CEF_VERSIONallows to override the default CEF versionCEF_BUILDS_HOMEPAGE_URLallows to configure the URL of the website hosting CEF binaries. Default is https://cef-builds.spotifycdn.com
Third-party CEF builds
The official CEF builds hosted by Spotify do not support patent-encumbered codecs such as H.264. If that is a feature you need in your project or for some reason you need to customize the Chromium build flags, you need to rebuild CEF yourself. Thankfully at least two projects can help you with that daunting task:
- https://github.com/reinismu/cefbuild : Docker to build cef with all codecs
- https://github.com/philn/cef-build-box : Semi-automatic and reproducible CEF build
Run
The element can then be tested with:

cefsrc requires an X server environment on Linux, if none is available you can
run the previous commands with xvfb-run:
xvfb-run --server-args="-screen 0 1920x1080x60" gst-launch-1.0 ...
In addition, a wrapper bin is exposed, wrapping cefsrc and cefdemux, and
handling web+http, web+https and web+file protocols:
GST_PLUGIN_PATH=Release:$GST_PLUGIN_PATH gst-launch-1.0 \
cefbin name=cef cefsrc::url="https://soundcloud.com/platform/sama" \
cef.video ! video/x-raw, width=1920, height=1080, framerate=60/1 ! videoconvert ! xvimagesink \
