View Full Version : [SOLVED] Mythexport file size

January 12th, 2011, 10:29 PM
I'm having a problem with mythexport file size when trying to export to an iPod compatible file. Everything was working a couple of months ago, but something has changed and I'm not sure what. I'm still on .23.1 and have enabled medibuntu for AAC.
If I run the PortableH264LowRes config against a 1280x720 mpeg2 file that is 4.9GB in size, I end up with a 480x320 h.264 file that is 4.9GB. In the past it would have been less than 500 MB.
I'm attaching a snippet from my mythexport.log.
Can anyone see what's going on? Or give me some troubleshooting ideas?
I can't fit a 5GB TV show on my iPod.
Thanks.

Hi

I think this should be a big tip

WARNING: library configuration mismatch

Looks as if ffmpeg has a problem, not sure what but that looks like the smoking gun. Have a look here http://ubuntuforums.org/showthread.php?t=1553321 or maybe here http://ubuntuforums.org/showthread.php?t=1472308 that might help.

Regards

Just wanted to close the loop on this.
The problem seems to have been related to this bug in the x264 library that was reverted:
https://bugs.launchpad.net/ubuntu/+source/x264/+bug/690296

After performing an apt-get upgrade:
Exporting a file that last week resulted in a 4.9GB file, now exports a 700MB file.
