You can download the original videos captured by MH and the two muxed
from this URL: http://polimedia.upv.es/pub/matterhorn/mh_outsync.zip
Thanks,

It's really odd that one ffmpeg would have the issue and not another;
suggests to me that it's an ffmpeg bug not a matterhorn one.
If you ffmpeg -i the two media files with both sets of ffmpeg what do
the durations look like?
Which version of ffmpeg are you using on the workers?

Hi Christopher!
Any news in this issue?
I discovered that If I mux the video with and old ffmpeg I have
compiled in windows the output file is correct, but I don't know why
ffmpeg I have installed into the workers encodes the video bad.
Do you have any idea why is this happening? This is driving me mad.

Hi Christopher!
I don't see any info about dropping frames in the agent logs.

Hi Miguel,
Anything in your capture agent debug logs about dropping frames?
