Question by Silas Silva · Nov 17, 2011 at 06:23 AM ·

No show ngrp:[stream-name]_all using Wowza Transcoder

I follow this tutorial: http://www.wowza.com/forums/showthread.php?13271-Wowza-Server-3-Preview-How-to-setup-and-run-live-stream-transcoder

But i dont see the group ngrp:[stream-name]_all, i see this on connectioncounts:

[stream-name]_360p

[stream-name]_240p

[stream-name]_160p

[stream-name]_source

Where is [stream-name]_all to run on iOS ? Another question, using groups Wowza deliver stream with multi-birate automatically ?

Tks,
Comment

Yes, [stream_name]_all is delivered as multi-bitrate. It won't show up in connectioncounts though.

The playlist is empty. Either your application is configured for Cupertino streaming, or the stream is not live, or you have not started it in StreamManager (if is is a MediaCaster stream)

Check step 3c:

http://www.wowza.com/forums/content.php?304-How-to-setup-and-run-Wowza-Transcoder

If the stream is MediaCaster source, IP camera or mpegts encoder for example, start in StreamManager

The correct Address is http://flashserverbr.com:1935/silas/ngrp:livestream_all/playlist.m3u8

I can watch using rtsp://flashserverbr.com:1935/live/livestream_160p

In the rtmp rendition, change "file=ngrp:livestream" to "file=livestream"

In iOS (IPhone 3gs iOS 5.01), I get prolonged loading screen, no errors but no video.

I fix this issue!

Just add

Set the Streams/LiveStreamPacketizers property to: cupertinostreamingpacketizer, smoothstreamingpacketizer, sanjosestreamingpacketizer:

Code:

<LiveStreamPacketizers>cupertinostreamingpacketizer, smoothstreamingpacketizer, sanjosestreamingpacketizer</LiveStreamPacketizers>

There is a way to use multi-bitrate on Android Devices ? Using StreamGroups ?
