• Ffmpeg hls segment stop segmenting after 5300 segments

  9 avril 2019, par Hug Duino

  I’m trying to make a http video streaming using hls, ffmpeg and raspivid and I need a replay time of 1 day but after 5300 segments ffmpeg stop segmenting and continue writing the video to the 5301 segment for the end of the day (5300/5301 is an average number, +- 50 segments)
  I have plenty of storage space, my camera can record all the day. The only problem is ffmpeg who decide to stop segmenting after 5300 segments

  Thank you and sorry for my poor english ^^

  Here is my streaming script :

  base="/var/www/html/"
  
  
  
  set -x
  
  
  
  rm -rf /var/www/html/ppc/saves/live live.h264
  
  mkdir -p /var/www/html/ppc/saves/live
  
  
  
  # fifos seem to work more reliably than pipes - and the fact that the
  
  # fifo can be named helps ffmpeg guess the format correctly.
  
  mkfifo live.h264
  
  raspivid -a 1036 -w 1640 -h 1232 -fps 15 -t 37200000 -b 1500000 -o - | psips > live.h264 &
  
  
  
  # Letting the buffer fill a little seems to help ffmpeg to id the stream
  
  sleep 2
  
  
  
  # Need ffmpeg around 1.0.5 or later. The stock Debian ffmpeg won't work.
  
  # I'm not aware of options apart from building it from source. I have
  
  # Raspbian packags built from Debian Multimedia sources. Available on
  
  # request but I don't want to post them publicly because I haven't cross
  
  # compiled all of Debian Multimedia and conflicts can occur.
  
  ffmpeg -y -r 15 -i live.h264 -f alsa  -i default:CARD=C525 -r:a 48000 -ac 1 -af adelay=32s -c:v copy -c:a aac -b:a 128k -map 0:0 -map 1:0 -r 30 \

• Why does ffmpeg.exe started from Windows batch file close immediately without waiting for user input ?

  12 juin 2017, par user2566350

  I searched google for an hour but I could not find anything to fix my issue. I found only "similar" fixes for problems I’m not having.

  I am opening ffmpeg.exe from a batch file that only has ffmpeg.exe with no arguments in it and it doesn’t work even though it did few hours ago.

  If I open command line from the folder and enter ffmpeg.exe it works because it’s not closing ffmpeg but waits for my input which is exactly how the batch file worked before.

  What could be the issue ?

  I have not changed the batch file or ffmpeg one or their locations.

  Running on Windows 7 x64 if that matters.

  Edit : File name is start ffmpeg.bat. It’s content is only ffmpeg.exe which used to work. I also tried start ffmpeg.exe and ffmpeg and changed the filename to 1.bat and 1.cmd but neither worked.

  Edit2 : Sorry i can’t explain myself better my english isn’t very good, however I will try to explain using these images :

  
  This is what i get if i run CMD from the desktop and enter ffmpeg.exe

  
  This is what I get when i run the batch file (after i added pause)
  Batch contents : 1st line=ffmpeg.exe, 2nd line=pause.

  As you can see without the pause ffmpeg will terminate and not remain on the screen like the in first image.

  I tried renaming the file and I tried to run it as admin but neither worked, Any suggestion why is it suddenly not running as it did yesterday ?
