[0047] 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. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] To facilitate understanding of this embodiment, the technical terms used in this application will be briefly introduced below.

[0049] Frame rate (Frames Per Second, FPS) refers to the number of images displayed per second. Common frame rates include 24 fps (movie), 25 fps (PAL TV standard), 30 fps (NTSC TV standard), and 60 fps. A higher frame rate results in smoother video playback, but also increases file size.

[0050] Decoding playback speed refers to the playback speed that is dynamically adjusted based on decoding and caching during video playback.

[0051] After introducing the technical terms used in this application, the application scenarios and design concepts of the embodiments of this application will be briefly described below.

[0052] Existing web players face a dilemma when playing media streams: setting a large cache for smoothness can lead to high latency in live streaming, while reducing the cache for real-time performance may cause stuttering when the network is poor, both of which affect the viewing experience.

[0053] Based on this, embodiments of this application provide a method, apparatus, electronic device, and storage medium for real-time playback of media streams.

[0054] Example 1

[0055] This application provides a method for real-time playback of media streams, combined with... Figure 1 As shown, the method includes:

[0056] S110, obtain the target frame rate of the video source and the frame rate of the player's decoded frames.

[0057] S120: Adjust the input buffer threshold of the decoded frame based on the comparison between the frame rate of the decoded frame and the target frame rate.

[0058] S130: Obtain the cached frame data values ​​of the player.

[0059] S140, adjust the decoding playback multiplier based on the comparison between the frame data value and the current input buffer threshold, so as to adjust the input buffer of the decoded frame.

[0060] The real-time media streaming playback method provided in this application dynamically adjusts the input buffer threshold of the decoded frame based on the comparison relationship between the frame rate of the decoded frame and the target frame rate. Then, based on the comparison relationship between the true data value and the current input buffer threshold, it dynamically adjusts the decoding playback multiplier so that the decoded media stream is adapted to the current playback conditions, thereby realizing real-time media streaming playback, reducing latency, improving the smoothness of media streaming playback, and reducing screen stuttering.

[0061] Frame rate (Frames Per Second, FPS) refers to the number of image frames displayed per second. Common frame rates include 24 fps (movie), 25 fps (PAL TV standard), 30 fps (NTSC TV standard), and 60 fps. A higher frame rate results in smoother video playback, but also increases file size.

[0062] 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 using 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.

[0063] In step S120, the function of dynamically adjusting the input buffer threshold based on the comparison between the frame rate of the decoded frame and the target frame rate can help optimize video playback performance and ensure that the player can process the video stream more stably, especially when the network conditions are unstable or the hardware performance is limited.

[0064] Step S130 employs different methods depending on the player used to obtain cached frame data (including the number of cached frames or the duration of the cache), such as through command-line tools, programming interfaces, or monitoring the buffer status output in logs. A reasonable cache threshold is determined as a reference point. This value should be sufficiently large to ensure smooth playback without causing noticeable delays. It can be adjusted based on factors such as network conditions and content type.

[0065] Step S140 periodically checks whether the frame data value (i.e. the current buffer level) is lower or higher than the set target threshold during playback, and dynamically changes the player's speed settings based on the comparison results to improve the smoothness and real-time performance of the media stream playback.

[0066] In conjunction with the first aspect, step S120 includes:

[0067] 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.

[0068] Specifically, if the frame rate of the decoded frame is lower than the target frame rate, it indicates that the player may not be able to keep up with the speed of the video source. In this case, the input buffer threshold should be increased. This allows more data to enter the buffer in advance, reducing stuttering caused by untimely decoding.

[0069] S122, If the frame rate of the decoded frame is greater than or equal to the target frame rate, lower the input buffer threshold of the decoded frame.

[0070] Specifically, if the frame rate of the decoded frames 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. In this case, the input buffer threshold should be lowered to avoid excessive data accumulation in the buffer, saving resources and reducing latency.

[0071] After adjustments based on step S120, continuous monitoring and dynamic adjustments are made to ensure optimal playback performance.

[0072] In conjunction with the first aspect, step S140 includes:

[0073] S141, If ​​the frame data value is greater than the current input buffer threshold, increase the decoding playback multiplier.

[0074] Specifically, if the frame data value is greater than the current input buffer threshold, it indicates that the current buffer is too large. In this case, the playback speed can be increased by increasing the decoding playback multiplier, thus speeding up the release of the buffer. For example, playback can be performed at a decoding playback multiplier of 3.

[0075] S142, if the frame data value is less than or equal to the current input buffer threshold, use the preset decoding playback multiplier as the target decoding playback multiplier.

[0076] 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, and playback can be performed at a specified playback rate while maintaining a preset decoding playback multiplier. In this embodiment, the preset decoding playback multiplier is 1.

[0077] As can be seen, 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. At the same time, the decoding playback multiplier 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 latency.

[0078] 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. At the same time, the decoding playback multiplier is adjusted according to the comparison between the cached frame data value and the input buffer threshold. This adjusts the playback rate to increase the input buffer of the decoded frame, thereby ensuring smooth playback and reducing stuttering.

[0079] In conjunction with the first aspect, increasing the decoding playback multiplier in step S141 specifically includes:

[0080] S1410, calculate the difference between the frame data value and the current input buffer threshold.

[0081] S1411, Based on the comparison relationship between the difference and multiple preset thresholds, determine the target decoding playback multiplier.

[0082] S1412, Adjust the current decoding playback multiplier according to the target decoding playback multiplier.

[0083] Understandably, the required decoding playback factor will vary depending on the difference between the frame data value and the current input buffer threshold. Therefore, the difference is first calculated, and then compared with multiple preset thresholds to determine the threshold range corresponding to that difference. Finally, the target decoding factor is determined based on the determined threshold range. The correspondence between each threshold range and the target decoding factor is preset.

[0084] For example, six thresholds are pre-defined, such as D1, D2, D3, D4, D5, and D6, corresponding to five threshold intervals: D1~D2, D2~D3, D3~D4, D4~D5, and D5~D6. The decoding multipliers corresponding to these five threshold intervals are A1, A2, A3, A4, and A5, respectively. If the calculated difference is compared with the above six thresholds and the determined threshold interval is D4~D5, then the decoding multiplier A4 corresponding to this threshold interval is taken as the target decoding multiplier.

[0085] In conjunction with the first aspect, step S1412 includes:

[0086] S14120, gradually increase the decoding playback multiplier until the target decoding playback multiplier is reached.

[0087] In this embodiment, the decoding playback multiplier is gradually increased until the target decoding playback multiplier is reached, rather than being adjusted all at once. This avoids the impact of sudden changes on the user experience and allows the system sufficient time to respond to and stabilize the new playback rate.

[0088] Understandably, you can adjust the speed gradually by setting the step size. For example, if the current decoding playback speed is 1x and the target decoding playback speed is 2x, and the adjustment step size is 0.5x, then you need to make two adjustments: first adjust it to 1.5x, and then adjust it to 2x.

[0089] Secondly, embodiments of this application provide 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.

[0090] 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.

[0091] The first adjustment module 20 is used to adjust the input buffer threshold of the decoded frame based on the comparison between the frame rate of the decoded frame and the target frame rate.

[0092] The second acquisition module 30 is used to acquire the cached frame data values ​​of the player.

[0093] The second adjustment module 40 is used to adjust the decoding playback multiplier based on the comparison between the frame data value and the current input buffer threshold, so as to adjust the input buffer of the decoded frame.

[0094] 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 decoding frame, so as to ensure that the video playback can match the frame rate standard set by the video source itself as much as possible, while monitoring the actual performance of the player during the decoding process.

[0095] The first adjustment module 20 optimizes the input caching strategy to reduce playback stuttering or delays caused by network jitter and other factors, thereby improving playback smoothness and real-time performance.

[0096] The second acquisition module 30 monitors in real time how many frames of data are currently stored in the player's cache, i.e. the cache size, to provide a basis for subsequent judgment on whether the playback rate needs to be adjusted, so as to maintain an appropriate cache level and avoid the screen stuttering or even playback interruption caused by too low a cache, or the large latency and excessive memory consumption caused by too high a cache.

[0097] The second adjustment module 40 compares the cached frame data value with the currently set input cache threshold to determine whether and how to adjust the decoding playback multiplier. When the cache is insufficient, the playback rate is appropriately reduced to accumulate more frame data; conversely, the playback rate can be increased to improve real-time performance, but it will not exceed the maximum playback multiplier limit set by the user.

[0098] In conjunction with the second aspect, the first adjustment module 20 includes: a first cache threshold adjustment module 21 and a second cache threshold adjustment module 22 (e.g., ...). Figure 3 (As shown).

[0099] 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.

[0100] The second buffer threshold adjustment module 22 is used to lower 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.

[0101] In conjunction with the first aspect, the second adjustment module 40 includes a first decoding playback multiplier adjustment module 41 and a second decoding playback multiplier adjustment module 42 (e.g., Figure 4 (As shown).

[0102] The first decoding playback multiplier adjustment module 41 is used to increase the decoding playback multiplier when the frame data value is greater than the current input buffer threshold.

[0103] The second decoding playback multiplier adjustment module 42 is used to set a preset decoding playback multiplier as the target decoding playback multiplier when the frame data value is less than or equal to the current input buffer threshold.

[0104] Thirdly, embodiments of this application provide an electronic device, combined with Figure 5 As shown, the electronic device includes a memory 131 and a processor 130. The memory 131 stores a computer program, and the processor 130 runs the computer program to make the electronic device perform the above-described method.
