Description Nicola 2013-04-28 12:46:53 UTC

basic tutorial 13 show how to do frame stepping, 

a classical frame step usage is to put the pipeline in paused state and start to move between frames, all is fine with jpeg video (all frame are keyframes), but with h264 video, after changing the pipeline direction the pipeline skip to a keyframe and so the next step is inaccurate (even 2-3 seconds),

example:

- pause pipeline
- step forward you see frame with ts 20
- step forward you see frame with ts 21
- change pipeline direction
- step backward, you should see frame with ts 20, this does not happen
 
I'm testing with mkv if this matter
