Decode function does not work for Ultra hdr images created on pixel 6 pro about libultrahdr

[ram-mohan]

thank you for raising this issue. can you please try if the above patch set works for you

[mcDandy]

It works, thank you.
I am however unable to open result raw (which has expacted size) and when converting back to jpeg, it looks wierd (red stripes and dots every other pixel on top of what appears to be a luminance map made up of mostly yellow and purple patches)

[ram-mohan]

The output is raw rgb data with r, g and b holding 10 bits per pixel and 2 for alpha which are currently null. the pixel format is x2bgr10le.
ffplay-f rawvideo -video_size 4080x3072 -pixel_format x2bgr10le -i outrgb.raw should help

[mcDandy]

I probably have wierd version of ffmpeg... (4.4.2-0ubuntu0.22.04.1)

[rawvideo @ 0x7efbac000cc0] No such pixel format: x2bgr10le.

Also is there any way to encode the file back to jpeg after editing it?
ultrahdr_app -m 0 -p outrgb.raw -C 1 uses wrong pixel format (result in my last post).

That is an older version of ffmpeg. You can get an updated one here, https://github.com/ffbinaries/ffbinaries-prebuilt/releases.

currently the encoder library does not take in rgb input. So for now it is not possible. Having said that, we are working on few changes that would resolve this. very soon
