Re: [Flashcoders] flv playback from DVD
Thanks for your ideas - I might jst a few frames of colour matte in the beginning fading up so that this is not an issue anymore. I also think that it's not a Zinc issue, as it even happens when I just play it out of Flash (Ctrl+Enter). We also have since discovered that the audio and video file from which the flv was taken are not exactly the same length in the original, so this may have an impact on this probhlem as well another problme I am having with this which is the stop event not firing properly (but that is another topic on this list ...

RE: [Flashcoders] flv playback from DVD
I had some problems with big videos on DVDs and Flash. On local videos, Flash don´t stream, and preloads don´t works. Then, the clients see an black screen after Flash loads a total video to play. My solution was take a Zinc, and work video width MediaPlayer6. The problem is that don´t support flv. I realy need to work with local streaming in Flash, but think this not happen!

Hi Rich, Going a bit off topic, but have you ever had a kind of hick up every time an flv starts playback.

[Flashcoders] flv playback from DVD
Hi
I am trying tro figurte out what the best way to play back flv's from
DVD would be?
At the moment I am using the following script:
var videoPath = mdm.Application.path+data/av/intro.flv
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
IntroClip_video.attachVideo (ns);
ns.play (videoPath);
ns.onStatus = function(info) {
trace(info.code);
if (info.code == NetStream.Play.Stop) {
gotoAndPlay(10);
}
};
...but I am not sure it is the best, as some videos never seem to
'finish' so that the application I am developing hands on the last
video frame instead of moving on to frame 10.
Would proper streaming be better, than progressive download?
Thanks!
Nik Crosina

Re: [Flashcoders] flv playback from DVD
Hi Rich, Thank you for attempting to answer a rather tentative post, I am finding out more as I am writing this - ... the main reason why I posted was because the video I got from the client didn't trigger the script that was supposed ot execute at the end of the video. Now it turns out that Flash 8 encoder doesn't do it's job properly when entering the metadata and I have found that Flix Pro does. Or at least in such a way that it triggers 'NetStream.Play.Stop' which is what I would assume is safest when determining whether a clip has finished playing back. The DVD is the distribution medium and I have done loads of these with Director, but not so many with Flash (probably going to change in the future though).
