閱讀姆姆流打開cv

Question

有沒有辦法讀取一個mms流，與開放的CV，直接分析？

我想用C++做一個小項目。並且我不知道如何將mms插入到opencv中。

我想生病需要添加一個庫到視覺工作室。

只有在MMS視頻流即時閱讀：

mms://s3ewm.castup.net/991450009-52.wmv?ct=IL&rg=BZ&aid=145&tkn=201202&ts=0&cu=FC1B06E9-7ABE-4B1C-9B2A-7A5C6019E99F

here有人沒有得到與VLC包彩信。

struct ctx 
{ 
    IplImage* image; 
    HANDLE mutex; 
    uchar* pixels; 
}; 

void *lock(void *data, void**p_pixels) 
{ 
    struct ctx *ctx = (struct ctx*)data; 
    WaitForSingleObject(ctx->mutex, INFINITE); 
    *p_pixels = ctx->pixels; 
    return NULL; 

} 
void display(void *data, void *id){ 
    (void) data; 
    assert(id == NULL); 
} 
void unlock(void *data, void *id, void *const *p_pixels){ 
    struct ctx *ctx = (struct ctx*)data; 
    /* VLC just rendered the video, but we can also render stuff */ 
    uchar *pixels = (uchar*)*p_pixels; 
    cvShowImage("image", ctx->image); 
    ReleaseMutex(ctx->mutex); 
    assert(id == NULL); /* picture identifier, not needed here */ 
} 

int main() 
{ 
    cvNamedWindow("image", CV_WINDOW_AUTOSIZE); 
    libvlc_media_t* media = NULL; 
    libvlc_media_player_t* mediaPlayer = NULL; 
    char const* vlc_argv[] = {"--plugin-path", "C:\\Users\\Oscar\\Documents\\libvlc\\vlc-1.1.4"}; 
    libvlc_instance_t* instance = libvlc_new(2,vlc_argv); 
    mediaPlayer = libvlc_media_player_new(instance); 
    media = libvlc_media_new_path(instance, "mms://81.89.49.210/musicbox"); 

    struct ctx* context = (struct ctx*)malloc(sizeof(*context)); 
    context->mutex = CreateMutex(NULL, FALSE,NULL); 
    context->image = cvCreateImage(cvSize(VIDEO_WIDTH, VIDEO_HEIGHT), IPL_DEPTH_8U, 4); 
     context->pixels = (unsigned char *)context->image->imageData; 

    libvlc_media_player_set_media(mediaPlayer, media); 
    libvlc_video_set_callbacks(mediaPlayer, lock, unlock, display, context); 
     libvlc_video_set_format(mediaPlayer, "RV32", VIDEO_WIDTH, VIDEO_HEIGHT, VIDEO_WIDTH*4); 
    libvlc_media_player_play(mediaPlayer);

    { 
    } 
    return 0;
