[mythtv-users] Nuvexport / ffmpeg / Floating point exception

[Giacomo Shimmings]

Thanks for the tip Chris, I did read the debug page - I should have been clearer that the reponse I posted was the forking output.

So this is what I have done:


----commands run as root------->


yum remove ffmpeg

rpm -e --nodeps ffmpeg

rpm -e --nodeps libavutil49-0.4.9-16_r19707.fc4.at

rpm -e --nodeps libavcodec51-0.4.9-16_r19707.fc4.at

rpm -e --nodeps libavformat50-0.4.9-16_r19707.fc4.at

wget http://rpm.forevermore.net/ffmpeg/ffmpeg-0.4.9-1.r5779.src.rpm

chown mythtv. ffmpeg-0.4.9-1.r5779.src.rpm

rpmbuild --rebuild ffmpeg-0.4.9-1.r5779.src.rpm

rpm -ivh /usr/src/redhat/RPMS/i386/ffmpeg-0.4.9-1.r5779.i386.rpm

So apart from the gcc version being different, my ffmpeg version looks the same as Wades.

However, I still get a floating point exception.  I run the debug switch and this is the output:


--------------------------------

Use the following commands:


system call:

Giving me the following output:

/tmp/fifodir_19569/audout: I/O error occured
Usually that means that input file is truncated and/or corrupted.

-----------------------

I get the same error with all the shows including ones recorded before and after 0.19->0.20 upgrade from ATrpms.  Is there any other information I should post Chris?
