Hi Christian.
I haven't really tested these properly yet, but did find a small issue
with low strength denoise and mplayer.
-vo vdpau:denoise=0.1
vl/vl_median_filter.c:252:vl_median_filter_init: Assertion `size > 0
&& size < 20' failed.
0.2 and 0.3
tgsi/tgsi_ureg.c:891:ureg_emit_dst: Assertion `dst.File !=
TGSI_FILE_CONSTANT' failed.
0.4 and above are OK.
Hi Andy,
thanks for testing, unfortunately I only tested 0.5 and 1.0 strength.
Everything below 0.4 resulted in a median filter window of either zero
or one, and both values doesn't make any sense.
Patch to fix this is underway,
Christian.
