avcodec/vp3: Add missing check for av_malloc
Since the av_malloc() may fail and return NULL pointer, it is needed that the 's->edge_emu_buffer' should be checked whether the new allocation is success. Fixes: d14723861b ("VP3: fix decoding of videos with stride > 2048") Reviewed-by: Peter Ross <pross@xvid.org> Signed-off-by: Jiasheng Jiang <jiasheng@iscas.ac.cn> (cherry picked from commit 656cb0450aeb73b25d7d26980af342b37ac4c568) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
