Thank you for your question.

Yes, that's possible.

As you probably know, you should use a SWF movie with FLV player inside to play FLV. Such movie contains actionscript code like that:

Code: Select all

var netConn:NetConnection = new NetConnection();
netConn.connect(null);
var netStream:NetStream = new NetStream(netConn);
my_video.attachVideo(netStream);


To play:

Code: Select all

_root.netStream.play(url);


To get current time position of video:

Code: Select all

_root.netStream.time;


I've uploaded the movie.

SWF:

How to use.

You load the SWF. After that you provide a FLV URL:

Code: Select all

flashplayercontrol1.SetVariable('flv_url', '...URL here...');


To get current time position you call something like that:

Code: Select all

   CurPos: Integer;
...
   CurPos := StrToInt(flashplayercontrol1.GetVariable('flv_current_time'));


Get CurPos periodically (use TTimer, for example) each... for example, 500 ms. If 5 (for example!) times, you receive the same value -- it seems that FLV reaches the end.

Hello,

This is an interesting topic. I have a followup question on this:

I got the flv to work this way (thus called from the swf), but
now I can only get the current time of the flv, I actually want the current frame AND the total number of frames of the flv, so I can compare those 2 to detect of the flv has ended.

Is this possible? How?


Also other question:
Is it also possible to play / stream a flv immediately (instead of loading it in memory) because if I use big flv files, the loading takes too long. I actually want it to stream / play immediately, also on slow computers.


Thanks in advance,
Martin

I don't know a simple way. The only way is to parse the file, get timestamps for each frame. Why you don't like the way when you periodically test current time position?

Yes, of course, just pass the path / URL of a FLV:

Code: Select all

flashplayercontrol1.SetVariable('flv_url', '...URL here...');


You can also provide flv content from memory piece-by-piece, so that's not a problem: the playing starts immediately in this case too.

If I only know the current time of the movie (and not the total time of the movie) then I still dont know if the movie is at its end.

I have to know either the current time and the total time of the movie or (preferable) the current frame and total number of frames of the movie.

Yes, total time is unknown. Not sure but total time could be located in metadata.

But you still can monitor the current time position.

Hi, I am trying to read time as suggested with GetVariable('flv_current_time') using the SWF as you provided.

However, I get "unspecified error" when try to read the variable.
I do not have Flash program but with hex viewer I can see that flv_current_time is defined in the flash, so I am using the correct SWF.

Do you have any suggestions please? Thanks!

Thank you for your question.

Are you sure that you use this new SWF? If you load this SWF from resource, you should rebuild .res file and then rebuild the project.
