Both Andrea and I tested the patch with Andrea's notes in BT #677. I also get bad results and am still looking for a workaround other than using a 2025 older AppImage prior to 8.0 - right now we are at FFmpeg 8.1 and I would like to at least check 8.0 to see how that works.
Strange. On termux without audio and with Terje's HDV short clip as input (1440*1080, interlaced) I do not see "patch welcome" messages with my patch and dynamic ffmpeg libs 8.1.2 Can you test 1) without audio 2) with different input files? and if possible with dynamic ffmpeg 8.1.2 ?

Can you check if this patch fixes mxf profiles, while still leaving our language info etc in ts and other formats?

Andrew, I will also try to figure out what the cause is using gdb.
I tried to set breakpoint ("b" command in gdb ) to
avformat_write_header
but because Termux libavformat stripped from symbols for size reasons
single stepping ("s" command) just returned me to our function with already-set error code.
if I skip this error checking and go ahead libavformat segfaults kater on openjpeg/DNxHR at least (mxf openjpeg profile need change of encoder from libopenjpeg to jpeg2000 - libopenjpeg encoder was removed If I remember correctly some time ago from ffmpeg).

See https://bug.cinelerra-gg.org/view.php?id=677 for problem and workaround to use an old 2025 AppImage. Root cause appears to me to be unimplemented patch - at least by February 2026 version of FFmpeg 8.1 - and hoping Andrew-R can check to see if by now there is a patch. Details in Mantis Bug Tracker of testing done.
Yes, I am looking into it
So far using termux's shared ffmpeg 8.1.2 libs I hit same error.
Not really obvious what causes it - avformat_wrie_header returns error, but there is no muxer-specific mxf write_header function in libavformat/mxfenc.c ?
