• Fixing a TS file made by the HD Home Run

  2 mars 2015, par clive alton

  I am recording from a cable stream using the hdhomerun command line tool, hdhomerun_config, to a .ts file. The way it works is that you run the command, it produces periods every second or so to let you know that the stream is being successfully recorded. So when I record, it produces only periods, which is desired. And the way to end it is by doing a Ctrl-C. However, whenever I try to convert this to an avi or a mov using FFMpeg, it gives a bunch of errors, some of which being

  [mpeg2video @ 0x7fbb4401a000] Invalid frame dimensions 0x0
  
  [mpegts @ 0x7fbb44819600] PES packet size mismatch
  
  [ac3 @ 0x7fbb44015c00] incomplete frame

  It still creates the file, but it is bad quality and it doesn’t work with OpenCV and other services. Has anyone else encountered this problem ? Does anyone have any knowledge that may help with this situation ? I tried to trim the ts file but most things require conversion before editing. Thank you !

• Assigning variable a home file path returns warning

  28 mai 2015, par Code_Ed_Student

  I am working with ffmpeg and bash. The question that follows is more in relation to bash scripting variable assignment. I compiled ffmpeg from source using the guide. There are two ways to invoke ffmpeg : cd ~/bin && ./ffmpeg -i ~/input.mp4 ~/videos/output.mkv or /home/yourusername/bin/ffmpeg ... . However in my script I am trying to set path to a variable and it returns the error Using a password on the command line interface can be insecure. How can I properly call the program without this warning ?

  #!/bin/bash/
  
  ffprobe_path="/home/yourusername/bin/ffprobe"
  
  
  
  while IFS== read field value; do
  
      details[$field]="$value"
  
  done < <($ffprobe_path -i "$file" -show_format -v quiet | grep '.=.')
  
  
  
  echo "${details[duration]}"

  Result

  Warning: Using a password on the command line interface can be insecure.

• Anomalie #3927 : SVP avec SVP_PREFERER_TELECHARGEMENT_PAR_VCS n’installe pas un plugin du dépôt Ex...

  27 mars 2017

  Et si je lis le .xml, il indique :
  _externals_/github/video_accessible/tags/v0.6.10
  alors que la vraie source de l’external (celle connue de subversion sur ma machine locale) est :
  https://github.com/Cerdic/video_accessible/trunk

  Donc, ça n’est pas directement un problème de SVP, mais du script de génération des depot.xml

  Ne pouvant pas tester, je ne vais pas me risquer à commiter.
  Ceci dit, c’est ici que je serais tenté d’intervenir : https://zone.spip.org/trac/spip-zone/browser/_outils_/smart_paquets/inc_empaqueteur.php#L535
