Dispatch function for our custom plugin.
This handles the dispatch for the Xvid plugin. It passes data on to other functions for actual processing.

Routine to create a global VO/VOL header for MP4 container.
What we do here is extract the header from the Xvid bitstream as it is encoded. We also strip the repeated headers from the bitstream when a global header is requested for MPEG-4 ISO compliance.

frame | Pointer to encoded frame data |

Routine to correct a possibly erroneous framerate being fed to us.
Xvid currently chokes on framerates where the ticks per frame is extremely large. This function works to correct problems in this area by estimating a new framerate and taking the simpler fraction of the two presented.
avctx | Context that contains the framerate to correct. |
