+++ This bug was initially created as a clone of Bug #680796 +++

AVPacket memory needs to be 32-byte aligned at least and needs to have
FF_INPUT_BUFFER_PADDING_SIZE zero-padding at the end. AVFrame needs to have
32-byte aligned memory addresses in every AVFrame.data[] element, and also
needs to use avcodec_align_dimensions2() to get the allocated
width/height/linesize/etc

The video decoder does all that.
