Freescale i.MX VPU hardware video decoding support for Chromium's GPU media stack

This repository contains sources which add hardware video decoding support to Chromium using the Freescale i.MX VPU. They are placed under the BSD 3-clause license. See the LICENSE file for details.

These sources are written against Chromium 48.0.2548.0.

Prerequisites

The i.MX platform requires the Vivante GPU drivers and userspace libraries to be installed. The patches make use of Vivante specific OpenGL ES 2.0 extension to ensure zero-copy display of decoded frames.

Also, Freescale's libfslvpuwrap library is required. Use at least version 1.0.45.

Furthermore, Chromium must be ran with its EGL backend enabled. Use the --use-gl=egl option for this.

Patching Chromium

  1. Copy the contents of src/ to the Chromium source tree.
  2. Apply all patches from patches/common/ in the source tree which are not version specific.
  3. If you are using a Chromium build that has already been patched with ozone-wayland, also apply the patches in patches/wayland/ . Note that it patches ozone-wayland files.
  4. Build Chromium. chromium://gpu should show video decoding as "Accelerated".
