With this patch, I can generate an uncompressed mp4 without specifying the
-c:v rawvideo option:
$ ffmpeg -i input.mp4 -c:v rawvideo -pix_fmt rgb24 output.mp4
Originally, it was failing the mux.c validate_codec_tag() function and
never reached mov_get_rawvideo_codec_tag(). I found the followi

This updated patch registers the 'uncv' tag in the isom_tags.c
ff_codec_movvideo_tags[] list. However, I still need to specify the tag
with the "-tag:v uncv" option. I hoped this change would set 'uncv' as the
default tag for raw mp4 video, but I'm not sure what the issue is.
I'm also looking into

video with many components is an important use case.
Yes, there are various interl

With this patch, I was able to use the following command to generate an
uncompressed mp4:
$ ffmpeg -i input.mp4 -c:v rawvideo -pix_fmt rgb24 -tag:v uncv
