FILE3D="c:\Prj\IntelMedia\_testing\PANY.m2ts"

FRIMSource(codec="mvc", filename=FILE3D, filename_dep=FILE3D, container="ts", platform="sw", \
              layout="SBS", cache=24, reload=true, num_frames=350, log_file="c:\Prj\IntelMedia\_testing\Z1.log")
i.e. in SW mode - and without any issues.
Seems that something is wrong in your environment setting. (path or whatever)
As I indicated, the dll is in the path, in windows\system32. Anything else I could check on?

I don't know where the above mentioned quote is coming from, neither what were the conditions for its measurement.
Please keep on mind that that also disk access (2x 3 MB per each frame) takes its cost. Working on SSD is visibly faster.
3 fps in Full HD3D in -u 1 might be realistic.
(You can check -u 7 and compare)
The quote is from the top of the thread on MVCEnc. In that thread, they gave a solution to the performance problem: activate Intel drivers by faking a display . Which I did and Intel Media SDK System Analyzer showed HW supported afterwards (before this procedure, it showed only SW was supported - even though FRIMSource was working only in HW mode!). Now, I am getting 40 fps at -u 1 (just slightly faster, 42 fps at -u 3)! The files are read from a fast enterprise-grade drive (file transfers are usually above 120 MB/s sustained) and written to a Samsung pro SSD - so the IO is fine.
I think I can do without SW working at this point. Nonetheless, I will try to do more tests, run dependency walker, etc.

PS. I have tried MVCenc on the same setup, with the same full HD3D, and got 60 fps, exactly as they claim. MVCEnc ran in HW mode and reported SW as unavailable.
