Live streaming to Android issues

[ChrisDotson]

My disclaimer is that I'm very new to Wowza. If the solution is staring me in the face, please forgive me.

I have a live stream running but my Moto Droid (Froyo) does not see the RTSP stream. It didn't work with 2.1 either. VLC plays the stream, though not well at times.

I'm running Wirecast pushing out both a RTMP stream as well as an RTSP stream. Neither work for the Android. VLC plays the RTSP and iPhone plays the other just fine. The only issue is my Droid.

I've opened all the ports on the firewall that I could find listed in the docs and on the forums. At one point, I could get the audio for the stream but not the video. I added the following code to my Applications.xml file, and now nothing on the Android side works. I get a "video cannot be played" error.

<Property>
<Name>forceMPEGTSOut</Name>
<Value>true</Value>
<Type>Boolean</Type>
</Property>
<Property>
<Name>rtpWrapMPEGTS</Name>
<Value>true</Value>
<Type>Boolean</Type>
</Property>

The link to the stream is: rtsp://jtvmedia1.acntv.com/live/mystream.sdp


Thanks!

I took out the code I mentioned in the above post. I am back to hearing the audio for the stream but not seeing any video.

Thanks for the reply, Richard. I have checked out that thread and many many others. What makes this particular problem strange is that I can play the stream (video and audio) with VLC. As it turns out, it even worked on Blackberry.

When I connect to the stream on my Droid, I only hear the audio.

This thread might have useful clues.

Many RTSP/RTP implementations of mobile devices only support RTSP/RTP over RTP. I believe Android is such a device. Not all carriers will allow UDP traffic on their networks. Also, there can be NAT traversal issues with UDP when streaming using WiFi. I would focus on UDP routing and NAT traversal as the issue that leads to RTSP/RTP failure. It does work. I have an Motorola Droid and it is able to stream RTSP/RTP. If the network is not setup properly or UDP is blocked, it will not work.

What I don't understand is why I get audio and not video on the Droid, but I get video on Blackberry and VLC.

They are different devices from different manufacturers, and most likely involving different carriers and networks.

Different devices, for certain, but both are on Verizon. I can play rtsp links from other providers on my Droid. If rtsp was blocked, I would think that I would not be able to play their content nor would I get the just the audio from my stream.

Does our sample stream play on the Droid:

I know it does on my Motorola Droid running 2.2. If it does, then it could be an encoding issue.

Yes, that plays just fine on my Droid. That example, plus others that work, tell me the port and carrier limitations are not an issue here. As I said, I can hear the audio in my stream, I just can't see the video.

Using Wirecast, I'm sending out an h.264 encoded video. I'm using one of the default Flash profiles but have lowered the bitrate to ~200kbps and 15fps. It works everywhere but on the Droid. Any pointers would be greatly appreciated, Charlie!

Thank you!
