• Download brightcove video

  17 mai 2015, par desert877

  So I have sucessfully downloaded flash videos on in the past but for some reason I am having issues with a local news report. The video I am trying to download is :

  http://www.kens5.com/story/news/2015/04/07/one-dead-after-shooting-at-north-side-auto-body-shop/25444855/

  When I check network sources I get the following output :

  http://kens-vh.akamaihd.net/z/video/25446645/25446645_,350,640,1000,2000,.mp4.csmil/3_5e4ebc852f616aa3_Seg1-Frag7?videoId=4159855028001&lineUpId=&pubId=3616287834001&playerId=3626703558001&affiliateId=&als=16.11,30,12.83,3,2176,13298,30,0,0,114,f,7.9,101.94,f,s,SCJIPJRDQHXW,3.4.0,114&hdcore=3.4.0

  I downloaded a tool recommend to me call ffmpeg and ran a command from a forum that said "Invalid data found when processing input". Unable to figure out issue there.

  Does any one know any scripts/code/tools/methods whatever that I can use to download this video ?

  Any help would be great.

• Unable to find suitable output format for 'libmp3lame' and 'flv'

  24 février 2017, par user2108727

  Currently I am trying to setup a livestream using ffmpeg in Kubuntu. I got really far, but unfortunately I cannot figure out one bit that mentions output format errors. Here’s the code I am using for my .sh file :

  #! /bin/bash
  
  
  
  # streaming on Ubuntu via ffmpeg.
  
  # see http://ubuntuguide.org/wiki/Screencasts for full documentation
  
  
  
  # input resolution, currently fullscreen.
  
  # you can set it manually in the format "WIDTHxHEIGHT" instead.
  
  INRES="1920x1200"
  
  
  
  # output resolution.
  
  # keep the aspect ratio the same or your stream will not fill the display.
  
  OUTRES="1280x720"
  
  
  
  # input audio. You can use "/dev/dsp" for your primary audio input.
  
  #INAUD="pulse"
  
  
  
  # target fps
  
  FPS="30"
  
  
  
  # video preset quality level.
  
  # more FFMPEG presets avaiable in /usr/share/ffmpeg
  
  QUAL="ultrafast"
  
  
  
  # stream key. You can set this manually, or reference it from a hidden file     
  
  like what is done here.
  
  STREAM_KEY=$(cat ~/.twitch_key)
  
  
  
  # stream url. Note the formats for twitch.tv and justin.tv
  
  # twitch:"rtmp://live.twitch.tv/app/$STREAM_KEY"
  
  # justin:"rtmp://live.justin.tv/app/$STREAM_KEY"
  
  STREAM_URL="rtmp://live-cdg.twitch.tv/app/$STREAM_KEY"
  
  
  
  ffmpeg \
  
  -f alsa -ac 2 -i "$INAUD" \
  
  -f x11grab -s "$INRES" -r "$FPS" -i :50.0 \
  
  -vcodec libx264 -s "$OUTRES" -preset "$QUAL" -crf 22\
  
  -acodec libmp3lame -threads 6 -q:a 0 -b:a 160k \
  
  -f flv -ar 44100 "$STREAM_URL"

  Now the issue is that whenever I run the .sh file, I get an error at the end saying

  Unable to find a suitable output format for 'libmp3lame'
  
  libmp3lame: Invalid argument

  So I decided to troubleshoot by removing the audio line at the bottom and it just turned into

  Unable to find a suitable output format for 'flv'
  
  flv: Invalid argument

  Something tells me this is because the stream key is not defined properly, but I have no idea whatsoever how to fix this.

  So does anyone have an idea ?
  Thanks in advance !
