Detailed implementation manners

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] To facilitate the understanding of this embodiment, the technical terms designed in this application will be briefly introduced below.

[0023] Frame rate (Frames Per Second, FPS) refers to the number of image frames displayed per second. Common frame rates include 24fps (movies), 25fps (PAL television standard), 30fps (NTSC television standard), 60fps, etc. The higher the frame rate, the better the video smoothness, but the file size will also increase.

[0024] The decoding playback multiple refers to the playback speed dynamically adjusted according to the decoding and caching conditions during video playback.

[0025] After introducing the technical terms involved in this application, next, the application scenarios and design concepts of the embodiments of this application will be briefly introduced.

[0026] Existing Web players face a dilemma when playing media streams: setting a large cache for smoothness will result in high live broadcast latency, and reducing the cache for real-time performance may cause the picture to freeze when the network is poor, both of which affect the viewing experience.

[0027] Based on this, the embodiments of this application provide a media stream real-time playback method, device, electronic device, and storage medium.

[0028] Embodiment 1 This application provides a method for real-time media stream playback, which combines Figure 1 As shown, the method includes: S110, obtaining the target frame rate of the video source and the frame rate of the player's decoded frames.

[0029] S120, adjusting the input buffer threshold of the decoded frames according to the comparison relationship between the frame rate of the decoded frames and the target frame rate.

[0030] S130, obtaining the value of the frame data cached by the player.

[0031] S140, adjusting the decoding playback multiple according to the comparison relationship between the frame data value and the current input buffer threshold to adjust the input buffer of the decoded frames.

[0032] The method for real-time media stream playback provided by this application dynamically adjusts the input buffer threshold of the decoded frames based on the comparison relationship between the frame rate of the decoded frames and the target frame rate, and then dynamically adjusts the decoding playback multiple according to the comparison relationship between the true data value and the current input buffer threshold, so that the decoded and played media stream adapts to the current playback conditions, thereby realizing real-time media stream playback, reducing latency, improving the smoothness of media stream playback, and reducing frame freezes.

[0033] Among them, the frame rate (Frames Per Second, FPS) refers to the number of image frames displayed per second. Common frame rates include 24 fps (movies), 25 fps (PAL television standard), 30 fps (NTSC television standard), 60 fps, etc. The higher the frame rate, the better the video smoothness, but the file size will also increase.

[0034] In step S110, the target frame rate of the video source refers to the frame rate set by the video file itself, which is usually determined during video encoding and can be extracted through various tools or programming interfaces. The frame rate of the player's decoded frames refers to the number of frames that the player can decode and display during actual playback.

[0035] In step S120, the function of dynamically adjusting the input buffer threshold according to the comparison relationship between the frame rate of the decoded frames and the target frame rate can help optimize video playback performance and ensure that the player can process the video stream more stably, especially in cases where network conditions are unstable or hardware performance is limited.

[0036] Step S130 adopts different methods according to the player used to obtain the cached frame data (including the number of cached frames or the time length), such as obtaining the cached frame data through command-line tools, programming interfaces, or monitoring the buffer status output in the log. Determine a reasonable cache threshold as a reference point. This value should be large enough to ensure smooth playback without causing obvious delays. It can be adjusted according to factors such as network conditions and content type.

[0037] Step S140 periodically checks whether the frame data value (i.e., the current buffer level) is lower or higher than a set target threshold during playback, and dynamically changes the speed setting of the player based on the above comparison results to improve the playback smoothness and real-time performance of the media stream.

[0038] Combined with the first aspect, step S120 includes: S121, if the frame rate of the decoded frame is less than the target frame rate, increase the input buffer threshold of the decoded frame.

[0039] Specifically, if the frame rate of the decoded frame is less than the target frame rate, it indicates that the player may not be able to keep up with the speed of the video source. At this time, the input buffer threshold should be increased. This can allow more data to enter the buffer in advance and reduce the phenomenon of frame freezing caused by untimely decoding.

[0040] S122, if the frame rate of the decoded frame is greater than or equal to the target frame rate, decrease the input buffer threshold of the decoded frame.

[0041] Specifically, if the frame rate of the decoded frame is greater than or equal to the target frame rate, it indicates that the player can decode the video smoothly, even ahead of the speed set by the video source. At this time, the input buffer threshold should be decreased to avoid excessive data accumulation in the buffer, save resources and reduce latency.

[0042] Continue to monitor and dynamically adjust after the adjustment based on step S120 to ensure the best playback effect.

[0043] Combined with the first aspect, step S140 includes: S141, if the frame data value is greater than the current input buffer threshold, increase the decoding playback multiple.

[0044] Specifically, if the frame data value is greater than the current input buffer threshold, it indicates that the current buffer is too large. The playback rate can be increased by increasing the decoding playback multiple to speed up the buffer release speed. For example, play at a decoding playback multiple of 3 times.

[0045] S142, if the frame data value is less than or equal to the current input buffer threshold, use the preset decoding playback multiple as the target decoding playback multiple.

[0046] Specifically, if the frame data value is less than or equal to the current input buffer threshold, it indicates that the current buffer size is small or equal. The playback can be performed at a specified playback rate by maintaining the preset decoding playback multiple. In this embodiment, the preset decoding playback multiple is 1 time.

[0047] It can be seen that in this embodiment, if the frame rate of the decoded frame is greater than or equal to the target frame rate, the input buffer threshold of the decoded frame is lowered, and at the same time, the decoded playback multiple is adjusted according to the comparison relationship between the cached frame data value and the input buffer threshold, so as to adjust the playback rate to lower the input buffer of the decoded frame, thereby ensuring the real-time performance of playback and solving the problem of large playback delay.

[0048] If the frame rate of the decoded frame is less than the target frame rate, the input buffer threshold of the decoded frame is increased, and at the same time, the decoded playback multiple is adjusted according to the comparison relationship between the cached frame data value and the input buffer threshold, so as to adjust the playback rate to increase the input buffer of the decoded frame, thereby ensuring the smoothness of playback and reducing phenomena such as frame freezing.

[0049] Combined with the first aspect, specifically, increasing the decoded playback multiple in step S141 includes: S1410, calculating the difference between the frame data value and the current input buffer threshold.

[0050] S1411, determining the target decoded playback multiple based on the comparison relationship between the difference and multiple preset thresholds.

[0051] S1412, adjusting the current decoded playback multiple according to the target decoded playback multiple.

[0052] It can be understood that as the difference between the frame data value and the current input buffer threshold is different, the decoded playback multiple to be adjusted is also different. Therefore, first calculate the difference between the two, and then compare the difference with multiple preset thresholds to determine the threshold interval corresponding to the difference. Furthermore, based on the determined threshold interval, determine the target decoded multiple. Among them, the corresponding relationship between each threshold interval and the target decoded multiple is preset.

[0053] For example, 6 thresholds such as D 1 、D 2 、D 3 、D 4 、D 5 、D 6 are preset, and the corresponding 5 threshold intervals are D 1 ~D 2 、D 2 ~D 3 、D 3 ~D 4 、D 4 ~D 5 、D 5 ~D 6 . The decoded multiples corresponding to these five threshold intervals are A 1 、A 2 、A 3 、A 4 、A 5At this time, if the calculated difference is compared with the above six thresholds and the determined threshold interval is D 4 ~D 5 , and then the decoding multiple A 4 corresponding to this threshold interval is used as the target decoding multiple.

[0054] Combined with the first aspect, step S1412 includes: S14120, gradually increase the decoding and playback multiple until the target decoding and playback multiple is reached.

[0055] In this embodiment, the method of gradually increasing the decoding and playback multiple is adopted until the target decoding and playback multiple is reached, rather than adjusting it in one step. The advantage of doing this is to avoid the impact on the user experience caused by sudden changes, and it can also give the system enough time to respond and stabilize the new playback rate.

[0056] It can be understood that it can be adjusted step by step by presetting an adjustment step size. For example, if the current decoding and playback speed is 1 time and the target decoding and playback multiple is 2 times, and the adjustment step size is 0.5 times, then two adjustments are required. First, adjust it to 1.5 times, and then adjust it to 2 times.

[0057] In the second aspect, an embodiment of the present application provides a media stream real-time playback device. Combined with Figure 2 as shown, the device includes: a first acquisition module 10, a first adjustment module 20, a second acquisition module 30, and a second adjustment module 40.

[0058] The first acquisition module 10 is used to acquire the target frame rate of the video source and the frame rate of the player's decoded frames.

[0059] The first adjustment module 20 is used to adjust the input buffer threshold of the decoded frames according to the comparison relationship between the frame rate of the decoded frames and the target frame rate.

[0060] The second acquisition module 30 is used to acquire the frame data value of the buffer of the player.

[0061] The second adjustment module 40 is used to adjust the decoding and playback multiple according to the comparison relationship between the frame data value and the current input buffer threshold, so as to adjust the input buffer of the decoded frames.

[0062] In this embodiment, the first acquisition module 10 is used to acquire the target frame rate of the video source and the frame rate of the player's decoded frames to ensure that the video can be played as closely as possible to the frame rate standard set by the video source itself while monitoring the actual performance during the player's decoding process.

[0063] The first adjustment module 20 optimizes the input buffer strategy to reduce the phenomenon of playback jitter or large delay caused by network jitter and other situations, and improves the playback smoothness and real-time performance.

[0064] The second acquisition module 30 monitors in real time how many frames of data are stored in the current buffer of the player, that is, the buffer capacity, providing a basis for subsequent judgment on whether to adjust the playback rate to maintain an appropriate buffer level, avoiding frame freezes or even playback interruptions caused by too low a buffer, or large delays and excessive memory resource occupation caused by too high a buffer.

[0065] The second adjustment module 40 compares the buffer frame data value with the currently set input buffer threshold to decide whether and how to adjust the decoding playback multiple. When the buffer is insufficient, it appropriately reduces the playback rate to accumulate more frame data; conversely, it can increase the playback rate to improve real-time performance, but will not exceed the maximum playback multiple limit set by the user.

[0066] Combined with the second aspect, the first adjustment module 20 includes: a first buffer threshold adjustment module 21 and a second buffer threshold adjustment module 22 (as Figure 3 shown).

[0067] The first buffer threshold adjustment module 21 is used to increase the input buffer threshold of the decoded frame when the frame rate of the decoded frame is less than the target frame rate.

[0068] The second buffer threshold adjustment module 22 is used to decrease the input buffer threshold of the decoded frame when the frame rate of the decoded frame is greater than or equal to the target frame rate.

[0069] Combined with the first aspect, the second adjustment module 40 includes a first decoding playback multiple adjustment module 41 and a second decoding playback multiple adjustment module 42 (as Figure 4 shown).

[0070] The first decoding playback multiple adjustment module 41 is used to increase the decoding playback multiple when the frame data value is greater than the current input buffer threshold.

[0071] The second decoding playback multiple adjustment module 42 is used to use the preset decoding playback multiple as the target decoding playback multiple when the frame data value is less than or equal to the current input buffer threshold.

[0072] In a third aspect, an embodiment of the present application provides an electronic device. Combined with Figure 5 shown, the electronic device includes a memory 131 and a processor 130. The memory 131 is used to store a computer program, and the processor 130 runs the computer program to enable the electronic device to execute the above method.

[0073] Further, the electronic device combined with Figure 5 shown further includes a bus 132 and a communication interface 133. The processor 130, the communication interface 133, and the memory 131 are connected through the bus 132.

[0074] Among them, the memory 131 may include high-speed random access memory (RAM), and may also include non-volatile memory, such as at least one disk memory.

The bus 132 can be an ISA bus, a PCI bus, an EISA bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For the sake of representation, Figure 5 only a bidirectional arrow is used in Figure 5 , but it does not mean that there is only one bus or one type of bus.

[0075] The processor 130 may be an integrated circuit chip with signal processing capabilities.
