### Video transcoding nodejs

Simple tutorial  of video transcoding with [fluent-ffmpeg](https://github.com/fluent-ffmpeg/node-fluent-ffmpeg).

### Requirments

- Nodejs versions with worker_threads & esmodule support

- ffmpeg ;

- ***Optional:*** Hardware acceleration requirements (Nvidia GPU with nvenc support Or  Apple Silicon devices)

### Features

- h264 compression with a crf of 28,

- Both single thread(singlethreaded.js) and multi-thread workloads(index.js&)

- Resizing to any resolution (when provided  an array of resolutions)

- Conversion to mp4

- Hardware accelerated video compression with cuda support(using h264_nevc) && videotool box for Mac

### usage

 **Note:**

 - Before testing, create a folder named compressed in the root directory.

 - For GPU acceleration, follow  the instructions [here](https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/) to add hardware acceleration support to ffmpeg. (Nividia only).




1. single threaded 


```bash

 node singlethreaded.js [InputFilenamewithExt]

 ```

 2. Multithreaded workload. 


```bash

 node  index.js [InputFilenamewithExt]

```

3. Clean up the example out files

```sh

  ./cleanup.sh 

```

4. Compare  video file sizes of original and compressed;

```bash

 ./checkVideoSize.sh

```

#### The End
