• nginx ffmpeg hls streaming filling up my hard drive

  19 avril 2020, par stefki

  I am using nginx and ffmpeg on my windows 10 machine. Everything works ok, but my hard drive keep filling up .
These are my command lines

  



  ffmpeg -i "http://192.168.1.2:9566/history/" -copytb 1 -filter_complex "[0:v][0:s:1]overlay[v];[v]pp=fd,scale=720:-1[y]" -map [y] -map 0:1 -s 720x576 -pix_fmt yuv420p -b:v 1800k -maxrate 2000k -bufsize 3000k -c:v libx264 -strict 2 -profile:v "main" -preset superfast  -acodec aac -ac 2 -ar 44100 -ab 128k -vsync 1 -async 1 -f hls -hls_time 5 -hls_list_size 6 -segment_wrap 10 -hls_flags delete_segments "D:\media\hls\history.m3u"


  



  The HLS segments goes to D :\media\hls
This drive D : is ok, it's not filling up.

  



  But the C :\ partition is filling up all the time.

  



  the ffmpeg.exe is executed from Folder :
C :\Users\Stefki\Desktop\ffmpeg-latest-win64-static (1)\ffmpeg-latest-win64-static\bin

  



  VLC play link http://192.168.2.254/hls/history.m3u OK

  



  Thank you to all, I hope any experienced dev can help me :)

  



  This is my nginx config file
