[SCRIPT] RetroPie Convert Videos

@hiulit Wow, thank you! I’ll give that a try ASAP (might be the weekend, as work has gone a bit silly 😔)

Thank you again!

[AbbaTheHorse]

@hiulit Hey, just tried the new version and it worked great! Thanks so much again 👍👍

[hiulit]

@AbbaTheHorse Yay! I'm glad it's working! Everyone can benefit from spaces in folder names now :)

@hiulit Some hardcore *nix users like a friend of mine like to express the opinion that spaces don't belong into filenames because they are ticking time bombs waiting for the next application that can't process them properly. 😉

[hiulit]

@Clyde I'm with you. I don't like them either. But hey, if some user needs something and I can make it work without that much of a hassle, I'll do it :)

Thanks @hiulit very nice script! However I'm still having some trouble with videos playing. As per the usual it is only with the arcade video previews. I had gone through my list of arcade games scraped with skyscraper that didn't play back and wrote them all down to try and fix. I eventually came across this script online. I used your excellent documentation and setup as follows.

--from -ces set to "yuv444p"
--to -ces set to "yuv420p"
--scraper set to "skyscraper"

Then I ran the script. Sure enough! it found all the ones I had written down and proceeded to convert them. I thought for sure it would fix the playback problem but, they still don't play :( I've tried playing them back with omx hardware acceleration and without, and neither work.

Any ideas? I can try to provide more information from the video files, but don't know what to provide. Thanks!

I'm running a raspberry pi 4, 4GB, on Retropie 4.7.1, with official raspberry pi power supply.

As is so often the case with not reading documentation fully, I had missed the part where the converted files would be in a new folder and have to be manually copied to the original folder and replace the old files. As soon as I did this it worked like a charm. Wow excellent script, much thanks!

[hiulit]

@lemonlimefx Thanks! I'm glad you find it useful! :)

It's not the first time that someone has had this confusion. I think I'll have to tweak the script to add an option or something to let the user overwrite the old video files, at their own risk.

@hiulit hello, is there a step by step video on how to do this? I am new to this and really eager to learn. Thanks

[hiulit]

@colombia20102018 No, there is not at the moment but I'll try to make one when I have the time :) What are you struggling with? Have you read the documentation? I think is clear enough for a "noobie"

Hey @hiulit I just wanted to thank you for your handy script.

I had a slight issue with the step listed as "--to-ces [OPTIONS]` (mandatory)" where it said to run 'ffmpeg -pix_fmts' and I didn't know what to do here but then I rebooted and the previous command worked for some reason. Lastly I had to manually edit my gameslist.XML files to include the videos for each of the games in order for the videos to show but that's probably just down to me at some point doing something I probably shouldn't have or not doing something I should have :) Works great, thanks again!

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

[hiulit]

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