Tr : Difference between mp4mux and qtmux

[narcisse doudieu siewe]

sure they do the sames basic job but  the quicktime format can have some extensions that the mp4 does not
and vis versa. with mp4 you can sur decode correctly the video, audio an subtitle in the quicktime format but
you cannot see the others informations regarding only Quicktime, this extension will be ignored.

So to get all the options both standars option and extensions options in the case of Quicktime for example
you should use a qtdemux
for mp4 uses mp4

the MPEG4 standard define the basic that all implementions should take in count but also permits extension features
for a particular implementation 


Hi,

Can anyone tell me the difference between these two muxers? They pretty much
seem to do the same job
