YAD and Zenity - Input Start/Stop Times to Trim Video

I have a bash script and a php script that function in concert to [trim audio/video files using start/stop times](https://unix.stackexchange.com/questions/182602/trim-audio-file-using-start-and-stop-times) . PHP script: format('U') - $dt1->format('U'); // echo $dt3."\n"; $h = (int)($dt3 / 3600); $dt3 %= 3600; $m = (int)($dt3 / 60); $dt3 %= 60; $s = $dt3; // Dump as H:M:S echo $h . ":" . $m . ":" . $s; ?> chopvideoaudio.sh script: #!/bin/bash INFILE=$1 START=$2 STOP=$3 OUTFILE=$4 OFFSET=php TimeDiff.php "$START" "$STOP" echo "Disecting $INFILE starting from $START to $STOP (duration $OFFSET)" ffmpeg -ss "$START" -t "$OFFSET" -i "$INFILE" "$OUTFILE" Usage: ./chopvideoaudio.sh [input.mp4] [startchop] [stopchop] [output.mp4] Where [startchop] and [stopchop] are both absolute timestamps from the beginning of the track. Example command to run this script:

./chopvideoaudio.sh input.mp4 00:01:20 00:01:45 output.mp4

I want a [YAD (yet another dialog)](http://sourceforge.net/projects/yad-dialog/) script that will open up a dialog box(es) containing an input field to enter a custom file type (e.g. mp3, mp4, avi). Then input fields for the two timestamps, in which I can enter two custom timestamps. After pressing OK the script will run and extract the section from between the two timestamps. I would also be interested in a solution using [Zenity](http://www.linux.org/threads/zenity-gui-for-shell-scripts.5567/) , but I prefer YAD.
