buffering when skipping through movies

Getting a dedicated GPU is probably the most cost effective way to speed up transcoding. Ensure that the OS runs on a SSD.

Regardless of how fast your server is, if you skip ahead of where it has transcoded there will be some amount of delay vs direct play. The way ffmpeg works, it cannot simply skip ahead to where you selected. ffmpeg has to be stopped and another ffmpeg process started at the new position.
