Dear Group,
I have just started using your mpeg4tool from enst which is very useful
indeed.
http://www.comelec.enst.fr/~dufourd/mpeg-4/tools.html
I have a question regarding including audio and video streams in an mpeg4
scene.
Could you send me some example streams with the info files etc that are
needed
by the V2 policy?
I understand from below that I will need 3 files for each media stream:
>>For each raw elementary stream called stream.type, two files are expected:
>>
>>stream.info: contains the decoder specific info, a.k.a. the headers
>>stream.nhnt: contains the description of the access units in contained in
stream.type.
I am not sure how to create files like this. Do you have anymore information
on this
or could you point me to some tools for parsing? (The enst site is
mentioning some CSELT tools for
the V1 policy)
I basically want to encode my own video and audio files and use the mp4tool
from enst to create
mp4 files that have these streams included in the scenes.
Thanks very much.
