video recording from WEBCAM to AVI FILE

[KK_wong]

Dear Sir/Madam. i have problem with the recorded video from the webcam inside my LABVIEW.

whenever i record video, it speeds up towards the end and my file size is very big. it doesn't exactly record like a video. there's a timing problem.

i search in NI forum for quite sometime and the most closest VI to my current program is 'grab and save to AVI file imaq.'

it lags the computer considerably too. do you all know what may be the cause?

WEBCAM TO AVI FILE.

i attached the files in here. please help T.T

is there any other ways i can record or saving it in different format?

is there no one who can help me with this? T.T

You should separate the image acquisition and write to AVI into 2 parallel loops, so that the acquisition rate will not be limited by the write to AVI.

Use a queue to pass the images from one loop to the other.

i.e. use the standard producer/consumer design.

You will need an array of images for buffer, instead of just one image.
