  • WebM live streaming via DASH

    4 juin 2018, par ewack

    I am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :

    Could not write header for output file #0 (incorrect codec parameters ?): Operation not permittedStream mapping: Stream #0:0 -> #0:0 (copy)

    Here’s all of my code :

    var express = require('express');
    
spawn = require('child_process').spawn;
    

    
var app = express();
    

    
app.use(express.static(__dirname + '/public'));
    

    
app.listen(8080);
    
console.log("Running on Port 8080");

    Why is ffmpeg creating an empty .mpd file ?

  • Correct recording time of the first frame of a video

    27 juillet 2017, par Vítor Cézar

    How do I get the correct time of the first frame recorded on a video ? I executed the command

    ffprobe -v error -show_streams [file_path]

    and got these values of timecode and creation time for the first stream :

    TAG:creation_time=2017-07-26T16:48:10.000000Z
    
TAG:language=eng
    
TAG:handler_name=   GoPro AVC
    
TAG:encoder=GoPro AVC encoder
    
TAG:timecode=17:21:54:28

    The problem is that the video started being recorded on 16:48:11:504 and neither timecode nor creation time shows this value. If possible I need the precision on milliseconds.
