* vo_rpi: handle rotationwm42016-01-051-1/+14
| | | | | Since the MMAL video renderer component supports exactly what we need, it's pretty simple.
* vo_rpi: work around firmware oddness leading to incorrect video rectwm42016-01-051-2/+4
| | | | | | | | | | | Apparently, the firmware will ignore pixel_x/pixel_y if the numeric value of them gets too high (even if they indicate square pixel aspect ratio). Even worse, the destination rectangle is ignored completely, and the video frame is simply stretched to the screen. I suspect this is an overflow or weird sanity check within the firmware. Work it around by limiting the fields to 16000, which is an arbitrary but apparently working limit.
* vo_rpi: fix previous commitwm42015-12-261-1/+1
| | | | Meh. Fixes #2639.
* vo_rpi: fix compilationwm42015-12-261-5/+1
| | | | | | | | | Untested, but should be fine. Broken by commit 0a0bb905. Also fix the include statement in context_rpi.c, which caused another compilation failure. Also untested. (Because I'm lazy.) Fixes #2638.
* vo_opengl: prefix per-backend source files with context_wm42015-12-191-1/+1
|
* vo_rpi: set aspect ratiowm42015-11-251-5/+8
| | | | | Otherwise, the MMAL output component will letter-box the video within the specified dest_rect while keeping square pixels.
* vo_rpi: log subtitle render timewm42015-11-251-0/+4
|
* vo_rpi: add an option to disable OSDwm42015-11-251-19/+25
| | | | | | The OSD takes up an entire fullscreen dispmanx layer. Although the GPU should be able to handle it (possibly even without any disadvantages), it'll still be useful for debugging performance issues.
* video/out: remove an unused parameterwm42015-10-031-1/+1
| | | | | | | | | | | This parameter has been unused for years (the last flag was removed in commit d658b115). Get rid of it. This affects the general VO API, as well as the vo_opengl backend API, so it touches a lot of files. The VOFLAGs are still used to control OpenGL context creation, so move them to the OpenGL backend code.
* vo_opengl: move shader file caching to video.cwm42015-09-231-1/+1
| | | | | | It's just about loading and cachign small files, not does not necessarily have anything to do with shaders. Move it to video.c where it's used.
* vo_rpi: fix compilationwm42015-09-111-2/+2
| | | | The recent OpenGL refactor commits forgot to update this file.
* vo_rpi: disable background by defaultwm42015-08-201-6/+13
| | | | And add an option to enable it.
* vo_rpi: use correct variable for osd layerwm42015-08-201-1/+1
| | | | | This is a cosmetic change, because the value is exactly the same. (The old code just duplicates the logic, sort of.)
* vo_rpi: fix blackscreen before the first subtitle/OSD is renderedwm42015-08-201-0/+1
| | | | | The OSD overlay wasn't initialized, so it remained solid black until the first time a subtitle line or an OSD element became visible.
* vo_rpi: redraw subtitles only on changewm42015-08-181-4/+15
| | | | | | | | | | | Since vo_rpi uses MMAL for video output, which is completely independent from the GLES overlay, we can just not redraw the GLES screen if subtitles do not change. (As a furhter optimization, the dispmanx overlay could be removed if nothing is visible. But I'm not sure if adding and removing the overlay frequently is a good idea for performance, so this could just as well go the other way.)
* vo_rpi: use EGL to render subtitleswm42015-08-181-124/+82
| | | | | | | | Slightly faster than using the dispmanx mess (perhaps to a large amount due to the rather stupid C-only unoptimized ASS->RGBA blending code). Do this by reusing vo_opengl's subtitle renderer, and vo_opengl's RPI backend.
* vo_rpi: fix NULL pointer derefwm42015-08-141-1/+1
| | | | Can happen in obscure situations and with hw decoding disabled.
* vo_rpi: simplify background handlingwm42015-08-131-19/+1
| | | | Apparently this is sufficient.
* vo_rpi: unregister vsync callbackwm42015-08-131-1/+3
| | | | Small bug, much pain.
* vo_rpi: skip OSD rendering when repeating frameswm42015-08-131-4/+8
| | | | It's unnecessary and slow. Doesn't help too much, though.
* vo_rpi: support display syncwm42015-08-101-4/+51
| | | | | | | | This VO is special because it normally doesn't block on vsync, but can be made to do so. Supposedly the MMAL video output API merely sets a "current frame" field when sending an output frame, and the firmware will pick up whatever frame that field is set to at the time of a vsync.
* vo_rpi: determine and return display refresh ratewm42015-07-271-0/+24
| | | | Reverse engineered from tvservice.c.
* vo_rpi: update renderer size on display size changes toowm42015-05-011-0/+2
| | | | | | | | (Not sure why it worked without this when I tested the previous changes.) Untested, but should be fine. This is equivalent what is done on e.g. panscan changes.
* vo_rpi: update display size on display mode switcheswm42015-04-301-0/+23
|
* vo_rpi: actually draw a black backgroundwm42015-04-301-23/+65
| | | | | | | | Also factor the display size initialization into a separate function. For some reason this seems to work, although setting the background color using this 1x1 pixel bitmap does not work. I blame the RPI beign a terrible piece of hardware with even worse drivers.
* vo_rpi: explicitly reference MMAL VC driverwm42015-04-131-0/+8
| | | | | | | This is optional, but ensures that linking with -Wl,--as-needed does not drop the MMAL VC driver. The driver normally "registers" itself in the library constructor, but since no symbols are explicitly referenced, the linker could remove it with as-needed enabled.
* video/out: fix screenshot image formatswm42015-04-071-1/+1
| | | | | | | Use variants without alpha. I skipped vo_sdl, because format selection seems a bit more complicated here, and nobody cares about vo_sdl anymore.
* RPI supportwm42015-03-291-0/+567
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).
