Martin, thanks again, I find your comments very helpful. I will do some
more research to determine what the best CLI arguments would be.

I appreciate your feedback. Doing the decoder side first is a good
suggestion, I certainly want to start with whichever is easier. I
originally started with the encoder simply because of the limited number of
existing test files. However, I believe that GPAC is able to generate some.

Yes -- it was more a rather extreme example to remind, that this file

You're correct that I'm primarily interested in uncompressed data and not
raw bayer sensor data. However, it seems like the "-c:v rawvideo" option
is the convention in other formats to generate uncompressed video data. I'm
just trying to follow the pattern and reuse what is already there. If ther

Why do you choose the term "raw" instead of uncompressed?
Using this format for "raw" bayer CFA data is just one possible
application of ISO/
Sounds good, I will put together a complete implementation with crs tests

Does this warrant a new mpeg_rawenc.c file under /libavcodec? Or should an

Yes, I wanted to divide my contributions up into small sections that are
easy to review. However, this means that each contribution isn't a full
implementation which is why mov_write_uncC_tag() isn't called yet. Is this

Hello,
I attached the .patch so hopefully this is easier for you to apply. The
patch itself isn't very impressive, but is intended to be the first of a
series of contributions to generate uncompressed MP4 video. I'm hoping to
spark interest and receive some guidance on this task moving forward.

It's easier if you attach the patch normally so people can download and
apply it
