// This must be separate from qtprivate.h to keep everyone from
// depending on avcodec.h
// FFMPEG front end for quicktime.
// Getting ffmpeg to do all the things it needs to do is so labor
// intensive, we have a front end for the ffmpeg front end.


// This front end is bastardized to support alternating fields with
// alternating ffmpeg instances.  It drastically reduces the bitrate 
// required to store interlaced video but nothing can read it but 
// Heroine Virtual.
