Add a source property to enable buffering of frames, which is enabled by
default. This replaces the old "Use system timing" option by setting the
unbuffered source flag instead of using different timestamps.
While similar in intentions to the old option, this method should reduce
latency even more.
Fix bug 0000151: File loading not properly handled.

A newly selected font is not loaded properly if "read from file" is
active without a valid file. Old error handling lead to random memory
being displayed.

By default, video plays back based upon the timestamp for each frame,
and buffers the frames as needed to ensure that they play back at the
expected timing.
However, this can add some minor additional delay to the video, and may
not be ideal for certain devices such as webcams and generally any
device that has minimal latency. However, because those are the only
type of devices that typically have drivers, there's no real need to
have it on by default.
This adds an option to use buffering, and leaves it off by default.

Use the macro from the mac capture plugin to convert the fourcc integer
value to a string. This makes the debug statement for the pixel format
slightly more readable for the casual developer.
Remove the "Leave Unchanged" option for the input and video format
select.
This option was primarily added for cases in which the
resolution and framerate are set by another program or the capture
device itself and the values are not directly supported by the plugin.
One major usecase here would be capture devices for tv signals which
might be set to a spcific resolution and refresh rate, and might fail
to initialize in case any other combination of those settings is forced.
In case of the input this option did not make much sense, as the first
input is probably the best default option in most cases.
For the video format this default is even bad in some cases. If an
format emulated by libv4l2 is selected for example, this will usually
configure the device to use mjpeg with libv4l2 converting it to some
format obs can use. When obs or the source is then restarted and the
"Leave Unchanged" is enabled the plugin will fail, because it will only
notice that the device is set to mjpeg, without any knowledge about the
possibility of letting libv4l2 handle the conversion.
Using the first available and supported format is not nescessarily the
best choice, but still preferable to some random format that will
cause the plugin to not capture at all. Forcing a choice here will
hopefully also make the plugin behaviour more predicatable for the user.
Remove the constraint for device inputs to be of the type "CAMERA".
This was added under the false assumption that inputs of the type
"TUNER" are only used for control purposes.
This was caused to do the new RTMP code that added support for multiple
streams; the stream index needs to be reset on RTMP_Close otherwise it
will keep using the wrong stream information.
I had this issue where IDXGISwapChain::ResizeBuffers would fail in the
hooks, causing games to crash when they resized their backbuffers
because ResizeBuffers would return an 'invalid call' HRESULT value. In
the ResizeBuffers documentation it says that it will only happen if a
backbuffer currently has any outstanding references, but there's no way
this would happen unless ResizeBuffers internally calls Present or vise
versa.
After ResizeBuffers has been called, the very first call to Present will
somehow seemingly invalidate and/or destroy the current backbuffer.
It's very strange, but that seems to be what's going on, at least for
the game I was testing. So if you are performing a post-overlay
capture, then you must ignore the capture on the very first call to
Present.
It's Microsoft's code so you can't really know what's going on, you just
have to work around these strange issues seemingly in the dark.
Martell changed this function without realizing that this was calling a
function below it, not recursively calling itself. The reason why he
got the warning was because there was no forward declaration of the
function that was being called; I think he's used to C where only one
function definition can exist with the same name. In this case, it was
another function with the same name but with different parameters,
something that's permitted in C++. I wish I had realized this sooner.
This fixes the crashes people have been having with devices.
