* DOCS/compatibility.rst: add this filewm42019-10-051-0/+5
| | | | | | | | | | | Another thing nobody will read. I'm attempting to document the rules by which incompatible changes can be made. These rules have always been present in this project, but I don't think they were written down. Or maybe they were, but I forgot where. I think due to the time of the day it became increasingly incoherent (not necessarily near the end of the text). Hopefully no logical or freudian lapses in there.
* DOCS/interface-changes.rst: simplify playback abort change descriptionwm42019-10-051-11/+2
| | | | | | | | | | | Although it was not true at the time this was written, both the "program" and "cache-size" are gone now. Since the changelog is for the entire next release, it makes no sense to mention these removed properties. It also happens to make the description of this much simpler, because it's a non-issue now. It's probably not even worth mentioning anymore.
* options: rename --video-aspect to --video-aspect-overrideNiklas Haas2019-10-041-0/+2
| | | | | | | | | | | | The justification for this is the fact that the `video-aspect` property doesn't work well with `cycle_values` commands that include the value "-1". The "video-aspect" property has effectively no change in behavior, but we may want to make it read-only in the future. I think it's probably fine to leave as-is, though. Fixes #6068.

* options: remove --chapterwm42019-09-191-0/+1
| | | | | | | | | Has been deprecated for almost 3 years. Manpage didn't mention the deprecation, but CLI and release notes did. It wouldn't be much effort to keep this option working, but I just don't see the damn point. --start/--end can specify chapters using special syntax, which is equivalent.
* vo_gpu: x11: remove special vdpau probing, use EGL by defaultwm42019-09-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, vo_gpu/vo_opengl considered the case of Nvidia proprietary drivers, which required vdpau/GLX, and Intel open source drivers, which require vaapi/EGL. Since window creation and GPU context creation are inseparable in mpv's internal API, it had to pick the correct API very early, or hardware decoding wouldn't work. "x11probe" was introduced for this reason. It created a GLX context (without showing the window yet), and checked whether vdpau was available. If yes, it used GLX, if not, it continued probing x11/EGL. (Obviously it couldn't always fail on GLX without vdpau, which is why it was a separate "probe" backend.) Years passed, and now the situation is different. Vdpau is dead. Nvidia drivers and libavcodec now provide CUDA interop, which requires EGL, and fixes some of the vdpau problems. AMD drivers now provide vaapi, which generally works better than vdpau. Intel didn't change. In particular, vaapi provides working HEVC Main10 support. In theory, it should work on vdpau too, with quality reduction (no 10 bit surfaces), but I couldn't get it to work. So always prefer EGL. And suddenly hardware decoding works. This is actually rather important, because HEVC is unfortunately on the rise, despite shitty encoders and unoptimized decoders. The latter may mean that hardware decoding works better than libavcodec. This should have been done a long, long time ago.
* command, demux: remove program propertywm42019-09-131-0/+1
| | | | | | | | | The "program" property could switch between TS programs. It was rather complex and rather obscure (even if you deal with TS captures, you usually don't need it). If anyone actually needs it (did anyone ever attempt to even use it?), it should be rewritten. The demuxer should export a program list, and the frontend should handle the "cycling" logic.
* Remove classic Linux analog TV support, and DVB runtime controlswm42019-09-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Linux analog TV support (via tv://) was excessively complex, and whenever I attempted to use it (cameras or loopback devices), it didn't work well, or would have required some major work to update it. It's very much stuck in the analog past (my favorite are the frequency tables in frequencies.c for analog TV channels which don't exist anymore). Especially cameras and such work fine with libavdevice and better than tv://, for example: mpv av://v4l2:/dev/video0 (adding --profile=low-latency --untimed even makes it mostly realtime) Adding a new input layer that targets such "modern" uses would be acceptable, if anyone is interested in it. The old TV code is just too focused on actual analog TV. DVB is rather obscure, but has an active maintainer, so don't remove it. However, the demux/stream ctrl layer must go, so remove controls for channel switching. Most of these could be reimplemented by using the normal method for option runtime changes.
* Remove optical disc fancification layerswm42019-09-131-0/+2
| | | | | | | | | | | | | | | | | This removes anything related to DVD/BD/CD that negatively affected the core code. It includes trying to rewrite timestamps (since DVDs and Blurays do not set packet stream timestamps to playback time, and can even have resets mid-stream), export of chapters, stream languages, export of title/track lists, and all that. Only basic seeking is supported. It is very much possible that seeking completely fails on some discs (on some parts of the timeline), because timestamp rewriting was removed. Note that I don't give a shit about optical media. If you want to watch them, rip them. Keeping some bare support for DVD/BD is the most I'm going to do to appease the type of lazy, obnoxious users who will care. There are other players which are better at optical discs.

* cocoa-cb: refactor title bar stylingder richter2019-04-021-0/+2
| | | | | | | | | | | | | half of the materials we used were deprecated with macOS 10.14, broken and not supported by run time changes of the macOS theme. furthermore our styling names were completely inconsistent with the actually look since macOS 10.14, eg ultradark got a lot brighter and couldn't be considered ultradark anymore. i decided to drop the old option --macos-title-bar-style and rework the whole mechanism to allow more freedom. now materials and appearance can be set separately. even if apple changes the look or semantics in the future the new options can be easily adapted.

| * vo_gpu: allow boosting dark scenes when tone mappingNiklas Haas2019-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | In theory our "eye adaptation" algorithm works in both ways, both darkening bright scenes and brightening dark scenes. But I've always just prevented the latter with a hard clamp, since I wanted to avoid blowing up dark scenes into looking funny (and full of noise). But allowing a tiny bit of over-exposure might be a good thing. I won't change the default just yet (better let users test), but a moderate value of 1.2 might be better than the current 1.0 limit. Needs testing especially on dark scenes.
| * vo_gpu: redesign peak detection algorithmNiklas Haas2019-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous approach of using an FIR with tunable hard threshold for scene changes had several problems: - the FIR involved annoying hard-coded buffer sizes, high VRAM usage, and the FIR sum was prone to numerical overflow which limited the number of frames we could average over. We also totally redesign the scene change detection. - the hard scene change detection was prone to both false positives and false negatives, each with their own (annoying) issues. Scrap this entirely and switch to a dual approach of using a simple single-pole IIR low pass filter to smooth out noise, while using a softer scene change curve (with tunable low and high thresholds), based on `smoothstep`. The IIR filter is extremely simple in its implementation and has an arbitrarily user-tunable cutoff frequency, while the smoothstep-based scene change curve provides a good, tunable tradeoff between adaptation speed and stability - without exhibiting either of the traditional issues associated with the hard cutoff. Another way to think about the new options is that the "low threshold" provides a margin of error within which we don't care about small fluctuations in the scene (which will therefore be smoothed out by the IIR filter).
| * vo_gpu: improve tone mapping desaturationNiklas Haas2019-02-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of desaturating towards luma, we desaturate towards the per-channel tone mapped version. This essentially proves a smooth roll-off towards the "hollywood"-style (non-chromatic) tone mapping algorithm, which works better for bright content, while continuing to use the "linear" style (chromatic) tone mapping algorithm for primarily in-gamut content. We also split up the desaturation algorithm into strength and exponent, which allows users to use less aggressive desaturation settings without affecting the overall curve.

| * player: make playback termination asynchronouswm42018-05-241-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, stopping playback aborted the demuxer and I/O layer violently by signaling mp_cancel (bound to libavformat's AVIOInterruptCB mechanism). Change it to try closing them gracefully. The main purpose is to silence those libavformat errors that happen when you request termination. Most of libavformat barely cares about the termination mechanism (AVIOInterruptCB), and essentially it's like the network connection is abruptly severed, or file I/O suddenly returns I/O errors. There were issues with dumb TLS warnings, parsers complaining about incomplete data, and some special protocols that require server communication to gracefully disconnect. We still want to abort it forcefully if it refuses to terminate on its own, so a timeout is required. Users can set the timeout to 0, which should give them the old behavior. This also removes the old mechanism that treats certain commands (like "quit") specially, and tries to terminate the demuxers even if the core is currently frozen. This is for situations where the core synchronized to the demuxer or stream layer while network is unresponsive. This in turn can only happen due to the "program" or "cache-size" properties in the current code (see one of the previous commits). Also, the old mechanism doesn't fit particularly well with the new one. We wouldn't want to abort playback immediately on a "quit" command - the new code is all about giving it a chance to end it gracefully. We'd need some sort of watchdog thread or something equally complicated to handle this. So just remove it. The change in osd.c is to prevent that it clears the status line while waiting for termination. The normal status line code doesn't output anything useful at this point, and the code path taken clears it, both of which is an annoying behavior change, so just let it show the old one.
| * player: simplify edition switchingwm42018-05-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The player fully restarts playback when the edition or disk title is changed. Before this, the player tried to reinitialized playback partially. For example, it did not print a new "Playing: <file>" message, and did not send playback end to libmpv users (scripts or applications). This playback restart code was a bit messy and could have unforeseen interactions with various state. There have been bugs before. Since it's a mostly cosmetic thing for an obscure feature, just change it to a full restart. This works well, though since it may have consequences for scripts or client API users, mention it in interface-changes.rst.
| * command: give named arguments to almost all commandswm42018-05-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this change, only 1 command or so had named arguments. There is no reason why other commands can't have them, except that it's a bit of work to add them. Commands with variable number of arguments are inherently incompatible to named arguments, such as the "run" command. They still have dummy names, but obviously you can't assign multiple values to a single named argument (unless the argument has an array type, which would be something different). For now, disallow using named argument APIs with these commands. This might change later. 2 commands are adjusted to not need a separate default value by changing flag constants. (The numeric values are C only and can't be set by users.) Make the command syntax in the manpage more consistent. Now none of the allowed choice/flag names are in the command header, and all arguments are shown with their proper name and quoted with <...>. Some places in the manpage and the client.h doxygen are updated to reflect that most commands support named arguments. In addition, try to improve the documentation of the syntax and need for escaping etc. as well. (Or actually most uses of the word "argument" should be "parameter".)
| * ipc: some user-visible changes to prepare for making all commands asyncwm42018-05-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I wanted to put all commands through mpv_command_node_async() instead of mpv_command_node(). Using synchronous commands over a synchronous transport doesn't make sense anyway. This would have used the request_id field in IPC requests as reply ID for the async commands. But the latter need to be [u]int64, while the former can be any type. To avoid that we need an extra lookup table for mapping reply IDs to request_id values, we now require that request_id fields are integers. Since this would be an incompatible change, just deprecate non-integers for now, and plan the change for a later time.
* | spirv: remove --spirv-compiler=nvidiaNiklas Haas2018-12-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This option has been deprecated upstream for a long time, probably doesn't even work anymore, and won't work moving forwards as we replace the vulkan code by libplacebo wrappers. I haven't removed the option completely yet since in theory we could still add support for e.g. a native glslang wrapper in the future. But most likely the future of this code is deletion. As an aside, fix an issue where the man page didn't mention d3d11.
* | drm: rename plane options to better, invariant, namesAnton Kindestam2018-12-011-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit bumps the libmpv version to 1.102 drm-osd-plane -> drm-draw-plane drm-video-plane -> drm-drmprime-video-plane drm-osd-size -> drm-draw-surface-size "draw plane", as in the plane that OpenGL draws to, whether it be video + OSD or just OSD. "drmprime video plane", as in the plane used for hwdec video imported via drmprime. "draw surface size", as in the size of the surface used for the draw plane The new names are invariant whether or not hwdec_drmprime_drm is being used or not. The original naming was very confusing, as when doing regular rendering (swdec or vaapi) the video would be displayed on the "OSD plane", and the "Video plane" would remain unused.
* | drm_atomic: Add general primary/overlay plane optionAnton Kindestam2018-12-011-0/+5
| | | | | | | | | | | | | | | | | | | | Add general primary/overlay plane option to drm-osd-plane-id and drm-video-plane-id, so that the user can just request any usable primary or overlay plane for either of these two options. This should be somewhat more user-friendly (especially as neither of these two options currently have a useful help function), as usually you would only be interested in the type of the plane, and not exactly which plane gets picked.
* | vo_gpu: split --linear-scaling into two separate optionsNiklas Haas2018-10-191-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since linear downscaling makes sense to handle independently from linear/sigmoid upscaling, we split this option up. Now, linear-downscaling is its own option that only controls linearization when downscaling and nothing more. Likewise, linear-upscaling / sigmoid-upscaling are two mutually exclusive options (the latter overriding the former) that apply only to upscaling and no longer implicitly enable linear light downscaling as well. The old behavior was very confusing, as evidenced by issues such as #6213. The current behavior should make much more sense, and only minimally breaks backwards compatibility (since using linear-scaling directly was very uncommon - most users got this for free as part of gpu-hq and relied only on that). Closes #6213.

* command: change cycle-value command behaviorwm42018-04-291-0/+2
| | | | | | | | | | | | | | | | | | | | Instead of using an internal counter to keep track of the value that was set last, attempt to find the current value of the property/option in the value list, and then set the next value in the list. There are some potential problems. If a property refuses to accept a specific value, the cycle-values command will fail, and start from the same position again. It can't know that it's supposed to skip the next value. The same can happen to properties which behave "strangely", such as the "aspect" property, which will return the current aspect if you write "-1" to it. As a consequence, cycle-values can appear to get "stuck". I still think the new behavior is what users expect more, and which is generally more useful. We won't restore the ability to get the old behavior, unless we decide to revert this commit entirely. Fixes #5772, and hopefully other complaints.

* scripting: change when/how player waits for scripts being loadedwm42018-04-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fundamentally, scripts are loaded asynchronously, but as a feature, there was code to wait until a script is loaded (for a certain arbitrary definition of "loaded"). This was done in scripting.c with the wait_loaded() function. This called mp_idle(), and since there are commands to load/unload scripts, it meant the player core loop could be entered recursively. I think this is a major complication and has some problems. For example, if you had a script that does 'os.execute("sleep inf")', then every time you ran a command to load an instance of the script would add a new stack frame of mp_idle(). This would lead to some sort of reentrancy horror that is hard to debug. Also misc/dispatch.c contains a somewhat tricky mess to support such recur
