Repeating HTTP stream?

Hello. I have some trouble with using wowza server right now.

At this moment, our company has one equipment which sends mpeg-ts streaming(I believe but I may wrong) to only one client.

I can use the url to connect from iphone or vlc.

But since this equipment only works with one client, I want to connect this with wowza server and broadcast to multiple clients.

I was able to connect to device by using such url:

http://10.1.1.1/stream.m3u

or

http://10.1.1.1/stream.ts

When I checked codec with VLC, it is H264/AAC.

I dont think I can setup the device to stream to wowza server. So my best luck is that I setup wowza server to fetch that address and restream.

I searched most of articles and tutorials and failed to find such example for me.

Thank you very much.

It may be possible, but you won’t be able to do it with the http URLs.

Would you provide more information on equipment you mentioned?

Perhaps there are other transports that the equipment can provide a stream on?

You want to either stream to a rtsp or udp address that you can re-stream (pull) from in Wowza, or publish (push) a RTMP or RTP stream to Wowza . Depending on which of those you can accomplish, follow the appropriate tutorial from this list:

Take a look at this article:

https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming

The main factors are key frame frequency and cupertinoChunkDurationTarget. The default is 10 seconds (10000 milliseconds), and a good key frame frequency is 2 seconds (a factor of 10, as noted in the article). You might have 1 second key frame frequency and 1 second cupertinoChunkDurationTarget for faster startup.

Shaun,

What type of stream is it? Wowza cannot re-stream San Jose or Cupertino HTTP. See the specs page for a list of Compatible Live Encoding that Wowza can injest: http://www.wowza.com/media-server#specifications

Do you know what type of stream/encoding the Akamai link is?

Thanks for the reply. Yes, Flash HTTP is San Jose which is not supported for ingest.

It may be possible, but you won’t be able to do it with the http URLs.

Would you provide more information on equipment you mentioned?

Thank you for your reply Daren.

I hope that I have more detailed ways to setup the device, however, I would like to describe the support of this device from the company is “shit”

However, I was able to manage login to the device and pulled main applications help.

Hopefully, theres way to connect with wowza with any of command over there.

I followed this tutorial to push MPEG-TS/RTP/UDP stream to wowza server.

However, there is a problem with iPhone.

When I see the stream with rtsp(VLC) or rtmp(JWPlayer), I dont see any problem so far.

But, when I see the stream with iPhone, there is a bit of delay at the beginning.

The delay of stream is about 30second slow.

However, after while, the delay gets increased and at the end of day, I was watching 1hour delayed stream (WOW!!!)

Is this natural? or am I missing something?

Thanks.

Hi daren_j

You say here that you can’t live repeat from HTTP URLs. It that right?

I just upgraded to the Akamai HD network and now have Flash delivered over HTTP instead of RTMP.

Example:

http://brightcove03-f.akamaihd.net/STREAM_001_1@XXXXX

Is it not possible to live repeat that stream with Wowza to HLS (m3u8)?

Please advise.

Thanks

Shaun

Hi Randall

It is a Flash stream over HTTP. I was using the regular Akamai server which used RTMP. But now that I’ve upgraded to Akamai HD the stream is delivered over HTTP.

Akamai example: http://brightcove03-f.akamaihd.net/STREAM_001_1@XXXXX

Akamai HD example: rtmp://cp101680.live.edgefcs.net/live/STREAM_001_1@XXXXX

Cheers

Shaun
