Frame order problem

alex2b · Post by **alex2b** » Fri May 20, 2005 3:24 am

I'm using 1.20.1, on fedora core 2, SMP system with 2 P-III 350
I have 1 camera connected via tv-tunuer board with bttv chip.
Frame params are 576x432, grey, max fps 25. I use modect mode.

When event is saved, frames are mixed.
For example, first go frames for time: 14:02:49-14:02:50, then 14:02:52-14:02:53, and then I have frame from 14:02:51 to the end of event with exclusion of 14:02:52-14:02:53.

What should I try to fix this?

I'm not sure I exactly understand what you are saying is wrong. Can you paste the frames tables from the web pages into here so I can see the timings.

Not sure what to paste to make it clear. Let me explain again.

Frame numbers are correct. But somewhere in the middle of frame sequence happens following:

frame 20: Catpured at 12:13:00
frame 21: Catpured at 12:13:02
frame 22: Catpured at 12:13:01

This is just an example, not real sequence. Do you get the problem?

I've got more info
I had ring buffer set to 50 frames and pre-event buffer to 30. May this cause the problem?

And more details about problem:
First i had 30 files from 001-capture.jpg to 030-capture.jpg, than 031-analyse.jpg and so on
And frames 001-capture.jpg to 030-capture.jpg were captured LATER than (031-analyse.jpg and on). But save BEFOR them
Now I've set buffer sizes to recommended values, will see if it helps.

Ok, now everything works fine

There was problem with wrong buffer settings.
Sorry.

I'm glad you got it working, though I still don't really understand why the problem occurred beforehand
