"Found no video or audio data"

Hybrid analysis the input with a bunch of tools, but the main work is done by:
a. FFmpeg
b. MPlayer
c. MediaInfo

so let's look at the output of those in the debug output.
FFmpeg reports:

Mplayer reports it can't analyse the source, which is why Hybrid doesn't like the file.
Hybrid used:

to analyse the file and mplayer reports no audio or video for it just:

no info about av at all.

So audio is vp8 and video is ogg vobis audio inside a webm container like the file I attached, but the attached file

-> Remuxing the file to mkv with MKVToolnix might help.
Also if you can share a small sample I can look at it some more, may be I can find a workaround for your files.
