[libav-devel] [PATCH 04/15] mpegvideo: align width to 32 for scratch buffer sizes

2012-12-12 Thread Janne Grunau
cmdutis.c's alloc_buffer() uses aligned to 32 width plus 2 edges of 32 pixels as linesize. emu_edge_buffer has to work with the same stride. This makes only a difference for 8 bit per pixel bit depths since we always allocate for 16 bit per pixel. Fixes fuzzed sample nasa-8s2.ts_s244342. ---
