Wenn mir #mpv eine "Colormatrix: dolbyvision" anzeigt, bei nem Video, das keinen TrueHD- oder EAC3-Track hat, sondern FLAC, was bedeutet das dann? Hat das Video #DolbyVision-Informationen eingebettet oder nicht? Vielleicht nur einen Teil davon? Wie geht das überhaupt, ich dachte, diese Metainformationen wären immer im proprietären Dolby-Track?

Unter "Format" steht "p010" was Dolby Vision Profile 8.4 entspricht, einem irgendwie zu HLG kompatiblem Encoding, hä? Aber wo wird das nun hinterlegt?

A first experiment in #gstreamer is quite promising - on the x220 it already makes Showtime (the future Gnome default player) outperform #mpv with 4k@30fps AV1 or VP9 playback - my hope is to get 4k@60fps work smoothly (SDR - bonus for HDR10, but the required shaders might end up being too heavy).

For those interested, you can find the code at gitlab.freedesktop.org/gstream
