I have a problem with an java screen recorder. The problem is that the video and audio gets out of sync sometimes if the client computer is a bit slow.
The tecnique used is to capture a lot of jpegs and the sound. After that the jpegs is rendered to an quicktime movie along with the sound.
Do you guys know of a good tecnique to always get this in sync?
Can you record the system time of the sound recordings and screen captures so you can resync them when you generate the movie.
Thanks for the reply =)Quote:

Regarding the jpegs maybe I could make an array and save what milliseconds each frame should belong to, but does anyone have a clue how I could do to save the same metadata about the sound?
If you are saving the sound as a continuous stream and there's no time data captured in the stream then it's a little trickier.
I suppose you could monitor the number of bytes passed through the sound stream and save the total number of bytes at the point you capture each image and use that to resync the images to the sound.
Sounds like a good idea, thanks!Quote:
