Okay couple of things:
1. the video has a 0 channel audio track, ie an audio track with no audio, which is kinda messing things up - you need to investigate why MCE is recording a zero hannel audio track
2. I've put a fix for this with the 01192013 BETA release of MCEBuddy which you can access via early release program. However this is a SLOW fix.
There is a faster way to fix this too but you need to be aware that the fast fix will work if ALL your videos have the same issue, i.e. the audio channel layout is identical, ie 2 audio tracks, 1st audio track is a zero channel audio track (imparied)
and the second one is a actual track OR if all your other videos are working using Fast Remuxing. Here is out how to try it and see if works:
After this line:
CopyRemux0=-vcodec copy -acodec copy -map 0:a -map 0:v -f mpegts
Add this line:
CopyRemux1=-vcodec copy -acodec copy -map 0:a:1 -map 0:v -f mpegt
What this does is that the regular remuxing fails (CopyRemux0), the next line CopyRemux1, it tells MCEBuddy to try to remux using the 2nd audio track (-map 0:a:1, the :1 after the 0:a refers to the 2nd audio track where as a :0 would refer to the 1st
audio track), which the correct audio track in case of this corrupted video.
How this will impact videos with other audio track layouts I cannot predict, it or may not work depending upon the configuration because CopyRemux0 will first run on the other WTv's and will fail on this file, after which CopyRemux1 will run.
So a 99% chance if you add the CopyRemux1 line EVERYthing will work OK if your other videos are working fine, but then again you can only confirm after trying it. AGain, this is just to speed things up. If you use the latest BETA it should work out of the
