• ffmpeg livestream alway stop after 160hours streamming

  2 avril 2018, par JerryJumper88

  I use ffmpeg with this code to run stream youtube 24/7 from Windows VPS. But stream alway stop after 160-167 hours and I don’t know why.

     dir/b/s "C:\Users\NASA\Desktop\ffmpeg\bin\1\*.mp4" > list.txt
  
  :encode video
  
  :loop
  
  for /F "delims=;" %%F in (list.txt)  DO ffmpeg -re -i "%%F" -vcodec libx264 -preset veryfast -maxrate 2500k -bufsize 3368k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 198k -ar 44100 -metadata title="" -metadata artist="" -metadata album_artist="" -metadata album="" -metadata date="" -metadata track="" -metadata genre="" -metadata publisher="" -metadata encoded_by="" -metadata copyright="" -metadata composer="" -metadata performer="" -metadata TIT1="" -metadata TIT3="" -metadata disc="" -metadata TKEY="" -metadata TBPM="" -metadata language="eng" -metadata encoder="" -f flv -s 1280x720 rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx
  
  goto loop

  And this is stream log. I google " Larger timestamp than 24-bit : 0xffffff9f" but nothing about this error. I contacted to admin server system, he comfirmed that has no issue connection. Then I tried again in Windows 7 and Windows server 2012, same result, still drop after 160h on youtube.

      Larger timestamp than 24-bit: 0xffffff9f

• ffmpeg on ubuntu - how to stop recording the video ?

  27 mai 2018, par Dcbnvn

  I use program ffmpeg to record video from screen :

  ffmpeg -f x11grab -r 15 -s 1280x1024 -i :1 -vcodec h264 -crf 30 -fs 600000 -y myvideo.mp4 -nostdin -nostats < /dev/null > /dev/null 2>&1 &

  I set option -fs (from help : -fs limit_size set the limit file size in bytes)

  The recording is executing in background

  My question is - Is there any command in ffmpeg, that allows to stop recording ? I call ffmpeg from bash script and after that I invoke other script, so I need to stop recording exactly after second script executed.
