[HLUG] Source RPMs - update

[Jeff Tupholme]

Hi all,

Thanks for the helpful suggestions on this one a few weeks ago. I  
just wanted to report back and say that the experiment seems to have  
been 100% successful.

I installed the SRPM as usual, then unzipped the source tarball to  
add in my codec directory (from a zip file I downloaded from the  
codec provider, it's not in the base package for licensing reasons).  
I then simply edited the .spec file to suffix the version number (so  
I could later identify that this was a package of my own making) and  
add the configure switch to enable the new codec. Then I rebuilt the  
RPM and I could see in the output that the new codec was being compiled.

After that, I deleted the original RPM that I had previously  
installed and installed my modified version. Running 'ffmpeg - 
formats' against each version showed me that the codec in question  
was now listed where it wasn't before. I am now able to use the  
ffmpeg command to convert files into the format that I want.

By the way, for anyone on Red Hat-based systems who doesn't need to  
do this kind of stuff I'd thoroughly recommend YUM (http:// 
linux.duke.edu/projects/yum/), it's excellent.


Regards,

Jeff
