# Video Decode Multi Files Sample
|
|
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using rocDecode library.
|
|
|
|
This sample takes multiple files as a list and decodes each of them one after the other.
|
|
|
|
## Prerequisites:
|
|

* [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`
|
|
|
|
* rocDecode
|
|
|
|
* CMake `3.5` or later
|
|
|
|
* [FFMPEG](https://ffmpeg.org/about.html)
