That new API was introduced and allows to have several native resources.
Thisuses that mechanisma for drm resources rather than the deprecated
opengl-cb structs.
This patch therefore add two structs that can be used with the drm atomic interop.
- mpv_opengl_drm_params : which will hold all the drm handles
- mpv_opengl_drm_osd_size : which will hold osd layer size
This commit adds a drm-osd-size=WxH parameter to commandline which
allows to define the OSD plane dimension. OSD can be upscaled to
screen resolution when having OSD at video resolution is too heavy.
This is especially useful for UHD modes on embedded devices where
the GPU cannot handle UHD modes at a decent framerate.
By blocking the VT switcher signal in the VO thread we get less races
and other oddities.
This gets rid of tearing (at least for me) when VT switching with
--gpu-context=drm.
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.
This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced
format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor
struct.
That struct holds dmabuf fds and information allowing zerocopy rendering
using KMS / DRM Atomic.
This has been tested on RockChip ROCK64 device.
The printout of available modes that you can get with --drm-mode=-1
(with -vo drm or --opengl-backend=drm) does not include the refresh
rate in the printout, which is quite useful to know, if one is to
choose for instance 23.98, or 24 Hz for film material.

I'm not sure what systems have <sys/poll.h> (maybe there are historical
reasons why some would), but POSIX defines <poll.h>. Although this code
is full of highly OS specific calls (like ioctl()), there's no reason
not to use the more standard include path.
- Change connector selection to accept human readable names (such as
eDP-1, HDMI-A-2) rather than arbitrary numbers.
- Change GPU selection to accept GPU number rather than device paths.
- Merge connector and GPU selection into one --drm-connector.
- Add support for --drm-connector=help.
- Add support for --drm-* in EGL backend.
- Refactor KMS; reduce state sharing across drm_common.
Reduces code duplication between OpenGL backend and DRM VO.
(The control() for OpenGL backend isn't sufficiently similar to the
VO's control() to consider merging it as a whole - I extracted only the
FPS code.)
For clang, it's enough to just put (void) around usages we are
intentionally ignoring the result of.
Since GCC does not seem to want to respect this decision, we are forced
to disable the warning globally.
Do this to make the license situation less confusing.
This change should be of no consequence, since LGPL is compatible with
GPL anyway, and making it LGPL-only does not restrict the use with GPL
code.
Additionally, the wording implies that this is allowed, and that we can
just remove the GPL part.
