Hi,
I was wondering if you can help me with this issue. When I start playing a video either through my tv or mezzmo, transcoding on the fly usually works fine but when it's a 1080p video the transcoding speed is around 22fps which is too slow and results in stuttering video. If I choose to pretranscode that video though, I get 40-50fps speed and therefore can start up the video a few seconds after pretranscoding has started to watch it without issues. Why is pretranscoding faster than transcoding?

Here is the ffmpeg output of the video being pretranscoded:
