Hi all,
There's a quick and a easy way to see if mismatches or DCT implementation
Problems are *really* the cause of the issues seen.
Next time you see the Problem run the encoding again with either reference
inverse quantizer or iDCT routines.
This is really easy to do: simply put
calls->piquant_non_intra = iquant_non_intra_m2;
right at the end of the 'init_quantizer' function in quantize_ref.c
or
pidct = idct;
at the end of the 'init_transform' function in transfrm_ref.c
If the artefacts disappear we're getting a *lot* closer to finding the culprit
;-)
cheers,
Andrew
