[Matroska-users] question about block in MKV files

Hello Cunsuo,
Each block has a timecode relative to the cluster timecode. So I think each slice or NALU with a different timecode should be mapped to a new block.

Subject: [Matroska-users] question about block in MKV files


I'm now working on a project related with matroska and I have some questions about the concept 'block'.
When I wrap a video stream, say H.264 stream, into a MKV file, should I map each slice or frame in the H.264 stream into each 'block' of the MKV file?
Or more commonly, when merge some source streams into a MKV file, how to decide which part of data should map into a 'block'?  How to define 'block' in a   precise and technical way?

Thank you for your time, have a nice day!
