gstcefsrc

Build

mkdir build && cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..
make

Windows Build:

mkdir build && cd build
cmake ..
cmake --build .

• Note: Add Debug folder to Path and GST_PLUGIN_PATH environment variables.

Run

The element can then be tested with:

GST_PLUGIN_PATH=Release:$GST_PLUGIN_PATH gst-launch-1.0 \
    cefsrc url="https://soundcloud.com/platform/sama" ! \
    video/x-raw, width=1920, height=1080, framerate=60/1 ! cefdemux name=d d.video ! \
    queue max-size-bytes=0 max-size-buffers=0 max-size-time=3000000000 ! videoconvert ! \
    xvimagesink audiotestsrc do-timestamp=true is-live=true  volume=0.00 ! audiomixer name=mix ! \
    queue max-size-bytes=0 max-size-buffers=0 max-size-time=3000000000 ! audioconvert ! pulsesink \
    d.audio ! mix.

Record website video + audio (with audiomixer)

GST_PLUGIN_PATH=Release:$GST_PLUGIN_PATH gst-launch-1.0 -e \
    cefsrc url="https://soundcloud.com/platform/sama" ! \
    video/x-raw, width=1920, height=1080, framerate=60/1 ! \
    cefdemux name=demux ! queue ! videoconvert ! \
    queue max-size-bytes=0 max-size-buffers=0 max-size-time=3000000000 ! x264enc ! queue ! \
    mp4mux name=muxer ! filesink location='test.mp4' \
    audiotestsrc do-timestamp=true is-live=true  volume=0.0 ! audiomixer name=mix ! \
    queue max-size-bytes=0 max-size-buffers=0 max-size-time=3000000000 ! audioconvert ! \
    audiorate ! audioresample ! faac bitrate=128000 ! queue ! muxer. \
    demux. ! queue ! mix.

This will work with sites with no audio as well

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 and uri 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 \
    cef.audio ! audioconvert ! audiomixer ! autoaudiosink

gst-launch-1.0 playbin uri=web://www.soundcloud.com/platform/sama
