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, VP9, 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. + + * `vaapioverlay` is a accelerated compositor that blends or + composite different video streams. + |
