  I try to write a simple transcoding script for VHS backups with ffmpeg. But I fail to handle spaces in filenames.

  I build my ffmpeg command together in the script and echo it and when I copy paste the echoed command it works, but not diretcly from the script.

  Has anayone a idea whats wrong with my script ?

  Script :

  #!/bin/bash
  
  # VHStoMP4Backup Script
  
  
  
  INPUT=$1
  
  OUTPUT="/Volumes/Data/oliver/Video/Encodiert/${2}"
  
  
  
  command="ffmpeg \
  
      -i \"$INPUT\" \
  
      -vcodec copy \
  
      -acodec copy \
  
      \"$OUTPUT\""
  
  
  
  
  
  if [ ! -z "$1" ] && [ ! -z "$2" ] ;
  
  then
  
      echo ${command}$'\n'
  
      ${command}
  
  else
  
      echo "missing parameters"
  
      echo "Usage: script INPUT_FILENAME OUTPUT_FILENAME"
  
  fi
  
  
  
  exit

  Script calling :

  ./VHStoMP4Backup.sh /Volumes/Data/oliver/Video/RAW\ Aufnahmen/Ewelina\ -\ Kasette\ 1.dv ewe.mp4

  Commandline output

  olivers-mac-pro:Desktop oliver$ ./VHStoMP4Backup.sh /Volumes/Data/oliver/Video/RAW\ Aufnahmen/Ewelina\ -\ Kasette\ 1.dv ewe.mp4
  
      ffmpeg -i "/Volumes/Data/oliver/Video/RAW Aufnahmen/Ewelina - Kasette 1.dv" -vcodec copy -acodec copy "/Volumes/Data/oliver/Video/Encodiert/ewe.mp4"

• Raspberry Pi Youtube Stream with ffmpeg : libx264 unknown

  21 juillet 2016, par tm011036

  I want to use my raspberry pi 3 for a youtube stream via an usb camera. Therefore, I compiled and installed the following tools :

  ffmpeg, libx264, libav-tools

  However, when running the following code i always get an error that the libx264 encoder is unknown :

  ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 
  
  -codec:v libx264 -b:v 700k -maxrate 700k -bufsize 700k -an -f 
  
  flv rtmp://a.rtmp.youtube.com/live2/MYYOUTUBECODE

  I installed x264 via clone and make install using this guideline. How can I check if this encoder was installed correctly ? I am already stuck for 2 days on this problem - please help !

  Related hints (e.g. libavcodec-extra codec, type errors) regarding this problem unfortunately also didn’t help further.

  Thank You.
