, all games are run on the server, and the rendered game images are compressed and transmitted to the client over the network. The client does not require any high-end processors or graphics cards, only basic video decompression capabilities.

[0003] However, there are a wide variety of client brands and decoding chips, and each client has different hardware decoding capabilities. To ensure optimal compatibility and user experience, multiple video formats must be used for streaming. For example, in current cloud phone services, the increasingly popular H265 video format can be pushed through a server-side whitelist configuration. Only clients on the whitelist will use the H265 video format for streaming. All other clients will use the H264 video format by default. Summary of the Invention

[0004] The embodiments of the present disclosure provide a method, apparatus, device, storage medium, and program product for video decoding on a cloud phone.

[0005] In a first aspect, an embodiment of the present disclosure proposes a video decoding method for a cloud phone, comprising: in response to a client starting the cloud phone, detecting whether the client has a decoder for decoding videos of a first video compression standard; in response to the decoder having the ability to decode videos of the first video compression standard, decoding the pushed video of the cloud phone based on at least one resolution supported by the first video compression standard; in response to successful decoding of the pushed video based on at least one resolution, playing the video obtained by decoding the pushed video based on the first video compression standard.

[0006] In the second aspect, an embodiment of the present disclosure proposes a video decoding device for a cloud phone, including: a detection module, configured to detect whether the client has a decoder for decoding videos of a first video compression standard in response to the client starting the cloud phone; a decoding module, configured to decode the pushed streaming video of the cloud phone based on at least one resolution supported by the first video compression standard in response to the decoder having the ability to decode videos of the first video compression standard; a first playback module, configured to play the video obtained by decoding the pushed streaming video based on the first video compression standard in response to successful decoding of the pushed streaming video based on at least one resolution.

[0007] In a third aspect, an embodiment of the present disclosure proposes an electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to execute the method described in the first aspect.

[0008] In a fourth aspect, an embodiment of the present disclosure proposes a non-transitory computer-readable storage medium storing computer instructions, where the computer instructions are used to enable a computer to execute the method described in the first aspect.

[0009] In a fifth aspect, an embodiment of the present disclosure proposes a computer program product, including a computer program, which implements the method described in the first aspect when executed by a processor.

[0010] The disclosed embodiment provides a video decoding method for a cloud phone. The SDK actively initiates decoding detection of the streaming video of the cloud phone, and combines the properties of the client's hardware decoder to intelligently decide the most appropriate video decoding format and resolution. There is no need to rely on the whitelist configuration on the server side or to cooperate with other departments, which simplifies the operation process. Through this pre-detection method, it can be ensured that the current client can use the optimal video format and resolution to initiate video streaming, thereby improving the quality and smoothness of the streaming video. It not only simplifies the processing flow of video streaming, but also improves the success rate of video streaming, providing users with a better video experience.

[0019] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Figure 1 An exemplary system architecture 100 is shown in which the present application may be applied.

[0022] like Figure 1 As shown, system architecture 100 may include terminal device 101, network 102, and server 103. Network 102 is used to provide a medium for a communication link between terminal device 101 and server 103. Network 102 may include various connection types, such as wired or wireless communication links or fiber optic cables.

[0023] The user can use the terminal device 101 to interact with the server 103 through the network 102 to receive or send messages, etc. Various client applications can be installed on the terminal device 101, such as a cloud gaming application.

[0024] The terminal device 101 can be hardware or software. When the terminal device 101 is hardware, it can be various electronic devices, including but not limited to smartphones, tablet computers, laptop computers, and desktop computers. When the terminal device 101 is software, it can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules (for example, multiple software or software modules for providing distributed services), or it can be implemented as a single software or software module. No specific limitations are given here.

[0025] Server 103 can be a server that provides various services, such as a backend server for a cloud gaming application. Cloud gaming can run on server 103 and compress the rendered game screen before transmitting it to terminal device 101 via network 102. Terminal device 101 decompresses the compressed game screen to display it.

[0026] It should be noted that the server 103 can be hardware or software. When the server 103 is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server 103 is software, it can be implemented as multiple software or software modules (for example, for providing distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0027] It should be noted that the video decoding method of the cloud phone provided in the embodiment of the present application is generally executed by the terminal device 101. Accordingly, the video decoding device of the cloud phone is generally set in the terminal device 101.

[0028] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0029] Continue to refer Figure 2 , which shows a process 200 of an embodiment of a video decoding method of a cloud phone according to the present disclosure. The video decoding method of the cloud phone includes the following steps:

[0030] Step 201 , in response to the client starting the cloud phone, detecting whether the client has a decoder for decoding videos of a first video compression standard.

[0031] In this embodiment, when the client starts the cloud phone, it can detect whether the client has a decoder capable of decoding videos of the first video compression standard. If the client has a decoder capable of decoding videos of the first video compression standard, step 202 is continued.

[0032] Typically, the server can provide the client with an SDK (Software Development Kit) for streaming of the cloud phone. The client can install the SDK to integrate the cloud phone into the client. When the client starts the cloud phone, the SDK will be run and loaded. At this time, it can be detected whether the client has a decoder for decoding videos of the first video compression standard. Specifically, the client's configuration information can be obtained to determine whether it has a decoder for decoding videos of the first video compression standard.

[0033] A cloud phone is a mobile phone that applies cloud computing technology to network terminal services, accessing cloud services through cloud servers. Based on integrated end-to-end virtualization technology, cloud phones leverage digital capabilities such as cloud networking, security, and artificial intelligence to flexibly adapt to users' personalized needs, freeing up the phone's hardware resources to load a vast array of cloud applications on demand. Because cloud phones run on 5G networks, they can store complex calculations and large amounts of data in the cloud. Users can remotely control cloud phones in real time via video streaming, ultimately enabling the cloud-based operation of native Android apps and mobile games.

[0034] The first video compression standard may be, for example, a newly developed video compression standard that can provide higher video quality and lower bandwidth requirements, thereby enhancing the user's viewing experience and bringing better services to users. For example, in the current cloud phone service, the first video compression standard may be, for example, H265. Among them, H265 is also known as HEVC (High Efficiency Video Coding), which is one of the several potential successors to the widely used AVC (Advanced Video Coding). Compared with AVC, H265 provides approximately twice the data compression ratio at the same video quality level, or significantly improves video quality at the same bit rate. H265 supports multiple resolutions, among which the mainstream resolutions are 1080*1920 and 720*1280.

[0035] Step 202 : In response to a decoder capable of decoding videos in accordance with a first video compression standard, the streaming video of the cloud phone is decoded based on at least one resolution supported by the first video compression standard.

[0036] In this embodiment, if the client has a decoder for decoding videos of the first video compression standard, the streaming video of the cloud phone can be decoded based on at least one resolution supported by the first video compression standard.

[0037] Among them, the first video compression standard can support at least one resolution. Here, the pushed streaming video of the cloud phone can be decoded based on at least one resolution supported by the first video compression standard. For example, the first video compression standard supports two mainstream resolutions, and the pushed streaming video of the cloud phone can be decoded based on these two mainstream resolutions respectively. In some embodiments, the pushed streaming video of the cloud phone is first decoded based on the largest mainstream resolution. If the decoding is successful, the corresponding decoded video is obtained; if the decoding fails, the pushed streaming video of the cloud phone is decoded using the smallest mainstream resolution. If the decoding is successful, the corresponding decoded video is obtained. In some embodiments, the pushed streaming video of the cloud phone is decoded based on two mainstream resolutions at the same time. If only one mainstream resolution is decoded successfully, the decoded video corresponding to the successfully decoded resolution is obtained; if both mainstream resolutions are decoded successfully, the decoded video corresponding to the largest resolution is obtained. It can be seen that the above two embodiments can ensure that the client can use the optimal video format and resolution to initiate video streaming, thereby improving the quality and smoothness of the pushed streaming video.

[0038] Step 203 : In response to the successful decoding of the pushed stream video based on at least one resolution, a video obtained by decoding the pushed stream video based on the first video compression standard is played.

[0039] In this embodiment, if the push-stream video is successfully decoded based on at least one resolution, the video obtained by decoding the push-stream video based on the first video compression standard can be played. For example, if the push-stream video of the cloud phone is successfully decoded based on the maximum mainstream resolution, the video obtained by decoding the push-stream video of the cloud phone based on the maximum mainstream resolution can be played. If the push-stream video of the cloud phone fails to be decoded based on the maximum mainstream resolution, but the push-stream video of the cloud phone is successfully decoded based on the minimum mainstream resolution, the video obtained by decoding the push-stream video of the cloud phone based on the minimum mainstream resolution can be played.

[0040] The disclosed embodiment provides a video decoding method for a cloud phone. The SDK actively initiates decoding detection of the streaming video of the cloud phone, and combines the properties of the client's hardware decoder to intelligently decide the most appropriate video decoding format and resolution. There is no need to rely on the whitelist configuration on the server side or to cooperate with other departments, which simplifies the operation process. Through this pre-detection method, it can be ensured that the current client can use the optimal video format and resolution to initiate video streaming, thereby improving the quality and smoothness of the streaming video. It not only simplifies the processing flow of video streaming, but also improves the success rate of video streaming, providing users with a better video experience.

[0041] Further references Figure 3, which shows a process 300 of an embodiment of a video decoding method of a cloud phone according to the present disclosure. The video decoding method of the cloud phone includes the following steps:

[0042] Step 301: The client starts the cloud phone.

[0043] In this embodiment, the client can start the cloud phone.

[0044] Typically, the server provides the client with a cloud phone SDK for streaming. The client can install the SDK to integrate the cloud phone into the client. When the client launches the cloud phone, the SDK is run and loaded.

[0045] A cloud phone is a mobile phone that applies cloud computing technology to network terminal services, accessing cloud services through cloud servers. Based on integrated end-to-end virtualization technology, cloud phones leverage digital capabilities such as cloud networking, security, and artificial intelligence to flexibly adapt to users' personalized needs, freeing up the phone's hardware resources to load a vast array of cloud applications on demand. Because cloud phones run on 5G networks, they can store complex calculations and large amounts of data in the cloud. Users can remotely control cloud phones in real time via video streaming, ultimately enabling the cloud-based operation of native Android apps and mobile games.

[0046] Step 302: Detect whether the client has a decoder capable of decoding videos of the first video compression standard.

[0047] In this embodiment, when the client starts the cloud phone, it can detect whether the client has a decoder capable of decoding videos in the first video compression standard. If the client has a decoder capable of decoding videos in the first video compression standard, step 303 is executed; if the client does not have a decoder capable of decoding videos in the first video compression standard, step 310 is continued.

[0048] When the client starts the cloud phone, the SDK will be run and loaded. At this time, it can be detected whether the client has a decoder for decoding videos in the first video compression standard. Specifically, the client's configuration information can be obtained to determine whether it has a decoder for decoding videos in the first video compression standard.

[0049] The first video compression standard may be, for example, a newly developed video compression standard that can provide higher video quality and lower bandwidth requirements, thereby enhancing the user's viewing experience and bringing better services to users. For example, in the current cloud phone service, the first video compression standard may be, for example, H265. Among them, H265, also known as HEVC, is one of several potential successors to the widely used AVC. Compared with AVC, H265 provides approximately twice the data compression ratio at the same video quality level, or significantly improves video quality at the same bit rate. H265 supports multiple resolutions, among which the mainstream resolutions are 1080*1920 and 720*1280.

[0050] Step 303: Decode the pushed stream video using at least one resolution in descending order of resolution until the pushed stream video is successfully decoded.

[0051] In this embodiment, if the client has a decoder for decoding videos of the first video compression standard, the pushed video can be decoded using at least one resolution in descending order of resolution until the pushed video is successfully decoded.

[0052] The first video compression standard may support at least one resolution. For example, if the first video compression standard supports two mainstream resolutions, the cloud phone's pushed video can be decoded based on these two mainstream resolutions. Specifically, the cloud phone's pushed video is first decoded based on the largest mainstream resolution. If decoding is successful, decoding stops. If decoding fails, the cloud phone's pushed video is decoded using the smallest mainstream resolution.

[0053] Step 304: Determine whether the pushed video is successfully decoded using the maximum resolution among the at least one resolution.

[0054] In this embodiment, it is determined whether the pushed stream video is successfully decoded using the maximum resolution among the at least one resolution. If the pushed stream video is successfully decoded using the maximum resolution among the at least one resolution, step 305 is executed; if the pushed stream video is not successfully decoded using the maximum resolution among the at least one resolution, step 309 is executed.

[0055] Step 305: Determine the maximum resolution of the first video compression standard supported by the decoder.

[0056] In this embodiment, if the pushed video is successfully decoded using the maximum resolution among at least one resolution, the maximum resolution of the first video compression standard supported by the decoder can be determined. Specifically, the client configuration information can be obtained to determine the maximum resolution of the first video compression standard supported by the decoder. The maximum resolution of the first video compression standard supported by the decoder is related to the client configuration, and the maximum resolution of the first video compression standard supported by the decoders of different clients generally varies.

[0057] Step 306: Determine whether the maximum resolution of the first video compression standard supported by the decoder is greater than the maximum resolution of the at least one resolution.

[0058] In this embodiment, it is determined whether the maximum resolution of the first video compression standard supported by the decoder is greater than the maximum resolution of the at least one resolution. If the maximum resolution of the first video compression standard supported by the decoder is greater than the maximum resolution of the at least one resolution, step 307 is executed; if the maximum resolution of the first video compression standard supported by the decoder is not greater than the maximum resolution of the at least one resolution, step 308 is executed.

[0059] Step 307 : Play the video obtained by decoding the pushed stream video using the maximum resolution of the first video compression standard supported by the decoder.

[0060] In this embodiment, if the maximum resolution of the first video compression standard supported by the decoder is greater than the maximum resolution of at least one resolution, the video obtained by decoding the pushed video using the maximum resolution of the first video compression standard supported by the decoder can be played.

[0061] Step 308: Play a video obtained by decoding the pushed stream video using the maximum resolution among the at least one resolution.

[0062] In this embodiment, if the maximum resolution of the first video compression standard supported by the decoder is not greater than the maximum resolution of at least one resolution, a video obtained by decoding the pushed video using the maximum resolution of at least one resolution can be played.

[0063] Step 309 : Play the video obtained by decoding the pushed stream video using the resolution at which decoding is successful.

[0064] In this embodiment, if the pushed stream video is successfully decoded using at least one resolution other than the maximum resolution, a video obtained by decoding the pushed stream video using the successfully decoded resolution may be played.

[0065] Step 310: Determine the maximum resolution of the second video compression standard supported by the decoder.

[0066] In this embodiment, if decoding of the pushed video fails based on at least one resolution, the maximum resolution of the second video compression standard supported by the decoder can be determined. Specifically, the client configuration information can be obtained to determine the maximum resolution of the second video compression standard supported by the decoder. The maximum resolution of the second video compression standard supported by the decoder is related to the client configuration, and the maximum resolution of the second video compression standard supported by the decoders of different clients generally varies.

[0067] The second video compression standard can be, for example, a commonly used video compression standard. Typically, the second video compression standard supports a lower resolution than the first video compression standard. For example, in current cloud phone services, the first video compression standard can be H265, and the second video compression standard can be H264. H264 is a highly compressed digital video codec standard. H264's greatest advantage is its high data compression ratio. The low bit rate plays a significant role in H264's high compression ratio. H264 compression technology will significantly save users download time and data usage charges. It is particularly noteworthy that H264 not only achieves a high compression ratio but also produces high-quality and smooth images. Because of this, video data compressed by H264 requires less bandwidth during network transmission, making it more economical. H265 is a new video coding standard developed after H264. Compared to H264, it can provide higher video quality and lower bandwidth requirements.

[0068] Step 311 : Play a video obtained by decoding the pushed stream video using the maximum resolution of the second video compression standard supported by the decoder.

[0069] In this embodiment, after determining the maximum resolution of the second video compression standard supported by the decoder, the pushed video can be decoded using the maximum resolution of the second video compression standard supported by the decoder and the decoded video can be played. This ensures that even if decoding of the first video compression standard fails, the second video compression standard can still be used for pushing the video.

[0070] The disclosed embodiments provide a cloud phone video decoding method that can automatically detect and identify the decoding status of cloud phone videos supported by a client, and has the following significant advantages:

[0071] 1. Efficient Decision-Making: The SDK proactively detects the actual video decoding of the cloud phone's live streams and, based on the client's hardware decoder properties, intelligently determines the most appropriate video decoding format and resolution. This mechanism ensures that the H.265 video format is prioritized for high-quality, low-data-rate streaming, providing users with a superior viewing experience.

[0072] 2. Simplified process: No need to rely on server-side whitelist configuration or coordination with other departments, simplifying the operation process. This greatly accelerates the promotion of H265 video streaming.

[0073] 3. Improved success rate: By increasing detection of H265 and H264 and determining resolution, the probability of successful streaming connection on cloud phones has been increased. This improvement ensures the stability and reliability of streaming connections and reduces connection interruptions or failures.

[0074] In summary, automatic detection and intelligent decision-making simplify the operational process and improve the quality and success rate of video streaming. This provides users with a smoother, higher-quality cloud mobile video experience and a more efficient video streaming solution for service providers.

[0075] Further references Figure 4 , which shows a process 400 of a scenario in which the video decoding method of the cloud phone of the present disclosure can be implemented, including the following steps:

[0076] Step 401: Determine whether the mobile phone decoder supports H265. If so, execute steps 402 and 403; if not, execute step 409.

[0077] Step 402: Obtain the maximum width and height supported by the mobile phone H265 decoder.

[0078] Step 403: Check if the 1080*1920 H265 video is successfully decoded. If so, go to step 404; if not, go to step 407.

[0079] Step 404: Determine whether the maximum width and height are greater than 1080*1920. If so, proceed to step 405; if not, proceed to step 406.

[0080] Step 405: Obtain the maximum width and height supported by the mobile phone H265 decoder.

[0081] In step 406, the maximum value supported by the H265 decoder is 1080*1920.

[0082] Step 407: Check whether the 720*1280 H265 video is successfully decoded. If so, go to step 408; if not, go to step 409.

[0083] In step 408, the maximum value supported by the H265 decoder is 720*1280.

[0084] Step 409: H265 is not supported.

[0085] Step 410: Obtain the maximum width and height supported by the mobile phone H264 decoder.

[0086] In the scenario of implementing the video decoding method of the cloud phone disclosed in the present invention, when the SDK is loaded, a mechanism is designed to detect whether the mobile phone client has a hardware decoder for decoding H265 videos. If supported, hardware decoding attempts are made on the cloud phone streaming video in the H265 encoding format with two pre-built-in resolutions. By judging whether a complete video frame can be decoded, it can be determined whether the current mobile phone client has the ability to decode H265 videos. Once the decoding is successful, the maximum resolution supported by the client's current decoder for decoding H265 is also parsed so that the appropriate resolution can be selected during subsequent streaming.

[0087] If H265 decoding fails, the maximum resolution supported by the client's current decoder for H264 decoding will be analyzed. This step ensures that H264 can still be used for streaming even if H265 decoding fails.

[0088] This pre-detection method ensures that the current client can initiate video streaming using the optimal video format and resolution, thereby improving the quality and smoothness of the streaming. This design not only simplifies the video streaming process, but also increases the success rate of video streaming, providing users with a better video experience.
