[theora] ogg, ogm or mkv

[Orton AKINCI aka .-_-.]

i did so:i  run the "super" converted .ogm file through ogginfo and it gave the following... 

so does this mean "super" creates "pure ogg" files but name the extension as .ogm... and will it be "pure ogg theora orbis video" if i just rename the .ogm extension as .ogg?

Run it through ogginfo.  If the output is either:

Skeleton
Theora
Vorbis

or:

Theora
Vorbis

It's pure Ogg.
