#10341 ([Intel Caption] Microsoft RTMP Ingest - FFmpeg fails to decode closed-caption to srt/webvtt) – FFmpeg
trac.ffmpeg.org

Microsoft employee:

Hi, This is a high priority ticket and the FFmpeg version is currently used in a highly visible product in Microsoft. We have customers experience issues with Caption during Teams Live Event. Please help

Maintainer’s comment on twitter:

After politely requesting a support contract from Microsoft for long term maintenance, they offered a one-time payment of a few thousand dollars instead.

This is unacceptable.

And further:

The lesson from the xz fiasco is that investments in maintenance and sustainability are unsexy and probably won’t get a middle manager their promotion but pay off a thousandfold over many years.

But try selling that to a bean counter

    This seems like a “you” problem, Microsoft, and since you employ thousands of programmers with the experience to solve your problem and commit the change back to the FOSS project, I think this is also very easily a “you” solution as well.

    It’s so ridiculous that this isn’t even brought up:

    The Command you provided worked fine. Thank you so much for the help! Really appreciated! We are going to proceed to make a release today and test with customers. Will post the updates here.

    Gotta love being a forced beta tester… I mean customer.

    Use -data_field first as decoder option in CLI. Default value was changed from first to auto in latest FFmpeg version. Or modify AVOption of same name in API for this decoder.

    Thanks @Elon for the reply, This is the command we are currently using: ffmpeg.exe -f lavfi -i movie=flvdecoder_input223.flv[out+subcc] -y -map 0:1 ./output_p.srt

    I will be looking to see any updates in the FFmpeg documentation. Can you please elaborate and provide pointers the right decoding options or the right FF command er can use. Thank you!

    ffmpeg.exe -data_field first -f lavfi -i movie=flvdecoder_input223.flv[out+subcc] -y -map 0:1 ./output_p.srt

    Got that’s fucking brutal. This isn’t even asking them to fix a bug, it’s just basic help-desk shit.

    I’m sure Microsoft has some good devs that are a net benefit to the open source projects they use, but this is not one of them.
