FFmpeg documentation says "For video, the packet contains exactly one frame. For audio, it contains an integer number of frames if each frame has a known fixed size (e.g. PCM or ADPCM data). If the audio frames have a variable size (e.g. MPEG audio), then it contains one frame."
1. Regarding video, does av_read_frame() return anything other than I-frame,
P-frame or B-frame?
2. Regarding audio, what is the definition of audio frame? If I say, an audio frame contain one audio sample, is it correct?
Many thanks in advance.
