About NetStream.step backward frame not work? I created a stream connecting to FMS4.5 and is able to Smart Seek with setting inBufferSeek=true, detail's as below:ns=new NetStream(nc);ns.inBufferSeek=true;ns.backBufferTime=60;ns.bufferTime=3;ns.play("mp4:abc.f4v");it's ok to pause at 5's while playing fine. when i want to backward frame i use ns.step(-1); //workit works.however, when i firstly pause the stream and then seek to any time point, eg:ns.pause();......ns.seek(20);After recieving NetStream.Seek.Complete, when i tried to backward/forward frames, it does not work at all. eg:ns.step(-1); //not workns.step(1); //not workIf i run ns.resume(); ns.pause(); it was able to forward frames but not backwrad. eg:ns.pause();......ns.seek(20);......if(e.info.code=="NetStream.Seek.Complete"){ ns.resume(); ns.pause();}......ns.step(-1); //not workns.step(1); //workSo my question is, how to make it work to backward frames after that seeking has completed ?or, is there any possibility that this issue coul
