Flash Player video only streams

[sivavenkatay]

Charlie,

Setting this value didn't seem to improve the frame-rate. This only happens when there is no audio in stream (either from the publisher or when the client says "receiveAudio(false)" ). However when I run wireshark, bitrate that is being delivered to the client doesn't drop. This happens irrespective of the codec. I am assuming you have a packet relay - transmission and when there are no audio packets you are relying on a timer to flush the packets - which is not working properly. What does surprise me is that the data rate doesn't change.

We are really stuck with this problem. I can confirm that red5 or FMS don't have this problem. Please advise.

Siva.

Charlie,

The flushInterval property seems to have no effect at all (no matter how much I put it). Is there something basic I could be missing?

I have wowza 1.7.2 and have a source and a reflector (I changed the property on both - and also tested with a single server with no luck) running as amazon ec2 instances.

If it works, it would be great for us. I can give you a test client to reproduce this if you want. Please let me know what I should do.

Thanks
Siva.

Be sure you are running the most recent patch for 1.7.2.

Be sure this setting is in the Streams/Properties.

The patch plus this property are the best we have.

Thanks. I will see if I am running the latest patch.

But did you find this issue before and was addressed or I am just trying out my luck ?

Just trying for luck.

Charlie,

Thanks! I applied the patch and it looked much better. However, when we have a reflector added to the same source (reflector is also patched up and the property set), the behavior on framerate is still bad. I think the flushInterval might be accruing in this case. Do you think there would be serious problems if I change it to 10 (like CPU)?

I see a variable in the conf file something like "MaximumPendingWriteBytes", would it have any effect?

Is there a better way to take care of this server side buffering of packets, will Wowza server 2 help?

Siva.

I tried setting up 15 instead of 25 on the source server and it doesn't seem to improve much. I am not sure how much I should push though. There must be a better way to do this than to rely on a timer.
