can't demux with ogminfo / need to re-pac OGV to MKV

[Jiri Navratil]

Hello,

I need to demux video files created with ffmpeg2theora 0.28+svn18147

I have ogminfo v1.5

and getting this error
(ogminfo.c) OGG stream 1 is of an unknown type (bad header?)
(ogminfo.c) OGG stream 2 is of an unknown type (bad header?)
(ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000)

Is possible, that ogminfo is older then ffmpeg2theora ? Or what can be the reason?

I need to re-pack my Vorbis + Theora from OGG to MKV. How I can do that, please? (I'm on Mac OS X and have Linuxes and OpenBSDs too)

Thank you,

You almost certainly shouldn't be using 'ogminfo' for anything.

The tools from liboggz are what you should use on Ogg/Theora+Vorbis files.

This is a pretty clear bug in mkvmerge. Potentially its fixed in a
later version than what you're running.

If not, at a minimum you should report it:
http://www.bunkus.org/videotools/mkvtoolnix/bugreports.html

You might want to try remuxing with ffmpeg, something like ffmpeg -i
input.ogv -acodec copy -vcodec copy output.mkv. But I make no
promises about the quality/validity of the files that come out.

Hello Gregory,

Thank you for you reply.

oggz-rip is demuxing fine

mkvmerge can't merge demuxed files, I will file a bug report

command
ffmpeg -i input.ogv -acodec copy -vcodec copy output.mkv
is working fine, so I have the solution. thank you!

Best regards,
Jiri

Again, you should not be using any "ogm" tools with Ogg/Theora files.

If you want to demultiplex an ogg file one tool which should work for
you is "oggz-rip".
