Just a quick question for those using viaslice output driver...
Are you seeing 'chunky' mpeg output?
I'm using a dvb-t card to supply an mpeg source stream but the playback
through viaslice is displaying, um, chunkyness.
Hard to describe... the effect is quite subtle, but the effect is like
there are vertical bars down the screen at eight pixel intervals. almoset
as if the Y shading across that patch is reversed. Quite subtle, but most
noticeable with light greys or greens.
The effect is particularly noticeable on a 4:3 video being played back in
vertical letterboxed mode... if the image pans than there mpeg corruption
on the extreme edges of the screen as new colours move in.
Initially I thought this may be some problem with scaling the image, but
throwing loads of debugging messages and using an output resolution of
720x576, shows no problems.
So, is anyone else seeing this?
