View Full Version : total, utter failue : "avisynth has detected an exception ...."

Something has happened, and I don't know what. No changes to system or software, which consists of avisynth 2.52, decomb 4.10b, and mpeg2dec3 1.09, running on XP SP1, on a athlon palomino cpu.

ALL cce encodes that use multiple passes result in a .mpv full of "Avisynth has detected ...." error messages in all frames, from start to finish.

The .avs previews in vdub perfectly. It previews in cce perfectly.

While encoding, it's properly detecting bitrates and changing.

When finished, the .mpv is full of error frames. When you go into Bit Allocation, you have perfect preview video, and every single frame has a Q of 0.71 and the Q-factor is a flat line.

I've tried every single permutation I can think of software-wise upto and including a reformat and fresh windows installation.

Nothing seems to make this work.

And it gets weirder : the same problem occurs with tmpgenc *AND* procoder.

But if I use vdub to transcribe to a huffyuv file, it works fine.


CCE is 2.66.01.07, avisynth is 2.52, script is :

loadplugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Dec3.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\Decomb.dll")

Mpeg2Source("g:\input.d2v", iPP=true, idct=6)

Telecide(guide=1)

Decimate(cycle=5)

LanczosResize(720,480)

ConvertToYUY2()


the input is yv12, the output is converted to YUY2 to make it acceptable to the encoding programs.

anyone got any ideas?


thanks ...

"hmm, idct=6 doesnt work for me on an Athlon XP 2100+, it crashes avs with Unrecognised exception error"

Didn't affect me : I could load into vdub no problems, no errors.

But when I compressed with cce, the output file was full of frames containing the error message.

Upgraded cce to 2.67.01.11, switched to native yv12 frames, and updated mpeg2dec3.dll to v1.10 and it seems to be working better.

Still don't know what caused the original problems.
