This article describes how to select a GPU device on a multi-GPU system.

## 1. Media (VAAPI based) elements

The [GStreamer VAAPI plugin](https://gstreamer.freedesktop.org/documentation/vaapi/index.html)
supports the `GST_VAAPI_DRM_DEVICE` environment variable, which allows
selecting a GPU device for VAAPI elements (and `decodebin3` element in case
it internally works on VAAPI elements).

The `GST_VAAPI_DRM_DEVICE` environment variable expects the GPU device
driver path. The `/dev/dri/renderD128` path typically represents the first
GPU device on the system, `/dev/dri/renderD129` represents the second, etc.

For example, the following command forces VAAPI elements (and
`decodebin3`) to use the second GPU device:

```bash
export GST_VAAPI_DRM_DEVICE=/dev/dri/renderD129
```
