• Convert mp4 video to m3u8 format with C# ffmpack

  26 février 2020, par İlyas ARUCA

  I can convert the file with the extension mp4 in my hand from the code line related to PowerShell to m3u8 format.

  ffmpeg -i inputVideo.mp4 -profile:v baseline -level 3.0 -s 960x540 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls outputVideo.m3u8

  But I want to automate this process using C#. I did as written in the document on Microsoft’s site, but I could not add the relevant parameters. Has anyone done anything like this before ? or how can I follow a path.

• How I can load testing my web application if I host it in Azure and Google Cloud

  29 décembre 2018, par Anirudha Gupta

  I am trying to stream the video on Youtube using FFmpeg. Earlier I have a preset which is used to stream at lower resolution.

  Now I want to send the video as it is. I am trying to use this code

  ./ffmpeg -re -i "C:\Users\Anirudha\Desktop\abc.mp4" -codec copy -f flv "rtmp://a.rtmp.youtube.com/live2/mykey1"

  I got this code from here https://www.wowza.com/docs/how-to-configure-security-using-wowza-streaming-engine-manager

  This code is working fine for Wowza but it’s shown running on youtube (in the command line) in Actual it’s not doing anything on the youtube website.

  Is there any way to send the file to youtube the file as it is, What I am looking for is I don’t want to do anything on file. Let the resolution same as it is.

• FFmpeg av_guess_format returns NULL

  12 septembre 2014, par Kage

  I’m following the example code here : http://cekirdek.pardus.org.tr/ ismail/ffmpeg-docs/output-example_8c-source.html

  My code is as follows :

  fmt = av_guess_format(NULL, filename, NULL);
  
  if (!fmt) {
  
          LOGE(1,"Could not deduce output format from file extension: using MPEG.\n");
  
          fmt = av_guess_format("mp4", NULL, NULL);
  
  }
  
      if (!fmt) {
  
          LOGE(1, "Could not find suitable output format\n");
  
          exit(1);
  
  }

  The two times that I call av_guess_format, it is returning NULL both times.
  I am calling both av_register_all() and avcodec_register_all() beforehand.

  Any ideas as to why this is returning NULL ?

  Thanks in advance.
