Microsoft opens a "high priority" bug ticket in ffmpeg, attempting to leech the free labour of the maintainers (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

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.

You got this dumbass at MS and then you've got the other MS guy who's a god damn hero that very well might have saved the world atm lmao

Jon Skeet? He’s my hero, but he hasn’t worked at MS for quite some time I believe.

He’s talking about Andres Freund, who uncovered the OpenSSL backdoor that was slipped into liblzma from the xz malicious maintainer. Dude saw a valgrind error and a function with a fixed runtime was taking too long and using too much CPU and reversed out and saved a major ssh backdoor from going upstream as Fedora was going to release it just days later.
