would be possible...............

would be possible to just write a new mpg1 driver that supports
also movies encodec in mpg4 other than the 3 standars film/pal and ntsc?

naturally old mpg1 formats should be playable throught it,
i mean something to substitute,not to add, the mpg1 driver working on our pc.

would be hard to do this??

B frames are a basic feature of video compression,old mpg1 supports them,

seems that we were using the "most avanced" video codec(mpg4)without that basic feature

and this cause of the "open" avi format!

and this is ridicolous!!

You have to crawl before you can walk and then run. The MPEG4 specs have been around a while. But they have only recently become to be implemented en mass. We could have developed the MP4 containers first but have nothing to put in them. Or we could design the codec first and then the file format to enable the use of further features later. By doing so it has allowed us to use the codec for some time now. Even if it was only ever in AVI. But things are progressing rappidly.

and maybe to write a new mpg driver with mpg4 would be more simple than create a new format,
with the possible advantage that most players and editors should support it already

avi sucks very much, we should have started with this at least one year before......

(another thing, anyone knows if asf or wmv use B frames?
and how is with real video ?)

[Neo Neko]

Technically AVI has B frame support. It can have B frames. It is just not flexible with em. As for ASF or WMV only Microsoft can play them and they do not want any one else to. So ASF or WMV is out for me. I have not checked to see if they could better support it. But we have OGG and MP4 comming swiftly down the pipe. So it should only be a matter of time. Not to mention MCF!
