The problem for me is that Ihad two videos with different types of audio streams. ffmpeg would join them but they would not play past the point of the join.
So Iused mencoder like below and it joined the audio and made them both mp3 streams and it worked!
-oac mp3lame specifies the audio to be convered into an mp3 stream using the lame codec.
after the oac the two files are the ones to be joined.
the -o is the name of the outp........
Install Errors on Version 12:
This error happened on QEMU emulator version 2.11.1 pve-qemu-kvm_2.11.1-5
on Proxmox/Debian but installing on QEMU.12 on Centos 6 did not produce the error.
*Update it is not related to the OS or QEMU version. This happened in Centos 6 too after a second install.
What really causes this even though you successfully install........
The strange thing is that usually the first install or two will work on any new machine but then it suddenly won't. I had this experience on QEMU 2.13 on a different machine. There is something finicky or buggy about the CUCM installer even when choosing the same virtual hardware specs.

In my case I already copied the VIDEO_TS folder to my hard drive.
Here is the command for mencoder:
mencoder -dvd-device "myvideobackup/VIDEO_TS" dvd:// -ovc xvid -oac mp3lame -lameopts cbr:br=128 -xvidencopts pass=2:bitrate=-700000 -o myvideobackup.avi
Replace "-dvd-device myvideobackup/VIDEO_TS" with the location of your backup files or the /dev device of your DVD drive.
The -o myvideobackup.avi is of course the name o........

Mencoder is great, you can throw anything at it, including video files from your camera and have it encode into xvid or almost any other format.
In my case I took 640x480 video from my Canon and reduced the size by 1/3 with the options below (there are many other options that you can read about in the manual but I like to keep it simple).
mencoder -ovc xvid -oac mp3lame -xvidencopts fixed_quant=4 -o ........
