With this patch, I was able to use the following command to generate an
uncompressed mp4:
$ ffmpeg -i input.mp4 -c:v rawvideo -pix_fmt rgb24 -tag:v uncv
out.mp4
The output file successfully played in GPAC.
My first question is whether to reuse the existing AV_CODEC_ID_RAWVIDEO, or
if a br
Martin, thanks again, I find your comments very helpful. I will do some
more research to determine what the best CLI arguments would be.

If ISO/IEC 23001-17:2024 requires its own .c file, then perhaps that
filename should use the term "uncompressed" instead of "raw". For example,
mpeg_unc_enc.c

Sounds good, I will put together a complete implementation with crs tests
for submission. Once completed, I envision the following command to work:
$ ffmpeg -i input.mp4 -c:v rawvideo output.mp4
Does this warrant a new mpeg_rawenc.c file under /libavcodec? Or should an
existing file be extende
x27;t called yet. Is this
an appropriate approach?
As suggested, this next patch uses av_pix_fmt_desc_get() to get the
nb_components
What is considered sufficient for testing? Is this done by running fate?

Hello, I'm implementing ISO/IEC 23001-17:2024 (MPEGs uncompressed codec)
and am looking for an FFmpeg developer to review/approve my contributions.
I started by writing the uncC box:

Hello,
This patch is more of a RFC. I'm interested in generating uncompressed MP4
files in FFMPEG according to ISO/IEC 23001-17:2024 and wrote this as a
first step towards implementation. Any feedback or help would be greatly
appreciated.
Thanks

ar, it
has already gained significant momentum and will likely become the de facto
general-purpose option for uncompressed media, given that it was developed
and is maintained by an accredited international standards organization.
Thanks,

Hopefully this capability will be added to FFmpeg soon.

Hello,
I'm interested in implementing uncompressed MP4 parsing according to the
newly released ISO/IEC 23001-17:2024. Would anyone be interested in further
discussing this with me?
Thanks,
