How do I find the BITMAPINFOHEADER of a image
-
Hi Im using AVIStreamWrite to create a video using a string of JPG's from a ethernet camera. I believe that I have to use aviSetFormat before I can use the above function. One of the arguments for the aviSetFormat function is a BITMAPINFOHEADER. I have tried settings it up manually but the video is just black. So is there a way of finding the BITMAPINFOHEADER of a image using a function call? Thanks

There is some code here[^] that does what you are trying to do. Have a look to see if it helps.

Thank you for the reply. I have managed to get it to create avi's with uncompressed images but my problem is that I dont know how to add compressed images. I need to know the BITMAPINFOHEADER.Compressed parameter. Do you know how I can get this parameter from the image? Thanks

According to A Simple C# Wrapper for the AviFile Library[^] you cannot add compressed images directly. It seems that you have to create a new
Streamadd them to that, then add the new stream. Anyway the article explains it better than I can. Although, from a very quick read, it does not seem to useBITMAPINFOHEADER.Compressedit seems to manage the whole thing. Once again, I hope that if it is not sufficient by itself, that it gives you some ideas.Henry Minute Do not read medical books!
