2015-10-04avcodec: use HAVE_THREADS header guards to silence -Wunused-functionGanesh Ajjanagadde
When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions. This patch should silence such warnings. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

2015-06-09vp8: change mv_{min,max}.{x,y} type to intAndreas Cadhalpun
If one of the dimensions is larger than 8176, s->mb_width or s->mb_height is larger than 511, leading to an int16_t overflow of s->mv_max.{x,y}. This then causes av_clip to be called with amin > amax. Changing the type to int avoids the overflow and has no negative effect, because s->mv_max is only used in clamp_mv for clipping. Since mv_max.{x,y} is positive and mv_min.{x,y} negative, av_clip can't increase the absolute value. The input to av_clip is an int16_t, and thus the output fits into int16_t as well. For additional safety, s->mv_{min,max}.{x,y} are clipped to int16_t range before use. Reviewed-by: Ronald S.
