AFAIK the Ogg container could do that fine, but that's not the purpose 
of Ogg. Ogg is a free content distribution standard, and you should take 
care to only use the compression formats which are allowed/ment to be in 

For your purpose, you can use MKvtoolnix/mkvmerge 
(http://mkvtoolnix.matroska.org) and put your Theora stream into the MKV 
container. matroska is a general use container and not ment to be used 
for content distribution, so its the perfect solution for your own 
files, using a combination of whatever compression formats you like to 
use for them.
