### Prerequisites setup script
|
||||
|
||||
For your convenience, we provide the setup script, [rocDecode-setup.py](https://github.com/ROCm/rocDecode/blob/develop/rocDecode-setup.py), which installs all required dependencies. Run this script only once.
|
||||
|
||||
```shell
|
||||
python3 rocDecode-setup.py --rocm_path [ ROCm Installation Path - optional (default:/opt/rocm)]
|
||||
--runtime [ Setup runtime requirements - optional (default:ON) [options:ON/OFF]]
|
||||
--developer [ Setup Developer Options - optional (default:OFF) [options:ON/OFF]]
|
||||
```
|
||||
|
||||
## Installation instructions
|
||||
|
||||
The installation process uses the following steps:
|
||||
|
||||
* [ROCm-supported hardware](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/reference/system-requirements.html) install verification
|
||||
|
||||
* Install ROCm `6.3.0` or later with [amdgpu-install](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/how-to/amdgpu-install.html) with `--usecase=rocm`
|
||||
|
||||
>[!IMPORTANT]
|
||||
> Use **either** [package install](#package-install) **or** [source install](#source-install) as described below.
|
||||
|
||||
### Package install
|
||||
|
||||
To install rocDecode runtime, development, and test packages, run the line of code for your operating
|
||||
system.
|
||||
|
||||
* Runtime package - `rocdecode` only provides the rocdecode library `librocdecode.so`
|
||||
* Development package - `rocdecode-dev`/`rocdecode-devel` provides the library, header files, and samples
|
||||
* Test package - `rocdecode-test` provides CTest to verify installation
|
||||
|
||||
#### Ubuntu
|
||||
|
||||
```shell
|
||||
sudo apt install rocdecode rocdecode-dev rocdecode-test
|
||||
```
|
||||

||||
```shell
|
||||
sudo zypper install rocdecode rocdecode-devel rocdecode-test

||||
>[!NOTE]
|
||||
> Package install auto installs all dependencies.
|
||||
|
||||
> [!IMPORTANT]
|
||||
> `RHEL`/`SLES` package install requires manual `FFMPEG` dev install
|
||||
|
||||
### Source install
|
||||
|
||||
To build rocDecode from source and install, run:
|
||||
|
||||
```shell
|
||||
git clone https://github.com/ROCm/rocDecode.git
|
||||
cd rocDecode
|
||||
python3 rocDecode-setup.py
|
||||
mkdir build && cd build

#### Run tests
|
||||
|
||||
```shell
|
||||
make test
|
||||
```
|
||||
> [!IMPORTANT]
|
||||
> make test requires `FFMPEG` dev install
|
||||
|
||||
>[!NOTE]
|
||||
> To run tests with verbose option, use `make test ARGS="-VV"`.
|
||||
|
||||
#### Make package

||||
|
||||
The installer copies:
|
||||
|
||||
* Libraries into `/opt/rocm/lib`
|
||||
* Header files into `/opt/rocm/include/rocdecode`
|
||||
* Samples folder into `/opt/rocm/share/rocdecode`

||||
|
||||
To verify your installation using a sample application, run:
|
||||
|
||||
```shell
|
||||
mkdir rocdecode-sample && cd rocdecode-sample
|
||||
cmake /opt/rocm/share/rocdecode/samples/videoDecode/
