[FFmpeg-devel] [PATCH] avformat/mov.c: Fix to allow custom udta tags through when export_all option specified.

[FFmpeg-devel] [PATCH] avformat/mov.c: Fix to allow custom udta tags through when export_all option specified.

[Ken McGaugh]

Hi, first time contributing to ffmpeg so I hope I got this right. We use
custom udta tags in our pipeline but they were not coming through
correctly. Looks like they were incorrectly being routed through the code
path for "raw" data.

Would it be possible for you to share a small sample?
