Hello,
I am writing an application for cutting h.264 streams and directly generating a mpeg2ts stream. I cut mainly hdtv-Streams recorded in 1080i. The audio tracks are often in MP2 and AC3. It works so far but I have two questions about the m2ts files.
1) Normaly a muxrate is calculated by VIDEO_BITRATE + AUDIO_BITRATE + 5%. But is this also ok for a bluray? I mean, is it possible to make such a calculation and use the result as a fixed muxrate? I can't find anything in the specs. Only that the max bitrate should be at 48 Mbps.
2) Is it important how big such a stream will be? I mean is it the same like VOB's for DVD?
regards,
Sven
