Instead of having a "cbr" setting that turns CBR on and off, adds a
"rate_control" parameter that sets the rate control method, which can be
one of the following: CBR, ABR, VBR, CRF.
If the "cbr" setting is used, it will throw a deprecation warning to the
log.
This just changes the x264 encoder settings; it doesn't actually change
the framerate of OBS. OBS will always output at a constant framerate
regardless of whether this option is on or off; this just changes how
the encoder encodes the data.
I feel like due to lack of user understanding, it's important to specify
that the higher the preset is (veryfast/superfast/ultrafast) the less
CPU that the encoder will use
Add CBR, CRF to properties so that it can be changed by the user. If
CBR is on, CRF will be disabled. Also added a 'Use Custom Buffer Size'
option to make it so that the buffer size will automatically be set to
the bitrate if its value is false. This is primarily a convenience
feature for users.
