Super resolution video format?

Hello,

I can't find a list of possible video formats for super resolution. I've only seen people use .avi on forums. Would it work with .mp4 as well?

Where can I find documentation for this? (http://docs.opencv.org/modules/superr... doesn't quite cut it).

Thanks in advance for your reply!

Indeed I know this example, but it doesn't provide any clues as to what the inputVideoName is...

Have you solve your problem? It's not really an answer but may be it could help you. After you can change cv::superres::createFrameSource_Camera(0) in createFrameSource_Video(name); where name is pathname to your file. I think that's video format can be any format that opencv (ffmpeg ) can read .

I start working on Superres my program is (very slow) (using samples/gpu/super_resolution.cpp). Becarefull I use twice usb device 0 (my webcam). It works on windows but I'm not sure that's good on all platform.

#include <opencv2/opencv.hpp> 
#include "opencv2/superres.hpp"

using namespace cv;
using namespace std;
using namespace cv::superres;


int main(int argc, char** argv)
{

    Ptr<cv::superres::FrameSource> f;
    f = cv::superres::createFrameSource_Camera(0);
    Ptr<cv::superres::SuperResolution >sr;

    VideoCapture vid;
    vid.open(0);

    sr = cv::superres::createSuperResolution_BTVL1();
    Ptr<DenseOpticalFlowExt> of = cv::superres::createOptFlow_Farneback();

    int scale = 2;
    sr->setOpticalFlow(of);
    sr->setScale(scale);
    sr->setTemporalAreaRadius(2);
    sr->setIterations(2);
    Mat frame;
    char c;
    Mat frameZoom;
    Mat mZoom;
    Mat v;
    f->nextFrame(frame);
    sr->setInput(f);
    do{
        //if (vid.grab())
        {
            sr->nextFrame(frame);
            imshow("Video SuperRes", frame);
            if (vid.grab())
            {
                vid >> v;
                resize(v, mZoom, Size(0, 0), scale, scale);
                imshow("Video Scale", mZoom);

            }
                imshow("Video SuperRes", frame);
            c = waitKey(20);
        }

    } while (c != 27);
    return 0;
}
