• FFMPEG Streaming USB Webcam Video with Music Playlist

  3 février 2020, par 556duckvader

  Hello I am setting up streaming box that will be using a USB webcam as my video source and I am wanting to add in background audio to the live streams. I am wanting to do this by specifying a playlist and have it play through the audio files and then loop back once the playlist is finished. I have the ffmpeg command that allows me to stream the USB webcam and I can get one audio file to play but I can’t get seem to figure out how to get the playlist to work. Any help would be great. Below is what I have that is working.

  ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 -i /home/pi/twitchMusic/ES_Arrows-MarVei.mp3 -c:a copy -c:v libx264 -r 24 -rtbufsize 1500k  -preset ultrafast -crf 23 -force_key_frames 'expr:gte(t,n_forced*2)' -minrate 2200k -maxrate 2200k -pix_fmt yuv420p -b:v 2500k -bufsize 2200k -f flv rtmp://live.twitch.tv/app/TWITCH_KEY

• How to modify music pitch in audio of video file and still sound natural

  9 janvier 2020, par Keith Bennett

  I have some karaoke .mp4 video files (legally obtained) for Thai songs, and want to convert the pitch downward to fit my singing range. I’ve gotten most of the way there thanks to https://superuser.com/questions/292833/how-to-change-audio-frequency/1076762#1076762
  using a command line like this :

  ffmpeg -i in.mp4 -af 'asetrate=35280.0,atempo=1.25' out.mp4

  ...but the instruments and human singing voices don’t sound natural at the modified pitch.

  Is there a better way to change the pitch ? I know some commercial products can do this.

  By the way, I wrote a Ruby script to simplify this ffmpeg call ; it’s at https://gist.github.com/keithrbennett/9ba7043792bfb2fcc92d615076a8413f. It enables you to specify a single factor, and modifies both pitch and tempo accordingly.
