I420ToNV21 passes wrong dst_y stride #547

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
I420ToNV21 passes the wrong dst_stride_y when it calls I420ToNV12; parameter 8 
(convert_from.cc:448) is src_stride_y but should be dst_stride_y.  This causes 
image corruption when converting I420 -> NV21 with mismatched luminance strides.

Fix I420ToNV21 for wrong dst_stride_y parameter.

I420ToNV21 passes the wrong dst_stride_y when it calls I420ToNV12; parameter 8 
(convert_from.cc:448) is src_stride_y but should be dst_stride_y.  This causes
