Lossless mode is set through the preset setting, and the profile ffmpeg
setting was incorrectly being set as lossless instead.

This reverts commit 997f05f1.

Previously it wouldn't necessarily remove the "cbr" setting when
switching the program to use "rate_control".

This reverts commit 8d520b97.

This can actually cause a hard lock due to the windows API when
destroying window capture.  When the graphics thread locks the source
list for doing tick or render, and then the UI thread tries to destroy a
source, the UI thread will wait for the graphics thread to complete
rendering/ticking of sources.  The video_tick of window capture would
then check windows in the same process and try to query the window's
name via GetWindowText.  However, GetWindowText is synchronous, and will
not return until the window event has been processed by the UI thread,
so it will perpetually lock because the two threads are waiting for each
other to finish.

Allows window capture to capture windows of the current process, and
adds windows of the current process to the end of the window list.

On windows, if you were saving a file name or directory with characters
that are not of the current windows character set, it could cause the
file saving process to fail.  This fixes it so that on windows it uses
wmain and converts the unicode command line to a UTF-8 command line,
which works with FFmpeg.

This flag should be reset when the user changes the game capture
settings.

If a process is already hooked, immediately initialize the capture
rather than wait for the processes to initialize or wait for the timer
to trigger.

Prevents game capture from acting as a global source.  This fixes an
issue where a game capture in another scene could capture a window and
prevent a separate game capture in the current scene from being able to
capture that same window.

Completely shut down monitor capture when it's not being shown in the
program (for example in a different scene).  This fixes an issue where
it would cause lag when a game enters fullscreen mode.

After testing, LA_ICQ may not always be supported, so use regular ICQ
for recordings instead.  Also fixes a bug where simple output mode
wouldn't even use LA_ICQ.

Instead of just remuxing from FLV to MP4, allow remuxing to/from the
various container formats that are available.

In the advanced output section of settings, when a different encoder is
set, it would try to pass over settings from the other encoder, which
may or may not be fully compatible with different encoders.  Instead,
just set it to defaults if it's on an encoder that's different from the
currently loaded encoder.

When settings are being loaded in to the settings dialog, it would
recreate the encoder property views more than once unnecessarily.

The "cbr" setting has been deprecated, so if the user is using that
setting for any of the encoders, convert it to set "rate_control" to
"CBR".

Additionally, if an encoder is using x264 with VBR and the buffer size
is set to 0, change the rate control mode to CRF.

When using simple output mode, previously NVENC did not support a
constant quality rate control method, and you'd have to use VBR with
bitrate.  However CQP has since been added to NVENC, and it's preferable
to use for recording when available instead of using VBR.

For setting CBR on encoders, use "rate_control" set to "CBR" instead of
setting the "cbr" setting (which is now deprecated) to true.

Instead of using "cbr" to set the rate control mode for encoders (which
is now considered deprecated for all encoders), set "rate_control" to
"CBR".

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.

Using the "cbr" parameter is now considered deprecated in favor of using
"rate_control" to set the rate control method.

Instead of using an option that turns CBR on/off, adds rate control
methods: VBR, CBR, CQP, Lossless.

This moves lossless from being a preset to being a rate control method.

This reverts commit cb24080d.

This commit is being reverted due to the fact that it breaks common
dialogs such as the open/save file dialogs, the dialogs would cause the
UI thread to lock up.

The plugin that required this will have to be modified to accommodate
this situation.

When clicking the transition properties button and creating the
context menu with properties/rename, it would create actions that also
included a source reference, but the parent of those actions was the
main window instead of the menu, so those actions would stay created
until the main window was destroyed.

This would cause bugs with saving/loading scenes where children of that
transition would also be perpetually referenced.

So instead of using the main window, just use a pointer to the menu
itself as the parent so that when the menu is destroyed, the actions are
also destroyed, and the source refs released.

Fixes an issue where the main window would load off-screen if its last
saved position was inside a monitor that no longer exists.

The bitrate for the properties was capped at 90000, which is a bit low.

The bitrates were a bit higher than they probably should be.

When rendering the deinterlaced surface, it would not take in to account
whether the async surfaces were marked as flipped or not.

Transition audio was programmed to stop if there is no queued audio from
both sources.  Because of that, when a source's audio started after the
transition started, it would cause audio from the source to be excluded
from the transition until the transition had completed because the audio
had already been marked as stopped.

Instead, if there's no audio from the transition sources, the audio
should only be marked as stopped when video has stopped.  This allows
the to/from sources to have an opportunity to start/restart audio during
the transition safely.
