Using ffmpeg, after gathering the voice of the cache and transcoding voice-CodePudding

AVAudioFifo used for cache cache but later there will be slight zi zi zi's voice, then have bigger noise after transcoding, change the sampling rate,

 AVFrame * SpeakerCapture: : AllocAudioFrame () 
{
AVFrame * frame=av_frame_alloc (); 
if (! Frame) 
{
CLog: : GetInstance (). The Log (ENUM_LOG_LEVEL: : enum_Log_Level5, _T (" Could not the allocate frame ")); 
return NULL; 
} 

Frame - & gt; Nb_samples=1058; 
Frame - & gt; Channels=m_pFrameSrc - & gt; Channels; 
Frame - & gt; Channel_layout=av_get_default_channel_layout (m_pFrameSrc - & gt; Channels); 
Frame - & gt; Format=m_pCodecCtx - & gt; Sample_fmt; 
Frame - & gt; Sample_rate=m_pFrameSrc - & gt; Sample_rate; 

Av_frame_get_buffer (frame, 0); 
Return the frame; 
}

This is to cache avframe temporary variables don't know if this reason, and then use swr_convert resampling, do not know to have good method can eliminate the?
