谁能告诉我这个的主要用处和优缺点。。。。。。。。
转自doom9:
1. Variable frame rate video.
2. An actual set of specs.
3. Active developers.
4. Opensource tools.
5. Defined specs for every informational MP3 ID3 tag, and almost every other tag in other containers including APEv2, Ogg, RIFF, AVI, Extended RIFF, WMP9, CD-Text, and a few others.
6. More extensible for the future. (This is subjective as the future isn't here, but it was a top priority to ensure anything* could be stored in Matroksa for the next 10 years.)
7. matroska can hold any number of audio streams, even if different audio codecs and/or sampling rates were used. Also the DShow filter will support this ( hopefully this year still )
8. matroska can deal with any VfW and/or ACM codecs out there, without having to know what codec it actually is ( see WMV9 VCM )
9. matroska has defined 'native' MPEG4 modes, for simple, simple avanced and advanced mode
10. matroska is supporting b-frames natively, without simply taking the VfW hackery with dummy frames and the like. In addition to that 5 more frame types are defined for future use
11. matroska specs do support h.264 with all the advanced features like improved streaming using NALUs ( video packet distribution with a priority ) already
12. matroska files can be stuffed with additional EDC/ECC(FEC) elements in a very flexible way, for enhanced mode2form2 or UDP streaming support |
