NetStream.Buffer.Empty?

[Guest]

dvrcast is a live service.
mp4: as the service record and I look over to the dvr sample player debug output messages while out NetStream.Buffer.Empty will stop.

Screenshot is shown below.

Is it possible to do without stopping the service?

Hi,

Thanks for using DVRCast.

The service as such did not stop when the Buffer Empty message is returned. What it meant is that the buffer capacity of video has been emptied and there is nothing to play anymore. So, changing little the client buffer settings would make sure the buffer is full always and never gets emptied. If you are using the default buffer values, change them according to your workflow. Whatever values i have seen go in the range 3-6 sec. You need to also make sure of the bandwidth limitations of your client-server connections, if its an internal org workflow, make sure you have sufficient bandwidth.

Please let us know if that helped. Thank you !

Sorry service does not stop. play is stopped.

FMS configuration changes in the way Do not solve?

[Nikhil_Kalyan]

There are few FMS configurations also that you can take a look at :

Application.xml : MsgQueue settings.

Application.xml : AggregateMessage settings

Application.xml : Client and server bandwidth settings.

Server.xml : FLVCache settings

Server.xml : Mp4 video/audio/buffer settings.

You can find the application.xml under FMS installation\conf\_default_root\_default_vhost\

ORIGIN, EDGE Do I need to change both?

Or do I need to change the ORIGIN?

[Nikhil_Kalyan]

You need to change at the origin.

When I change the origin, as shown below, As the play NetStream.Buffer.Empty output stops.

Application.xml : MsgQueue settings.

<MinBufferTime>5000</MinBufferTime>

Application.xml : AggregateMessage settings

<AggregateMessages enabled="false"></AggregateMessages>

Application.xml : Client and server bandwidth settings.

default

Server.xml : FLVCache settings

default

Server.xml : Mp4 video/audio/buffer settings.

<VideoAutoBufferReadSize>1536000</VideoAutoBufferReadSize>
<AudioAutoBufferReadSize>512000</AudioAutoBufferReadSize>
<OtherAutoBufferReadSize>10240</OtherAutoBufferReadSize>

We will have configured the following:
