From 05b0337025f629d0a6c6321147f06d0da5e32a62 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Fri, 19 Oct 2012 01:20:27 +0200 Subject: [PATCH] motionpixels/mp_decode_frame_helper: assert that the first pixel doesnt reuse the last. reusing the last would use uninitialized data, this should be impossible currently, but better to check by assert.
