Audio and video data processing method, live streaming apparatus, electronic device, and storage medium

A live streaming apparatus, comprising an audio processing module, a device interface module, and a processor module, wherein the audio processing module comprises an audio input interface and an audio processing chip;

• the audio input interface is connected to a microphone;
• the audio processing chip is connected to each of the audio input interface, the device interface module, and the processor module;
• the audio processing chip performs noise reduction and/or audio mixing processing on the audio data input by the audio input interface and/or the device interface module, and transmits the processed audio data to the processor module;
• the processor module comprises a timestamp homogenization processing unit;
• the timestamp homogenization processing unit comprises an acquisition module, a determination module, a compensation module, an adjustment module, and an output module;
• the acquisition module is connected to the determination module;
• the determination module is connected to the adjustment module;
• the adjustment module is connected to the compensation module;
• the compensation module is connected to the output module;
• wherein the acquisition module, the determination module, the compensation module, the adjustment module, and the output module have instructions that are executed by the processor module;
• the acquisition module is configured to acquire a media stream, the media stream being an audio and video stream;
• the determination module is configured to acquire a difference value between a current media frame timestamp and a previous media frame timestamp and an upper and lower limit range of the difference value, and determine whether the difference value is within the upper and lower limit range;
• and the output module outputs the current media frame timestamp as a current media frame target timestamp in a case that a determination result is Yes;
• the compensation module is configured to acquire a standard media frame interval of the media stream, and the adjustment module is configured to update the current media frame timestamp to a sum of the previous media frame timestamp and the standard media frame interval in a case that a determination result is No;
• the determination module is further configured to determine whether the difference value is greater than the standard media frame interval;
• the compensation module performs forward compensation on the updated current media frame timestamp according to a compensation coefficient in a case that the determination result is Yes;
• the compensation module performs reverse compensation on the updated current media frame timestamp according to a compensation coefficient in a case that the determination result is No;
• and
• the output module is configured to output a timestamp after the forward compensation or the reverse compensation as a current media frame target timestamp.
