Example Usage

After installing GStreamer , it is possible to compile and run the flexhlsplugin.

On MacOS it might be necessary to set the PKG_CONFIG_PATH environment variable:

export PKG_CONFIG_PATH="/Library/Frameworks/GStreamer.framework/Versions/Current/lib/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"

An example pipeline:

export PROJECT_DIR=`pwd`
gst-launch-1.0 videotestsrc is-live=true ! \
    x264enc ! h264parse ! flexhlssink target-duration=4 \
    --gst-plugin-load=${PROJECT_DIR}/target/release/libflexhlssink.dylib

In another terminal run a simple HTTP server:

cd $PROJECT_DIR
python simple_http.py

Open the example player site https://hls-js.netlify.app/demo/ and play the http://localhost:8000/playlist.m3u8 playback URL.
