• high CPU usage with ffmpeg and youtube live stream

  21 mai 2018, par Sergio santa

  I have a problem with high CPU usage using FFmpeg to stream my videos via youtube.
  my main purpose is to stream loop videos as long as possible but after 6 hours the stream stops and the CPU usage was almost 90%.

  the code I’m using

  ffmpeg -re -stream_loop -1 -i video.mp4 -vcodec libx264 -preset veryfast -maxrate 2500k -bufsize 3368k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 198k -ar 44100 -f flv -s 1280x720 -max_muxing_queue_size 400 rtmp://a.rtmp.youtube.com/live2/xxxxxxxxx

  My VPS details :
  1 vCPU, 3 GB memory

• RTSP to RTMP Youtube Live only displays online for few seconds

  2 juin 2016, par Poison

  I’m trying to get the feed from an IP camera to Youtube Live. Simple enough uh.

  The command I’m using is the usual :

  ffmpeg -i rtsp://user:pass@ip:port/videoMain -f flv -r -s -an rtmp://a.rtmp.youtube.com/live2/per-sonal-code

  What happens

  Live Youtube receives the signal and says its healthy, after two or less seconds a red box appears saying they’re not receiving my signal. After that it displays "No signal". Webcam image is never shown.

  What I’ve tried

  Different parameters (-re, -rtsp_transport tcp, -s 640x480, -g 30, -r 30 ..) and different combinations of them, plus different resolutions, different buffer sizes and stream sizes, and different Ingestion settings on Youtube.

  Followed different very basic stuff tutorials.

  I’ve done it with ffmpeg in Windows 7 and Ubuntu 16.04, different networks (home and work), checked for possible port problems,...

  What confuses me

  Using streaming software like XSplit, or Manycam it actually works on the same computers !
  Also using the different command combinations, Youtube always receives the signal and its healthy before changing and displaying "No signal", its not complaining about low bitrate, or wrong format like I’ve seen in the different tutorials.

  I need to create two different streams for two cams, so ideally I’d prefer to use ffmpeg. However if anyone knows a software that can do this, please tell me. I’ve been stuck with this long enough !

  Thanks.

• How to collect specific Youtube channel uploaded videos and use FFMPEG to convert to MP3 [on hold]

  6 novembre 2014, par Daniel Kirkby

  I am currently attempting to create a php script that can crawl a Youtube channel’s uploaded videos and parse them through FFMPEG to a mp3.

  .eg (https://www.youtube.com/user/PandoraMuslc/videos) download each .flv then convert to mp3 using a script that can do the whole channel instead of one at a time as there are a few hundred uploads. while I have found scripts that can make FFMPEG convert to mp3 and scripts to show the uploaded videos in XML I kinda just want to figure out how to get each video automaticly, Maybe a script that can be cron’d ?
