Multimedia API

The video decoder device node is /dev/nvhost-nvdec the multimedia API defines a helper class called NvVideoDecoder that creates new V4L2 video decoders, and it sets decoder capture and output plane formats. The example located in ~/tegra_multimedia_api/samples/00_video_decode provides more information on how to use the decoder.
