Nicolas Dufresne	09a9ffcda6	v4l2codecs: Implement flushing sequence ... This simply consit of cycling through STREAMOFF/STREAMON with stateless decoders.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	390cbe1f00	v4l2slh264dec: Add output format negotiation ... This allow negotiating the output format through caps. Some drivers can pipeline the decoder buffer through an image processor. This only support colorspace conversion for now.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	b107c20198	v4l2codecs: Fix bytesused value ... Pass the actual amount of bytes we have copied into the bitstream buffer. Also unmap the memory before queuing.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	3cc6643050	v4l2codecdecoder: Add support for dequeuing buffers ... This includings polling of the request and streamon/streamoff.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	a307499437	v4l2decoder: Add helpers to queue buffer and requests	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	d476e6d689	v4l2codec: decoder: Add allocation helper	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	7ae57631d4	v4l2codecs: Implement H264 format negotiation	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	a007e2dd9d	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.	2020-03-31 09:34:05 -04:00
Nicolas Dufresne	b7762fc332	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..	2020-03-31 09:34:05 -04:00
