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.
