LCEVC Encoder Build Instructions
|
||
|
|
--------------------------------
|
||
|
|
|
||
|
|
1. Download and manually install the pre-built V-Nova's LCEVC Encoder SDK:
|
||
|
|
|
||
|
|
- You can get a trial pre-built V-Nova's LCEVC Encoder SDK directly just by signing up at: https://download.v-nova.com
|
||
|
|
- There should be at least a pre-built `encoder_sdk.tar.gz` package for Ubuntu 20, Ubuntu 22 and Windows.
|
||
|
|
- Once you have downloaded the correct package for your system, extract the tar file:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cd Downloads
|
||
|
|
$ tar xvf encoder_sdk.tar.gz
|
||
|
|
```
|
||
|
|
|
||
|
|
- Now you need to manually install the headers, libraries and plugins in $INSTALL_DIR
|
||
|
|
- For example, $INSTALL_DIR for Linux can be `/usr/local`:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cp -v include/*.h /usr/local/include
|
||
|
|
$ cp -v *.so /usr/local/lib
|
||
|
|
```
|
||
|
|
|
||
|
|
- Afterwards, you need to manually create the `lcevc_eil.pc` package config file with this contents:
|
||
|
|
|
||
|
|
```
|
||
|
|
prefix=/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}
|
||
|
|
```
|
||
|
|
|
||
|
|
- And finally install it under `/usr/local/lib/pkgconfig`
|
||
|
|
|
||
|
|
```
|
||
|
|
$ cp -v lcevc_eil.pc /usr/local/lib/pkgconfig
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Build LCEVC encoder (lcevcencoder) plugin for GStreamer:
|
||
|
|
|
||
|
|
- You can now build the lcevcencoder plugin by using the '-Dgst-plugins-bad:lcevcencoder=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:lcevcencoder=enabled
|
||
|
|
$ ninja -C $BUILD_DIR
|
||
|
|
```
|
||
|
|
|
||
|
|
3. Run GStreamer LCEVC encoder pipeline:
|
||
|
|
|
||
|
|
- If the build was successful, you can test LCEVC encoding (H264) with the following pipeline:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ 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
|
||
|
|
```
|
||
|
