LCEVC encoder build

Download and Install the LCEVC Encoder SDK

1. Register and download the SDK package:

   • Visit: https://download.v-nova.com

   • Select the appropriate pre-built encoder_sdk.tar.gz package (Ubuntu 20, Ubuntu 22, or Windows).

2. Extract and install SDK components:

   bashCopyEdit$ cd Downloads
   $ tar xvf encoder_sdk.tar.gz

3. Install the headers and libraries (example for Linux):

   bashCopyEdit$ cp -v include/*.h /usr/local/include
   $ cp -v *.so /usr/local/lib

4. Create a lcevc_eil.pc file for pkg-config:

   iniCopyEditprefix=/usr/local
   includedir=${prefix}/include
   libdir=${prefix}/lib
   
   Name: lcevc_eil
   Description: LCEVC Encoder EIL library
   Version: 3.11.3
   Libs: -L${libdir} -llcevc_eil
   Cflags: -I${includedir}

5. Install the .pc file:

   bashCopyEdit$ cp -v lcevc_eil.pc /usr/local/lib/pkgconfig

Build the LCEVC GStreamer Plugin

To enable the LCEVC encoder plugin during GStreamer build:

1. Navigate to your GStreamer project directory:

   bashCopyEdit$ cd GStreamer

2. Configure the build with Meson:

   bashCopyEdit$ meson setup $BUILD_DIR --pkg-config-path=$INSTALL_DIR/lib/pkgconfig -Dgst-plugins-bad:lcevcencoder=enabled

3. Build using Ninja:

   bashCopyEdit$ ninja -C $BUILD_DIR

Run the GStreamer LCEVC Encoder Pipeline

Test the LCEVC encoding with a simple pipeline:

bashCopyEdit$ gst-launch-1.0 videotestsrc pattern=ball num-buffers=1024 \
! video/x-raw,width=1920,height=1080,format=I420,framerate=25/1 \
! lcevch264enc plugin-name="x264" plugin-props="preset=superfast;tune=zerolatency" \
! h264parse ! mp4mux ! filesink location=lcevc-sample.mp4
