With the recent changes to the script it does not incur a startup delay
by default due to starting youtube-dl and waiting for it. This was the
main reason for making libmpv have a different default.
Starting sub processes from a library can still be a bit fishy, but I
think it's ok. Still mention it in the libmpv header. There were already
other cases where libmpv would start its own processes, such as the X11
backend calling xdg-screensaver. (The reason why this is fishy is
because UNIX process management sucks: SIGCHLD and the wait() syscall
make sub processes non-transparent and could potentially introduce
conflicts with code trying to use them.)
This was off for mpv CLI, but on for libmpv. The motivation behind this
was that it would be confusing for applications if libmpv continued
playback in a severely "degraded" way (without either audio or video),
and that it would be better to fail early.
In reality the behavior was just a confusing difference to mpv CLI, and
has confused actual users as well. Get rid of it.
Not bothering with a version bump, since this is so minor, and it's easy
to ensure compatibility in affected applications by just setting the
option explicitly.
(Also adding the missing next-release-marker in client-api-changes.rst.)
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.
for a reason i can just assume some key events can vanish from the
event chain and mpv seems unresponsive.
after quite some testing i could confirm that the events are present at
the first entry point of the event chain, the sendEvent method of the
Application, and that they vanish at a point afterwards. now we use
that entry point to grab keyDown and keyUp events. we also stop
propagating those key events to prevent the no key input' error sound.
if we ever need the key events somewhere down the event chain we need
to start propagating them again. though this is not necessary currently.
This should still allow user-set default options to override built-in
pseudo-gui while respecting user-set pseudo-gui options.
Pros:
- user option in default profile overrides built-in pseudo-gui's options
Ex: screenshot-directory overrides built-in pseudo-gui's
- user can "fix" pseudo-gui if some option like "force-window=no" is set
in default by setting "force-window=yes" in [pseudo-gui]
- `mpv --profile=pseudo-gui` will work as before
Cons:
- --show-profile=pseudo-gui won't display the built-in's options

The previous commit merely copied the profile string to a file (plus
changing how RPI-specific defaults are initialized), now make some
changes on top of it. In particular, remove the --input-lirc option,
which was removed a long time ago, but forgotten from the libmpv
profile.
Move the embedded string with the builtin profiles to a separate
builtin.conf file. This makes it easier to read and edit, and you can
also check it for errors with --include=etc/builtin.conf. (Normally
errors are hidden intentionally, because there's no way to output error
messages this early, and because some options might not be present on
all platforms or with all configurations.)
