 Summary of the bug: The asyncts filter doesn't exist in the default
 builds. Is this by design? According to the documentation this option
 doesn't appear to be deprecated.

 I'm trying to use this option because the audio is drifting out of sync
 with the video slowly over an hour. At the end of the hour the converted
 file has a 5 second audio drift. The original TS file has perfect audio
 video sync right through. Any ideas?
