  • Creating farms of unique websites

    13 avril 2011, par

  • Dynamic Location Offsetting while Desktop Video Capture in FFMPEG [closed]

    18 février 2024, par Zen Of Kursat

    Is there a way to dynamically change offsets during screen capture ?

    


    But these offset values are static (eg. 66 and 77) and we cannot change these values during video recording. Simply, I am trying to record screen with according to mouse coordinates which are of sure changing while video recording starts.

    


    For example :

    


    ffmpeg -f gdigrab -framerate 30 -offset_x 77 -offset_y 66 
       -video_size 1920x1080 -i desktop output.mp4


    


  • Parse dynamic mpd file with Media Source Extensions

    17 février 2023, par FrankC

    I just started learning about adaptive streaming, and currently I'm working on a project that needs showing a live video. In order to control some of the elements in mpd file, I determined to use MSE instead of dash.js. I refer to the code at the following URL :https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/samples/dn551368(v=vs.85)
But I found out that there is no "Initialization" tag or "range" attribute in my mpd file. I don't find any relative attribute as well. By the way I'm use nginx-rtmp + ffmpeg to generate dash file.
So here is my dash file looks like

    


    &lt;?xml version="1.0"?>&#xA; &#xA;  <period start="PT0S">&#xA;    &#xA;      &#xA;        &#xA;          <segmenttimeline>&#xA;             <s t="0" d="10000"></s>&#xA;             <s t="10000" d="10000"></s>&#xA;             <s t="20000" d="5000"></s>&#xA;             <s t="25000" d="10000"></s>&#xA;          </segmenttimeline>&#xA;        &#xA;      &#xA;    &#xA;  </period>&#xA;&#xA;

    &#xA;

    My question is :&#xA;1.Did I have any missing parameters in using ffmpeg or nginx-rtmp resulting in losting tag in mpd file ?&#xA;2.Or there is other way to setup "Initialization"/"range" attribute and let my program work ?&#xA;3.I also curious about why my mpd file doesn't have a baseURL element ?

    &#xA;

    ※My mpd file works fine with dash.js, I can see the video properly

    &#xA;

    THANKS A LOT
