• How to extract single image (with different name each time) from multiple videos in the one folder using ffmpeg bash script

  15 juillet 2014, par morriscotty_sd

  Let’s start with this... I’m fairly new to Linux.

  I have been looking into ffmpeg to extract an image from a video using the terminal. I’ve accomplished this using this piece of code :

     ffmpeg  -itsoffset -4  -i oggvideo.ogg -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 oggThumb.jpg

  I run this when I’m in the directory which holds the videos in my project. But what I want is to extract an image from all videos in that folder at the same time, naming the image corresponding with the video name it’s extracted from. My end goal is to have a folder which will hold videos that a user uploads, and at a certain time the script will run and extract images from the uploaded videos, saving the image path to a database.

  I found this line of code :

  for %%i in (*.mp4) do ffmpeg -ss 20 -i %%i -t 1 -s 590x340 -f image2 %%i.jpg

  from this site : Trying-to-extract-1-image-from-multiple-videos-with-FFMPEG

  I run that in the terminal and it gives me the error : ’bash : syntax error near unexpected token `(’’
  I tried removing the ’( )’ but then it just takes me onto a new line. This is where I’m having the most problems due to being relatively new to linux commands.

  Any suggestions or advice would be very helpful.

• Annual Release of External-Videos plugin – we’ve hit v1.0

  13 janvier 2017, par silvia

  This is the annual release of my external-videos wordpress plugin and with the help of Andrew Nimmolo I’m proud to annouce we’ve reached version 1.0 !

  So yes, my external-videos wordpress plugin is now roughly 7 years old, who would have thought ! During the year, I don’t get the luxury of spending time on maintaining this open source love child of mine, but at Christmas, my bad conscience catches up with me – every year ! I then spend some time going through bug reports, upgrading the plugin to the latest wordpress version, upgrading to the latest video site APIs, testing functionality and of course making a new release.

  This year has been quite special. The power of open source has kicked in and a new developer took an interest in external-videos. Andrew Nimmolo submitted patches over all of 2016. He decided to bring the external-videos plugin into the new decade with a huge update to the layout of the settings pages, general improvements, and an all-round update of all the video site APIs which included removing their overly complex SDKs and going straight for the REST APIs.

  Therefore, I’m very proud to be able to release version 1.0 today. Thanks, Andrew !

  Enjoy – and I look forward to many more contributions – have a Happy 2017 !

  NOTE : If you’re upgrading from an older version, you might need to remove and re-add your social video sites because the API details have changed a bit. Also, we noticed that there were layout issues on WordPress 4.3.7, so try and make sure your WordPress version is up to date.
