Hi,

Corresponding with Flow player tutorial [http://flash.flowplayer.org/plugins/streaming/slowmotion.html](http://flash.flowplayer.org/plugins/streaming/slowmotion.html)

**Note: Wowza offers this feature only for FLV-encoded videos.**

I have video recorded into **flv** container by WowzaMedia Server.

When I try to change playback speed my video freezes.

I have to implement trick play for VOD only.

Any ideas appreciated.

What video codec is contained in the flv? If it is h.264, that might not work. I think it has to be Spark or VP6.

I am not sure how well Flowplayer implements trick play. Wowza’s trick play example player has been deprecated because of movement away from Spark and VP6

Sam,

Trick play didn’t worked in my tests with SmoothStreamMediaElement and Wowza smoothstreaming, but that was a couple of years ago.

H.264

For VOD it’s “must to have” feature.

What can you recommend to do?

Silverlight?

Ok.🙂

MS Silverlight **SmoothStreamingMediaElement**  **does** supports play rate switch (FF/FR).

With the given range:

-8.0, -4.0, 0.5, 1, 4.0, 8.0.

Thanks a lot
