Can image data frames is shown at the rate of 30frames/sec, will it replace video. If so how?

[@info]

Actually I dont have camera to acquire video signal, while I have to work on video compression technique H.261. I just wanted to ask that if I dont have camera, can I use the image data frames at the rate of 30frames/sec to show like video or can you suggest any other alternative?.

What labview library supports video compression?

Any example of implemented technique of video compression if any one can suggest?

Thanks in anticipation

HI @info,

NI's Vision Acquisition driver software installs several VIs for working with AVI files, such as the IMAQ AVI Read Frame.  Can you create an AVI from the H.261 frames?

If so, you could download Vision Acquisition and try to use the Read AVI vi to play back the video.

IMAQ AVI Get Filter Names is a VI that finds the compatible AVI compression filters currently installed on the computer, which would be useful to be sure LabVIEW recognizes the H.261 codec.

Hopefully this information is helpful for you

Hi @info,

I would suggest you take a look at the Sequence and Save to AVI.vi example.  This can be found by searching the example finder for AVI.  From the sounds of it this example dose very close or exactly what you would like to do. As for the compression question I would suggest looking at the AVI Compressor Comparison.vi
