Realtime Dialog boxes in Bash Scripting

I would like to try and push the output of FFMPEG and HandBrake into a dialog window using the dialog command.

I noticed there is a tailbox option but I cannot find much information on how to use this.

Does anyone have any examples I could work off?

I thought maybe using something like the below would work. But it doesn't.

ffmpeg -i 02.ts -acodec pcm_s16le -ac 2 02.wav | dialog --title "Extracing" --tailbox 10 75

What would be the best way to this to create something like this?

Tailbox requires a file parameter. So you'll need to do one of the following:

ffmpeg -i 02.ts -acodec pcm_s16le -ac 2 02.wav > outfile &
dialog --title "Extracing" --tailbox outfile 10 75

dialog --title "Extracing" --tailbox <(ffmpeg -i 02.ts -acodec pcm_s16le -ac 2 02.wav) 10 75

In the first case, you may need to use `mkfifo outfile` then change the > to a >>.

EDIT: wait, why are you trying to use tailbox? Progress box is exactly what you want.

Hmm.. I see that it just spews out of the box and doesn't following the box's width or length. That is a shame Back to the drawing board.
