Can ipod streaming be done without an sdp file? For example could I use the stream name alias module to alias the following streams and play them through an ipod touch? The reason I ask is because that is what I'm trying to do and the wowza server log says it can't find the stream name's as files in the content folder.

aliasmap.stream.txt:
first=rtsp://userass@10.6.17.6/axis-media/media.amp
second=udp://@239.226.12.34:1234

This works great in flash with server = rtmp://wowza-server-ip/rtplive and stream = first or second.

This is what I'm trying in safari on an iPod touch with the wowza java file not found error:

http://wowza-server-ip:1935/rtplive/first/playlist.m3u8
http://wowza-server-ip:1935/rtplive/.../playlist.m3u8

Stream Manager shows they are streaming.

I guess I may not understand the difference between stream type live and rtplive?

The way to debug this is look at the log files and see when the stream map files are read and the how the alias is matched.

Hi Guys,

I would like to know, what VideoPlayer your are using on Android Phones, for test the RTSP Video in this device, I have 2 Android Phones, the HTC G1 and the new Motorola, but in both cases does not work, but if I try with VLC the stream work very well.

Thanks for any tips about this.
Regards,
Alejandro

I simply created an HTML web page with a link to the rtsp url. I opened the HTML page in the browser on the phone and clicked the link. The phone then played the stream in the media player. I have a Motorola Droid. I did most of my testing over WiFi. Be sure you have all the proper UDP ports open for streaming.

It is important that you are running the most recent version of Wowza.

Probably a silly question, but I wasn't sure so I thought I'd ask.

We have an origin and repeater setup working. The origin has video published to it by a simple browser based flash client, it's not going through any intermediary or encoding process.

The repeater just repeats these streams out and they're also consumed via a flash client through a standard website.

We now want to also consume the streams on the iPhone. We've setup the origin sever as:

liverepeater-origin
cupertinostreamingpacketizer, smoothstreamingpacketizer
cupertinostreaming, smoothstreaming
smoothStreamingMediaMajorVersion 2

and the child server as:
liverepeater-repeater
cupertinostreamingrepeater, smoothstreamingrepeater
cupertinostreaming, smoothstreaming
smoothStreamingMediaMajorVersion 2

In doing this, the normal web based video still works fine, but we get errors when attempting to push the iPhone/iPad stating:

LiveStreamPacketizerCupertino.handleHolder: Invalid video codec for iPhone/iPod: 2

My first thoughts are that because it's being viewed on an iPhone/iPad it needs to be h264 and my hope was that Wowza does this conversion for you. My thinking NOW is that Wowza doesn't do the conversion and we would need to actually encode before publishing. Is this correct or do you need more to go on to determine the error?

Thanks!

********** UPDATE: received a respone via email already. Thanks Richard!

Hi Charlie,

i am a newbie with wowza. i followed your tutorial, I tried playback with link for flashplayer with rtmp protocol work good, link for iphone, ipod touch with http protocol work good but when i tried playback with rtsp link, the real player and quicktime player show "switching transport", nothing else happen. I tried rtsp link with vlc it work.

I googled for "switching transport" on quicktime and real player, people said it because of firewall, i turned it off but still the same.

Do you have any idea to fix this?

Thanks and regard!

If you mean how to use one live stream to play on Flash and IPhone, then just follow the guide at the top of this thread.

If you mean you want two streams of different bitrate, then you have to publish two streams, Wowza will not create two streams from one.
