This is a video specific sink used to test video CODEC conformance. This is similar
to a combination of filesink and testsink, but will skip over any type of
padding that GStreamer Video library introduces. This is needed in order to obtain the
correct checksum or raw yuv data.
This element currently support writing back non-padded raw I420 through the
location property and will calculate an MD5 and post it as an element message
of type conformance/checksum. More output format or checksum type could be
added in the future as needed.
