Hmmm... This does sound tricky.  =)  OpenShot doesn't actually use "melt" to
export the video, but we use "libmlt", which is the same library under the
hood in "melt".  So, if MLT doesn't work with x264, then it won't work in
OpenShot.  This might be a question for the MLT mailing list (
mlt-devel@xxxxxxxxxxxxxxxxxxxxx).  I do know you can have a static build of
FFmpeg for MLT, but that would be part of the MLT build process.  Sorry I'm
not more help.  I've learned alot about MLT over the past year, but I'm no
expert packager. =)

Here is a link to the *MLT Build Tips* page.  It has an example of a
./configure command with static FFmpeg.

Best of luck,

Bug description:
I imported a bunch of images as a sequence, added a title one and an audio track. I tried exporting to mp4 h.264 and youtubehd but I always get audio without the video.

Here's how my project looks like, seems everything is fine with it:

http://www.ubuntu-pics.de/bild/28163/screenshot_05_tCLAYY.png
http://www.ubuntu-pics.de/bild/28162/screenshot_02_efdM2f.png

and the preview function does work as I'd expect it to be.

it worked fine with ogg for whatever reason.
