#10001 new defect
mxf muxer writes the wrong bit depth and uses the CDCI essence descriptor UL instead of the RGBA essence descriptor UL for Full Range RGB48 MJPEG2000

Description
Summary of the bug:
When muxing a MJPEG2000 RGB Full Range stream, the mxf muxer is using the CDCI essence descriptor UL instead of the RGBA essence descriptor UL.
In other words, it's using
{ { 0x06,0x0e,0x2b,0x34,0x02,0x53,0x01,0x01,0x0d,0x01,0x01,0x01,0x01,0x01,0x28,0x00 }, mxf_read_generic_descriptor, sizeof(MXFDescriptor), Descriptor }, /* CDCI */
instead of
{ { 0x06,0x0e,0x2b,0x34,0x02,0x53,0x01,0x01,0x0d,0x01,0x01,0x01,0x01,0x01,0x29,0x00 }, mxf_read_generic_descriptor, sizeof(MXFDescriptor), Descriptor }, /* RGBA */
On top of this, the mxf muxer adds the color sampling descriptor as 4:4:4 which doesn't make sense as it's RGB, not YUV.
Last but not least, instead of writing 10bit for 10bit RGB sources and 12bit for 12bit RGB sources, it always writes 16bit, which of course is also wrong.
This results from the fact that FFMpeg is trying to the first compatible match when there is no colr atom.
How to reproduce:
1) Download the standard IMF evaluation package from here: https://aswf-dpel-assets.s3.amazonaws.com/asc-stem2/IMF/StEM2_TST_SDR_Rec709_IMF_App2e_Lossy.zip
2) Create the final mxf file by reading the CPL with FFMpeg like ffmpeg.exe -f imf -i "CPL.xml" -c:v copy -c:a copy -f mxf -y "IMF.mxf"
3) Check the resulting file: it was supposed to be rgb48le 10bit BT709, however the muxed file has all the above mentioned things wrong: wrong bit depth inside the container, CDCI wrongly populated instead of RGBA, causing it to be interpreted as YUV 4:4:4 16bit by other softwares other than ffmpeg and ffprobe themselves.

Please provide the command line you tested together with the complete, uncut console output to make this a valid ticket.

Just looking at the code it appears the muxer indeed always writes CDCIDescriptor, never RGBADescriptor. AV_PIX_FMT_FLAG_RGB needs to be checked for this, and the muxer is currently not really architectured for this. A stop gap would be to error out if the essence is RGB, until a proper solution is written.
I'm working on j2k stuff lately, so it's possible I may get some time to fix this.

Hi Tom,
please don't make it error out as I'm currently using the remux after reading the CPL in an automated fashion as I have a workflow based on that.
It's basically FFMpeg that reads the CPL and remuxes to .mxf and then Avisynth indexes it and gets it ready to encode to XAVC with x264, so if it errors out it would break my workflow.
I would say to wait until a proper fix is implemented, but thank you for looking into that, Thomas! :)

Without having to download the whole huge package, I created a fake ("broken or empty index" warning must be ignored) small file "RGBA_example.mxf".

But the issue is in the produced file, not visible in the FFmpeg output. With

12A8 CDCI Essence Descriptor (312 bytes) 12A8 Header (20 bytes) 12A8 Code (16 bytes) 12A8 Start (0x06): 6 (0x06) 12A9 Length of the remaining key (0x0E): 14 (0x0E) 12AA ISO, ORG (0x2B): 43 (0x2B) 12AB SMPTE (0x34): 52 (0x34) 12AC Category: 2 (0x02) - Group (Set/Pack) 12AD Registry: 83 (0x53) - 2-byte tag, 2-byte length 12AE Structure: 1 (0x01) - 12AF Version: 1 (0x01) 12B0 Item Designator: 13 (0x0D) - User Organisation Registered For Public Use 12B1 Organization: 1 (0x01) - AAF 12B2 Application: 1 (0x01) - Structural Metadata Sets 12B3 Structure Version: 1 (0x01) - Version 1 12B4 Structure Kind: 1 (0x01) - MXF / AAF Association compatible sets & packs 12B5 Set Kind (1): 1 (0x01) 12B6 Set Kind (2): 40 (0x28) 12B7 Reserved: 0 (0x00) 12B8 Length: 131 (0x83) 12B9 Length: 292 (0x000124)
It is the CDCI descriptor UL, it should be the RGBA descriptor label (byte at 12B6 should be 0x29).
1350 Horizontal colour subsampling - 1 (0x1) (8 bytes) 1350 Header (4 bytes) 1350 Code: 13058 (0x3302) 1352 Length: 4 (0x0004) 1354 Data: 1 (0x00000001) 1358 Vertical colour subsampling - 1 (0x1) (8 bytes) 1358 Header (4 bytes) 1358 Code: 13064 (0x3308) 135A Length: 4 (0x0004) 135C Data: 1 (0x00000001)
Chroma subsampling is not in the source file, it is there (legit but non sense), they should be removed when RGB.
1348 Active bits per sample - 16 (0x10) (8 bytes) 1348 Header (4 bytes) 1348 Code: 13057 (0x3301) 134A Length: 4 (0x0004) 134C Data: 16 (0x00000010)
Bit depth is wrong, even if it is well detected by FFmpeg (indicated as "rgb48 10 bpc"), byte at 134C should be 0x0A.
Initial check of the issue is from https://github.com/MediaArea/MediaInfo/issues/657 .

Replying to Francesco Bucciantini:

I'm having email problems at the moment, so my stop gap hasn't even made it to the list. But yeah RGBADescriptor should be used, not CDCI. Might as well implement all RGB(A) pixel formats while at it.

Do you happen to know what the name of the JPEG2000 MXF wrapping spec is?

(surprisingly it seems free of charge)
Note that the attached file RGBA_example.mxf is from an official IMF evaluation package, and it has good descriptors (essence descriptor with link to jp2k specific descriptor), it also has the J2CLayout ("The nature and order of the image components in the compressed domain as carried in the J2C codestream.") with the RGBALayout (from ST 377) part set to RGB, having the CDCI descriptor replaced by the RGBA descriptor would be a fix of the main issue (catching that this is RGB and not YUV), but having the J2CLayout (or the whole JP2k descriptor) transferred from the input file to the output file would be even better (more compliant to specs, but to be honest RGBALayout is optional so not the biggest problem, RGB can be guessed with RGBA descriptor UL alone and the readout of 3 JP2k components).

Just to add to this to avoid making it go into the list of forgotten items, unfortunately it's not limited to mxf only but also to other containers.
For instance, remuxing to mkv and mov also shows "YUV".
This is particularly problematic if you're gonna use the remuxed file on quite literally anything else other than FFMpeg as plenty of decoders have issues while trying to decode something that claims to be YUV 4:4:4 16bit Limited TV Range and it's actually RGB48 Full Range.

comment:13 by , 3 months ago
Hi Tomas,
thank you for the heads up, but unfortunately the issue is still there. :(
I downloaded and compiled the latest master yesterday, namely N-117613-g72e5381123-20241020.
I then tried to read the CPL of an IMF package and remux the MJPEG2000 in it to an mxf container with the following command:
ffmpeg.exe -f imf -i "G:\mg0\DigitalSupplyChain\WatchfolderMMA\Wacthfolder_UHD\IMF_to_UHD_HLG_AVISYNTH\In\Itendswithus_2024_Th_IT_10977168\CPL_SPE_Itendswithus_11402860_FE_RLI-10977168_CRID-101164127.xml" -map 0:0? -map 0:1? -map 0:2? -map 0:3? -map 0:4? -map 0:5? -map 0:6? -map 0:7? -map 0:8? -c:v copy -c:a copy -f mxf -y "A:\MEDIA\temp\Test.mxf" pause
and unfortunately the error is still there.
In the logs we can see that FFMpeg detects that the source video is indeed RGB48, but it's still writing the CDCI essence descriptor UL instead of the RGBA essence descriptor UL.
This is the full log in FFMpeg:
>ffmpeg.exe -f imf -i "G:\mg0\DigitalSupplyChain\WatchfolderMMA\Wacthfolder_UHD\IMF_to_UHD_HLG_AVISYNTH\In\Itendswithus_2024_Th_IT_10977168\CPL_SPE_Itendswithus_11402860_FE_RLI-10977168_CRID-101164127.xml" -map 0:0? -map 0:1? -map 0:2? -map 0:3? -map 0:4? -map 0:5? -map 0:6? -map 0:7? -map 0:8? -c:v copy -c:a copy -f mxf -y "A:\MEDIA\temp\Test.mxf"
