[SCRIPT] RetroPie Convert Videos

Duel

1st of all great script. I converted all my videos with no problems. Question though, I'm getting an error when rebooting RetroPie. Illegal-Mpeg-Header . Here's a picture of the error code. https://www.dropbox.com/s/whgj075huoke8u6/img_20211201_075232.jpg?dl=0. Can you tell me what this means and how to fix it?

Nevermind on this error. I've rebooted instead of restarting emulation station and the error went away. Thank you for this script. I've looked everywhere to find a fix for video snaps for MAME to play properly and this was it. Major props.

@duel Hey, I'm glad you find it useful :)

@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 :)

@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"
