Why so many IDs for the same codec?
That's an incomplete list, too... As for the rational, Michael mentioned turning on special codec workarounds by fourcc's.
"H264","h264" MPEG-4 Part 10 "vrbs" Xiph.org Vorbis "\x00\x50" MP1, MP2 "\x00\x55" MP3 .... * note: the list is not a complete list and values can be added in the future
Since I don't care about the issue, I don't mind if you add such a thing to the spec... For you this is fundemental. For me, this is bikeshed.
So given a NUT file, how do you know which codec is used if there is no official list of codec IDs?
I dunno, how do you accomplish this right now with AVI? As far as support goes, I'd say AVI is doing pretty well.. Even on set-op players... Now, believe it or not, coming up with a new system against the AVI mess, makes the situation WORSE, not better, because players would have to maintain multiple lists instead of one in order to support several formats. As for the actual list to put in the spec, for all I care you can grab the list from riff.c and use that. - ods15
