Comment (by gjdfgh):

 {{{
     pDest = avcodec_alloc_frame();
     avpicture_alloc((AVPicture *)(pDest), PIX_FMT_BGRA, 1, 60);
 }}}

 This is as broken as it gets. I think the rule is: never use AVPicture.

 You can allocate a frame with av_frame_get_buffer(). You have to set the
 image parameters separately before calling this function.
