I have a video stream and an audio stream, audio *.ogg

That audio stream should start about 4 seconds later than the video.

In Oggmux 1.0 I have no possibility to add a delay to the audio stream.



My workaround would be (as i have the original wave):

adding in headAC3he 0.23 frames, seconds to the wav-audio stream and encoding to ogg again....



But because the stream is very long, over 1 GB, and I have to do this procedure quite often (trial & error, because I want perfect sync between audio and video), it would be much easier, if I could add silence frames at the beginning to the existing ogg.

Then oggmux, and checking if sync.




So, is there a tool to add something to an ogg ?

The much talked about feature of connecting multiple files to a "chained stream" would make it possible to paste one ogg file to the beginning of another. But unfortunately you can't mux such streams with one that spans over both. I don't know any tricks to bypass this. Sorry.
