> Do you know if there is a way to compute the MD5 of the streams with
FFmpeg '''before''' decoding? A full file checksum is not an option
because I need to be able to select only some streams for the calculation.
{{{
./ffmpeg -i h264_720p_hp_3.1_600kbps_aac_mp3_dual_audio_harry_potter.mkv
-vn -c:a copy -f md5 -
}}}
Should give you the md5 of the aac stream as it is stored in the file,
without decoding it.
