2017-11-27avcodec/nvdec: Implement vp8 hwaccelPhilip Langdale
2017-11-27vaapi: Add VP8 decode hwaccelMark Thompson
2017-11-27vp8: Add hwaccel hooksMark Thompson
Also adds some extra fields to the main context structure that may be needed by a hwaccel decoder. The current behaviour of the WebP decoder is maintained by adding an additional field to the VP8 decoder private context to indicate that it is actually being used as WebP (no hwaccel is supported for that case).

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.
