Víctor Manuel Jáquez Leal	1a19a835a9	vah264enc: Avoid mapping coded buffer twice. ... Currently for copying the coded buffer onto a GStreamer buffer, the coded buffer is mapped two times: one for getting the size, and later for do the actual copy. We can avoid this by doing directly in the element rather than in the general encoder object.

Víctor Manuel Jáquez Leal	81b99c37d8	vah264enc: Single parameter array per picture. ... There's no need, at least in H.264, to hold a global parameter array, since there's no need to submit SPS, trellis, hdr or quality in every buffer, but only on IDR ones.

He Junyan	f17357f759	va: Add H264 encoder. ... This a new VA-API implementation of a H264 encoder. It can control the GOP and parameter settings, while the MV searching, VCL and the rate control algorithm are implemented by VA drivers and HW. It supports most of the common usage options in H264, but still lacks of look ahead, field, B frame weighted prediction, etc. Co-authored-by: Victor Jaquez <vjaquez@igalia.com> Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1051>	2022-03-01 10:53:50 +01:00
