From c32e4029d99fb1bff3df86f62a3ce61d2419aae0 Mon Sep 17 00:00:00 2001 From: Janne Grunau Date: Wed, 21 Dec 2011 01:37:44 +0100 Subject: [PATCH] options: set minimum for "threads" to zero A negative number of threads does not make sense and 0 is used for autodetection. Adds a symbolic name for autodetection. --- libavcodec/options.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/libavcodec/options.c b/libavcodec/options.c index a3a102c0c8..4ac9313f27 100644 --- a/libavcodec/options.c +++ b/libavcodec/options.c @@ -370,7 +370,8 @@ static const AVOption options[]={ {"float", NULL, 0, AV_OPT_TYPE_CONST, {.dbl = FF_AA_FLOAT }, INT_MIN, INT_MAX, V|D, "aa"}, #endif {"qns", "quantizer noise shaping", OFFSET(quantizer_noise_shaping), AV_OPT_TYPE_INT, {.dbl = DEFAULT }, INT_MIN, INT_MAX, V|E}, -{"threads", NULL, OFFSET(thread_count), AV_OPT_TYPE_INT, {.dbl = 1 }, INT_MIN, INT_MAX, V|E|D}, +{"threads", NULL, OFFSET(thread_count), AV_OPT_TYPE_INT, {.dbl = 1 }, 0, INT_MAX, V|E|D, "threads"}, +{"auto", "detect a good number of threads", 0, AV_OPT_TYPE_CONST, {.dbl = 0 }, INT_MIN, INT_MAX, V|E|D, "threads"}, {"me_threshold", "motion estimaton threshold", OFFSET(me_threshold), AV_OPT_TYPE_INT, {.dbl = DEFAULT }, INT_MIN, INT_MAX, V|E}, {"mb_threshold", "macroblock threshold", OFFSET(mb_threshold), AV_OPT_TYPE_INT, {.dbl = DEFAULT }, INT_MIN, INT_MAX, V|E}, {"dc", "intra_dc_precision", OFFSET(intra_dc_precision), AV_OPT_TYPE_INT, {.dbl = 0 }, INT_MIN, INT_MAX, V|E},
