This means the objectTypeIndication field of the DecoderConfigDescriptor 
is not 32 (0x20) or whatever the video decoder expects (registry key 
called ..../Decoders/Visual-20)
The content may be OK but the signalling is off.

This means bufferSizeDB is too small (typically 0). This should be 
bigger than any AU in the stream.
*** But it could also mean the player is totally confused.
Please check the values with mp4edit (Info view)

No, the problem is in the packaging tool.(unless the player is confused)

Why don't you try the content with Osmo4 ?

Do not use the GUI version: it is an older version that I cannot easily 
update. Use the latest mp4tool.exe (if you want support).

Use:
mp4tool -info foo.mp4
to see the info about the tracks. If the video is track 6, use:
mp4tool -export foo.mp4 6 video
This produces video.media, video.nhnt and video.info
