[REQUEST] aq_strenght & ratetol

[Benman2785]

hi,

to improve quality i would ask for:

aq_strength - could sharpen the image more - this would help alot (maybe needs chooseable aq_mode 0-2)

&

ratetol - can maintain better quality over time because it limits the max and minimun size difference of any single frame to a percentage of average bitrate - in combination with custom buffer it would maintain a "less spiky & overall good quality stream"

those two would help to maintain a better stream quality

aq_strength - codec team would like to know more about your target usage for better design considerations ratetol - We have MAX_AU_SIZE to control single frame size, playing together with VBV_BUFFER_SIZE & INITIAL_VBV_BUFFER_FULLNESS parameters, it could serve the purpose of output “less spiky & overall good quality stream”

for aq_strength as far as i know amf supports aq_mode 1 and 2; with aq_strength of 0.2-1,5 i could force a much more "clean-looking" image quality
