  • 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

    THANKS A LOT

  • Resizing 360 stereoscopic video with FFMPEG

    13 mars 2018, par Miriam Tschanen

    I’m trying to prepare a 360 stereoscopic video from our VR app for streaming. We’d like to offer the video in different resolutions to accomodate varying internet speeds. The original file is 3840x2160 and 463MB large.

    I tried using the naive FFMPEG command :
    ffmpeg -i video_3840.mp4 -vf scale=2560:1440 video_2560.mp4

    However, this seems to remove the stereoscopic / 360 properties of the video, at any rate the Windows video player no longer lets me pan around the view and the file size is down to 74MB, which seems a bit extreme.

    Does anyone know which other flags I should set ? Note that I have absolutely no clue about filming or video formats, so I don’t even know what the original file is encoded as. Ideally I’d like to copy over as many settings as possible. The only thing I want to change is the resolution.

    Any help would be greatly appreciated.

  • how to change the fps of video during playback of video without restarting video

    8 juin 2018, par Mahek Delawala

    I want to change the fps of video at run time (during the playback of video) without restarting or pausing using ffmpeg. I searched about it in the internet but I am not able to get the command which can change the fps directly without restarting the video but i found ffmpeg command which can create a new file with modified fps as shown below.
    ffmpeg -y -r 20 -i input_file -r 45 output_file
    Is it possible to change fps of video during run time using ffmpeg command ? If yes please provide me the command if not how can i change using c code. Please help me in this issue as early as possible.
    Thank you.
