youtube to iPod and how to check video files

Last modified on July 24, 2026 • 1 min read • 170 words I was trying to extract the audio file from some youtube  videos in order to play it back from my iPod shuffle. I tried various methods (including the otherwise quite versatile VLC Player  , but finally settled on the following two step procedure:1. Download the flash video (file ending .flv) file to your local disk. You can use any method to accomplish this task, but as usual Firefox  has the perfect plug-in for this task: Download helper  .2. Extract and convert the audio file with ffmpeg  using the following command: ffmpeg -i video-infile.flv audio-outfile.mp3 It is also possible to convert the flv file into a mpeg file. You need to do this e.g. if you want to import the video into iTunes  . For some strange reason Quicktime  can play Flash Videos, but iTunes doesn’t allow their playback. The command is almost the same: ffmpeg -i video-infile.flv audio-outfile.mpegAnother nifty usage of ffmpeg is to check video files for corruption and other problems:ffmpeg -v 5 -i file.avi -f null - 2>error.log
