[Bug 719296] Re: choppy playback on timeline

 

Ok, I tried this now. Ffmpeg plays fine, but it is stuttering with Melt.
Here is output from "ffmpeg -i":

Title:
  choppy playback on timeline

Status in OpenShot Video Editor:
  Incomplete

Bug description:
  I have tried out 1.3 a bit, and the first thing I noticed was that
  playback on the timeline is very choppy. Also the playhead "shivers"
  during playback. When I double click a fil in the Project Files area,
  it plays just fine. But it is not possible for me to edit anything
  like this. The same video files have been fine in previous versions.

  Linux Mint 9
  OpenShot 1.3 from PPA, upgraded via Synaptic
  Video files I have tried are motion jpg .avi, 640x480, 30 fps.
