• ffmpeg : getting video from http page streamed to youtube

  28 novembre 2014, par M-T-A

  I’m trying to configure ffmpeg to stream to youtube from ubuntu machine.

  I have my wifi camera streaming with format ’video/x-ms-asf’ on local http page.

  Then I use these commands in attempt to stream to youtube

  VBR="2500k" # Bitrate 
  
  FPS="20" # FPS 
  
  QUAL="medium" #ffmpeg quality
  
  YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2" # URL base
  
  
  
  SOURCE="http://192.168.9.XX/videostream.asf?user=admin&pwd=***" # Source of video
  
  KEY="KEY HERE" # youtube event key
  
  
  
  ffmpeg \
  
  -i "$SOURCE"  \
  
  -vcodec copy -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
  
   -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \
  
  -f flv "$YOUTUBE_URL/$KEY" 

  I get this output

  Suddenly the streaming stops and the terminal hangs. I’m not sure why. Is it because the video has no audio in streaming ?

• Continuous YouTube live stream via ffmpeg keeps failing after a while [closed]

  23 octobre 2024, par dooleyo

  I am trying to stream a simple MP4 file as a 24/7 YouTube radio station on repeat from a virtual machine using ffmpeg. It's only a 23 minute ( 1GB) file, and runs fine for hours or even days, then hangs up. I've tried on a small Digital Ocean droplet and detaching the ssh session with screen. I am using -c copy so I don't need to process or re-encode anything (even on the smallest droplet, the memory/cpu utilization is negligible, so I know that's not the issue). I have even tried some of ffmpeg's auto-restart options to no avail. Here is the command I'm currently running :

  


  ffmpeg -stream_loop -1 -re -i file.mp4 -c copy -drop_pkts_on_overflow 1 -attempt_recovery 1 -recover_any_error 1 -recovery_wait_time 1 -f flv "rtmp://x.rtmp.youtube.com/live2/{STREAM_KEY}"

  


  This works perfectly, for a time, then hangs up with :

  


  aost#0:1/copy @ 0x623b201c5fc0] Error submitting a packet to the muxer: Broken pipe

size= 9897524kB time=03:24:40.66 bitrate=6602.3kbits/s speed=   1x


  


  There are not many articles I've found covering the broken pipe issue, but those that do seem to involve either A) streams that won't start, or B) streams where the broken pipe occurs the first time the input tries to loop (neither of which are my problem, since it streams and loops fine for quite a while).

  


  Thanks in advance !

  


• Converting a large number of MP3 files to videos for YouTube, each using same the JPEG image

  25 juin 2020, par David

  I am looking for a way to convert large number of MP3 files to videos, each using the same image. Efficient processing time is important.

  


  I tried the following :

  


  ffmpeg -i image.jpg -i audio.mp3 -vcodec libx264 video.mp4


  


  VLC media player played the resulting video file with the correct sound, but a blank screen.

  


  Microsoft Media Player played the sound and showed the intended image. I uploaded the video to YouTube and received the message :

  


  


  "The video has failed to process. Please make sure you are uploading a supported file type."

  


  


  How can I make this work ?
