See #9.

mufunyo commented 5 years ago

I have found the following list of codecs that are supported by the QuickTime (MOV) container, which would be able to be copied without having to transcode them:

https://www.norpix.com/applications/applecodecs.php

Note that the list seems to be too old to include h.265/HEVC, which is also a supported codec in the MOV container.

I also found another list:

http://codec.kiev.ua/quicktime.html

Cross-referencing both lists, combined with some quick google-fu resulted in the following comprehensive list of ffmpeg vcodecs that should be supported by MOV when simply copied without transcoding:

For MP4, the list is much shorter, as only MPEG standardised codecs are supported as far as I know.

h261          H.261

hevc          HEVC (High Efficiency Video Coding)
mpeg1video    MPEG-1 video
mpeg2video    MPEG-2 video
mpegvideo     MPEG-1 video (codec mpeg2video)
mpeg4         MPEG-4 part 2

I think mpeg1/2 is not supported by MP4, at least when I tried to repackage some files with FFmpeg, using -c:v copy. But I'll give it a try.

Not true.... MP4 does support MPEG1/2 video:

See https://de.wikipedia.org/wiki/MP4

Function extended, --autocopy now supports:

Option Description
OFF Never copy streams, transcode always.
MATCH Copy stream if target supports codec.
MATCHLIMIT Same as MATCH, only copy if target not larger, transcode otherwise.
STRICT Copy stream if codec matches desired target, transcode otherwise.
STRICTLIMIT Same as STRICT, only copy if target not larger, transcode otherwise.
