[FFmpeg-user] 4.6 kernel timeframe?

2016-03-31 Thread Tom Horsley
When is a fedora release likely to have the 4.6 kernel (I suspect fedora 25)? I saw rumors the nvidia maxwell card firmware will finally be included in 4.6 and it might finally be possible to use nouveau with my graphics card, so I'm just wondering when I might be able to stop fooling with nvidia

2016-11-13 Thread Tom Horsley
I have some VP9 files downloaded from youtube that are (in theory) a couple of the new youtube HDR demo files. Can anyone suggest a command line this poor ignorant human can use to convert these to HEVC files, preserving the HDRness? (Apparently VP9 files won't play on my new LG OLED TV, but HEVC

[FFmpeg-user] Speaking of timestamps and audio/video sync issues...
