It did give me opportunity to see how eg GamMac should cope with some stuff, defo gonna update that.
EDIT: and if lord Pinterf were to correct and up for 16 bit, then would include such improvements also.
[ I pretty much understand Avs levels now,although my strange autogamma thing posted (but now delteted)
let me now understand some stuff, was real problem trying to work out autogamma script prob, I thought
I had GetFrame() recursive probs, was most confused.]

Oops, bugfix version AutoLevels v0.8 update (avs v2.58, avs/+ v2.6 x86 & x64)
8 Bit only.
Req VS 2008 Runtimes.
Includes 3 dll's, + source + Full VS2008 project files for easy rebuild.
See HOSTED directory @ MediaFire in sig below this post.

Bugfix:- Only scanned left half of YUY2 frame, fixed.
Also, made small mod to avoid overflow of accumulator on big (~ 8 million+ high value luma pixels) frames.

BugFix 1:
Code:
void Autolevels::GetAvgLumaYUY2(PVideoFrame &frame, int *yhisto)
{
    const int src_pitch = frame->GetPitch();
    const BYTE *srcp  = (BYTE *)frame->GetReadPtr(PLANAR_Y) + (src_pitch * border_t) + (2*border_l);
    const int ylim = vi.height - border_t - border_b;
    const int xlim = (vi.width  - border_l - border_r) * 2;   # Multiply by 2 [1 Luma sample + 1 Chroma]
    for (int y=ylim; --y>=0;) {
        for (int x=xlim; (x-=2)>=0;) {
            yhisto[srcp[x]]++;
        }
        srcp += src_pitch;
    }
}

Mod 2:
Code:
    __int64 wsum   = 0;    # Was int
    int     pixcnt = 0;
    // compute the mean from the histogram
    for(int bkt=ymininner; bkt <= ymaxinner; bkt++) {
    	pixcnt += yhisto[bkt];
    	wsum   += yhisto[bkt] * bkt;
    }
    mean = (double)wsum / (double)pixcnt;
    DPRINTF("getStats wsum=%I64d pixcnt=%d mean=%f",wsum,pixcnt,mean)

Oops again, Ver$ AutoLevels v0.9 update (avs v2.58, avs/+ v2.6 x86 & x64)
8 Bit only.
Req VS 2008 Runtimes.
Includes 3 dll's, + source + Full VS2008 project files for easy rebuild.
See HOSTED directory @ MediaFire in sig below this post.

Left debugging switch on, below should have been commented out for release, fixed. Probably was a bit slower than necessary.
Code:
#define BUG					// Uncomment to enable DPRINTF() output

EDIT: Created new thread in Usage forum( AutoLevels v0.9 ) :- http://forum.doom9.org/showthread.ph...17#post1876317
