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
|
||
|
|
```
|
