No changes have been made to the Dirac-research codec since the 1.0.2 release. You are probably confusing it with the Schroedinger-1.0.8 release.

Hi everyone, the latest release of Dirac on Sourceforge that has Win32 Visual Studio support is 1.0.2, is there any hope in having a 1.0.8 version here? I see that no updates have been made since 1.0.2
thanks!

setstdiomode.cpp is broken: first it says "namespace dirac_vu", and then it conditionally includes some C headers. AFAIK it's a bad idea to include headers within namespace, unless you want all the respective functions to go into your namespace. Which is what happens at the moment. And that results in _fileno() becoming an undefined symbol at link-time.
Patch attached.

OK, done. Script file and source image bmp plus compressed and decompressed images emailed.

Please email them to asuraparaju at users dot sourceforge dot net. It will get forwarded to the address I'm currently using with sourceforge.

Anuradha, Hi,
I could e-mail you some, zipped up.
I am sure it must be my finger trouble,
because I tried the Jasper J2K codec on the images. It was fine.
Do you have a e-mail address?.

Is there a way that I can download a couple of images (.yuv) that you are using for running my own tests?.

I have run the encoder with DD9_7 LEGALL5_3 DD13_7 HAAR0 HAAR1 FIDELITY DAUB9_7 filter settings. There still seems to be a problem.
For example,
I see this with my colour bars image, even at high qualities. Looking at the PSNR figures, it is always in the luma. It is a "dark smudge" effect, at the abrupt vertical transition between my "left-to-right" colour bars in top...

.bmp's:
I have been using the image preparation tools to convert my .bmps to .rgb and then to .yuv and vice-versa to view the locally-decoded file, per the README file. I know this works because I convert the resulting .yuv back to .rgb and back to .bmp so that I can see the .yuv that is being given to the dirac_encoder.
-num_L1:
I tried setting "-num_L1 0", this did set the dirac...

Dirac does not read bitmap files. You need to convert to planar YUV using the conversion program in the util/conversion folder, or use e.g. ImageMagick.
If you're doing single frames, there is no need to change any of the inter coding elements. If you want to intra code a number of frames concatenated together, you need to set
-num_L1 0
You might not get the best results with DAUB_97...
