[FFmpeg-user] Copy Audio

[Kieran O'Leary]

Hi,

So on OSX El Capitan - VLC 3.4, ffplay 4.1, mpv 0.29.1 will play back 16-bit twos within MP4. Quicktime player will not play back the file. VLC throws up an unsupported codec warning but it still plays it back.

$ ffplay '/Volumes/kieran_tests/zip_sip_outputs/aaa0013/2a215d97-39a7-4bf4-9ca6-46cd7fd766d8/objects/Card 5/BPAV/CLPR/432_4407_01/432_4407_01.MP4'
