Comment (by rmk):
Replying to [comment:4 Cigaes]:
> “provided they are out there in the wild and not from a crazy source” is
for reading non-standard files. This is indeed ffmpeg's policy. And ffmpeg
can read your file.

> For writing, that would be something like “provided there is a genuine
need for it”.
That's of course a grey area but as I do not have a strong case myself
other than "why is it not possible like with other camera files", I think
that position is generally a good thing.

and “twos” that look like uncompressed PCM.
That's interesting.You mean there would actually be potential for
confusion between a jpeg2000 video sample description and that of raw
audio? That would be messy indeed. Thanks for the info.
