• Streaming to YouTube from DJI-SDK

  6 avril 2017, par d0n13

  I’m trying to figure out how to take the camera frames in the DJI-SDK and push them to some form of encode so that I can create a live stream for YouTube.

  Has anybody got this working ? I understand most people use FFmpeg for streaming but my understanding is basic enough on how that project works.

  I’d love if somebody could share some resources on how we could go about getting this to work. I’ve seen the question on the web but I’ve found nothing that comes close to getting a solution for this.

  I need it for a project and there is a commercial solution available but it’s expensive and I can’t afford it and I’d be happy enough to code this if I can understand how to go about it and maybe get some help.

  I’d be happy enough to make an open source version of this is anyone can help.

  Thanks guys, hope we can make this...

• ffmpeg/ffprobe input as buffer stream, get an error always

  13 décembre 2023, par hhk

  


  Code to reproduce

  


  I attached the test.gif file on https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/assets/122068264/e1f3aa31-5386-4dab-a409-9a224e0610fe

  


  
const ffprobeInstaller = require('@ffprobe-installer/ffprobe');
const ffmpeg = require('fluent-ffmpeg');
const { Readable } = require('stream');
const fs = require('fs');


(async () => {

    const buffer = fs.readFileSync('test.gif');
    let readableStream = new Readable();
    readableStream._read = () => { };
    readableStream.push(buffer);
    readableStream.push(null);

    // console.log(ffprobe.path, ffprobe.version);
    ffmpeg.setFfprobePath(ffprobeInstaller.path);
    let metadata = await get_video_meta_data(readableStream);

    async function get_video_meta_data(stream) {
        return new Promise((resolve, reject) => {
            new ffmpeg()
                .input(stream)
                .ffprobe((err, data) => {
                    // console.log(err);
                });
            resolve();
        });
    }
})();





  


  (note : if the problem only happens with some inputs, include a link to such an input file)

  


  Expected results

  


  data should include duration but empty.

  


  Observed results

  


  data is empty and err happens.
Here is error data :

  


  
  libavutil      58.  1.100 / 58.  1.100
  libavcodec     60.  2.100 / 60.  2.100
  libavformat    60.  2.100 / 60.  2.100
  libavdevice    60.  0.100 / 60.  0.100
  libavfilter     9.  1.100 /  9.  1.100
  libswscale      7.  0.100 /  7.  0.100
  libswresample   4.  9.100 /  4.  9.100
  libpostproc    57.  0.100 / 57.  0.100
pipe:0: Input/output error


  


  I only need the metadta for the input gif file. specifically, duration field.
