Custom action to convert webm to mp4

This is the command to convert a .webm to a mp4.

ffmpeg -i 2018-07-28-222352.webm -qscale 0 sample.mp4

This is the thunar custom action I came up with, but it is not working.

ffmpeg -i %f.webm -qscale 0 %f.mp4

Can someone please help me?

Thanks.

Re: Custom action to convert webm to mp4

Are you using that line in the action? You may want to create a script and call it with the action.

Re: Custom action to convert webm to mp4

ffmpeg -i %f.webm -qscale 0 %f.mp4

%f is the full path and filename - meaning you don't add the extension. So:

ffmpeg -i %f -qscale 0 %f.mp4

Re: Custom action to convert webm to mp4

I have some of those Custom Actions, but I prefer to see the output in a terminal, so the commands are of the type:

xfce4-terminal -x ffmpeg -i %f [options] %f.ext

Thanks.

It worked and produced this.

test.webm.mp4

Is there a way to get it to omit the webm in the filename?

I used it in the command.

I used the Mate Terminal.

Using @eriefischer's suggestion, it is best to create a script for this with the following content (Xfce's built-in interpreter can't handle special characters):

#!/bin/bash
ffmpeg -i "$1" -qscale 0 "${1%.*}.mp4"

...and make the script executable.

Then in the custom action command:

xfce4-terminal -x /path/to/script %f

Feel free to use mate-terminal but make sure the "-x" parameter is the same.

Re: Custom action to convert webm to mp4

Thanks ToZ, it worked like a champ. :-)

It's neat that I can see what the terminal is doing while it is converting the file.
