Comment (by ponpon):
Replying to [comment:17 ubitux]:
i think the default value is too strong for SD video and slow for HD.
i try to change them in source from
{{{
static const AVOption nlmeans_options[] = {
{ "s", "denoising strength", OFFSET(sigma), AV_OPT_TYPE_DOUBLE, {
.dbl = 1.0 }, 1.0, 30.0, FLAGS },
{ "r", "research window", OFFSET(research_size),
AV_OPT_TYPE_INT, { .i64 = 7*2+1 }, 0, 99, FLAGS },
}}}
to
{{{
static const AVOption nlmeans_options[] = {
{ "s", "denoising strength", OFFSET(sigma), AV_OPT_TYPE_DOUBLE, {
.dbl = 0.85 }, 0.000001, 30.0, FLAGS },
{ "r", "research window", OFFSET(research_size),
AV_OPT_TYPE_INT, { .i64 = 3*2+1 }, 0, 99, FLAGS },
}}}
doesn't this brake the work of nlmeans?
is support for SIMD completed?
i have requests for nlmeans. should i write them here or open a new
ticket?
