Support muxing of non-AVCI h264 in mxf

Description

Summary of the bug:

I'm currently fiddling around with h264 based dcinema mxf
For reproduction I uploaded (a working and tested dcinema file) dcinema-h264.mxf to upload.ffmpeg.org/incoming/

Now I'm trying to create my own video from scratch but I didn't succeed with encoding my own video file. So I decided to extract the video and repack it into a new mxf - but this approach failed, too. Am I doing something wrong or is there an issue with ffmpeg's mxf muxer?

Attached "-report log" file

Regards,

Andreas


How to reproduce:

First - extract h264 from mxf:

andreas@notebook:/tmp$ ffmpeg -i dcinema-h264.mxf -vcodec copy video.h264
This works perfectly well and video.h264 is obviously a valid video file and plays with eg. ffplay

Second - remux this very same h264 to mxf:

andreas@notebook:/tmp$ ffmpeg -i video.h264 -vcodec copy dcinema-test.mxf

Hi Andreas,

if you could provide me with a valid sample MXF file that does not contain baseline H.264 I could have a look at adding other codecs to the muxer.
