4.1.26 nvv4l2decoder
The OSS Gst-nvvideo4linux2 plugin leverages the hardware decoding engines on Jetson and DGPU platforms by
interfacing with libv4l2 plugins. It supports H.264, H.265, JPEG and MJPEG formats. The plugin accepts an
encoded bitstream and NVDEC hardware engine to decode the bitstream. The decoded output is in NV12 format.
For more details, refer to the official documentation at:
Note
: Only supported on NVIDIA platforms. Only supported on Linux.
4.1.26.1 Example Using gst-launch
This pipeline decodes an H.264 video file.
gst-launch-1.0 filesrc location=sample_1080p_h264.mp4 ! qtdemux ! h264parse !
nvv4l2decoder ! nvvideoconvert ! xvimagesink
Note
: The element ‘xvimagesink’ is only supported on Linux. It is recommended to use the ‘glimagesink’ or
‘d3dvideosink’ elements to display the window on Windows.
4.1.27 nvv4l2h264enc
The OSS Gst-nvvideo4linux2 plugin leverages the hardware accelerated encoding engine available on Jetson and
dGPU platforms by interfacing with libv4l2 plugins. The plugin accepts RAW data in I420 format. It uses the
NVENC hardware engine to encode RAW input. Encoded output is in elementary bitstream supported formats.

4.1.27.1 Example Using gst-launch
This pipeline encodes video to the H.264 format.
gst-launch-1.0 videotestsrc num-buffers=1000 ! "video/x-raw,format=(string)I420" !
nvvideoconvert ! "video/x-raw(memory:NVMM)" ! nvv4l2h264enc ! h264parse !
matroskamux ! filesink location=x1.mkv
4.1.28 nvv4l2h265enc
The OSS Gst-nvvideo4linux2 plugin leverages the hardware accelerated encoding engine available on Jetson and
dGPU platforms by interfacing with libv4l2 plugins. The plugin accepts RAW data in I420 format. It uses the
NVENC hardware engine to encode RAW input. Encoded output is in elementary bitstream supported formats.
