gstreamer-vaapi consists in a collection of VA-API based
|
||
|
|
plugins for GStreamer and helper libraries.
|
||
|
|
|
||
|
|
vaapi<CODEC>dec 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 actual value of <CODEC> and the
|
||
|
|
underlying hardware capabilities. This plugin is also able
|
||
|
|
to implicitly download the decoded surface to raw YUV
|
||
|
|
buffers.
|
||
|
|
|
||
|
|
vaapi<CODEC>enc 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.) and the hardware
|
||
|
|
capabilities. By default, raw format bitstreams are
|
||
|
|
generated, so the result may be piped to a muxer, e.g. qtmux
|
||
|
|
for MP4 containers.
|
||
|
|
|
||
|
|
vaapipostproc is used to filter VA surfaces, for
|
||
|
|
e.g. scaling, deinterlacing (bob, motion-adaptive,
|
||
|
|
motion-compensated), noise reduction or sharpening. This
|
||
|
|
plugin is also used to upload raw YUV pixels into VA
|
||
|
|
surfaces.
|
||
|
|
|
||
|
|
vaapisink is used to render VA surfaces to an X11 or Wayland
|
||
|
|
display. This plugin also features a "headless" mode (DRM)
|
||
|
|
more suited to remote transcode scenarios, with faster
|
||
|
|
throughput.
