advance frame-by-frame on a streaming video in flash

Wowza Streaming Engine
1

hi,

i’m new to the world of streaming video. i’ve recently installed Wowza media server 2 locally, currently only for testing purposes. i’m using my flash video-player to run the ‘sample.mp4’ file provided with the media server (in the ‘content’ folder), and everything works fine, except of accurate seeking functionality - or in other words advancing frame-by-frame.

when i use VLC to play my video file i have no problems advancing frame-by-frame. however, when i use the ‘seek()’ function to move the playhead a fraction of a second, its seems to move only to the next key frame (meaning that only once every few mouse clicks the playhead advances dramatically).

i thought that when using streaming video (unlike progressive download) this issue is resolved. am i wrong? did i miss something?

thanks in advance,

eRez

Have a look at https://www.wowza.com/docs/how-to-configure-trickplay-for-flash-vp6-or-spark-content

Also, if you set the following property in your Application.xml Streams/Properties section then you will be able to seek to any position.

	<Property>
		<Name>seekTarget</Name>
		<!-- valid values are: videoKeyFrame, audio, enhanced //DEFAULT = videoKeyFrame -->
		<Value>enhanced</Value>
	</Property>
