    Default Differents aspect radio between Flash RTMP and Flash OSMF

    I'm restreaming an ip camera, wowza works really good!!!
    But i have a little problem with aspect radio. When using \examples\LiveVideoStreaming\client i got the original aspect radio (16:9), when using \examples\LiveVideoStreaming\clientOSMF or clientSilverlight (with Smooth Stream) i got a wrong aspect radio (like a 4:3)

    It's caused by a wrong configuration?

    An other question: it's possible to do live multi bit-rate re-stream for Smooth Stream / Silverlight?

    Hi
    Not sure if there is a wrong configuration on Wowza's part.
    Yes you can do live multi bit-rate re-stream for Smooth Stream / Silverlight,
    but you will need a smil file to do this.

    thank for quick reply i'll try multi-bitrate method

    for aspect radio problem: i noticed that clientFlex (that also use the same rtmp streaming of "client"), show incorrect aspect radio, so i think it's not a Wowza problem but a Live Video Players one

    I did quick test of clientOSMF and clientSilverlight examples that ship with Wowza 3, using a FMLE stream forced to a 16:9 ratio, and both displayed correctly.

    The IP camera may be missing frame size in metadata. The /client (Flash AS3) example doesn't use metadata to size the display. It waits for the video and uses actual frame size that the player detects.

    i checked settings and video stream info and i noticed that metadata is present and original stream video size is 1440x1080 (it was 1920x1080i on Axis camera settings, but i've done a little research and many ip camera record only 1440x1080 and stretch the video). I will try 1280x720p when i can stop my live recording, i think that i'll solve the problem, big thanks for pointing me in the right direction
