Can Wowza Stream this 3GP over RTSP?


We have a library of several thousands 3gp files that we currently stream using Helix Server. We want to use Wowza for all our VOD streaming (currently we use it for our flv web VOD streaming).

I’ve tried this link, but without any luck: rtsp://

Any idea? Is this format compatible or do I need to re-encode?

I don’t think this will work with Wowza. H.263 video and AMR audio are not supported.


Use h.264 video and AAC audio. MP3 audio might work too, but AAC is preferable. I would also use Baseline level 3 profile for the video, which is a requirement for iOS devices, but can’t hurt in this case.


Yes, that’s what you should use for mobile at this time.

Also take a look at Wowza specs page

And list of tested players

The above is not a complete list, but I don’t think Windows Mobile supported.


Thanks… is there a list of supported mobile formats by Wowza?

We currently have lots of traffic from Blackberry devices, so a format that work for those devices is important.


I also found this demo on wowza site and read the encoding details:

Here I have one Android device (Samsung Vibrant) and one Windows Mobile 6.5 device (Samsung Epix). I was able to playback both audio/video on the Android, but only audio on the Windows Mobile 6.5.

I’ll need to try other devices (specially BB) to see how it works. That is the only mobile encoding you currently support?
