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.
