mpv 0.27版本更新 Linux和OSX中高質素播放器

MPV是Linux系統發展起來建基於mplayer2和MPlayer的播放器，近乎無任何元件既極簡潔介面成為佢既特色之一，另外支援OpenGL既高質素影像輸出，令MPV成為Linux同OSX(mac os)中一個代表高畫質既播放器。

MPV player亦支援多種檔案格式mp4、mkv、avi、ts等；多種影像壓格式x264/avc、x265/hevc、vp9、xvid等；不同音訊格式mp3、aac、flac等，所以支援極多影片或聲音檔案。
在windows是mpc-hc、mpc-be、potplayer以外的選擇，在linux/OSX是vlc、smplayer之外的選項。

更新內容


本次更新不像0.26增加HDR的重大功能，不過修正增加此功能之後產生的問題，亦修正其他問題。

v0.27.0

Features
Added
Windows: handle media keys
libmpv: options: add a thread-safe way to notify option updates
vd_lavc/vo_opengl: support embedded ICC profiles
vo: rendering API abstraction for future non-GL video outputs
vo_opengl: add a gamut warning feature to highlight out-of-gamut colors (--gamut-warning)
vo_opengl: add direct rendering support (--vd-lavc-dr)
vo_opengl: implement (faster) compute shader based EWA kernel
vo_opengl: implement HLG OOTF inverse
vo_opengl: support HDR peak detection (--hdr-compute-peak)
vo_opengl: support float input pixel formats
vo_opengl: support loading custom user textures (#4586)
vo_opengl: support user compute shaders
Removed
Remove video equalizer handling from vo_direct3d, vo_sdl, vo_vaapi, and vo_xv (GPL, not worth the effort to support legacy VOs)
Options and Commands
Added
macOS: add --no-native-fs option to disable the native macOS fullscreen (#4014)
player: add --track-auto-selection option
Changed
input: use mnemonic names for mouse buttons, same as Qt: https://doc.qt.io/qt-5/qt.html#MouseButton-enum
options: change --loop semantics
player: make --lavfi-complex changeable at runtime
vf_eq: remove this filter (GPL; uses libavfilter’s eq filter now, with changed semantics)
video: change --deinterlace behavior
vo_opengl: generalize HDR tone mapping to gamut mapping, --hdr-tone-mapping → --tone-mapping
Removed
--field-dominance (GPL-only author, no chance of relicensing)
input: drop deprecated "osd" command
options: drop --video-aspect-method=hybrid (GPL-only)

vf_vapoursynth: fix inverted sign and restore 10 bit support (#4720)
video: increase --monitorpixelaspect range
vo_opengl: adjust the rules for linearization (#4631)
vo_opengl: scale deband-grain to the signal range
vo_opengl: tone map on the maximum signal component
x11: fix that window could be resized when using embedding (#4784)
ytdl_hook: resolve relative paths when joining segment urls (#4827)
ytdl_hook: support fragments with relative paths, fixes segmented DASH
