The nvgstcapture USB Camera Support. Use the following command to capture raw YUV I format using v4l2src and preview display with xvimagesink :. Both sample applications are based on GStreamer 1. They currently are supported only by OpenCV version 3. You can modify and rebuild the application to support GStreamer pipelines for CSI multi-instance capture and USB camera capture using the v4l2src plugin.
The application uses an OpenCV-based videosink for display. You can modify and rebuild the application to support GStreamer pipelines for different video encoding formats. The GStreamer Use the nvdrmvideosink plugin for development. For overlay Sink Video playback on overlay in full-screen mode , enter this command:. The following examples show how you can perform video playback using GStreamer To use all six overlays X11 must be disabled, since it occupies one window.
Disabling X11 also helps avoid memory bandwidth contention when using a non-X11 overlay. Use the following command to start the GStreamer pipeline using nveglglesink with the default X11 backend:.
This nvgstplayer You can also use nveglglsink with the Wayland backend, instead of the default X11 backend. Ubuntu That is, there is no UI support to switch to Wayland from Xorg. The following steps are required before you first run the GStreamer pipeline with the Wayland back end. They are not required on subsequent runs.
Stop the display manager:. For Weston 6. Create a temporary xdg directory:. Start the Weston compositor:. To run the GStreamer pipeline with the Wayland backend:. Use the following command to start the GStreamer pipeline using nveglglesink with the Wayland backend:. This sink element uses DRM to render video on connected displays.
Enter this command to start the GStreamer pipeline using nvdrmvideosink :. Property name. The following command illustrates the use of these properties:. It performs better than nveglglessink with NVMM buffers. The following command starts the GStreamer pipeline using nv3dsink :. The sink supports setting a specific window position and dimensions using the properties shown in this example:.
You can simulate a video decode pipeline using the GStreamer The sample application currently operates only with OpenCV version 3. You can modify and rebuild the application to support GStreamer pipelines for video decode of different formats. For display, the application utilizes an OpenCV based videosink component. The nvvidconv plugin currently supports the format conversions described in this section. Currently nvvidconv supports NVIDIA input and output formats for format conversion as described in the following table:.
Input Format. The nvvidconv plugin currently supports scaling with the format conversions described in this section. You can perform video transcoding between the following video formats. VP8 Decode to H. VP9 Decode to H. This section describes GStreamer This GStreamer The following are sample pipeline creation and application usage commands. Flip Method. Property value. Get information on the nvvidconv flip-method property with the gst-inspect To rotate video 90 degrees in a counterclockwise direction, enter the following command.
To rotate video 90 degrees in a clockwise direction, enter the following command:. To scale and rotate video 90 degrees counterclockwise, enter the following command:.
To scale and rotate video 90 degrees clockwise, enter the following command:. To scale and rotate video degrees, enter the following command:. Interpolation Method. Property Value. Get information on the nvvidconv interpolation-method property with the gst-inspect This release contains the gst-install script to install a specific GStreamer version. This section provides a procedure for building current versions of GStreamer. Execute the following command:. For example:. Export environment variables with the following command:.
Download the latest version of gstreamer available at:. The following are the files you need from version 1. Install needed packages with the following command:. Copy the downloaded tar. Uncompress the tar.
Build gstreamer in this example, gstreamer Build gst-plugins-base Build gst-plugins-good Obtain and build gst-plugins-bad Obtain and build gst-plugins-ugly Copy the nvidia gstreamer The nvidia gstreamer This section describes the nvgstcapture By default, the nvgstcapture The legacy nvcamerasrc plugin is no longer supported. To display command line option information, run the application with one of these command line options:. Other Command Line Options. Notes Examples. For CSI only, use nvoverlaysink or nvdrmvideosink.
CSI camera supports the following image resolutions for Nvarguscamera:. CSI camera runtime commands options for Nvarguscamera are described in the following table. USB camera runtime commands are described in the following table. The following table describes runtime video encoder configuration options supported for Nvarguscamera.
Rename or move files between runs to avoid overwriting results you want to save. This section describes the operation of the the nvgstplayer This table describes nvgstplayer The element file may contain an audio or video processing elements chain like this:. If a stream has multiple audio tracks, specifies the track number to play.
If a stream has multiple video tracks, specifies the track number to play. Point to start playback, in seconds from the beginning of the media segment. Operate in stealth mode, staying alive even when no media is playing. Operate in background mode, ignoring keyboard input. X coordinate for player window for non-overlay rendering. Y coordinate for player window for non-overlay rendering. Play video in non-full-screen mode for nveglglessink. Video Encoder Feature. Support is validated using the nvgstcapture application.
This camera is UVC compliant. The following USB 3. Changes based on exposure. Needs payment to vendor to get the support added to their firmware. V4L2 H. V4L2 VP8 video decoder. V4L2 VP9 video decoder. DRM videosink element. Video compositor. JPEG encoder element. JPEG decoder element. For an example, see the pipeline below.
For example, refer to the pipeline below. This pipeline is an example: gst-launch Drop 1 in 5 frames. Drop 1 in 3 frames. Production Branch New Feature Branch.
