Stored encoding settings (qpel,gmc etc) for XviD

[pernas]

Is there a tool or a way of finding out afterwards which settings (qpel, gmc, amount of b-vops, aq, etc) a Xvid clip were encoded with ?

With FFDShow, you can guess most of the settings, if you use its OSD / visualizations capabilities :
* QPel & GMC are shown by the frame type. With it, you can also know if B-frames were used, and also you can guess the max number of b-frames in a row was set.
* with visualizations, in quantizer mode, you can know if AQ was used ( if it is so, you should be able to find frames were quant aren't uniform )
* with the mean quantizer value, you can guess the b-frames settings.

The custom quant matrix should be stored somewhere in the file, but I don't know if there's a tool which can fetch it ( though I'm pretty sure the subject has already been brought up )

The settings you can't guess are : Chroma motion, Chroma optimizer, treillis, vhq, motion search precision, cartoon mode, and all the second pass settings.

Thanks, i've tried ffdshow and done some guessing ;) but...

Maybe i'm aiming to high (or sailing in the blue)....for me it would be easier if the settings used during encoding were stored / embedded
somewhere for verification / traceback / in case of future problems while playback on various devices :)

Periodical nagging:

We need a tool to extract the used quantization matrix out of the stream.
