[PLUG] Creating DVD images via transcode, mystery error

[Douglas Lentz <dlentz@dca.net>]

Hi, all. I am attempting to create a DVD playable is a standard NTSC DVD 
player, from an .mpg file. I am following the instructions on the 
transcode_wiki 
(http://www.transcoding.org/cgi-bin/transcode?Tutorials/Authoring_PC_Media_To_DVD), 
and if anyone has ever looked at this page, it (1) lists all the 
dependencies required, and (2) the transcode command line needed to 
create the .ac3 file from your .mpg or .avi, followed by (3), a whole 
load of other stuff.

I have completed (1).  All dependencies have been built from source on 
my box, no binaries, rpms, etc were used.

When I run (2), transcode stops dead and reports "libavcodec.so.51: 
cannot open shared object file: No such file or directory".  The wiki 
states in the first paragraph that libavcodec is an absolute necessity. 
I investigated.  libavcodec.s0.51 lives happily in /usr/local/lib as a 
symbolic link pointing to the most recent version of libavcodec, which 
is libavcodec.so.51.9.0.  When I saw this error, two thoughts flashed 
through my mind:

a) transcode could not find libavcodec in /usr/local/lib
b) transcode could not follow a symbolic link.

But, I find both of these things hard to believe. I set a path to 
/usr/local/lib in shell var LD_LIBRARY_PATH. That did absolutely nothing 
at all. I replaced the symlink with a copy of libavcodec.so.51.9.0. No 
luck, same error message. I googled the error message and got nothing back.

I have never seen anything like this before. Something is going on that 
I don't understand. Does anyone have an idea what?

Alternatively, is the way that I'm trying to make a DVD crazy, and does 
anyone have another suggestion?

Thanks, everyone.
