Previously we assumed mjpeg was always decoded to 422 but it seems some
cameras provide frames that decode to different pixel formats such as
420.
This change delays setting the obs frame pixel format until after we
have decoded the v4l2 frame.
fixes#5821
Adds frame time multiple based timeout option, instead of the hardcoded
1 second timeout.
Adds optional automatic device stream reset when the device times out.
Helps with devices that "lock up" or "freeze", for example Magewell and
Elgato USB HDMI capture devices.
The automatic reset is by default off and optional. Turning it on can
cause issues for devices that work but drop a lot of frames.
The capture loop errors are now logged as such.
Increased the amount of information logged in debug mode, including
state of all buffers on timeout.
Add device name to all capture loop debug output, especially useful when
debugging issues with multiple v4l2 video streams.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
Add BGRX and BGRA as supported video formats, since obs can handle them
directly. I unfortunately missed those when i initially wrote this
mapping due to my webcam not offering those formats.
Since the helper function also needs to pack/unpack the resolution, the
pack/unpack functions were moved to the helper library and prefixed with
v4l2_ in order to avoid possible collisions.
This moves some functions that are generic to a separate source
file. While doing so the api to those functions was improved to
be more generic and not depend on knowledge about the internal
structure of the plugin.
