Can't transcode P2 AVC Intra 100 with ai12 fourcc #45

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
I have a P2 AVC Intra file that has been passed through Philip de Nier's (from 
BBC R&D) mxf2mov tool.
I then try to pass that output through FFmbc and it fails to transcode.

I'm using FFmbc-0.6-rc6 on both OS X and Centos Linux and see the same problem 
on both.

Full command line with output:
ffmbc -v 3 -i ~/Movies/post-transwrap.mov -f mp4 -y -vf scale=400:226 
-map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:2:0:0:1:1 -vcodec libx264 
-b 800k -r 25 -vf yadif -maxrate 800k -bufsize 5097k -ac 2 -acodec libfaac -ab 
96k -ar 48000 /tmp/transcode64930.mov

Mediainfo reports the fourcc as 'ai12' so I wonder if it's just a case of 
adding support for that fourcc.
I tried adding that fourcc to libavformat/isom.c but it didn't seem to fix the 
problem (I guess it's not as simple as that).

Thanks in advance, Darren.

Any plans on the roadmap? It's quite a widely used broadcast codec.
