# v4l2codecs

This plugin provides support for Video4Linux2 drivers implementing stateless video codecs. The plugin will generate elements based on the system capabilities. For this reason, this documentation may differ from output of running `gst-inspect-1.0` on your target.

If you are having issues getting any elementis to be registered, you may want to verify that your user have adequate permissions to access media and video devices. These Linux devices are usually found in `/dev/media*` and `/dev/video*`.

This documentation as been generated with the use of the environment variable `GST_V4L2_CODEC_GEN_DOC=1`. Using tis environment outside of the documentation generation will render your codecs unusable.
