Overview

This layer enables hardware assisted video decoding in Chromium via the Chromium V4L2VDA, using the v4l-gst libv4l plugin to connect it to the Renesas H/W video decoder available through GStreamer.

Currently, only the H264 video codec is supported.

Building

1. Add this layer to your bblayers.conf file

2. Add the following packages to your IMAGE_INSTALL:append variable in your local.conf

   • v4l-gst

3. bitbake as usual.

Configuration

The settings file for the v4l-gst bridge is located at /etc/xdg/libv4l-gst.conf. This file allows for specifying the GStreamer pipeline that the plugin will attempt to use to decode the video frames that it receives from the V4L2 interface.
