Method, apparatus, electronic device and storage medium for video bitrate switching

An electronic device comprising:

• one or more processors, and
• a storage device configured to store one or more programs,
• the one or more programs when executed by the one or more processors, causing the one or more processors to implement operations, the operations comprising:
• in response to a determination that a condition for video bitrate switching is satisfied, determining a target video bitrate to be switched to;
• determining, based on a playback time of a delivered audio and video frame, target switching data for switching to a target video stream corresponding to the target video bitrate;
• in response to a determination that an audio and video frame to be delivered is consistent with the target switching data, delivering audio and video frames in the target video stream to a client in sequence;
• and
• in response to a determination that a timestamp of the audio and video frame to be delivered is inconsistent with a target switching timestamp of the target switching audio and video frame in the target switching data, sending audio and video frames to be delivered corresponding to an original video bitrate to the client, wherein the original video bitrate is a bitrate before switching to the target video bitrate.

A non-transitory storage medium comprising computer-executable instructions, the computer-executable instructions when executed by a processor of a computer, configured to perform operations, the operations comprising:

• in response to a determination that a condition for video bitrate switching is satisfied, determining a target video bitrate to be switched to;
• determining, based on a playback time of a delivered audio and video frame, target switching data for switching to a target video stream corresponding to the target video bitrate;
• in response to a determination that an audio and video frame to be delivered is consistent with the target switching data, delivering audio and video frames in the target video stream to a client in sequence;
• and
• in response to a determination that a timestamp of the audio and video frame to be delivered is inconsistent with a target switching timestamp of the target switching audio and video frame in the target switching data, sending audio and video frames to be delivered corresponding to an original video bitrate to the client, wherein the original video bitrate is a bitrate before switching to the target video bitrate.
