[SCRIPT] RetroPie Convert Videos

pianoman72

@hiulit Is there a way to force the script to look in a specific video directory? Mine are in /opt/retropie/configs/all/emulationstation/downloaded_images/arcade/

No, it's listed in the prerequisites that you have to use the ROM folder:

Use the ROM folder for gamelists & images option in Steven Selph's Scraper.

Use the ROM folder for gamelists & media option in Lars Muldjord's Skyscraper.

You could use Clyde's original script that this was based off of though; that one operates on a single directory at a time.

@sleve_mcdichael Thanks
Here is the old script updated to use ffprobe and FFmpeg if it helps anyone

mkdir -p converted                         # create the folder "converted" if it doesn't exist
for f in *-video.mp4                       # process all videos
  do
    c=$(ffprobe -show_streams $f 2>&1 | grep -c yuv444p) # (-c)ount no. of "444p"

    if [ "$c" -gt 0 ]                      # if 444p is present,
      then				   # convert into 420p
        ffmpeg -i $f  -y -pix_fmt yuv410p -strict experimental converted/$f
    fi
done

@pianoman72 I'll take a look to see if it's easy to implement :)

@hiulit Can you update the links in the OP as they changed over time?

Thanks

@Lolonois Done! Thanks for the heads up!

Re: [SCRIPT] RetroPie Convert Videos
I am not technical and honestly, github is confusing and scares me LOL but this script was EXACTLY what I needed thanks so much! My only recommendation is for absolute newbs like me to have an upfront callout that the steps are to:

Install the script
Run the program using those mandatory/optional items on the Pie
Manually update the video files using file explorer on a PC or other method

That last item was the only thing that stumped me for a little bit... was figuring out what to do after the conversion was successful. But your documentation does have it.. I just found it a little hard to find.

Thank you again, this was so helpful and literally was what actually let me consider my arcade build "complete because both the Mame and NeoGeo videos I had werent working, but now they are!

This tool does not seem to work with how skyscraper downloades images/videos to /home/pi/.emulationstation/downloaded_media/<system_name>/videos/

Any advice?

Forget this tool. I tried it to no avail. Just copy the videos on your Mac
, install ffmpeg with brew and run this script

#!/bin/bash

# Directory containing the original videos
input_dir="path/to/your/input_directory"

# Directory where the converted videos will be saved
output_dir="$input_dir/converted"

# Create the output directory if it doesn't exist
mkdir -p "$output_dir"

# Loop through all video files in the input directory
for video in "$input_dir"/*; do
    if [[ -f "$video" ]]; then
        # Extract the filename without the path
        filename=$(basename "$video")
        # Set the full path for the output file
        output_video="$output_dir/$filename"
        
        # Perform the conversion with ffmpeg
        ffmpeg -i "$video" -c:v libx264 -pix_fmt yuv420p -c:a copy "$output_video"
    fi
done

echo "Conversion complete. Converted files are located in $output_dir"

I've created post on how to convert these vids in Windows:
