I'm using mediainfo on several ubuntu systems. I've noticed an inconsitency between different versions of mediainfo.
**command: mediainfo FLI0938_AMF[SV\=de]donoma[UNRESTRICTED][CRF16][OMUTDT]_B4E2AFB65E0E2190DFCE151E3954662E.mp4 **
ubuntu 12.04, MediaInfoLib - v0.7.52, (mediainfo 0.7.52-1 from official DEB package):

As you can see, there are several infos missing on ubuntu 13.10, most importantly (for me) the number of audio channels, but also the Encoding settings in the Video section. I wasn't able to get it working as expected, even though I spent several hours trying different versions and package repositories. I also tried two different workstations - same story. The number of audio channels in another file (AAC stereo track) was shown correctly though.
I've attached a truncated version of the video file (MP4Box -splitx 0:1 FLI0938_AMF[SV=de]donoma[UNRESTRICTED][CRF16][OMUTDT]_B4E2AFB65E0E2190DFCE151E3954662E.mp4)
The file has channels info in the 0.7.69 Windows build, I need to find out the specific issue on the Linux build.
