Introduces stream_http, an internal libcurl-driven backend for http://
and https:// URLs. Runs all transfers on a dedicated curl multi thread
with a producer-side ring buffer, and exposes HTTP/2 multiplexing,
QUIC/HTTP/3 (when libcurl supports it), HSTS and TCP keep-alive.
Should generally be more stable and faster than FFmpeg HTTP/1.1 impl,
additionally connections are kept-alive between files open, so if you
open playlist of network files and navigate through them, it will re-use
the same connection.
Build is gated on the new 'libcurl' meson option (auto). When disabled
or unavailable, mpv silently falls back to FFmpeg's HTTP implementation.
D3D11 only for now. Documentation says that only D3D11 and D3D12 is
supported, but it looks like Vulkan is possible too. But I realized this
after implementing this version. Vulan may be added later.
Fixes: #16613
subrandr is a subtitle rendering library which aims to render
SRV3 (YouTube) subtitles and WebVTT subtitles accurately.
Currently in mpv WebVTT subs are rendered via ffmpeg conversion to ASS
which throws away a lot of the style and completely disregards
the WebVTT non-region-cue positioning algorithm. Furthermore if
one wants to render some more complex SRV3 subtitles one has to
resort to external converters since it's not even supported by ffmpeg.
However subrandr is able to render SRV3 subtitles natively with support
for the most commonly used features. It can render ruby text without
relying on font metrics during conversion which is obviously fragile,
and it can perform correct scaling using the exact calculations used by
YouTube instead of making up ASS approximations. Similarly it follows
the WebVTT spec for the features of WebVTT that it supports (mostly).
It's not perfect of course and there's still many things it doesn't do
or does wrong but those are things that can be incrementally improved
outside of mpv.
in a13a674363 we set the default category
for the bundle to games, to get certain benefits like better rendering
timing, better bluetooth latency, better threading, etc (bundle only).
though this also prevents low power modes and wrongly categories the app
for spotlight search etc.
set the default category to video and add an option to set the category
to games if one wishes to.
We already have more than enough options. This doesn't need to exist.
Just use the environment variable if you really want to use this for
some reason.
