Hi,

> 	(Michael, perhaps you could explain to me why avc_ctx->quality = 1 produces

as dct coeffs with qscale=1 are out or allowed mpeg1 range and thus they
will be clipped, producing _very_ bad quality images.

we should workaroundthis. librte had a trick, it checked coeffs range
_before_ quantization, and if all values were small, it used qscale=1,
otherwise qscale=2. so it got better quality using a bit more cpu.

it must be bug in _your_ code, as libavcodec don't know about seeking at
all, so seeking shouldn't break it...
probably another dxr3 seeking/pts bug
