Hello,

I switched from Ubuntu 6.10 (i386) to Gentoo (amd64) a few weeks ago and
managed to compile revision 1008 succesfully with these ./configure
options:

./configure --prefix=/usr --with-buildinfo=svn/recompile --enable-mmx
--enable-3dnow --with-external-ffmpeg

I did the distro switch because I liked the way you could adapt Gentoo
to your own wishes and switched from i386 to amd64 because I read
several times (mainly on the Heroine Virtual website) that Cinelerra was
made with 64 bit in mind. However, Cinelerra is not really usable for me
now.

I have an HDV camcorder (Sony HDR-HC1) and I capture the MPEG-TS stream
via Firewire using dvgrab with the HDV patch. After capturing I tried
two things with the *.m2t file. The first thing I tried was converting
it to PAL DV to get progressive video (Instead of using the Firewire HDV
-> DV conversion function function in the camcorder, this gives
interlaced PAL DV).The second thing I tried was converting it to 720p
H.264 with a low quantizer to maintain the high quality (I was also
thinking of converting it to 720p in a lossless format but I read that
Cinelerra doesn't support lossless formats.).

I did the DV conversion with these ffmpeg options:

> ffmpeg -i dvgrab-001.m2t -f dv -s 720x576 dvtest.dv

And the H.264 conversion by doing this:

> ffmpeg -i dvgrab-001.m2t -vcodec h264 -acodec aac -ab 256k -qmin 10 -qmax 15 
> -deinterlace -s 1280x720 testh264.mov

I also tried to encode H.264 into .mp4 and .avi containers but they give
the same problem that is mentioned below.

Both H.264 and DV crash the Cinelerra viewer. The video files load
perfectly fine, the index files are created, and I can load them into
the Cinelerra viewer. I can then view the video and navigate through
them in the viewer. But as soon as I navigated through the video for the
first time, the viewer crashes. It just doesn't respond to anything
anymore. I run Cinelerra from a terminal window, but the crash doesn't
give any output. The other three windows (Program, Compositor and
Resources) are not affected by the viewer crash and still respond to
everything.

(By the way, I have set all the right settings in "Settings -> Format...")

I have no idea how to solve this problem, especially because the crash
doesn't give any output. I never had this problem when I was running
Ubuntu. Any ideas?
