[adland]

this patch fixes the segfault and some video output is displayed

However I also noticed an error output message
DR1 failure is displayed
from code in file libmpcodecs/vd_ffmpeg.c
it needs something fixed in this case
 (the ip_count is 3)

if(ctx->b_count>1 || ctx->ip_count>2){
        printf("DR1 failure\n");

        ctx->do_dr1=0; //FIXME
        avctx->get_buffer= avcodec_default_get_buffer;
        return avctx->get_buffer(avctx, pic);
    }

not sure how this code works and did not change anything here.
good luck
