What is the easiest way to run a FFMpeg screen recording command with a custom keyboard shortcut? Adding my raw ffmpeg command to a Custom Shortcut in the Keyboard settings doesn't do the trick.



Here's the command I'm using: 



ffmpeg -f x11grab -s 1366x768 -i :0.0 -r 25 -vcodec libx264 `date +%Y-%m-%d_%H-%M-%S`_BTEVCpcampFormBook.mkv


The command works fine in terminal. It runs until you terminate it and outputs the file as expected, and running it as a keystroke doesn't appear to do anything, at least visibly. Also, running



gnome-terminal -e "ffmpeg -f x11grab -s 1366x768 -i :0.0 -r 25 -vcodec libx264 `date +%Y-%m-%d_%H-%M-%S`_BTEVCpcampFormBook.mkv"


does open up a terminal window and run a function for a split second, but then the window closes again immediately. Adding "; bash" to the end of the string doesn't keep the window open. Managed to get a screenshot of the terminal window right before it closes, it seems to be terminating mid-execution of the function without displaying any errors. Here that is:

I'm running Ubuntu 16.04.3 LTS.

  • Don't know anything about the shortcut component of the question, but ffmpeg -f x11grab -s 1366x768 -i :0.0 -r 25 should be ffmpeg -f x11grab -video_size 1366x768 -framerate 25 -i :0.0. More info: x11grab docs.

Found a solution. Running the command with "-x sh -c" as opposed to "-e" executes the function without exiting the window. Syntax borrowed from this superuser discussion.



The full function:



gnome-terminal -x sh -c 'ffmpeg -f x11grab -s 1366x768 -i :0.0 -r 25 -vcodec libx264 `date +%Y-%m-%d_%H-%M-%S`_BTEVCpcampFormBook.mkv; exec bash'

    As I mentioned in the comment your -r is incorrect. By coincidence it won't make a difference as is since 25 is the default for x11grab, but if you change it to any other value it will have to perform a frame rate conversion from 25 to your -r value. To prevent that remove -r and replace it with -framerate, and move it so it is an input option (before the -i).

How to enroll fingerprints to Ubuntu 17.10 with VFS491

Image
Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
