Same problem, Ubuntu 10.04 and the 1.1.3 version of OpenShot from the
repositories. MLT? Don't know what that is, sorry.

The problem occurs for me on all mpg clips I tried so far. If I split a
clip the first part of the clip is unaffected, so it seems like it needs
the very first frame of the clip to be able to produce pictures. I have
also tried to trim clips. When I trim the end of a clip nothing bad
happens. The white frame thing only happens when I trim the beginning of
a clip, however at least once I tried it, it actually worked as it
should with no white frames.

I can include a short mpg file here if you want, but I noticed someone
else already did, so I'll wait for a request instead.

White video output on some mpeg files

Status in OpenShot Video Editor: Confirmed

Bug description:
Some mpeg files display a white screen after they have been cut with the razor tool. This issue was originally reported on the forum as white output when the video is muted, however I have found that just cutting a clip is enough to display the white output.

Steps to reproduce:

1. Drop the attached mpeg file on to the time line.
2. Cut the file into 3 roughly equal portions.
3. Set to play - when the playhead reaches the 2nd clip the video output is white.

The only other mpeg file I had (from a different source) wasn't affected by this, but it was only 11 seconds long, so not sure if it is related to length or some other property of the file.

Reproduced on bzr version 181, Jaunty 32 bit, MLT version 0.4.4 (from TJ's old repository).
