Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 1, fig. 1 is a schematic flowchart of an audio and video synchronization method according to an embodiment of the present invention. As shown in fig. 1, an audio and video synchronization method provided by an embodiment of the present invention includes the following steps:
s101, acquiring the playable time length of audio data;
it should be noted that the main execution body of the method is a terminal, and may be an electronic device such as a smart phone, a tablet computer, an intelligent wearable device, a computer, and the like.
Specifically, the terminal may be equipped with a client having a network communication function. The audio data stream reaches the client through the network, and then the received audio data stream is stored in the buffer zone. The time during which the audio data can be played is then determined according to the size of the audio data stream stored in the buffer.
S102, acquiring the playable time length of video data;
receiving a video data packet transmitted by a network, storing the received video data packet in a buffer area, and determining the playable time length of the video data according to the size of the video data packet in the buffer area.
S103, if the playable time length of the audio data is longer than a first preset time length and the playable time length of the video data is longer than the first preset time length, audio and video synchronous playing is carried out.
It should be noted that the first preset duration may be a default length of the terminal, or may be a duration recommended by a client manufacturer.
Optionally, the length of the first preset duration may be adjusted according to a network condition. For example, if the wire speed is greater than 1M/S, the first preset time period may be 10S; if the wire speed is less than 1M/S, the first preset duration may be 20S.
Specifically, the faster the network speed is, the shorter the first preset duration may be; the slower the wire speed, the longer the first preset duration. Therefore, smooth synchronous playing of audio and video can be ensured.
It should be noted that, if the network speed is less than the preset threshold, the audio and video is automatically switched to the pause state.
Optionally, the terminal may adjust the audio/video playing speed according to the audio data buffering speed and the video data buffering speed. For example, if the audio data is loaded fast and the video data is loaded slowly, the video data can be adjusted to be played at an accelerated speed so as to enable the audio and video to be synchronous; if the video data is loaded fast and the audio data is loaded slowly, the audio data can be adjusted to be played at high speed so as to enable the audio and video to be synchronous.
Optionally, if the playable time length of the audio data is longer than the first preset time length and the playable time length of the video data is shorter than the first preset time length, it may be determined that the audio is in a playable state at this time, and it is necessary to detect whether a video data packet is received;
if the video data packet is received, judging whether the timestamp of the first frame of video to be played of the received video data packet is matched with the timestamp of the audio to be played;
if the time stamp of the first frame of video to be played is matched with the time stamp of the audio to be played, audio and video synchronous playing is carried out;
if the timestamp of the first frame of video to be played is not matched with the timestamp of the audio to be played, calculating the time difference between the timestamp of the first frame of video to be played and the timestamp of the audio to be played; if the time stamp of the first frame of video to be played is later than the time stamp of the audio to be played, determining a target audio time point according to the audio with the time difference length; skipping audio data before the target audio time point, and starting to play with the received video data packet synchronously from the target audio time point.
If the time stamp of the first frame of video to be played is earlier than the time stamp of the audio to be played, determining a target video time point according to the video with the time difference length; skipping video data before the target video time point, and starting to play the video data from the target video time point synchronously with the audio to be played.
Optionally, if the playable time length of the audio data is less than the first preset time length and the playable time length of the video data is greater than the first preset time length, at this time, it is determined that the video data is in a playable state, and then it is detected whether an audio data packet is received;
if the audio data packet is received, judging whether the timestamp of the first frame of audio to be played of the received audio data packet is matched with the timestamp of the video to be played;
and if the time stamp of the first frame of audio to be played is matched with the time stamp of the video to be played, carrying out audio and video synchronous playing.
If the timestamp of the first frame of audio to be played is not matched with the timestamp of the video to be played, calculating the time difference between the timestamp of the first frame of audio to be played and the timestamp of the video to be played;
if the time stamp of the first frame of audio to be played is later than the time stamp of the video to be played, determining a target audio time point according to the video with the time difference length; skipping video data before the target video time point, and starting to play with the received audio data packet synchronously from the target video time point.
If the time stamp of the first frame of audio to be played is earlier than the time stamp of the video to be played, determining a target audio time point according to the audio of the time difference length; skipping the audio data before the target audio time point, and starting to play the audio data from the target audio time point synchronously with the video to be played.
Optionally, if the playable time length of the audio data is less than the first preset time length and the playable time length of the video data is less than the first preset time length, the audio data is considered to be in a pause state at this time, and since the audio and video data cannot be played, it is required to detect whether a new audio data packet or a new video data packet is received; and if a new audio data packet or a new video data packet is received, determining the playable time length of the audio data or the playable time length of the video data according to the received new audio data packet or the received new video data packet.
It can be seen that, in the scheme of the embodiment of the invention, the playable time length of the audio data is obtained; acquiring the playable time length of video data; and if the playable time length of the audio data is longer than a first preset time length and the playable time length of the video data is longer than the first preset time length, carrying out audio and video synchronous playing. Therefore, by implementing the technical scheme provided by the invention, the audio and video playing progress can be adjusted according to the playable data of the audio and the playable data of the video, so that the synchronous playing of the audio and the video is ensured.

As shown in fig. 2, another audio and video synchronization method provided by another embodiment of the present invention may include the following steps:
s201, acquiring the playable time length of audio data and the playable time length of video data;
it should be noted that the main execution body of the method is a terminal, and may be an electronic device such as a smart phone, a tablet computer, an intelligent wearable device, a computer, and the like.
Specifically, the terminal may be equipped with a client having a network communication function. The audio data stream reaches the client through the network, and then the received audio data stream is stored in the buffer zone. The time during which the audio data can be played is then determined according to the size of the audio data stream stored in the buffer. Receiving a video data packet transmitted by a network, storing the received video data packet in a buffer area, and determining the playable time length of the video data according to the size of the video data packet in the buffer area.

it should be noted that, if the time stamp of the first frame of video to be played is later than the time stamp of the audio to be played, which indicates that the audio is slow to be played, a part of audio data needs to be skipped over to determine the audio time stamp matched with the video time stamp.
S208, if the time stamp of the first frame of video to be played is earlier than the time stamp of the audio to be played, determining a target video time point according to the video with the time difference length; skipping video data before the target video time point, and starting to play the video data from the target video time point synchronously with the audio to be played.
