Results are same as before.
FFdshow uses its own ffmpeg and ffmpeg-mt
after viewing the svn content 
<http://ffdshow-tryout.svn.sourceforge.net/viewvc/ffdshow-tryout/trunk/src/ffmpeg-mt/libavcodec/>.
There's no libavcodec/w32thread.c in ffdshow
source.
Looking at this file in ffmpeg-mt.git:master, show
no support for thread_type FF_THREAD_FRAME.

int avcodec_thread_init(AVCodecContext *s, int thread_count){
    int i;
    ThreadContext *c;
    uint32_t threadid;

    if(!(s->thread_type & FF_THREAD_SLICE)){
        av_log(s, AV_LOG_WARNING, "The requested thread algorithm is not 
supported with this thread library.\n");
        return 0;
    }

    s->thread_count= thread_count;
    s->active_thread_type= FF_THREAD_SLICE;
