Great, on the website, it mentions "A live Matroska stream is different than
a file, because it may have no known end (only when the client disconnects).
For that the Segment *must* use the "unknow" size (all 1s in the size). The
other option would be to concatenate Segments with known sizes one after the
other. This solution allows a change of codec/resolution between each
segment which can be useful in some cases (switch between 4:3 and 16:9 in
some TV programs for example). "
I have test concatenate segments with know size together, but it dose not
work. Maybe the approach I try to concatenate the segments is not correct.
Is there anybody can help?
