# nalu-chunker

A transform stream which chunks incoming AVC/H264 bitstream into NAL unit chunks.

## API

```

const fs = require('fs');

const { H264Decoder } = require('h264decoder');

const NaluChunker = require('@eyevinn/nalu-chunker);

const naluChunker = new NaluChunker();

const decoder = new H264Decoder();

naluChunker.on('nalu', nalu => {

  console.log(`Got NAL unit ${nalu.type}`);

  const ret = decoder.decode(nalu.data);

  if (ret === H264Decoder.PIC_RDY) {

    console.log(`Got frame ${decoder.width}x${decoder.height}`);

    // decoder.pic contains YUV420p

  }

});

fs.createReadStream('file.h264')

  .pipe(naluChunker)

```
