| 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. |
