Zenity progress: no window

Question

Bit of a noob question, I know...

I want to batch convert my videos to h265, which I can do with the help of Zernity and ffmpeg, but I'm having a little problem with the progress bar, in that there isn't one.

The actual "meaty bit" works wonderfully, with or without the last part, which is:

zenity --pulsate --title "Processing " --text "${filename} " --pulsate --auto-close --auto-kill

The whole code is:

d1="$(zenity  --file-selection --title="Bulk Move    Choose starting directory"  --directory)"
d2="$(zenity  --file-selection --title="Bulk Move    Choose destination directory"  --directory)"
if [ "$?" != 0 ]; then
   exit
fi
##
for i in "$d1"/*
  do
## filter out the actual file name
  filename=$(basename -- "$i")
## the meaty bit
ffmpeg -i "$i" -c:v libx265 -preset medium -x265-params crf=28 -c:a aac -strict experimental -b:a 128k "$d2"/"${filename%.*}.mkv" ; done | zenity --pulsate --title "Processing " --text "${filename} " --pulsate --auto-close --auto-kill

The only way I know it's working is by either calling the script on a command line and watching the ffmpeg (very verbose) output, or monitoring CPU usage.

Can someone point me in the right direction?

Thanks

You aren't checking if the starting directory was aborted only the destination directory. Also you can shorten if - then - fi like this:

d1="$(zenity  --file-selection --title="Bulk Move    Choose starting directory"  --directory)"
[[ "$?" != 0 ]] && exit
d2="$(zenity  --file-selection --title="Bulk Move    Choose destination directory"  --directory)"
[[ "$?" != 0 ]] && exit

This gives double the amount of abort checking with 1 less line of code.

To test the progress bar on any system use this:

$ for i in ./* ; do echo $i ; sleep .1 ;  done | zenity --pulsate --title "Processing " --text "${filename} " --pulsate --auto-close --auto-kill

--pulsate is not supported for this dialogue

Ah there is an error message! --progress is missing to tell zenity a progress bar is desired. So the working script would be:

d1="$(zenity  --file-selection --title="Bulk Move    Choose starting directory" \
    --directory)"
[[ "$?" != 0 ]] && exit

d2="$(zenity  --file-selection --title="Bulk Move    Choose destination     directory" \
    --directory)"
[[ "$?" != 0 ]] && exit

for i in "$d1"/* ; do

    ## filter out the actual file name
    filename=$(basename -- "$i")
    ## the meaty bit
    ffmpeg -i "$i" -c:v libx265 -preset medium -x265-params crf=28 \
        -c:a aac -strict experimental -b:a 128k "$d2"/"${filename%.*}.mkv"

done | zenity --progress --pulsate --title "Processing " \
              --text "ffmpeg - convert files" \
              --pulsate --auto-close --auto-kill

Passing ${filename} to --text option will not update display with each file name processed. If you want this you will need to switch to yad (Yet Another Dialog) which is a super-charged version of zenity:

Although the source code appears in the .gif you can copy and paste in your own script from this Q&A:

How do I create a fake process bar?

Thanks for your help.
It works very well, except the filename doesn't come up.
2 pulsates?
Your extra bit about testing a progress bar is interesting in that maybe I could use it to show percentage of files done, instead of pulsate. — user256787, Oct 18 '19 at 15:08
@user256787 I've added filename handling the only way I know it can be done. Also percentage complete has been added which you can still use in zenity if you like. — WinEunuuchs2Unix, Oct 20 '19 at 13:40
Tried yad. Promising, but the filename scrolls off the "current filename" immediately, and its window is only one line high. — user256787, Oct 22 '19 at 12:55
Sounds like --log-height=250 is missing or incorrect. You can post a question on this problem if unable to fix. — WinEunuuchs2Unix, Oct 22 '19 at 15:02
