Thank you for your reply, Francesco Romani. I did not come across the page
you referred to in your reply before posting my message, so I'm sorry I did
not properly include the information that you need. Below I have included
the missing pieces.
[System]
I am running Gentoo Linux 2.6.17-r2 on a x86_64 platform.
[Transcode]
I've manually recompiled transcode. I retrieved the source from
http://www.linuxfromscratch.org/blfs/view/svn/multimedia/transcode.html (for
some reason, the files that I downloaded from
http://www.transcoding.org/cgi-bin/transcode?Download were corrupt). I used
the following options for ./configure:
./configure --disable-mmx --disable-3dnow --disable-sse --disable-sse2
--disable-altivec --enable-gtk --enable-libjpeg --with-x
These were derived from the USE flags that were enabled and disabled when I
installed transcode in Gentoo using emerge.
The compiler and installer did not give any errors.
Below I've included the output of "gdb -q transcode". I hope this will
provide you with the information required. Thank you for your help.
Kind regards,
Martijn
