Allows rescaling resolution for GPU encoders and allows moving
rescaling for CPU encoders from CPU to GPU
Rescaling is implemented via core video mixes; encoders create
their own core mix with matching width/height/format/colorspace/
range when gpu scaling is enabled and no matching core video
mix exists
For mpegts output, used in rtmp-custom service, encoder settings
require:
- ADTS with fdk-aac.
For all non-rtmp protocols, one also requires:
- video encoder header repetition;
This future proofs the code against protocol addition.
Additionally, I've added a check against NULL audio settings, which was
in my fork but that I forgot to add in the PR [1].

YouTube Live now supports 5.1 surround sound.
The surround sound warning in Settings has been updated to reflect that.

Improve complicated Objective-C implementations in
mac-screen-capture implementation.
- Use `for` instead of overuse of block based iteration code.
- Use `YES` and `NO` for `BOOL` type instead of wrong `TRUE`, `FALSE`,
`true`, `false`.
- Use `length` to check empty string, omit unnecessary `nil` checks.
`screen_capture_build_content_list` or similar calls uses updated
`sc->show_hidden_windows` or similar flags, but these are not set
before calling these functions.
This software seems to be pre-installed on many Lenovo systems and has a
"Network Boost" feature that restricts data usage of background apps,
causing throughput issues when streaming with OBS.
Some options do not require a media source restart. Saving source
unchanged source settings should also not trigger a restart.
I tried to also make it so speed changes do not require a restart by
manipulating the elapsed timestamp for the source, but it sometimes
causes the first few milliseconds after saving settings to be rough or
slightly distorted. I am also unsure whether a/v frame buffers should be
cleared on a speed change (and how to) so I made it so restarts are
required for speed changes. Chiyo also mentioned that successive quick
speed changes will cause maximum audio buffering (which I was able to
reproduce once).
Nonlocal file playback is unaffected, and will cause the media source to
restart because I am not aware of the possible consequences and because
there's no restart button for it.
Changing "Apply alpha in linear space" is only visible after a few
milliseconds (when mp_media_next_video is called for new frames).
If `is_stinger` and `full_decode` are toggled during runtime, even
though it shouldn't be possible as they are not accessible in the UI,
a media restart will be triggered.
Notable changes:
* deps.qt: Remove Qt 5 builds
* deps.qt: Update Qt 6 build scripts
* deps.ffmpeg: Update dependencies for OBS CMake 3.0 upgrade
* deps.windows: Update dependencies for OBS CMake 3.0 upgrade
No dependency versions have changed.
This update is to unblock work on the Windows "CMake 3.0" upgrade and
dropping Qt 5 support.
When changing audio channels, sample rate, or audio buffering settings
multiple times by hitting `Apply` button, the internal `changed` state
got corrupted. To avoid this, set the changed state when changed
something, but do not clear the changed state.
