camerabin2: Adding basic property and signals Adds mode property to camerabin2, allowing users to select between video and stills capture. Also adds start/stop capture actions to trigger and stop capturing

camerabin2: Handle vidbin state change individually Keep vidbin state locked to avoid it going to playing without being used and leaving an empty file created. Check the docs on the code for details on the handling.

camerabin2: Rename variables Use better name for the variables, making the code clearer. Also keep a ref for some internal elements to avoid fetching them by name when needed later.

camerabin2: Reset all elements on video recording branch before capture We need to reset the elements from the video recording branch, including the queue and capsfilter in order to clear the eos state and activate the pads. This makes it possible to record multiple videos with camerabin2 in a sequence, otherwise the source would get a unexpected return and push EOS, stopping the whole pipeline.

camerabin2: adds location property Adds a location property to enable applications to select the captured files names. Locations are handled just like multifilesink ones Also disables -Wformat-nonliteral to allow to use non-literals on g_strdup_printf on camerabin and generate a sequence of locations for captures.

camerabin2: Implement previewing Implement previewing functionality using 2 properties. A boolean (post-previews) that indicates if previews should be posted, and a GstCaps (preview-caps) to provide the desired preview caps. wrappercamerabinsrc implements previewing by supplying the captured image to a pipeline to adapt it to the required caps before posting.
