[FFmpeg-devel] A very basic DCT question
Fri Sep 19 18:01:34 CEST 2008
I'm going to ask the most basic (perhaps even stupid) question
of all -- is there a way to hook DCT routines that do NOT
scale their output by a factor of 8x to dsputil properly?
I haven't touched that part of FFmpeg for at least 5 years,
but last time I did, I had an impression that it was
possible to tell DSPContext what scale factor was there.
And since we are on this subject: can someone, please,
provide a sufficient background for me to understand
where did this 8x scale factor come from to begin with?
Most of the DCT implementations I see around don't
have anything like that.
