{{DISPLAYTITLE:NVIDIA Jetson Xavier - HDAV Subsystem Video Encoder|noerror}}

The Xavier incorporates hardware acceleration for the encoding of various coding standards through the use of its NVIDIA Multi-Standard Video Encoder. The following table describes the supported video standards, the corresponding resolution, and the maximum number of simultaneous streams.

==Multimedia API==

The video decoder device node is <code>/dev/nvhost-msenc</code> the multimedia API defines a helper class called <code>NvVideoDecoder</code> that creates new V4L2 video encoders, and it sets encoder capture and output plane formats. The example located in <code>~/tegra_multimedia_api/samples/01_video_encode</code> provides more information on how to use the decoder.
