Latency in ipad device while playing the url obtained from wowza streaming engine
As you said, I have changed keyframe interval of 1 frame per second to lower the cupertinoChunkDurationTarget to 1 second(1000) and get the latency down to closer to 3 seconds. But still the same latency i.e.more than 30 seconds is there. I restarted the system also .
Here are the details modified in application.xml
Here are my encoder setting details. Please help me to reduce the latency. Iam using adobe flash media live encoder for publishing into wowza.
Frame rate: 30 fps
Keyframe frequecy: 1 second
Bit rate: 650 kbps
Please help me to do any corrections for reducing latency while playing the wowza url in devices.
Please double check that you have entered these properties at the right location of the Application.xml file, the should be added to the
Are you referring to start time or latency, or both? Start time is how long it takes for a user to start seeing video after starting playback. Latency is how far behind the stream is compared to the encoder.
If you start Wowza in stand-alone mode [install-dir]/bin/startup.bat|.sh, you should see lines in the console like this. Please post what you see for these lines:
How are you testing? Is it local or remote, is it iOS device or HLS desktop playback with JW Player or VLC?
You can reduce the bitrate of the stream. You can remove network factors if you are testing remote to see what the delay is without that. Understand that iOS devices need 3 chunks before playback, so if the bitrate is very high and the device is remote and a slower connection, it still has to download 3 large chunks.
