Adds VBR rate control mode, adds a lookahead option, adds psycho visual
tuning option, removes level property (now always set to 'auto'),
removes "2pass" option (replaced by new "Max Quality" preset which uses
2pass by default), modifies a few defaults, and updates their locale
text.
This implements a blacklist of devices that ship with NVENC libraries,
but do not support NVENC, which would cause the plugin to mistakenly
think that NVENC was available when it was not. If these devices are
the only NVIDIA devices on the system, consider NVENC unavailable.
This is much more efficient than spawning an encoder on startup to see
if NVENC is available, which would incur a ~500 millisecond hit on
startup. Additionally, also much less crash-prone.
Operating systems don't report monitors from 0, so OBS shouldn't
either. This avoids user confusion when display capture doesn't work.
This does not change monitor count internally.
They now provide ingest URLs on demand in their panel.
The ones in our list point to random OVH IPs that are likely assigned to
new customers by now and refuse the connection on TCP port 1935.
The GDI+ based Text Source actually uses Premultiplied Alpha. The edges
of the fonts are therefore incorrectly blended, causing ugly artifacts
especially if bright text above a bright background is used. Here's an
image comparing the new text blending (left) to before (right):

Additionally, the game capture has the same problem, so premultiplied
alpha is used there as well now.
A bit of a hack, but this is one of the more common errors that users
are encountering, so showing useful information will help cut down on
the number of support issues.
Input buffer by default is set to 2MB - for some sources, for example streaming
RTSP input over UDP, this is not enough and causes significant playback issues
that are not present while playing back the same source under ffplay/mpv.
It looks like someone actually started working on this feature as there are
translated strings, properties and everything ready - only the control was
missing from the UI. This commit adds that control.
Currently, the range is set to 1-16MB, step 1MB. This is somewhat arbitrary,
so suggestions to tweak this range with more real-world use cases are welcome.
