[Xerte] Controlling an flv

Tue Jan 4 14:13:08 GMT 2011

If I recall correctly:

Seeking depends on keyframes (I think). If you only have one keyframe, frame 1, then you cannot seek anywhere. If you have a keyframe every frame, your movie will be huge - but you can seek to any frame. When you encode .flv you should bear in mind how many keyframes you need.

Tell me if Christmas has addled my brain and I'm talking rubbish.

Hello

I have asked this question many times in various fora and the answer seems to be that the points only work with *real* streaming servers - otherwise cuepoints are essential. Don' t know if this helps, but I kind of despair with this as it is critical for the sorts of things I try to do. The only ray of sunshine in this scenario is to construct something with VLC which seems to work with both local and remote media (when it actually calculates the seekpoints correctly). I suspect it works because VCL is a streamer itself - not sure if it works with FLV files - it does work with mp4/mpg.

Hope this helps a bit - at least that is my experience of something I would love to be able to do.

Cheers

themovieid.seek(2) just doesn't seem to do boo.
Although it does trip an onMovieSeek event, which is supposed to mean it is finished seeking.

Tried stopping/pausing prior to calling it and nothing.
Tried putting it below a button to be sure the flv was loaded prior to call.
Tried removing the controls, no stream, etc.
Nothing.

Maybe the cue points are de rigeur?
e.g. won't do anything with a time index?
Anyone have it working with a time index?

Under the hood is the FLVPlayback component, which you can access directly if needed. The user controls just access what you can access, so I'm not sure it makes any odds: you might want to call stop() before seeking, not sure.

Use seek to jump to a particular point.

You can use addASCuePoint to set up an event at a particular point on the movie's timeline and handle onASCuePoint to pause / stop / reset the movie

Anyone have a template or hints on controlling which slice of an flv to show?

I have flvs that are used in multiple places, just using different segments.

Figure it uses seek and stop, but I'm sure I'll be re-inventing something, like when to determine it's OK to use seek, what's the effect if the clip is also under user control etc.

Happy New Year all!
