...heora stream on our server we ran into the following problem: When a client connects we send out the theora header pages followed by the actual live stream pages. The problem is that the first ogg data page does not have the right page number (2), which causes libogg to not want to decode the first _packet_ of that page. Since that first packet happens to contain the keyframe of the theora stream, most players (Mplayer) don't properly show the first frames until a new keyframe is received. This is not nice. In comming up with a solution we can see following scenarios: 1) libogg does not refuse t...

Hello, I would like to run a script over a speex file which determines, how long the speech contained in the speex file is. So I run through the ogg file, skip the first two ogg _pages_ (speex header and comment header, both contain IMHO only 1 ogg _packet_), and then count in any ogg page the number of the ogg _frames_ (which, unless I used -nframes while encoding, which I did not), and multiply this with .02 (20 milliseconds). I did this by hand, for example on the file I send yesterday when asking about the noise, so the output of the program is:...
