Right you are! It was 444. I get access denied trying to put the .SH file in /usr/local/bin (WinSCP). How do I go around that?

That's a root ("administrator") folder so you need root access. I'm not familiar with WinSCP, but if you can't figure out root access there, then I would just drop it in /home/pi and finish up with SSH (or if you have a spare USB keyboard, you can plug it into the Pi and press F4 to exit EmulationStation and access the terminal.)

Win10 has an SSH client built-in. Just use the search bar and type:

ssh pi@retropie.local

(The password is "raspberry" if you haven't changed it.)

If this is your first time connecting over SSH (from/to this particular pair) then you may be presented with a "certificate." Accept the certificate.

At the command prompt (it will look like "pi@retropie: ~ $"), you should first set the executable flag on the file:

chmod +x "/home/pi/ScriptName.sh"

(Replace "ScriptName.sh" with whatever filename you chose. It's dirty practice to put spaces in filenames, but I wrapped the path in quotes just to be safe.)

Then, you can try to move the file with the mv command:

mv "/home/pi/ScriptName.sh" /usr/local/bin

...but you'll get the same "permission denied" error. So instead, preface that with sudo ("Super User DO"):

sudo mv "/home/pi/ScriptName.sh" /usr/local/bin

You wont receive any confirmation if it's successful; you will receive an error message if it fails.

Secondly, I am not sure what you meant by, call it from your media folders.

Just cd into the media folder and then type "ScriptName.sh":

cd /home/pi/.emulationstation/downloaded_media/snes/videos
"ScriptName.sh"

Since the script file exists in the system path and is executable and starts with #! /bin/bash, just typing its name from anywhere in the filesystem is enough to run the commands contained within it.

These commands will test every MP4 file in the current folder, and convert only the ones that are necessary.

The existing files aren't overwritten, new converted files are saved to a converted folder. To use the new files (overwriting the old ones; back them up first if you want), cd into the converted folder and move them one level up:

cd converted
mv *.mp4 ..

This only converted your SNES videos. You'll need to repeat this for NES, Megadrive, Arcade, etc:

cd /home/pi/.emulationstation/downloaded_media/nes/videos
"ScriptName.sh"
cd converted
mv *.mp4 ..
cd /home/pi/.emulationstation/downloaded_media/megadrive/videos
"ScriptName.sh"
cd converted
mv *.mp4 ..
cd /home/pi/.emulationstation/downloaded_media/arcade/videos
"ScriptName.sh"
cd converted
mv *.mp4 ..

...etc.

Don't forget to install the ffmpeg package, or the script won't do much when you do run it:

sudo apt update && sudo apt -y install ffmpeg

Pretty cool how easy that makes it. Something is not right though. I followed all the steps above.

-I have all media in a single directory /home/pi/.emulationstation/slideshow
-When I run the script in that directory, I see the shell output scrolling through every game
-A folder named "converted" can be found in the shell, but there is no content there running "ls". (Folder is not showing in WinSCP at all)

Test: does it work on this file? It's working on my end: https://www.progettosnaps.net/videosnaps/mp4/frogger.mp4

No that Frogger snap did not work, I do have one single video that works. I compared properties of the other files. See screenshot attached for comparison. World Games is the only one out of the many videos I have in the media directory that is working. Screenshot 2021-12-11 223334.png Frogger is the same copy you shared

I could backtrack to see where i got the world games video snap and look for others, but I found media packs at arcade punks and they include everything in the video selection! Id like to use this if possible.

sleve_mcdichael

@rasp_renegade clarification: you mean "works" as "plays in emulationstation" or as in "is converted by the script"?

That Frogger video won't play in ES, it's in the 444p format. I meant you should test it with the script, and see if it converts. Want to make sure you have that part right. I tested on my end, copy-pasting the text from my forum post into the script, placing it in my system path, and it did properly convert to the correct 420p format.

If it doesn't work on your end, something went wrong. If that video does convert, then we'll look at why the rest of yours aren't.

The script is working, but I have no idea where the converted files are going. A folder named "converted" is created, but no content inside. How can I check?

I found a swell program called HandBrake that converts these to a supported format. I doubled the frame rate in the settings. This works great, but id much rather be able to bash this!

You could try a find if they're still named right:

sudo find / -name frogger.mp4

But I have a feeling the script didn't copy correctly; if it's not using the right folder, who knows if it's using the right name.
To rule out copy-paste errors, does your script file have a crc32 of 8a51563a?

@sleve_mcdichael

No files were found running that command.

Any ideas?

Wait not even the original one you downloaded?

Any ideas?

Sorry, no. The above works for me on Pi 4, can't say why it's not for you. If you've:

Installed ffmpeg, and

Copied the script correctly, and

Made the script executable, and

Copied it to your system path, and

Your video files are in the yuv444p format (like that frogger one is), and

You run the script from the directory with the videos in it, and

It creates a converted directory but does not create any converted videos in it, then I am stumped, because when I have:

Installed ffmpeg, and copied that script, and made it executable, and put it in my system path, and ran it from the directory with that frogger.mp4 file in, then it creates a converted directory and puts a converted frogger.mp4 file in that directory.

Technology hates me so things such as this are my norm. =) Thanks for the help, you presented the actual problem and I will work on the script. I found a site that has all emu movies at the correct bitrate or whatever is off.
