Live-Lowlatency with JW Player = Delay increasing over time. Please Help!

Wowza Streaming Engine

Pedro,

Still sounds like bitrate vs bandwith. I know you are down to 300kbs but it might still be too high.

Try the BWCheck example to get an actual look at the bandwidth between Wowza and the client that you are testing with. It’s in the examples folder.

See what BWCheck reports.

Pedro,

Take a look at this version which measures from client to Wowza:

Pedro,

Stick with the standard BWCheck. That’s what makes the most sense.

Richard

I can add this to the Modules collection.

I added it to collection:

Do you have Flash CS or Flash Builder? You need that to create the client part. the actionscript is in that post. I’ll see about doing it but not sure when.

Richard

#12

The client-side in that example is AS2, so I am having to dust-off my AS2 > AS3 skill set, which got a little rusty.

Richard

#13

That does look helpful. Buried on page 9. Thanks.

Pedro,

I added a Flex 4 client for the client to server BW check example. The source is added to the article

A built version can be downloaded here

Richard

#15

I added a ColumnChart to track and compare tests.

You are loading the other BWCheck somehow. There is no onBWDone in this one (some of the code snips have placeholders for it but were vestigial). Use the collection jar and the exact Module in this post:

https://www.wowza.com/docs/how-to-check-bandwidth-from-client-to-server-to-test-uplink-to-be-used-by-a-live-stream-encoder-moduleclientbwcheck)

<Module>
	<Name>ClientBWCheck</Name>
	<Description>ClientBWCheck</Description>
	<Class>com.wowza.wms.plugin.collection.module.ModuleClientBWCheck</Class>
</Module>

I named the application “upbwchecK”

Richard

Remember to restart Wowza after copying the collection jar to your Wowza lib folder.

Richard

#18

For each computer you want to use this on you have to copy the jar file from the module collection:

https://www.wowza.com/docs/utility-modules-for-wowza-streaming-engine-media-server-software

To the Wowza lib folder, and restart Wowza.

Then create a new application (I named mine “upbwcheck”, and and add the Module to the new Application.xml. I’m sure you will get it going.

Richard

Take a look at your access and error logs

Pedro,

I had hard-coded netconnection.connect using localhost instead of using TextInput. I updated and replaced the built version.

Sounds like you got it going in Flex anyway.

Changing to “live” only increases the delay. “live-lowlatency” is desing to reduce the delay, something that I could achieve, but by some reason the player doesn’t sustain that for long.

#22

I did… I’m sending at 300kbps which is way lower than what I need (700 or more)

It’s weird because at the beginning it looks just fine, than after 5 minutes it’s on 3 sec delay and it keep rising over time, but when I stop and play it goes back to normal.

#23

I was wrong, it’s not the player. I’ve tried with another player (moyea FLV player for windows) and the problem persist. When I start the broadcast I got very low latency, after a few minutes it goes up.

I’ve also tried running wowza from another machine (my macpro 8 core), got the same problem.

Must be some settings on wowza… does anyone know why is this happening?

thank you.

Hi Charlie. If I try to do this, the video gets choppy, it doesn’t play smooth.
