| t is not possible to playback a segment of video before the first I frame in the segment, so if we are cutting out the I frame, this would explain the white output.
I'm thinking the same thing : good analyze. And i said more : that could explain the problem with the output video and output audio that some people was having met. And certainly the same thing for the ogg format because the I frame contain some informations that not having the others because it is a duplication partial or total of the I frames. -- White video output on some mpeg files https://bugs.launchpad.net/bugs/503112 You received this bug notification because you are a member of OpenShot Developers, which is subscribed to OpenShot Video Editor. 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. http://openshotusers.com/forum/viewtopic.php?f=11&t=121 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). _______________________________________________ Mailing list: https://launchpad.net/~openshot.developers Post to : [email protected] Unsubscribe : https://launchpad.net/~openshot.developers More help : https://help.launchpad.net/ListHelp
