  • FFMPEG Unable to find a suitable output format for 'pipe :' pipe: : Invalid argument

    1er avril 2021, par ashiyaa nunhuck

    I want to stream video from my drone real time to a WEBUI using ffmpeg. But i get the follwong errors.
The code works but i don't think ishould have gotten this error.
Can somebody help with this issue ? This is my drone commands along with the streaming video codes. I have only added the code to get data.
Below is the error :
pipe error

    


    My code is as follows :

  • Dash.js not playing mpd files made with ffmpeg

    31 décembre 2022, par Macster

    I'm using ffmpeg to create chunks and manifest of a webm file which I want to live stream with Dash.js. Unfortunately Dash.js won't play the mpd file, no matter which way I create the chunks and manifest. However, the sample mpd URL from Dash.js is working.

    UPDATE

    &#xA;

    Well, it seems like the problem in general was, that the mpd's wouldn't play from that /dash folder. So i took a look into the code and found a bad routing. Anyways, the mpd would't start with the given command I used, probably becasue it creates a dynamic manifest, like @Markus Schumann says. So I'm going with a new one which seems to be working for now, but not very well.

    I just would like to have this 4 informations :

    1) Duration: 00:51:05.07, start: 0.100667, bitrate: 0 kb/s
    
2)  File '/media/path/video.mkv' already exists. Overwrite ? [y/N] y
    
3)  Output #0, matroska, to '/media/path/video.mkv':
    
4)  frame= 3000 fps=174 q=-1.0 Lsize=   12325kB time=00:02:00.00 bitrate= 841.4kbits/s

    I’ve tried the -v option, but the output is either -v info (this long output), or -v warning, or -v error. There’s not what I would like to have.
    I’ve seen this question but the output is totally clear. Can I put an exception for specially string ?
    Thanks all

    Edit : my line in my script is like that :

    ffmpeg -i "${M3U2}" -vcodec copy -acodec copy "${Directory}/${PROG}_${ID}.mkv"
