Description Julien MOUTTE 2010-12-25 23:01:03 UTC 
VLC is using libebml and in this case doctype as a default value set to "matroska" which makes the file play fine.

In our case we will error out saying that there is not valid DocType.

I think both the demuxer and the typefinder should be more relaxed and assume "matroska" when no DocType is specified.

Thanks for the bug report,  it would be really helpful if you could attach the first 1MB of a sample next time, or point to one on the net...
