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_sdLet’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.

Generate script from Handbrake preset
11 avril 2018, par cclloydIs it possible to generate a script/command to run from a Handbrake preset or from the queue on OS X ?
Like take the queue and generate a command I can run in terminal instead of through the GUI ? (Either with ffmpeg or with HandBrakeCLI)
