detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides a method for playing media data. Referring to FIG. 1, in an embodiment, the method for playing media data includes:

Step S101, when the client of the terminal detects that the code rate switching needs to be performed, clearing the media data buffered by the client and sending a request for acquiring new media data to the server;

In this embodiment, the terminal may be a television, a computer, a tablet computer, a mobile phone, or the like.

In this embodiment, the client of the terminal acquires media data from the server and caches the data, and then sends the cached media data to the player for playing.

In this embodiment, the client responds to the user's operation, creates a play instance and requests media data from the server, and the server responds to the client request to media data in the elementary stream (Elementary Streams, ES) is sent to the client, and the elementary stream may contain one or more of video, audio, subtitles, and the like.

In this embodiment, when the client detects that code rate switching is required, for example, when the current bandwidth is insufficient or the playback performance of the terminal is insufficient, rate switching is required. The client empties the media data currently cached by itself to re-receive the media data sent by the server.

In this embodiment, when detecting whether the rate switching needs to be performed, the client can detect whether to switch from a high code rate to a low code rate or a low code rate to a high code rate. A request to obtain corresponding media data is then sent to the server.

Step S102, obtaining a current code rate, and calculating a current data volume buffer rate Rs and an average code rate buffer time ratio Rt according to the code rate;

In this embodiment, the current data buffer rate Rs refers to the ratio of the currently buffered data amount S to the set cache data amount maximum value Ms:

,

If the current network speed is faster, the larger the current cached data amount S is, the larger the current data buffer rate Rs is, and the currently buffered data amount S is proportional to the current code rate, and therefore, according to the current The code rate is calculated to obtain the current buffered data amount S.

In this embodiment, the average bit rate buffer time ratio Rt refers to the ratio of the buffer data average code rate time T to the set cache maximum time Mt:

,

If the current network speed is faster, the accumulated buffer data amount is faster, and the buffer data average code rate time T is inversely proportional to the current code rate, that is, the buffer data average code rate time T is smaller, and thus the average bit rate is The smaller the cache time ratio Rt.

The buffering strategy of this embodiment is based on the ratio of the current data volume buffer rate Rs and the average code rate buffer time ratio Rt.

Step S103, receiving and buffering new media data sent by the server, and determining, according to the current data volume buffer rate Rs and the average code rate buffer time ratio Rt, whether the new media data buffered by the client reaches a preset value;

In this embodiment, the client receives the new media data sent by the server and caches it, and the client caches the new media data in a specific sample format, and each sample is independent, including descriptions of the new media data and the new media data. Dts, duration and other information.

In this embodiment, at the current code rate, the client receives the new media data sent by the server, and then determines the new media cached by the client according to the current data volume buffer rate Rs and the average code rate buffer time ratio Rt calculated above. Whether the data reaches the preset value.

In this embodiment, if the current data volume buffer rate Rs reaches 100% or the average code rate buffer time ratio Rt reaches 100%, it is considered that the new media data buffered by the client has reached the preset value, and the playback can be restarted.

Step S104: If the current data volume buffer rate Rs reaches 1 or the average code rate buffer time ratio Rt reaches 1, the buffered new media data is sent to the player for playing.

In this embodiment, the player is preferably a gstreamer player, and the gstreamer is a multimedia framework library for creating streaming media applications, which can provide functions for constructing various media function components, including simple audio playback, audio and video. For playback, recording, streaming and audio editing, you can also create many multimedia applications such as video editors, streaming media and media players.

In this embodiment, one of the current data volume buffer rate Rs or the average code rate buffer time ratio Rt reaches 100% first, then the client cache is completed, and the client sends the play information to the player to notify the player to restart. Play, the player creates a pipe and starts playback, and requests new media data from the client.

In this embodiment, media data of different sources is divided. The player requests media data from the client in a special request format, and the request format specification section contains the media data that needs to be requested and the number of media data requested. Regardless of whether it is a client or a player, media data of different sources are independently requested and independently stored, so that media data of different sources can be processed separately. The player side saves the media data of different sources in different queues in a specific format, and sequentially obtains media data from the data queues in order according to the order of the media data requests, keeps the data synchronized and does not cause a certain way. The accumulation of media data.

Compared with the prior art, when the client detects that the code rate switching needs to be performed, the acknowledgment is whether the high code rate is switched to the low code rate or the low code rate is switched to the high code rate, and then according to the current code rate. Calculating the current data volume buffer rate Rs and the average bit rate buffer time ratio Rt, that is, whether the amount of new media data buffered by the client reaches a preset value by using the buffer amount or the buffer time, as long as one of them reaches the preset value If the client cache is completed, the player can restart the playback. In this embodiment, according to the cache amount or the cache time of the client, the cache policy is used. Whether the bandwidth is insufficient or the playback performance of the terminal is insufficient, the playback can be restarted quickly. Make the playback better.

In a preferred embodiment, as shown in FIG. 2, based on the foregoing embodiment of FIG. 1, the foregoing step S102 includes:

Step S1021, acquiring the current code rate, the set cache data amount maximum value Ms, and the set cache maximum time Mt;

Step S1022: Calculate a current data volume buffer rate Rs according to the code rate and the set cache data amount maximum value Ms: and calculate an average code rate buffer time ratio Rt according to the code rate and the set cache maximum time Mt: .

In this embodiment, the current data buffer rate Rs:;S is the current buffered data amount, and Ms is the set cache data amount maximum, wherein the currently buffered data amount S is the current code rate A and the buffer time x. Product of: S=A*x.

In this embodiment, the set cache maximum time Mt:; T is the cache data average code rate time, and Mt is the set cache maximum time.

Preferably, the buffered data average code rate time T is the ratio of the currently buffered data amount S to the average code rate A: T=S/A.

The average code rate A is the average of the code rate per unit time and the old average code rate v, wherein the code rate per unit time refers to the ratio of the received media data to the reception time in the set unit time:

The old average code rate v refers to the average code rate value calculated in the previous period of time. This period is set to N. When the buffer time exceeds N, the average code rate A formula is:

.

In a preferred embodiment, as shown in FIG. 3, based on the foregoing embodiment of FIG. 1, the foregoing step S103 includes:

Step S1031, comparing the current data volume buffer rate Rs and the average code rate buffer time ratio Rt, and obtaining the larger of the current data volume buffer rate Rs and the average code rate buffer time ratio Rt;

Step S1032, when the value of the larger one reaches 1, obtaining a time value corresponding to the value of the larger one reaching 1;

Step S1033: Determine whether the time of the new media data buffered by the client reaches the time value, to determine whether the new media data buffered by the client reaches a preset value.

In this embodiment, a buffer time x is preset, and then the current data volume buffer rate Rs and the average code rate buffer time ratio Rt are calculated, when the current data volume buffer rate Rs and the average code rate buffer time ratio Rt are two ratios. When one of the first reaches 100%, it is considered that the new media data cached by the client reaches the condition for restarting playback.

For example, suppose that it is a scene of mixed audio and video playback. The maximum amount of cached data set by the client is 2M, and the cache time is x (the client clears the cache and sends a request for obtaining new media data to the server for the cache time). Starting point), the current code rate is 1.5M (for the convenience of calculation, assuming that the code rate does not fluctuate), the current data volume buffer rate Rs and the average code rate buffer time ratio Rt are respectively in the buffer time x after the code rate is switched. :

;

At this time, if the current code rate is reduced to 0.2M (assuming the code rate does not fluctuate), then both are:

The above data can be seen that the current data volume buffer rate Rs will be the first to be cached up to 100% before the rate change, and the time when the current data volume buffer rate Rs reaches 100% is the time of the new media data cached by the client. At this time, the playback is restarted, and the playback can be started quickly after the bit rate is switched;

After the bit rate is decreased, the buffer time ratio Rt at the average bit rate first reaches 100%, and the time when the buffer time ratio Rt reaches 100% at the average code rate is the time of the new media data buffered by the client, when the time is reached. , restart playback, you can quickly start playback after the bit rate is switched.

In a preferred embodiment, as shown in FIG. 4, on the basis of the foregoing embodiment of FIG. 1, before the step S101, the method includes:

Step S100: During the playing of the media data by the player, the client detects whether the bandwidth changes or detects whether the code rate switching instruction sent by the player is received.

In this embodiment, the playback performance of the terminal is sufficient, and the client detects whether the bandwidth changes, that is, whether the bandwidth is changed from large to small or from small to large. When the bandwidth is changed and the rate is switched, the client initiates the code. Rate switching. At the rate switching, the client clears the cache and requests new media data from the server, while sending a pause play command to the player.

When the bandwidth of the network is sufficient, but the playback performance of the terminal is insufficient, such as a mobile phone client, the performance of the CPU may be sufficient but the performance of the decoder is insufficient, resulting in a high-rate video cannot be played. For this case, by the player Sending a code rate switching instruction to notify the client that the playback performance of the player is insufficient. After receiving the code rate switching instruction, the client determines that the code rate switching is because the code rate is too high but the playback performance of the terminal is insufficient, causing the playback to fail, and then The client initiates the entire bit rate switch.

In this embodiment, considering that there are many cases where rate switching occurs, it is impossible for the terminal to define a caching policy for each case, which will become complicated. In this embodiment, the current data volume buffer rate Rs and the average code rate buffer time ratio Rt are the basis of the client cache policy, and the problem can be solved simply and reasonably.
