API

transformStream = transcode(options)

Transcode an incoding audio or video stream.

Options include:

{
  acodec: 'audio-codec-to-use', // defaults to 'copy'
  vcodec: 'video-codec-to-use', // defaults to 'copy'
  format: 'container-format' // defaults to mp4
}

FFMPEG is used for the actual transcoding so make sure that is in your PATH. PRs for more options welcome.

writableStream = transcode.info(cb)

Get media info about an incoding stream. Returns an object that looks like this:

{
  vcodec: 'the-video-codec-used',
  acodec: 'the-audio-codec-used',
  width: videoWidth,
  height: videoHeight
}
