Hi Martin,
For my point of view, the AVFrame contains the colorspace for each frame,
which can be different (maybe not volunteer..).
The colorspace in AVCodecContext is the "pre-computed" colorspace, used to
generate the output file, as header/footer of wrappers can require
colorspace informations

If i correctly understand (which is not sure :-) :
the colorspace for AVCodec
I have updated the patch with our discussion.
It took information only from the codec context.

For me it's the only codec who use picture colorspace as source.
All others uses only the CodecContext.
I don't know the exact reason, but I suppose it can be easiest to manage
output colorspace during merge of video, as a video can have only one
"static" video colorspace.
So for me it made sense

In our case we have some files with bad colorspaces (in HD but with bt601
colorspace).
So we use -colorspace, -color_trc, -color_primaries to force the output
colorspace.
We keep compatibility with "old command line", we get source colorspace if
nothing is mentionned.
It work like that for Mpeg2vi

IIRC this patch is not needed.
