Hi,
There are too many ffmpeg functions. I want to find one function, which can

Thanks!

Hi,
I intend to use avcodec_decode_audio4(). below is url link of the function

where, decoder will allocate a buffer for decoded frame.
Does it mean, decoder will allocate a buffer once

But when I use avcodec_encode_audio2() to encode audio frames, and audio codec
is AV_CODEC_ID_AAC, I can't get pts/dts after returning from the function. Why?
Doesn't ffmpeg support this fu

will get... P or B frame, hence partial image.
I've never done this, I can't tell you how to do this, sorry.
Good luck!

dts/pts/duration of output packets itself? Or I'll calculate those timestamp
values by using other method? Does ffmpeg provide examples to
