I need to display large number of streams in one flash player. In order to minimize cpu load i want to display only intra frames in h264 video. I have tired receiveVideoFPS method of netstream with value 1 and 2 but it is not giving the correct result.

In wowza server i tired recieveVideFPS with value -3 and it is giving the correct result as i want but after some time flash player crashes in all the browsers and in air too.

    Hi,

    I am not sure whether you can configure FMS to just deliver Intermediate frames but there are configurations which are the related to Intermediate frames.

    Please check <Live>/<AccumulatedIFrames> tag in Application.xml. Also you can turn off <EnhancedSeek> in Application.xml to false to see if that makes any difference at client-end for you.

    I am not sure about how Wowza does so can't comment anything there.

    But playing having lots of Flash Player's open on single machine is not ideal case, i would recommend spread it across different machines if possible.

    I know i have not answered your query the you wanted it. I will try to gather more info possible and let you know.

    Thankyou,

    I will try your suggestion today.

    My restriction is to use only one machine and display about 100 streams in one netconnection. I don't need to display the complete stream that's why i want to decode only intra frames and it consumes less cpu resources.

    In wowza i have tried intra mode and successfully displayed about 50 streams consuming about 30-40 % of 2 Ghz C2Duo processor.
