OGM Clips go white at beginning

[Carlo Capocasa]

Thanks for OpenShot! You're an inspiration not only for creating great software effectively but creating a fun and cheerful blog. It's so much fun to read!

I believe I found a bug in 0.9.34 on Ubuntu 9.04 64bit. I imported the SpiritOfUbuntu.ogv file from the ~/Examples/FreeCulture Shocase directory. Whenever I drag it to a track, or resize it, or slice it with the razor, the resulting file seems to have a few seconds of "white screen" at the beginning.

Hope this helps! Feel free to follow up with questions!

It doesn't happen with the example DIVX file from stage6.org.

I think this is the same as bug:
https://bugs.launchpad.net/openshot/+bug/423550. This is probably related
to a bug in MLT (of FFmpeg) with the codec in those videos. Can you do a "$
ffmpeg -i 'path_to_video', and post the output here. It should contain
information about the video container, codec, etc...

Thanks,
-Jonathan
