HI Luca, Thanks for the answer. I went to check how the ffmpeg program
computes the DTS and the PTS because i compute them the same way. I did
print it and got the same results but the difference is that ffmpeg
writes into the file. Now if the DTS and PTS have AV_NOPTS_VALUE, does
the avcodec_decode_audio2 decodes 2 frames or more at the same time?
