• FFmpeg + HTTP Images - How to recover from lost connection ?

  20 juin 2019, par user11588722

  I have a command which works very well, but stops dead if the connection is lost for even a second. The images are remotely hosted. Is there a way to prevent the command from completely stopping ? Maybe make it continue after the connection comes back ?

  ffmpeg -y -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i "Temp/images.txt" -i "Assets/screen.png" -i "Temp/audio.mp3" -filter_complex "[0]scale=3840x2160,zoompan=z='if(lte(zoom,1.0),1.2,max(1.001,zoom-0.0010))':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':fps=15:d=200[p];[p][1]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2, drawtext=fontfile=Assets/Fonts/Heathergreen.otf:text='%%~ni':fontcolor=black:fontsize=32:x=90:y=582[v];[2:a]showwaves=mode=cline:s=110x36:r=15:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[v][w]overlay=77:444,scale=1280:720[outv]" -map "[outv]" -map 2:a -c:v libx264 -c:a aac -preset ultrafast -shortest "Temp/video.mp4"

  I’ve tried looking into FFmpeg documentation and tried timeouts and other options, but either they don’t work or (more likely) I’m doing something wrong.
  Any advice would be appreciated. Thank you.

• Automatically fade audio

  25 mars 2019, par Nadav Tasher

  I have a working script that plays a different audio every 45 minutes.

  The audio files change on a daily basis, so i cant manually fade them in/out in Audacity.

  In the script, i have the following line :

  ffplay -i /home/user/Ringtone1.mp3 -ss 00:00:7 -t 20 -nodisp -autoexit

  But every time, the audio cuts abruptly after 20 seconds, which isn’t very ear-pleasing.

  I want to make the audio fade in from 0 to max in 5 seconds and then fade out from max to 0 in 5 seconds (at the end of the 20 seconds).

  How can i do that ?
