0050 for mp3..
I agree, random numeric twocc's for audio are an abomination.
Also first decide to use all-uppercase or all-lowercase, but dont mix
agree
On occasion there may be a reason to choose a specific case, but cases should not be mixed just randomly for the hell of it, for sure. I would prefer lowercase but it's not a big deal, and if historic usage is DOS UPPERCASE LAMENESS then perhaps we should just use it.
it. And I would just stick to all fourcc (4bytes) for audio aswell. I
agree
Agree strongly.
and may i suggest to do mpeg audio/video more consistant?
mpegX video "MXV",0 (M1V,M2V,M4V) AC3 "AC3",0 H26X "H26X"
Looks good. What about h263+? :)
mp3 "MP3",0
And "MP2",0 "MP1",0 ...?
and a generic suggestion that the file extension should be used as fourcc if theres a well known filename extension for the elementary stream and generic suggestion 2 if theres a well known avi fourcc then that should be used
These seem reasonable. Can we clarify that the "well known avi fourcc" should refer to the compression format and not a specific implementation name or marketing crap? Rich
