vaapi: change license to LGPL Originally mpv vaapi support was based on the MPlayer-vaapi patches. These were never merged in upstream MPlayer. The license headers indicated they were GPL-only. Although the actual author agreed to relicensing, the company employing him to write this code did not, so the original code is unusable to us. Fortunately, vaapi support was refactored and rewritten several times, meaning little code is actually left. The previous commits removed or moved that to GPL-only code. Namely, vo_vaapi.c remains GPL-only. The other code went away or became unnecessary mainly because libavcodec itself gained the ability to manage the hw decoder, and libavutil provides code to manage vaapi surfaces. We also changed to mainly using EGL interop, making any of the old rendering code unnecessary. hwdec_vaglx.c is still GPL. It's possibly relicensable, because much of it was changed, but I'm not too sure and further investigation would be required. Also, this has been disabled by default for a while now, so bothering with this is a waste of time. This commit simply disables it at compile time as well in LGPL mode.

video: add vaapi decode and output support This is based on the MPlayer VA API patches. To be exact it's based on a very stripped down version of commit f1ad459a263f8537f6c from git://gitorious.org/vaapi/mplayer.git. This doesn't contain useless things like benchmarking hacks and the demo code for GLX interop. Also, unlike in the original patch, decoding and video output are split into separate source files (the separation between decoding and display also makes pixel format hacks unnecessary). On the other hand, some features not present in the original patch were added, like screenshot support. VA API is rather bad for actual video output. Dealing with older libva versions or the completely broken vdpau backend doesn't help. OSD is low quality and should be rather slow. In some cases, only either OSD or subtitles can be shown at the same time (because OSD is drawn first, OSD is prefered). Also, libva can't decide whether it accepts straight or premultiplied alpha for OSD sub-pictures: the vdpau backend seems to assume premultiplied, while a native vaapi driver uses straight. So I picked straight alpha. It doesn't matter much, because the blending code for straight alpha I added to img_convert.c is probably buggy, and ASS subtitles might be blended incorrectly. Really good video output with VA API would probably use OpenGL and the GL interop features, but at this point you might just use vo_opengl. (Patches for making HW decoding with vo_opengl have a chance of being accepted.) Despite these issues, decoding seems to work ok. I still got tearing on the Intel system I tested (Intel(R) Core(TM) i3-2350M). It was also tested with the vdpau vaapi wrapper on a nvidia system; however this was rather broken. (Fortunately, there is no reason to use mpv's VAAPI support over native VDPAU.)

vaapi: try dealing with Intel's braindamaged shit drivers So talking to a certain Intel dev, it sounded like modern VA-API drivers are reasonable thread-safe. But apparently that is not the case. Not at all. So add approximate locking around all vaapi API calls. The problem appeared once we moved decoding and display to different threads. That means the "vaapi-copy" mode was unaffected, but decoding with vo_vaapi or vo_opengl lead to random crashes. Untested on real Intel hardware. With the vdpau emulation, it seems to work fine - but actually it worked fine even before this commit, because vdpau was written and designed not by morons, but competent people (vdpau is guaranteed to be fully thread-safe). There is some probability that this commit doesn't fix things entirely. One problem is that locking might not be complete. For one, libavcodec _also_ accesses vaapi, so we have to rely on our own guesses how and when lavc uses vaapi (since we disable multithreading when doing hw decoding, our guess should be relatively good, but it's still a lavc implementation detail). One other reason that this commit might not help is Intel's amazing potential to fuckup anything that is good and holy.

video: have a generic context struct for hwdec backends Before this commit, each hw backend had their own specific struct types for context, and some, like VDA, had none at all. Add a context struct (mp_hwdec_ctx) that provides a somewhat generic way to pass the hwdec context around. Some things get slightly better, some slightly more verbose. mp_hwdec_info is still around; it's still needed, but is reduced to its role of handling delayed loading of the hwdec backend.

vaapi: replace error macro implementation The current check_va_status() function could probably be argued to be derived from the original VAAPI's patch check_status() function, thus GPL-only. While I have my doubts that it applies to an idiom on this level, it's better to replace it. Similar idea, different expression equals no copyright association. An earlier commit message promised this, but it was forgotten.

video: reduce error message when loading hwdec backend fails When using --hwdec=auto, about half of all systems will print: "[vdpau] Error when calling vdp_device_create_x11: 1" this happens because usually mpv will be linked against both vdpau and vaapi libs, but the drivers are not necessarily available. Then trying to load a driver will fail. This is a normal part of probing, but the error messages were printed anyway. Silence them by explicitly distinguishing probing. This pretty much goes through all the layers. We actually consider loading hw backends for vo_opengl always "auto probed", even if a hw backend is explicitly requested. In this case vd_lavc will print a warning message anyway (adjust this message a bit).

vaapi: determine surface format in decoder, not in renderer Until now, we have made the assumption that a driver will use only 1 hardware surface format. the format is dictated by the driver (you don't create surfaces with a specific format - you just pass a rt_format and get a surface that will be in a specific driver-chosen format). In particular, the renderer created a dummy surface to probe the format, and hoped the decoder would produce the same format. Due to a driver bug this required a workaround to actually get the same format as the driver did. Change this so that the format is determined in the decoder. The format is then passed down as hw_subfmt, which allows the renderer to configure itself with the correct format. If the hardware surface changes its format midstream, the renderer can be reconfigured using the normal mechanisms. This calls va_surface_init_subformat() each time after the decoder returns a surface. Since libavcodec/AVFrame has no concept of sub- formats, this is unavoidable. It creates and destroys a derived VAImage, but this shouldn't have any bad performance effects (at least I didn't notice any measurable effects). Note that vaDeriveImage() failures are silently ignored as some drivers (the vdpau wrapper) support neither vaDeriveImage, nor EGL interop. In addition, we still probe whether we can map an image in the EGL interop code. This is important as it's the only way to determine whether EGL interop is supported at all. With respect to the driver bug mentioned above, it doesn't matter which format the test surface has. In vf_vavpp, also remove the rt_format guessing business. I think the existing logic was a bit meaningless anyway. It's not even a given that vavpp produces the same rt_format for output.

video: warn if an emulated hwdec API is used mpv supports two hardware decoding APIs on Linux: vdpau and vaapi. Each of these has emulation wrappers. The wrappers are usually slower and have fewer features than their native opposites. In particular the libva vdpau driver is practically unmaintained. Check the vendor string and print a warning if emulation is detected. Checking vendor strings is a very stupid thing to do, but I find the thought of people using an emulated API for no reason worse. Also, make --hwdec=auto never use an API that is detected as emulated. This doesn't work quite right yet, because once one API is loaded, vo_opengl doesn't unload it, so no hardware decoding will be used if the first probed API (usually vdpau) is rejected. But good enough.
