VideoRecorder and PNGRecorder now have setting to decide how to name the files, with date prefix or sequentially numbered. A base name is given with session filename.
Added list of recent files, recent recordings, and folders list of media files. All saved in settings. Connect list of recent recordings with recorder.
Let gstreamer appsrc generate PTS automatically (seems to fix crash of encoding after long duration). Added test for GPU encoders and switch if enabled and available.
Keep track of actual FrameGrabber duration (different from timestamp). Two strategies for frame PTS: clock and framerate priorities. Implemented variable Framerate selection for VideoRecorder. Integration of all this in UserInterface and Settings.
(slow) and optimize distribution of gabbed frames to multiple recording
and streaming pipelines (e.g. record H264 *and* share stream on the
network). New implementation of Loopback source for LINUX using
v4l2loopback (experimental).
