  • Load first generated dynamic control then load next

    13 juillet 2015, par prasanas
            private void AddControls(int ControlNumber) {
    
        HtmlGenericControl divContent = new HtmlGenericControl("div");
    
        divContent.ID = "Panel";
    
        divContent.Attributes.Add("class", "div");
    
        UpdatePanel1.ContentTemplateContainer.Controls.Add(divContent);
    
        System.Threading.Thread.Sleep(1000);
    
        }

    Why i am adding system.thread because instead of wait command we are using ffmpeg convertor to generate thumnails of video’s it takes around 2 seconds for each video file.

    Consider there are 5 video files. The div takes 10 seconds to load. The whole page gets stucked and after loading all 5 videos we can see it.

    Is there a way like updatepanel or some other to load each file and load next.

        TextBox txtValue = new TextBox();
    
        txtValue.ID = "txtValue" + ControlNumber;
    
        PlaceholderControls.Controls.Add(txtValue);
    

    
        //add button
    
        Button btnAddNext = new Button();
    
        btnAddNext.Text = "Add Control " + ControlNumber;
    
        btnAddNext.ID = "btnAddNext" + ControlNumber;
    
        int NextControl = ControlNumber + 1;
    
        btnAddNext.CommandArgument = NextControl.ToString();
    

    
        btnAddNext.Command += new CommandEventHandler(btnAddNext_Command);
    
        PlaceholderControls.Controls.Add(btnAddNext);
    

    
        //add a line break
    
        PlaceholderControls.Controls.Add(new LiteralControl("<br />"));
    
        System.Threading.Thread.Sleep(1000);
    
        return btnAddNext.UniqueID;
    
        }
    
</string></string></string>

    For above code is sample it loads after 5 seconds loading all 5 elements. I want to load like 1sec- 1 element then 2Seconds load 2nd like this..at 5th second load 5 element.

  • xuggler failed to write header to container

    13 juillet 2015, par user3601262

    I am trying to download video from RTSP stream to a file on my computer using the Xuggler 5.4 library.

    String outputFilename = "D:\\downloadedrtsp.avi";
    
String inputSource = "rtsp://[ip-address]:[port]/user=[username]&amp;[password]=password&amp;channel=1&amp;stream=1.sdp";
    

    
    try {
    
        IContainer container = IContainer.make();
    
        IMetaData im = IMetaData.make();
    
        im.setValue("max_delay", (1000000l) + "");
    
        int retval = im.setValue("rtsp_transport", "tcp");
    

    
        container.open(inputSource, IContainer.Type.READ, null, false, true, im, null);
    
        IMediaReader mediaReader = ToolFactory.makeReader(container);
    

    
        IMediaWriter mediaWriter = ToolFactory.makeWriter(outputFilename, mediaReader);
    

    
        mediaReader.addListener(mediaWriter);
    

    
        IError error;
    
        while ((error = mediaReader.readPacket()) == null) {
    
            logger.info("reading packet");
    
        }
    
    } catch (Exception e) {

  • ffmpeg compilation failed with cuda, libnpp not found

    28 avril 2019, par Q_SJ

    image : docker tensorflow/tensorflow:1.10.0-devel-gpu-py3
    os : ubuntu 16.04
    cuda : 9.0.176

    ffmpeg pulled from github and nv-codec-headers downloaded from videolan, both the latest version

    step 1 : cd /nv-codec-headers and make && make install

    step 2 : cd /ffmpeg (the ffmpeg source) , ./configure —extra-cflags=-I/usr/local/include —extra-ldconfig=-L/usr/local/lib —enable-gpl —enable-lbopus —enable-librtmp —enable-libx264 —enable-nonfree —enable-libnpp —enable-cuvid —enable-nvenc —enable-cuda

    output : ERROR : libnpp not found

    I also tried compiling ffmpeg with cuda 10, but it seemed the same problem. but if I deleted "—enable-libnpp" then ./configure works.

    the config.log has many errors :
