-This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using rocDecode library.
+# Video decode multi files sample
 
-This sample takes multiple files as a list and decodes each of them one after the other.
+The video decode multiple files sample illustrates the use of providing a list of files as input to showcase the reconfigure option in rocDecode library. The input video files have to be of the same codec type to use the reconfigure option but can have different resolution or resize parameters.
+
+The reconfigure option can be disabled by the user if needed. The input file is parsed line by line and data is stored in a queue. The individual video files are demuxed and decoded one after the other in a loop. Outpuot for each individual input file can also be stored if needed.
 
 ## Prerequisites:
 
-* Linux distribution
-  + 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`
-
-* rocDecode
-
-* CMake `3.5` or later
+* Install [rocDecode](../../README.md#build-and-install-instructions)
 
 * [FFMPEG](https://ffmpeg.org/about.html)
+
+    * On `Ubuntu`
+
+  ```shell
+  sudo apt install ffmpeg libavcodec-dev libavformat-dev libavutil-dev
   ```
-  sudo apt install ffmpeg
-  ```
+  
+    * On `RHEL`/`SLES` - install ffmpeg development packages manually or use [rocDecode-setup.py](../../rocDecode-setup.py) script
