# 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:

   ```bash
   bashCopyEdit$ cd Downloads
   $ tar xvf encoder_sdk.tar.gz
   ```
3. Install the headers and libraries (example for Linux):

   ```bash
   bashCopyEdit$ cp -v include/*.h /usr/local/include
   $ cp -v *.so /usr/local/lib
   ```
4. Create a `lcevc_eil.pc` file for `pkg-config`:

   ```ini
   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:

   ```bash
   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:

   ```bash
   bashCopyEdit$ cd GStreamer
   ```
2. Configure the build with Meson:

   ```bash
   bashCopyEdit$ meson setup $BUILD_DIR --pkg-config-path=$INSTALL_DIR/lib/pkgconfig -Dgst-plugins-bad:lcevcencoder=enabled
   ```
3. Build using Ninja:

   ```bash
   bashCopyEdit$ ninja -C $BUILD_DIR
   ```

***

### Run the GStreamer LCEVC Encoder Pipeline

Test the LCEVC encoding with a simple pipeline:

```bash
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

```
