[mythtv-users] Cannot rip dvds at less than perfect quality

Wed Apr 21 22:23:51 EDT 2004

Further troubleshooting:

I  did a perfect rip on a small title, and threw it into the 
temp/TITLE/vob directory so that I could execute the transcode command 
from the command line.  The transcode command displayed in the mtd.log 
file doesn't have quotes around directories with spaces in the names, 
but I'm pretty sure the mythtv code takes care of that for us, so I 
added them in myself.

The output looked pretty good, finding the input file, parsing the 
command line arguments, then it ran into some trouble:
--------------------------------------
...
[transcode] V: video buffer     | 10 @ 720x480
[transcode] warning : 
/var/tmp/transcode-root/usr/lib/transcode/import_vob.so: cannot open 
shared object file: No such file or directory
(decoder.c) loading audio import module failed
[transcode] failed to init import modules
[transcode] critical: plug-in initialization failed
--------------------------------------
A quick scan of the system revealed that import_vob.so resides in 
/usr/lib/transcode - I have no idea why it's looking in 
/var/tmp/transcode-root/usr/lib/transcode for anything.  Anyways, I 
created a symbolic link to /usr/lib/transcode from there, and ran it 
again (I'm pretty sure I should NOT have to do this).  I got a bit 
further this time:
--------------------------------------

[transcode] warning : failed to init DivX 5.0 Codec
[transcode] warning : (encoder.c) video export module error: init failed
[transcode] critical: failed to init encoder
No accelerated IMDCT transform found
-----------------------------------------------
So I just did a find on my system, and libdivxencore* doesn't exist.  
Previous installs following Jarod's guide have worked great, but the 
last 2 I've done over the last 4 days or so have had this problem.  Is 
there a package with encoders missing or something?  I'm currently 
searching around to see if I can find the proper encoders.

Thank you very much for the patience and suggestions, as well as the 
gentle prods of which files to look at.  As always, I am very open to 
any help.
