# Video decode batch sample
|
|
|
|
This sample decodes multiple files using multiple threads, using the rocDecode library. The input is a directory of files and an input number of threads. The maximum number of threads is capped to 64.
|
|
If the number of files is higher than the number of threads requested by the user, the files are distributed to the threads in a round robin fashion.
|
|
If the number of files is lesser than the number of threads requested by the user, the number of threads created will be equal to the number of files.
|
|
|
|
## Prerequisites:
|
|
|
|
* 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
|
|
```
|
|
|
|
* On `RHEL`/`SLES` - install ffmpeg development packages manually or use [rocDecode-setup.py](../../rocDecode-setup.py) script
|
|
|
|
## Build
|
|
|
|
```shell
|
|
mkdir video_decode_batch && cd video_decode_batch
|
|
cmake ../
|
|
make -j
|
|
```
|
|
|
|
## Run
|
|
|
|
```shell
|
|
./videodecodebatch -i <directory containing input video files [required]>
|
|
-t <number of threads [optional - default:4]>
|
|
-d <Device ID (>= 0) [optional - default:0]>
|
