• Need Help Making c# Discord Music Bot [on hold]

  6 mars 2017, par Greg Varadi

  A few days ago I started making a discord bot. I have included a lot of commands and functions but now I want to make my bot able to play music.
  My bot can join the voice channel and play music from MP3 files (local file or link) with ffmpeg. I’m using this documentation for the ffmpeg. But I want to make the bot play music from Youtube using the Youtube link it receives.. Youtube-dl can solve this problem but I don’t know how to use it. If anyone know how to use it help me.

• Pausing video streaming at EOF with FFMPEG ( Streaming and saving simultaneously)

  6 novembre 2019, par Padfoot

  I am writing a video to a local file using videowriter in OpenCV and at the same time, I am streaming it using ffmpeg+RTSP.
  But my video writing is slower than streaming. So RTSP is reaching the EOF and streaming is stopped.

  Is there any way or option in FFMPEG to pause the stream if it reached EOF and resumes again from the same time point.

  EDIT

  System - Ubuntu 16, 32 GB RAM.

  For video writing (frame by frame) -

       int i = 0;
  
  
  
      VideoWriter video("output.mp4",CV_FOURCC('a','v','c','1'),25, Size(frame_width,frame_height)); 
  
          while(1)
  
          { 
  
              Mat frame; 
  
  
  
              cap >> frame;
  
  
  
              if (frame.empty())
  
              break;
  
  
  
              video.write(frame);
  
  
  
      if (i == 25)
  
      printf("Start streaming");
  
  
  
       i++;
  
  
  
  
  
          }

  After writing 25 frames, I am streaming through -

  ffmpeg -re -i output.mp4 -codec copy -f flv rtmp://192.168.0.1:1935/live

• How to generate light weight videos with ffmpeg for Power Point in OS X ?

  25 septembre 2014, par Pablo

  I want to make some movies with ffmpeg to use them on a Powerpoint in Mac OS X. I am using this command, which works well but generates large movies (about 100 MB) without losing too much quality.

  ffmpeg -f image2 -r 100 -pattern_type glob -i 'img*.png' -c:v mjpeg -qscale:v 20 test.avi

  I have also tried using other codecs like mpeg4 and libx264 to generate lighter movies (about 10 MB) but they don’t work correctly in the Powerpoint presentation.

  Does anyone know how to use them correctly or how to create a light weight movie with ffmpeg that works well on Powerpoint for OS X ?
