build: make LGPL mode final (via --enable-gpl) Rename --enable-preliminary-lgpl2 to --enable-gpl. This concludes the relicensing. Some things are still to do (relicensing some still-GPL optional code), but we consider the code included by --enable-gpl to be fully relicensed. The relicensing was performed by asking every known author for permission for relicensing it to LGPL version 2.1 "or later". If an author could not be contacted or permission could not be obtained, and the contribution was considered relevant for copyright purposes, the affected code was either excluded from LGPL mode (not built), or removed or rewritten. This is the standard in open source relicensing processes. Keep in mind that using LGPL mode is still on the user's own risk. Even though I claim that the relicensing was pretty clean and thorough (measured on the standards of the open source community¹), and I followed the advice of some actual experts, there is still a residual uncertainty due to the fact that I'm not an all-knowing entity (authors could have taken someone else's code and pretend it's their own) nor a lawyer (meaning I might lack associated authority or expertise), and the fact that the judicial system is far from deterministic. The relicensing was performed merely to the best of my knowledge. I reject all responsibility outside of that. This commit also cleans up the "Copyright" file to reflect the finalized relicensing process. ¹ Not to imply that the standards of commercial companies are much higher. Some major tech companies get away with stuff I would not consider clean. See #2033.

lua: add an utility function for starting processes Because 1) Lua is terrible, and 2) popen() is terrible. Unfortunately, since Unix is also terrible, this turned out more complicated than I hoped. As a consequence and to avoid that this code has to be maintained forever, add a disclaimer that any function in Lua's utils module can disappear any time. The complexity seems a bit ridiculous, especially for a feature so far removed from actual video playback, so if it turns out that we don't really need this function, it will be dropped again. The motivation for this commit is the same as with 8e4fa5fc. Note that there is an "#ifndef __GLIBC__". The GNU people are very special people and thought it'd be convenient to actually declare "environ", even though the POSIX people, which are also very special people, state that no header declares this and that the user has to declare this manually. Since the GNU people overtook the Unix world with their very clever "embrace, extend, extinguish" strategy, but not 100%, and trying to build without _GNU_SOURCE is hopeless; but since there might be Unix environments which support _GNU_SOURCE features partially, this means that in practice "environ" will be randomly declared or not declared by system headers. Also, gcc was written by very clever people too, and prints a warning if an external variable is declared twice (I didn't check, but I suppose redeclaring is legal C, and not even the gcc people are clever enough to only warn against a definitely not legal C construct, although sometimes they do this), ...and since we at mpv hate compiler warnings, we seek to silence them all. Adding a configure test just for a warning seems too radical, so we special-case this against __GLIBC__, which is hopefully not defined on other libcs, especially not libcs which don't implement all aspects of _GNU_SOURCE, and redefine "environ" on systems even if the headers define it already (because they support _GNU_SOURCE - as I mentioned before, the clever GNU people wrote software THAT portable that other libcs just gave up and implemented parts of _GNU_SOURCE, although probably not all), which means that compiling mpv will print a warning about "environ" being redefined, but at least this won't happen on my system, so all is fine. However, should someone complain about this warning, I will force whoever complained about this warning to read this ENTIRE commit message, and if possible, will also force them to eat a printed-out copy of the GNU Manifesto, and if that is not enough, maybe this person could even be forced to convince the very clever POSIX people of not doing crap like this: having the user to manually declare somewhat central symbols - but I doubt it's possible, because the POSIX people are too far gone and only care about maintaining compatibility with old versions of AIX and HP-UX. Oh, also, this code contains some subtle and obvious issues, but writing about this is not fun.

vo_opengl: add DRM EGL backend Notes: - Unfortunately the only way to talk to EGL from within DRM I could find involves linking with GBM (generic buffer management for Mesa.) Because of this, I'm pretty sure it won't work with proprietary NVidia drivers, but then again, last time I checked NVidia didn't offer proper screen resolution for VT. - VT switching doesn't seem to work at all. It's worth mentioning that using vo_drm before introduction of VT switcher had an anomaly where user could switch to another VT and input text to it, while video played on top of that VT. However, that isn't the case with drm_egl: I can't switch to other VT during playback like this. This makes me think that it's either a limitation coming from my firmware or from EGL/KMS itself rather than a bug with my code. Nonetheless, I still left (untestable) VT switching code in place, in case it's useful to someone else. - The mode_id, connector_id and device_path should be configurable for power users and people who wish to watch videos on nonprimary screen. Unfortunately I didn't see anything that would allow OpenGL backends to register their own set of options. At the same time, adding them to global namespace is pointless. - A few dozens of lines could be shared with vo_drm (setting up VT switching, most of code behind page flipping). I don't have any strong opinion on this. - Sometimes I get minor visual glitches. I'm not sure if there's a race condition of some sort, unitialized variable (doubtful), or if it's buggy driver. (I'm using integrated Intel HD Graphics 4400 with Mesa) - .config and .control are very minimal. Signed-off-by: wm4 <wm4@nowhere>

vo_gpu: d3d11: initial implementation This is a new RA/vo_gpu backend that uses Direct3D 11. The GLSL generated by vo_gpu is cross-compiled to HLSL with SPIRV-Cross. What works: - All of mpv's internal shaders should work, including compute shaders. - Some external shaders have been tested and work, including RAVU and adaptive-sharpen. - Non-dumb mode works, even on very old hardware. Most features work at feature level 9_3 and all features work at feature level 10_0. Some features also work at feature level 9_1 and 9_2, but without high-bit- depth FBOs, it's not very useful. (Hardware this old is probably not fast enough for advanced features anyway.) Note: This is more compatible than ANGLE, which requires 9_3 to work at all (GLES 2.0,) and 10_1 for non-dumb-mode (GLES 3.0.) - Hardware decoding with D3D11VA, including decoding of 10-bit formats without truncation to 8-bit. What doesn't work / can be improved: - PBO upload and direct rendering does not work yet. Direct rendering requires persistent-mapped PBOs because the decoder needs to be able to read data from images that have already been decoded and uploaded. Unfortunately, it seems like persistent-mapped PBOs are fundamentally incompatible with D3D11, which requires all resources to use driver- managed memory and requires memory to be unmapped (and hence pointers to be invalidated) when a resource is used in a draw or copy operation. However it might be possible to use D3D11's limited multithreading capabilities to emulate some features of PBOs, like asynchronous texture uploading. - The blit() and clear() operations don't have equivalents in the D3D11 API that handle all cases, so in most cases, they have to be emulated with a shader. This is currently done inside ra_d3d11, but ideally it would be done in generic code, so it can take advantage of mpv's shader generation utilities. - SPIRV-Cross is used through a NIH C-compatible wrapper library, since it does not expose a C interface itself. The library is available here: https://github.com/rossy/crossc - The D3D11 context could be made to support more modern DXGI features in future. For example, it should be possible to add support for high-bit-depth and HDR output with DXGI 1.5/1.6.

RPI support This requires FFmpeg git master for accelerated hardware decoding. Keep in mind that FFmpeg must be compiled with --enable-mmal. Libav will also work. Most things work. Screenshots don't work with accelerated/opaque decoding (except using full window screenshot mode). Subtitles are very slow - even simple but huge overlays can cause frame drops. This always uses fullscreen mode. It uses dispmanx and mmal directly, and there are no window managers or anything on this level. vo_opengl also kind of works, but is pretty useless and slow. It can't use opaque hardware decoding (copy back can be used by forcing the option --vd=lavc:h264_mmal). Keep in mind that the dispmanx backend is preferred over the X11 ones in case you're trying on X11; but X11 is even more useless on RPI. This doesn't correctly reject extended h264 profiles and thus doesn't fallback to software decoding. The hw supports only up to the high profile, and will e.g. return garbage for Hi10P video. This sets a precedent of enabling hw decoding by default, but only if RPI support is compiled (which most hopefully it will be disabled on desktop Linux platforms). While it's more or less required to use hw decoding on the weak RPI, it causes more problems than it solves on real platforms (Linux has the Intel GPU problem, OSX still has some cases with broken decoding.) So I can live with this compromise of having different defaults depending on the platform. Raspberry Pi 2 is required. This wasn't tested on the original RPI, though at least decoding itself seems to work (but full playback was not tested).

vo_opengl: add our own copy of OpenGL headers gl_headers.h is basically header_fixes.h done consequently. It contains all OpenGL defines (and some typedefs) we need. We don't include GL headers provided by the system anymore. Some care has to be taken by certain windowing APIs including all of gl.h anyway. Then the definitions could clash. Fortunately, redefining preprocessor symbols to the same content is allowed and ignored. Also, redefining typedefs to the same thing is allowed in C11. Apparently the latter is not allowed in C99, so there is an imperfect attempt to avoid the typedefs if required API symbols are apparently present already. The nost risky part about this are the standard typedefs and GLAPIENTRY. The latter is different only on win32 (and at least consistently so). The typedefs are mostly based on stdint.h typedefs, which khrplatform.h clumsily emulates on platforms which don't have it. The biggest difference is that we define GLsizeiptr directly to ptrdiff_t, instead of checking for the _WIN64 symbol and defining it to long or long long. This also typedefs GLsync to __GLsync, just like the khronos headers. Although symbols prefixed with __ are implementation reserved, khronos also violates this rule, and having the same definition as khronos will avoid problems on duplicate definitions. We can simplify the build scripts too. The ios-gl check seems a bit wrong now (what we really want to test for is EAGLContext), but I can't test and thus can't improve it. cuda_dynamic.h redefined two GL symbols; just include the new headers directly instead.

vo_opengl: refactor into vo_gpu This is done in several steps: 1. refactor MPGLContext -> struct ra_ctx 2. move GL-specific stuff in vo_opengl into opengl/context.c 3. generalize context creation to support other APIs, and add --gpu-api 4. rename all of the --opengl- options that are no longer opengl-specific 5. move all of the stuff from opengl/* that isn't GL-specific into gpu/ (note: opengl/gl_utils.h became opengl/utils.h) 6. rename vo_opengl to vo_gpu 7. to handle window screenshots, the short-term approach was to just add it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to ra itself (and vo_gpu altered to compensate), but this was a stop-gap measure to prevent this commit from getting too big 8. move ra->fns->flush to ra_gl_ctx instead 9. some other minor changes that I've probably already forgotten Note: This is one half of a major refactor, the other half of which is provided by rossy's following commit. This commit enables support for all linux platforms, while his version enables support for all non-linux platforms. Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the --opengl- options like --opengl-early-flush, --opengl-finish etc. Should be a strict superset of the old functionality. Disclaimer: Since I have no way of compiling mpv on all platforms, some of these ports were done blindly. Specifically, the blind ports included context_mali_fbdev.c and context_rpi.c. Since they're both based on egl_helpers, the port should have gone smoothly without any major changes required. But if somebody complains about a compile error on those platforms (assuming anybody actually uses them), you know where to complain.

vo_gpu: vulkan: initial implementation This time based on ra/vo_gpu. 2017 is the year of the vulkan desktop! Current problems / limitations / improvement opportunities: 1. The swapchain/flipping code violates the vulkan spec, by assuming that the presentation queue will be bounded (in cases where rendering is significantly faster than vsync). But apparently, there's simply no better way to do this right now, to the point where even the stupid cube.c examples from LunarG etc. do it wrong. (cf. https://github.com/KhronosGroup/Vulkan-Docs/issues/370) 2. The memory allocator could be improved. (This is a universal constant) 3. Could explore using push descriptors instead of descriptor sets, especially since we expect to switch descriptors semi-often for some passes (like interpolation). Probably won't make a difference, but the synchronization overhead might be a factor. Who knows. 4. Parallelism across frames / async transfer is not well-defined, we either need to use a better semaphore / command buffer strategy or a resource pooling layer to safely handle cross-frame parallelism. (That said, I gave resource pooling a try and was not happy with the result at all - so I'm still exploring the semaphore strategy) 5. We aggressively use pipeline barriers where events would offer a much more fine-grained synchronization mechanism. As a result of this, we might be suffering from GPU bubbles due to too-short dependencies on objects. (That said, I'm also exploring the use of semaphores as a an ordering tactic which would allow cross-frame time slicing in theory) Some minor changes to the vo_gpu and infrastructure, but nothing consequential. NOTE: For safety, all use of asynchronous commands / multiple command pools is currently disabled completely. There are some left-over relics of this in the code (e.g. the distinction between dev_poll and pool_poll), but that is kept in place mostly because this will be re-extended in the future (vulkan rev 2). The queue count is also currently capped to 1, because of the lack of cross-frame semaphores means we need the implicit synchronization from the same-queue semantics to guarantee a correct result.

RPI support This requires FFmpeg git master for accelerated hardware decoding. Keep in mind that FFmpeg must be compiled with --enable-mmal. Libav will also work. Most things work. Screenshots don't work with accelerated/opaque decoding (except using full window screenshot mode). Subtitles are very slow - even simple but huge overlays can cause frame drops. This always uses fullscreen mode. It uses dispmanx and mmal directly, and there are no window managers or anything on this level. vo_opengl also kind of works, but is pretty useless and slow. It can't use opaque hardware decoding (copy back can be used by forcing the option --vd=lavc:h264_mmal). Keep in mind that the dispmanx backend is preferred over the X11 ones in case you're trying on X11; but X11 is even more useless on RPI. This doesn't correctly reject extended h264 profiles and thus doesn't fallback to software decoding. The hw supports only up to the high profile, and will e.g. return garbage for Hi10P video. This sets a precedent of enabling hw decoding by default, but only if RPI support is compiled (which most hopefully it will be disabled on desktop Linux platforms). While it's more or less required to use hw decoding on the weak RPI, it causes more problems than it solves on real platforms (Linux has the Intel GPU problem, OSX still has some cases with broken decoding.) So I can live with this compromise of having different defaults depending on the platform. Raspberry Pi 2 is required. This wasn't tested on the original RPI, though at least decoding itself seems to work (but full playback was not tested).

hwdec/opengl: Add support for CUDA and cuvid/NvDecode Nvidia's "NvDecode" API (up until recently called "cuvid" is a cross platform, but nvidia proprietary API that exposes their hardware video decoding capabilities. It is analogous to their DXVA or VDPAU support on Windows or Linux but without using platform specific API calls. As a rule, you'd rather use DXVA or VDPAU as these are more mature and well supported APIs, but on Linux, VDPAU is falling behind the hardware capabilities, and there's no sign that nvidia are making the investments to update it. Most concretely, this means that there is no VP8/9 or HEVC Main10 support in VDPAU. On the other hand, NvDecode does export vp8/9 and partial support for HEVC Main10 (more on that below). ffmpeg already has support in the form of the "cuvid" family of decoders. Due to the design of the API, it is best exposed as a full decoder rather than an hwaccel. As such, there are decoders like h264_cuvid, hevc_cuvid, etc. These decoders support two output paths today - in both cases, NV12 frames are returned, either in CUDA device memory or regular system memory. In the case of the system memory path, the decoders can be used as-is in mpv today with a command line like: mpv --vd=lavc:h264_cuvid foobar.mp4 Doing this will take advantage of hardware decoding, but the cost of the memcpy to system memory adds up, especially for high resolution video (4K etc). To avoid that, we need an hwdec that takes advantage of CUDA's OpenGL interop to copy from device memory into OpenGL textures. That is what this change implements. The process is relatively simple as only basic device context aquisition needs to be done by us - the CUDA buffer pool is managed by the decoder - thankfully. The hwdec looks a bit like the vdpau interop one - the hwdec maintains a single set of plane textures and each output frame is repeatedly mapped into these textures to pass on. The frames are always in NV12 format, at least until 10bit output supports emerges. The only slightly interesting part of the copying process is that CUDA works by associating PBOs, so we need to define these for each of the textures. TODO Items: * I need to add a download_image function for screenshots. This would do the same copy to system memory that the decoder's system memory output does. * There are items to investigate on the ffmpeg side. There appears to be a problem with timestamps for some content. Final note: I mentioned HEVC Main10. While there is no 10bit output support, NvDecode can return dithered 8bit NV12 so you can take advantage of the hardware acceleration. This particular mode requires compiling ffmpeg with a modified header (or possibly the CUDA 8 RC) and is not upstream in ffmpeg yet. Usage: You will need to specify vo=opengl and hwdec=cuda. Note that hwdec=auto will probably not work as it will try to use vdpau first. mpv --hwdec=cuda --vo=opengl foobar.mp4 If you want to use filters that require frames in system memory, just use the decoder directly without the hwdec, as documented above.
