LCEVC Decoder Build Instructions

1. Build and install the V-Nova's LCEVC Decoder SDK (LCEVCdec):

• Checkout the repository: https://github.com/v-novaltd/LCEVCdec

$ git clone https://github.com/v-novaltd/LCEVCdec.git
$ cd LCEVCdec

• Build and install the SDK
• $BUILD_DIR and $INSTALL_DIR are local build and install directories

$ mkdir $BUILD_DIR
$ cd $BUILD_DIR
$ cmake  -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$INSTALL_DIR ..
$ cmake --build .
$ cmake --install .

2. Build LCEVC decoder (lcevcdecoder) plugin for GStreamer:

• You can now build the lcevcdecoder plugin by using the '-Dgst-plugins-bad:lcevcdecoder=enabled' meson flag
• $BUILD_DIR and $INSTALL_DIR are local build and install directories
• For example:

$ cd GStreaner
$ meson setup $BUILD_DIR --pkg-config-path=$INSTALL_DIR/lib/pkgconfig -Dgst-plugins-bad:lcevcdecoder=enabled
$ ninja -C $BUILD_DIR

3. Run GStreamer LCEVC decoder pipeline:

• If the build was successful, you can test LCEVC decoding with the following pipeline:

$ gst-launch-1.0 filesrc location=/home/user/lcevc-sample.mp4 ! qtdemux ! h264parse ! openh264dec ! lcevcdec ! videoconvert ! autovideosink

• LCEVC decoding should also work with autoplugging elements:

$ gst-launch-1.0 playbin uri=file:///home/user/lcevc-sample.mp4
