Neo Geo and Arcade not showing video previews - Steven Selph Scraper

flagrant99

I just got opposite results. Arcade Italia vids for mame only work with OMX Player OFF. Is it possible to update OMX Player to work with these?

@flagrant99 OMX Player is not really ours to update, and to the best of my knowledge it hasn't been updated to support that profile.

Read this bug in their repository.

Not supported. Pretty sure no hardware decoder (on any platform) will handle this.
It's not a consumer profile, it's for professional (studio) masters.
We support Blu-Ray quality video (4:2:0 with 8 bits per channel).
This is 4:4:4 with 12 bits per channel. See: http://www.digitalpreservation.gov/formats/fdd/fdd000218.shtml

You may try to update OMXPlayer on your Pi, but I'm not confident anything will have changed in that regard.

Your best option is to either use VLC, or re-encode them, as described in the previous posts.

Sorry about that.

I take it you have them downloaded and converted? I downloaded mine on my pc with Steven's scraper as the pi was struggling a little. I had an AWFUL time trying to run the ones from emumovies until I converted then down. (the scraper does that "on the fly")

Thx for the responses. You are correct looks like High 4:4:4 Predictive Profile will not play in OMX Player. They also will not play on my windows 10 desktop. Seems Most videos scraped from Arcade Italia are High 4:4:4 Predictive Profile. Most videos scraped from screen scraper are not and play fine in OMX Player for me. So I just re-scraped from screen scraper. Here's another interesting link on the many flavors of h.264.

Without OMX Player (Hardware acceleration) the High 4:4:4 Predictive Profile play fine as well.

@flagrant99 I see your problem now. I forgot I had used emumovies for my arcade.
Looks like the videos themselves come from Progetto-Snaps You can run them through handbrake and that will fix them.

Read this thread for converting.

I have the same issue NES, SNES, Genesis and Master System all work amazing

Images, Marquees and Videos all worked using Stephen Selphs scraper

The images, Marquees work for MAME but the videos do not play even though they downlowed during the scrape

WHen I turn off OMX the videos play good but they play very choppy for all the systems that worked perfect with OMX on.

@pjft what do I do in Handbrake to convert them so they work with OMX turned on?

Valhalla_Pi

@wombat can you please share what steps I do in HandBrake to convert the files proper

pjft

@valhalla_pi re-encoding then in one of their MP4 presets seemed to work for me. Ultimately they just need to be encoded in a compatible format, which the majority are.

Valhalla_Pi

@pjft thanks, just the default settings in Handbrake made them all work

one related question, if the scrapper missed a few roms and I found the videos, renamed them put them in the images folder

the games still dont work, when I go to the meta information for the rom the path for video is blank, do I have to manually type this in?

obviously the roms that scrapped using Stephen Selphs scrapper filled in the path for the video file but if I mannually add does that mean I manually update that video path?

akafox

Yes you will have to manually add this info. I would suggest working through filezilla or putty (windows or linux) then download a copy of the gamelist.xml to your hard drive on your PC. Make a copy of it somewhere. Then open it in your text editor. You can add the information by hand. Test by opening it in your web browser. If no errors pop up then copy it to the ~/pi/roms/neogeo folder.

Or you can use the ES gui to type it in by hand there. Either way works..done it MANY times. I even have info and snaps/vids for homebrews too.

I made my friend's list in the info for kirby's avalanche say that "you suck at this game so you are not allowed to play it! :P" yeah I'm bad lol

I've tried converting my arcade video snaps with Handbrake to no avail, is there a source in Steven Selph's Scraper with arcade video snaps that play well will OMX Player? It would be easier for me to just delete my video snaps and rescrape than to convert the ones I have.

akafox

Are you using the gui or the cli of handbrake? More on that with this thread:
https://retropie.org.uk/forum/topic/12590/how-to-properly-convert-video-snaps-for-emulationstation/24

As far as I know, no there is no other source for video snaps through the scraper. I got mine as a pack (as most do) and then converted those down. That was the only way I could get mine to work. I let the scraper build my list so all the video that were there deleted the videos the scraper brought down and converted my own down.

I guess you could convert the ones the scraper brings down too..it might fix them. I have still have my script somewhere I think...l I'll post it when i have the time.

I used another scraper.

@akafox I do let it scrape and convert them after. Any vids from progettoemma for mame or negeo are created with a codec that doesn't run on any standard system I am aware of. Strange if the MAME screen capture is doing this. Videos won't even run on Windows 10 in any player I tried until I downloaded a codec set that had the right one in it. Remember to set the option in handbrake to always use the MP4 extension so you don't have to rename them all from M4V.

I know this topic is quite old but I had the same issue with the latest version of es/omx/retropie so thought I would post, I ran the videos through a program call Mobile Media Convertor on Linux using the mp4 setting and the reuploaded and now they all work as expected

The arcadeitalia video problem with OMX, can easily be resolved by this ffmpeg command:
ffmpeg -i inputFile.mp4 -pix_fmt yuv420p outputFile.mp4

The process is fast and looseless.

In this way, we can continue to use the good arcadeitalia source.

akafox

I found that after scraping the neogeo games I could not use them in anything but my PC in my media player..so I ran then through handbrake and they worked great on my pi and in retropie for my pc and my raspberry pi (even attract mode)..but yeah I trashed the originals as they would not work

@akafox The problem is that some of those videos are in a format that the OMX player can't handle (mainly YUV 4:4:4 instead of YUV 4:2:0). But since only OMX player provides hardware accelerated video output at this time, switching it off isn't a good option for most people. Converting is a little inconvenience for a better result.

By the way, there at least two scripts here to batch convert only the videos that need converting, a simple one from myself and an advanced one from @hiulit.

Sorry for necromancing this post. But I just noticed the "-convert_videos" flag when scraping from the command line. Is this enough to fix the YUV 4:4:4 issue? It invokes the handbrake CLI.
