Nicolas Dufresne	6d9c98ae5a	v4l2codecs: Add device enumeration ... This introduces a GstV4L2CodecDevice structure and helper to retrieve a list of CODEC device drivers. In order to find the device driver we enumerate all media devices with UDEV. We then get the media controller topology and locate a entity with function encoder or decoder and make sure it is linked to two V4L2 IO entity pointing to the same device node.	2020-03-31 09:34:05 -04:00
