v4l2codecs: Introdude a V4L2 CODECs Accelerator plugin This plugin will support new CODECs uAPI in the Linux kernel. These consist of an accelerator interface similar to DXVA, NVDEC, VDPAU and VAAPI.

v4l2codec: Add allocator and pool implementation This is a pooling allocator and the buffer pool does nothing other then reusing the GstBuffer structure. Note that the pool is an internal pool, so the start/stop/set_config virtual functions are not implemented.

'gstv4l2codecallocator.c',
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.

v4l2codecs: Add skeleton of H264 decoder This introduces the skeleton of the H264 decoder. The plugin will list the devices and register a subclass of the GstV4L2CodecH264Dec base class. The subclass will pick the required specific information from the GstV4L2Device stored in the subclass structure.

v4l2codecs: Factor out plugin registration This introduce a common place for generic functions and factor out the plugin registration code. This code is nearly identical between implementation. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1216>

'gstv4l2codecvp8dec.c',
v4l2codec: Add GstV4L2Deocder helper object This is a GstObject which will be used to hold on media and video device file descriptor and provide abstracted ioctl calls with these descriptor. At the moment this helper contains just enough to enumerate the supported format. This part will be used by the plugin to register the CODEC specific elements..
