This filter is now deprecated in favour of version 2.0

Inspired by audiograph, waveform is a plugin to overlay audio waveforms on video clips - useful for identifying sync issues and audio glitches.

No prizes for guessing what my favourite TV show is...

Improvements over audiograph are:

• A nicer, variable height overlay
• Separate graphs for each channel, works with an arbitrary number of channels
• Works with YV12 video, as well as YUY2/RGB24/RGB32
• Audio format is passed through unchanged
