The Xavier incorporates hardware acceleration for 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 maximum number of simultaneous streams.
Standard | Profile | Resolution (Max Number of Streams) |
---|---|---|
H.265 |
|
|
|
| |
H.264 |
|
|
|
| |
VP9 |
|
|
Nvidia Hardware Accelerated Gstreamer Video Encoding Plugins
Plugin | Description |
---|---|
omxh264enc | OpenMAX IL H.264/AVC video encoder |
omxh265enc | OpenMAX IL H.265/AVC video encoder |
omxvp9enc | OpenMAX IL VP9 video encoder |
Multimedia API
The video decoder device node is /dev/nvhost-msenc
the multimedia API defines a helper class called NvVideoDecoder
that creates new V4L2 video encoders, and it sets encoder capture and output plane formats. The example located in ~/tegra_multimedia_api/samples/01_video_encode
provides more information on how to use the decoder.
