Description Chris Ball 2010-03-29 16:30:59 UTC 
Hi,

I created a movie with a three-second PNG frame followed by an .mp4/h264 movie.  There weren't any errors setting up the timeline, or reported during rendering.

The created (Theora) movie shows the PNG correctly, but then hangs for several seconds on the first movie frame.  After the hang, video playback appears to be happening around twice as slow as it should be. mplayer reports:

Invalid frame duration value (4.560/0.040 => -4.520). Defaulting to 0.040 sec.

A movie created with the same video (and also in Theora) but without the PNG in front doesn't have this problem, which is why I think this is a PNG rendering bug.

I'm happy to provide more details if needed.

I've tried using -git and also the latest Ubuntu Lucid package, 0.13.4-0ubuntu.

I believe I'm also experiencing this bug, although I don't get any video at all after the PNG (it just keeps displaying it and playing my separate audio track).  It appears to be specific to PNG somehow, since a still image JPG does not give me this problem.  I am using the latest Ubuntu Lucid package as well.

Sorry, to clarify: I don't get any video when attempting to play the output Theora in Totem.  I do not have mplayer installed, so I didn't attempt that.

Similar issue here.

I have a PNG file at the start of my project which is followed by a video. Whatever length the PNG is displayed for, the following video misses off the start of playback.

Tried with 0.13.4.1 a few mins ago (built from git), same problem. I've run pitivi as follows:

 GST_DEBUG=2 PITIVI_DEBUG=5 pitivi > log 2>&1

Confirming the issue from the original bug description. It renders, but the output video is messed up. It has freezing frames, sound is desynchronized, and mplayer complains (as was reported).
