Different format/codec support from MediaInfo

[SaintFlipper]

Noticing that mediainfo.js fails to extract information for some common (?) file types which MediaInfo displays full information for. For example all mediainfo.js displays for this .mov file:
https://dl.dropboxusercontent.com/u/36771332/P1010596.MOV
is
Format QuickTime
Format Info Original Apple specifications
and for this .mp4 file:
https://dl.dropboxusercontent.com/u/36771332/HEALTH-ECIGARETTES-USA.MP4
Format MPEG-4
Format profile Base Media / Version 2
Codec ID mp42 (mp42/mp41)
whereas MediaInfo displays full video and audio details for both.

From casual observation it looks like .mov files with format=MPEG-4 are fully decoded by mediainfo.js but those with format=QuickTime are not. Similarly .mp4 files with a codec ID that includes "isom" are fully decoded, but those with codec ID including "mp42" are not.

Has mediainfo.js been built with only a subset of the formats and codec support which MediaInfo has? Alternatively how to go about finding why these files (and many others) are not fully handled by mediainfo.js ? Are there any debug options that can be enabled, for example, which might provide useful diagnostic info?

Dupe of #4.

The file is correctly parsed if you set a bigger chunk size as suggested in the referenced issue.
