I wonder if we could skip the allocation query, and just use a some field,
e.g.:

  mpeg2videoparse ! "video/mpeg\(meta:Mpeg2Video\),headers=sequence+slice" !
...

If it's omitted, then everything is provided. At the same time, I don't fully
understand the need. In stateless CODEC, like VAAPI and V4L2 State Less, we
need everything. Is this granularity needed for CODEC parser ?
