I would like to save the first frame of an flv movie as a png or jpg and I want to do it from a Flash swf. Is this possible? Thanks.

I saw that post and it isn't quite what I had in mind. What I am trying to do is create a flv uploader that will also automatically generate a thumbnail of the flv. The swf will be on a remote server so most third party programs will not work for me.

why won't work? can't you run external app on your server?

ffmpeg works on linux and also on windows machines and is a command line utility.

I got your taste,

apply following Logic:

the_nc = new NetConnection();
the_nc.connnect("rtmp path");

onSuccessfulNcConnect()
{
     in_nc = new NetStream(the_nc);
     in_nc.play(_root.flv, 1, 1);  // play flv starting from 1 second and play for 1 second (sorry if i applied any wrong syntax but thats the logic)
}

onNetStreamEnd() // when netstream finish to play the flv
{
     the_nc.close();  // to save # of connections on the server
}

attach all these code into one swf which you can host on your own server. name it like thumbnail.swf

call it like thumbnail.swf?flv=abc.flv

hope this helps.

I see. So instead of saving it as a thumbnail, this would actually show it in a paused state which would be the same as a thumbnail. That is smart. Would it take a long time to load if I have say 20 16MB flvs showing on the same page? Thanks for the help.
