Summary of the bug:
Not really sure if i am supposed to write these things here, as it's not really a bug, but here goes.
LAV Filter use ffmpeg for Decoding, and hence i direct this here.
The performance in decoding Lagarith and UT Video Codec are extremely bad, most of the time it's over 100% slower.
Originally i thought it was faster, either i have been mistaken or something has happened.
However, worth noting, Lagarith is limited to 2 threads in it's original decoder, however comparing the performance make this insignificant as ffmpeg will use more and still not be at the same pace.
How to reproduce:
Pretty sure you can just use:
ffmpeg -i "lagarith.avi" -o "Raw.avi"
so just decode a lagarith file to raw, and you will see the performance, than compare it to using the original decoder.
