# Video Decode Sample
|
|
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using VAAPI.
|
|
|
|
This sample supports both YUV420 8-bit and 10-bit streams.
|
|
|
|
## Prerequisites:

|
|
+ Ubuntu - `20.04` / `22.04`
|
|
|
|
* [ROCm supported hardware](https://rocm.docs.amd.com/en/latest/release/gpu_os_support.html)
|
|
|
|
* Install [ROCm 5.5 or later](https://rocmdocs.amd.com/en/latest/deploy/linux/installer/install.html) with `--usecase=graphics,rocm --no-32`
|
