Based on the analysis in the previous two articles, frames are divided into tag frames and data frames. The MP3 file types are divided based on the data frame types. The file types are shown in the following table:   Equal bit rate

Av_rescale_q is used to calculate the PTS for packet. The return value of Av_rescale_q is a large integer, and the result interval for each calculation is very large. Unlike Avcodec_encode_video, the PTS (Small integer and small interval) that

Audio Stream (proportion of redundant data): Let's take a brief look at the structure of the ADTS header: 1) The ADTS header is at the beginning of each AAC frame and is typically 7 bytes long (or 9 bytes, not seen). 2) The length of each AAC frame
