Ip Camera Demo

[dlara]

hi, im trying to run latest version 2.47 with the IPCamera Demo(vlc and multidemo) but none of them works. This part

capture := cvCreateFileCapture(pAnsiChar(rtsp));
if Assigned(capture) then

always return capture = nil so never enter inside the if statment.
I have not previous version of Delphi-OpenCV so i cant test it. It seems to be a problem with the highgui library.

Thank you for your great work.

Regards

Edit: I found this function that could be of help for someone (http://casper123189.blogspot.com.es/2013/01/tbitmap2iplimage-iplimagetotbitmap.html) With this i can capture a snapshot thorugh indy+http and then put it into the correct pointer for opencv:

function TBitmap2IPLImage(srcBmp: TBitmap): PIplImage;
begin
Result := cvCreateImage(cvSize(srcBmp.Width, srcBmp.Height), IPL_DEPTH_8U,3);
Result.Origin := IPL_ORIGIN_BL;
CopyMemory(Result.ImageData, srcBmp.ScanLine[srcBmp.Height - 1],Result.ImageSize);
end;

Check the address to connect
Address must (can) contain the login and password, and port, for example:
rtsp://admin:admin@192.168.0.202:554/cam/realmonitor?channel=1&subtype=0

Some functions for bitmap images and their output are shown in cvUtils, such IplImage2Bitmap, cvImage2Bitmap, ipDraw.
I will write and test functions to convert back soon.

Thanks for your quick reply. I have tested it adding port (although is standard rtps 554), user/password not needed but same result, pointer always nil. I have not problem using VLC or TVideograbber. Anyway its not a great problem as can i use as i said before.

Thank you very much!

Although im not sure... there is a bug in opencv 247 wich could be the reason of the problem with ffmpeg:

Probably not.
