Hi Wolfgang,

Thanks for your hint!

Sorry for my poor English! I will try to explain carefully what I investigated:

1. use VLC GUI tool to rip DVD

VLC GUI -> LibVLC -> LibAV

so if VLC GUI failed to work, there might be some issues about LibVLC, then I
could not embedded LibVLC into K3B.

2. ffmpeg might be better choice than LibAV

because ffmpeg and LibAV are the same developers, and I directly use LibAV to
seek key frame from video https://github.com/isoft-linux/libKeyFrame

If others agree to use ffmpeg, I will take place of transcode, thoughts?

Regards,
Leslie Zhai
