I have an IMF package with videos and audios and of course the CPL.
Video file is a MJPEG2000 BT709 SDR 10bit muxed in mxf
The audio files are PCM lossless 24bit 48'000Hz muxed as .mxf
To differentiate them, each one has audio tagging inside, so if I use Mediainfo I can see for instance:

As you can see, there's the language tagging:

Language : Italian

same goes for other tracks that might have a different language like English:

so:
Language : English

however when I do:

ffmpeg.exe -f imf -i "D:\Masterfiles\CPL_IMF.xml" -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -c:v copy -c:a copy -f mxf -y "D:\Masterfiles\test.mxf"

pause

FFMpeg outputs an error in the language tagging, namely:

@FranceBB Can you do a dump of the source MXF file at https://registry.smpte-ra.org/apps/regxmldump/view/published/

Done.

It looks like FFmpeg does not support writing MCA sub-descriptors, which contain the language information:

Language seems to be working when converting to MP4: ffmpeg -i WAV_d01bc6be-ae2f-436b-9705-c402e1d92212.mxf out.mp4

The audio track in out.mp4 is labeled "English".

Gotcha, so it's not the IMF code but rather an FFMpeg mxf muxer limitation.
I've created a ticket in the official bug tracker asking for the new feature.
Let's see if someone is gonna pick it up or if it's gonna die out like other mxf related requests... :(

Actually, I'm going to re-open this, 'cause I made some new discoveries.

Decoding the mxf file directly does indeed make the info being displayed in FFMpeg (so I can remux into something else that isn't mxf and supports the language tagging), however such an info ain't displayed when the file is opened by the CPL IMF decoder, thus preventing me from using other containers like mkv etc.

By opening the mxf file directly:

however when I open the CPL with the IMF decoder:

it doesn't display the language tag, so something must be wrong with the IMF / FFMpeg integration.

Again, I don't mean in the final package, I mean inside the FFMpeg decoding.
In other words, it doesn't matter which container I remux to, it will never ever show up.

Do you know how I can trim a IMF package to send you a sample?
The only thing I've been able to trim was the audio file but if I open that directly with -i "file.mxf" it does indeed show (ita), so it's not really a valid test... https://trac.ffmpeg.org/attachment/ticket/9818/trim_1.mxf

Sure, but it's evening in Europe right now.
If you have a build ready I'll try it first thing in the morning tomorrow, otherwise I'll build it tomorrow afternoon as soon as I get a few spare minutes from work.
