	NetStream.play() by Dan Daemon-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hello guys, Does RED5 supports NetStream.play() with seek parameters? As you know it's possible to call play with second parameter which is bigger than 0 and means seeks from recorded stream. Does RED5 supports it? _______________________________________________ Red5 mailing list Red5@... http://osflash.org/mailman/listinfo/red5_osflash.org

Tip ; if you create movies yourself you want to add navigational cuepoints if you need to seek to a very precise keyframe. Else your encoding software will add keyframes once every 15-30 frames (depends on the encoder settings) and then you'd only be able to jump to one of those keyframes. Depending on the framerate you'd see a default accuracy of around 0.5 to 1 seconds in each video out of the box. W. ----- Original Message ----- From: dan.daemon@... To: Red5@...

	Re: NetStream.play() by Dan Daemon-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hello Walter, Thank you very much for your answer. So, if RED5 records my stream from my webcam I will be able to do something like nc.play( "my-stream-name", 500 ); right? Simple I tried but without results... should I generate cuepoints file or something else to get ability to seek? On Fri, Nov 6, 2009 at 2:49 AM, Walter Tak <walter@...> wrote: Ofcourse.

Learn more about Nabble's security policy. Yep even recorded webcam streams can be scrubbed but it's flaky because the framerate of recorded streams varies (!) ; it works like Variable BitRate (VBR) in MP3 soundfiles. Fortunately you can set the amount of keyframes going out with ; http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/media/Camera.html#setKeyFrameInterval%28%29 quote: Conversely, specifying a lower value for `keyFrameInterval` (sending keyframes more frequently) increases bandwidth use because entire video frames are transmitted more often, but may decrease the amount of time required to seek a particular video frame within a recorded video.
