/* TODO
* Review before stable
* - We use a profile for video recording properties and here we have
* elements for image capture. This is slightly inconsistent.
* - One problem with using encodebin for images here is how jifmux
* autoplugging works. We need to give it a higher rank and fix its
* caps (it has image/jpeg on sink and src pads). Preliminary tests
* show that jifmux is picked if image/jpeg is the caps of a container
* profile. So this could work.
* - There seems to be a problem with encodebin for images currently as
* it autoplugs a videorate that ony starts outputing buffers after
* getting the 2nd buffer.
