Audio sync discrepancy with some content.
Not all libavformat supported formats are seekable.
ogg is currently broken.
- Multiple mp3 uses in a single instance causes crash (patch
- available on request - submitted to ffmpeg mailing list).
mpeg seeking is inaccurate - doesn't seek to i-frames so you may
get junk for a few frames.

+
+ This producer is has two roles:
+
+ 1. it handles the mappings of all file names to the other
+ producers;
+ 2. it attaches normalising filters (rescale, resize and resample)
+ to the producers (when necessary).
+
+ This producer simplifies many aspects of use. Essentially, it
+ ensures that a consumer will receive images and audio precisely as
+ they request them.
