Selph Scraper Video Previews not working - yuv420p vs yuv444p?

[nerevarine]

Was this issue ever resolved? When I had a Pi 3b, video previews were never an issue. Now I have a 4b and I'm trying to replicate the video previews, however, a vast majority do not work. All I have learned is that the most likely culprit is the video files. I've had this issue since January 2021. Struggling because it was one of my favorite aspects of my previous emulator. Not excited by the idea of needing to pull all the files and convert them - I'm not sure how I'd accomplish that?

Put this in your /usr/local/bin folder and make it executable with chmod +x <filename>. Run it from your video folder. Your video files will not be overwritten. New files are saved to ./converted; to use them, you must move or copy one level up to replace the original files. Repeat for each system.

You may need to install ffmpeg first with sudo apt update && sudo apt install ffmpeg.

#! /bin/bash

mkdir -p converted    # create the folder "converted" if it doesn't exist
for f in *.mp4        # process all videos in the current directory
  do
    echo "$(pwd)/$f"  # show the processed file's name
    c=$(ffprobe "$f" 2>&1 | grep -c yuv444p)  # (-c)ount no. of "444p"

    if [ "$c" -gt 0 ]                         # if 444p is present,
      then                                    # convert to 420p
        ffmpeg -i "$f" -y -pix_fmt yuv420p -strict experimental converted/"$f"
    fi
done
