  • 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,

    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.













  • It’s all reasonable stuff except maybe:

    People’s names are all mapped in Unicode code points.

    I don’t see how you could avoid this this in software that needs to ask the user their name.

    I think it’s definitely a good idea to avoid using names wherever possible, and definitely don’t try to do anything clever with them.

    When necessary, software can just be clear:

    • “in unicode, what should I call you?”
    • "in unicode, who is making this credit card transaction?’






  • It’s a totally valid approach. Most of the answers in this thread involve booting some non windows thing, and running a tool that will do exactly this behind the scenes.

    Edit: there are also a lot of much more terrible answers that involve file-level copying that will definitely not work.
