The problem is i unable to stream this kuraiamr_nb.mov file at my streaming server. when i play this file in quicktime player its stating that this is a unsupported media type.

What's wrong at my conversion?

Yess i got the point why i couldn't stream this file at my darwin server because after convert the file we need to hint this using mp4creator then only its become as streamable file.

But still i have problem with my scenario:-
i need a streamable audio or video file(darwin support format .3gp, .mp4 or .mov) with any of these g729, g726, g7211 or g723.1 codecs.

if anybody have idea please guide me to do this task.

Thanks.

I unable to find a opensource converter for these codecs (g729,g721,g723.1) because all these are licenses codecs. However if anybody have some streamable samples with these codecs please share with me.
