[00:48:14 CEST] <TheAverageKappa> HEy
[00:49:09 CEST] <TheAverageKappa> Hey guys, I'm trying to use m:key[:value] to match specific stream types
[00:49:26 CEST] <TheAverageKappa> Specifically, I'm trying to remove subtitles with the type hdmv_pgs_subtitle
[00:49:42 CEST] <TheAverageKappa> What's the key for 'stream type'?
[01:03:21 CEST] <c_14> I think you can only use things ffprobe lists with TAG:, codec_name isn't one of those
[01:03:45 CEST] <c_14> what you can do though is output ffprobe to csv or json, parse that in a script and then call ffmpeg with the information
[06:21:55 CEST] <ZeroWalker> probably asked this before, been searching but can't find it so, yeah. does ffmpeg have a way to cut out a part of a video, and re-encode if it needs to cause of keyframe misses?
[07:29:03 CEST] <loosechainsaw> when using cuda for hardware acceleration is the output pixel format always NV12?
[07:32:10 CEST] <loosechainsaw> using ffmpeg in code for mjpeg and not getting any joy when copying out of avframe data[0] and data[1] to another cuda buffer
[07:32:35 CEST] <loosechainsaw> thought the output would be nv12 so my existing cuda kernel function should continue to work
