• Upload part of a video files to server

  10 septembre 2014, par Peter Lur

  I want to make a webpage where you can upload a video to the server (let say using a File Input HTML TAG). I would like to know if it’s possible in ANY languages to upload only small parts of the video files without uploading the whole file first and then splitting the file.

  Let me give you an example of what I am trying to achieve. I am trying to create a service where one upload a long & big video file and I give them 10 samples segment of the video file as a result.

  Let say I have a 1 hours long & /1 Gig size video (avi) file.

  I would like to get a sample of 10 segments of 1 minutes spread across the entire file uploaded to the server.

  I know that I could upload the whole file and then split it but uploading a 1G file would be way long for the user.

  I want to know if upfront there is a way to choose what part of the file need to be uploaded so I could upload only specific segments and then re-construct the files to make them readable.

  I know this is more of a subjective question and it may not be well fitted for Stack Overflow but I really need to figure out how to do that.

• ffmpeg youtube livestream not working

  21 avril 2017, par Select

  Today i tried using ffmpeg on my debian 8.3 server to livestream 24/7 hours. However it doesnt work.

  #! /bin/bash
  
  
  
  INRES="1280x1024" # input resolution (The resolution of the program you want to stream!)
  
  OUTRES="1024x790" # Output resolution (The resolution you want your stream to be at)
  
  FPS="60" # target FPS
  
  QUAL="ultrafast" 
  
  # one of the many FFMPEG presets that can be used 
  
  # If you have low bandwidth, put the qual preset on 'ultrafast' (upload bandwidth)
  
  # If you have medium bandwitch put it on normal to medium or fast
  
  STREAM_KEY="hidden" # this is your streamkey
  
  
  
  
  
  
  
  
  
  ffmpeg -f "file.avi" -s "$INRES" -r "$FPS" -i :0.0 \
  
  -f alsa -ac 2 -i pulse -vcodec libx264 -s "$OUTRES" \
  
  -acodec libmp3lame -ab 128k -ar 44100 -threads 0 \
  
  -f flv "rtmp://a.rtmp.youtube.com/live2" 

  it gives me the output

  Unknown input format : ’file.avi’
