How do you play ISMV files with WMP? |
the ftyp box is the codec used (avc or h264),the track are only 2,one for the audio and the other for the video...all the data of the box moof and mdat must be simple copy and pastes in the ismv file...the other details i don't know,but i don't think is very difficult make the ismv file...maybe there is a detail that I don't consider,but i see that the details in the manifest file of release 1 are the same of the detail in the release 2...the only difference that i see is how are managed the chunk,when major version is 1:
<c
n="0"
d="20000000" />
<c
n="1"
d="20000000" />
the attribute d(duration) of the tag c(chunk) is constant while when the major version of the manifest file is 2 the chunk are managed in this way:
<c
t="509800000000" />
<c
t="509820000000" />
for the bitrate the attribute of the tag QualityLevel are the same...
did you work in the jaksta developer team?
for windows media player i don't remember how I have maked to enable the view of ismv file,if i find the decoder file(.ax or .dll) i send it to you...maybe the view is enalbed when i setup he microsoft encoder expression 3 pro,but i'm not sure...
