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
FFMPEG is a core technology. You literally cannot do anything with video without touching FFMPEG at multiple places in the stack.
The fact that we have billions of dollars of revenue flowing through that software every day, but we rely on VOLUNTEERS to maintain it shows exactly how hollow the whole SV entrepreneur culture really is.
Bunch of fucking posers wouldn’t know performance code if it kicked them in the face.
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.
If the live version is already broken, there isn’t much to lose deploying the fix as soon as possible. Not sure what else they could have done here.
Yup. Shits fucked. Do what you can. Lol
isn’t that what a canary release essentially is?

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.
This is pretty funny, kinda suggests they have no faith in the engineers they work with… ffmpeg is an awesome piece of work, but if it’s a bug they can repeat to some level, then like you said, it 100% a them problem!
E: oh, was thinking it was a pm raised it, but seems it was possibly one of their developers, brutal…

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.

Tell Copilot to fix it.
Can’t reproduce bug. Closing ticket.
It’s what Microsoft would do in the same situation. It’s only fair
I understand you are having a problem with ffmpeg.
Firstly, I will need you to open a command prompt and run SFC /scannow.
And then reboot your PC.
And then run SFC /scannow again.
And reboot again.
Until you give up and reinstall Windows.
