|
|||
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.
|
||||
* `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.
|
||||
|
||||
* `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.
|
||||
* `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
