Hi Sanath,

No, there wont be any problems by enabling this flag.
If you have enabled server side rate adaptation by enabling the config \
ServerSideRateControl=1, then even if the server does not support rate adaptation, it \
will not switch back to client side adaptation, it will still honor the server side \
rate control setting.

Thanks,
Jyotsana

Hi Jyotsana,

 Thanks for the suggestion. What you suggested does work fine. But enabling this in \
config file, what would happen if Server side does not support rate adaptation, then \
would it switch back to the old behavior, of client sending “SetDeliveryBandwidth \
parameters” which is like client side rate adaptation.

In short, if there are any possible problems that we could face by enabling this \
flag.

Thanks in Advance,
 Sanath.

Hi Manjunath,

SetDeliveryBandwidth is a client-side rate adaptation mechanism which is used to \
change the speed at which the server sends data depending on the amount of data that \
the client has. It is used to speed up or slow down the server depending on whether \
the client is running low on data or is accumulating data beyond what it needs. Do \
you see the client getting sufficient data before it sends the teardown request to \
end the session?

Usually the server-side rate adaptation is used (enabled by setting \
ServerSideRateControl=1 preference). It includes Helix-Adaptation and \
3gpp-adaptation. If server-side rate adaptation is enabled, the client side rate \
control will not take effect (SetDeliveryBandwidth parameters will not be sent). You \
might want to give this a try.

Thanks,
Jyotsana

Subject: RTSP :: Play of a streaming content often drops

Hi,

Play a streaming content from a specified server, initially streaming starts playing \
normally and it is fine, after few seconds the stream drops.

> From the IP logs it shows that the Client sends TEARDOWN method to the server. \
> Before sending the TEARDOWN command the client sends several SET_PARAMETER
methods to set the bandwidth(SetDeliveryBandwidth: Bandwidth) by increasing bandwidth \
in each SET_PARAMETER method then after several requests the client sends TEARDOWN \
method and the streaming gets dropped.

IP Log attached for more info.

is it really a bandwidth problem ??

Can anyone please help me in resolving this issue.

thanks in advance.

Best regards,
Manjunath
