vo_drm: extract vt_switcher to drm_common
2015-04-19 07:39:58 +00:00
/*
* This file is part of mpv.

Relicense some non-MPlayer source files to LGPL 2.1 or later This covers source files which were added in mplayer2 and mpv times only, and where all code is covered by LGPL relicensing agreements. There are probably more files to which this applies, but I'm being conservative here. A file named ao_sdl.c exists in MPlayer too, but the mpv one is a complete rewrite, and was added some time after the original ao_sdl.c was removed. The same applies to vo_sdl.c, for which the SDL2 API is radically different in addition (MPlayer supports SDL 1.2 only). common.c contains only code written by me. But common.h is a strange case: although it originally was named mp_common.h and exists in MPlayer too, by now it contains only definitions written by uau and me. The exceptions are the CONTROL_ defines - thus not changing the license of common.h yet. codec_tags.c contained once large tables generated from MPlayer's codecs.conf, but all of these tables were removed. From demux_playlist.c I'm removing a code fragment from someone who was not asked; this probably could be done later (see commit 15dccc37). misc.c is a bit complicated to reason about (it was split off mplayer.c and thus contains random functions out of this file), but actually all functions have been added post-MPlayer. Except get_relative_time(), which was written by uau, but looks similar to 3 different versions of something similar in each of the Unix/win32/OSX timer source files. I'm not sure what that means in regards to copyright, so I've just moved it into another still-GPL source file for now. screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but they're all gone.

drm: rewrite based around vo_drm_state A longstanding pain point of the drm VOs is the relative lack of state sharing. While drm_common does provide some sharing, it's far less than other platforms like x11 or wayland. What we do here is essentially copy them by creating a new vo_drm_state struct and using it in vo_drm and context_drm_egl. Much of the functionality that was essentially duplicated in both VOs/contexts is now reduced simple functions in drm_common. The usage of the term 'kms' was also mostly eliminated since this is libdrm nowadays from a userspace perspective.

context_drm_egl: Introduce 30bpp support This introduces the option --drm-format (currently used only by context_drm_egl, vo_drm implementation is pending) which allows you to pick between a xrgb8888 or a xrgb2101010 visual for --gpu-context=drm. Requires a recent mesa (18.0.0_rc4 or later) to work. This also fixes a bug when using --gpu-context=drm on a 30bpp-enabled mesa (allow_rgb10_configs set to true). Previously it would've set up an XRGB8888 format at the DRM/GBM level, while a 30bpp EGLConfig would be picked, resulting in a garbled image.

context_drm_egl: add support for BGR surface formats The new GBM supporting nvidia drivers declare support for 10bit surfaces using BGR ordering, rather than RGB, so add support for them. We've also seen examples of hardware supporting BGR8888 but not RGB8888 so let's support those too. Of course, the nvidia EGL driver doesn't publish support for any 10bit formats so you can't actually do 10bit display. Perhaps they'll eventually fix that.

drm: use present_sync mechanism for presentation feedback A ton of code and drm-specific abstractions can be dropped with this. One important thing to note is that the usage of sbc is completely dropped here. The utility of that is not particularly clear since the sbc value was manually incremented before the flip and it's not as if the drm page flip event gives it to us like it does with the msec and ust. It can be reintroduced later if there is a need. For drm, we also add a present_sync_clear_values helper since all presentation feedback needs to be cleared on pause/resume for it.

vo: change vo->driver->wait_events to nanoseconds In many cases, this is purely cosmetic because poll still only accepts microseconds. There's still a gain here however since pthread_cond_timedwait can take a realtime ts now. Additionally, 37d6604d70c8c594de2817db26356c4c950ac0fd changed the value added to timeout_ms in X11 and Wayland to ensure that it would never be 0 and rounded up. This was both incomplete, several other parts of the player have this same problem like drm, and not really needed. Instead the MPCLAMP is just adjusted to have a min of 1.
