OpenGL rendering now requires hardware + that can do at least OpenGL 2.1, the oldest version supported by vo_opengl. +- (!) vf_pp has been removed. A version of it can still be accessed through + lavfilter (e.g. --vf=lavfi=[pp...]), but it receives no QP information. + Also, vf_dlopen no longer passes QP information to its loaded plugin either + (it's always 0). +- (!) vf_pullup, vf_softpulldown, vf_swapuv, vf_phase, vf_divtc and vf_ilpack + have all been removed. Ports or alternative versions of these filters are + available through libavfilter (vf_lavfi). +- (!) ao_portaudio has been removed. There is good support for the native + audio drivers of all major desktop platforms, as well as ao_sdl and + ao_openal as fallbacks. +- (!) vo_opengl's `lscale` suboption has been renamed to `scale`; `lradius` is + now `scale-radius`, `lparam1` and `lparam2` are now respectively + `scale-param1` and `scale-param2`; `lscale-down` is now `scale-down`. + The `cscale` suboption remains as is. +- (!) Several of the `vo_opengl` radius-preset aliases supported by `scale` + have been removed; use `scale-radius` to set if needed. For example, use + `--vo=opengl:scale=lanczos:scale-radius=3` instead of `scale=lanczos3`. +- (!) vo_opengl no longer supports the `stereo` suboption. The anaglyph effect + can be reproduced with the stereo3d filter. The quadbuffer support, which + requires expensive specialized hardware to begin with, is removed. +- (!) The `approx-gama` suboption to vo_opengl has been removed. The BT.1886 + specification says that it's actually how it's supposed to be done so it + is now the default. +- (!) The `no-scale-sep` and `indirect` suboptions to vo_opengl have been + removed. These are now autodetected and enabled whenever they would have + benefit. +- (!) The `--lua` and `--lua-opts` parameters / options are now called + `--script` and `--script-opts`, respectively. The `lua` subdir of the mpv + config dir is also now expected to be called `scripts` instead. +- (!) The `--fixed-vo` option has been removed. It has been the default for + a long time anyway, and disabling fixed-vo is not useful. +- vo_opengl has improved downscaling for higher downscale ratios. +- vo_opengl_hq has been updated to take into account new features. + `fancy-downscaling` and `sigmoid-upscaling` are enabled, + "mitchell" is now the default for `scale-down`, and `scale-down` can be + disabled with `scale-down=""`. +- The `sub-visibility` OSD message is now clearer about whether subtitles + are hidden or just not available / selected. +- The device IDs given to `--audio-device` for use with ao_coreaudio now use + UIDs, so they don't change when devices are added/removed or after reboots. +- `--msg-level` now also accepts ',' as separator. +- (Win32) The embedded .exe description now names itself simply "mpv". +- (Client API) The client API now refuses to initialize if the LC_NUMERIC + locale is not "C". +- (Client API) The native type of the `msg-level` parameter is now a key-value + list. Setting or reading it as a string still works. +- Documentation updates. +- PDF documentation is now disabled by default due to rst2pdf being fickle, + causing weird build errors. +- Print desync messages with negative A/V sync as well. While rare, it could + happen ith some uses of `--autosync`. + +Bug fixes +--------- + +- (Windows) Avoid resizing the video window when player is minimized, might + address bug #1547. +- (NetBSD) Fix build with v4l2. +- Multiple cdda:// fixes. (bugs #1555, #1560) + +New features +------------ + +- vo_opengl now supports frame blending to eliminate stuttering when the video + framerate does not nicely match the display framerate through the + `smoothmotion` suboption. This is not meant to artificially increase the + video's FPS, so there is no "soap opera effect" or difficulties with some + video types (e.g. anime). +- vo_opengl now supports sigmoidal upscaling (e.g. for fullscreen), which + reduces ringing induced by upscaling, enabled through the `sigmoid-upscaling` + suboption. +- vo_opengl's ewa_lanczos scaler (Jinc) now supports an `scale-antiringing` + parameter, which tries to reduce video ringing. +- vo_opengl now has a `linear-scaling` suboption, that makes the scalers work + in linear light. Implied by the `srgb`, `icc-profile` or the new + `sigmoid-upscaling` suboption. +- The Matroska demuxer now supports SVQ3 video. +- Add `--keep-open=always` to make `--keep-open` apply to all files instead of + only the last. +- mpv now filters the tags that are printed on the console to try to hide + useless metadata. The filter works as a whitelist, and can be configured with + the `--display-tags` option. +- Add a `--sub-scale-by-window` option that, when set to 'no', prevents + subtitles from changing their pixel size when the window changes sizes. +- vo_opengl now technically has GLES 2 and 3 support (but not GLES 1). GLES 3 + support is only tested on Mesa's software emulation. GLES 2 has been tested + on nvidia drivers, but is feature deficient and inefficient due to GLES 2 + limitations. +- (X11) vo_opengl now supports the `icc-profile-auto` option on X11 hosts. +- The 'A' key now by default cycles through a list of preset aspect ratios. + Meant to be used to work around broken files. +- There is now a `--log-file` option to write mpv's log messages to a specifed + file. +- There is now a `--audio-file-auto` option to automatically load an external + audio file with certain constraints. Will only load external audio if the + playing file has a video stream. Set to "exact" by default. (bug #967) +- VP9 timestamps are now supported with new enough FFmpeg builds. +- There is now a `--network-timeout` option to specify a timeout in seconds for + network access. If 0 (default), uses the libavformat default. If a protocol + that doesn't support timeouts is used, this option is ignored. +- (Linux) The DVB implementation now supports DVB-S2 through S2API. +- (Client API) There is now an opengl_cb VO, which receives the OpenGL context + from the libmpv client. This allows a client to render libmpv video directly + to a provided OpenGL context without having to use hacks such as --wid. +- (Client API) The aforementioned --wid hack can now be set at any time, but + has no effect if a file is already loaded. +- (Client API) The list of DVD titles can now be queried. +- (Client API) There is now a `filtered-metadata` property, containing only + the tags allowed by `--display-tags`. +- (Client API) There is now support for XEmbed `--wid` targets, such as a + `GtkSocket`'s `gtk_socket_get_id()`. +- (Client API) There is now a `file-format` property with a symbolic name + for the file format. In some cases this might be a comma separated list + of various different extensions due to libavformat idiosyncrasies. +- (Client API) There is now a `mouse` command for generating mouse events + over the video window. +- (Client API) There is now a `partially-seekable` property that indicates + whether a file is only considered `seekable` because of the stream cache, + but would not be seekable otherwise (e.g. realtime stream, or HTTP with + no resume support). Small relative seeks may be fine, but larger seeks + will likely fail. +- (Client API) There is now an MPV_EVENT_QUEUE_OVERFLOW event that is posted + whenever events have to be dropped because the queue is full. No further + events are posted until the MPV_EVENT_QUEUE_OVERFLOW is consumed to avoid + duplicated posting. +- (Client API) There is now a helper `mpv_wait_async_requests()` function + that blocks until all known async requests have completed. (bug #1542) +- (Client API) There is now a `detected-hwdec` property that returns the + detected hardware decoder when one is successfully opened. This probably + only returns a valid value after playback has started. +- (Client API) There are now `audio_add`, `audio_remove` and `audio_reload` + counterparts to the equivalent `sub_` commands for handling external audio + files. + + +This listing is not complete. A complete changelog can be seen by running +`git log v0.7.0..` in the git repository. +
