gstreamer-vaapi consists in a collection of VA-API based plugins for
GStreamer and helper libraries.
- * `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4:2, H.264 AVC,
- H.264 MVC, VP8, VC-1, WMV3, HEVC videos to VA surfaces, depending
- on the underlying hardware capabilities. This plugin is also able
- to implicitly download the decoded surface to raw YUV buffers.
-
- * `vaapiencode_<CODEC>' is used to encode into MPEG-2, H.264 AVC,
- H.264 MVC, JPEG, VP8, HEVC videos, depending on the actual value
- of <CODEC> (mpeg2, h264, etc.). By default, raw format bitstreams
- are generated, so the result may be piped to a muxer.
- e.g. qtmux for MP4 containers.
