[SOLVED] - Video Snaps not Playing

mitu

@hyuma Check if

You're using omxplayer for video previews, should be an Emulationstation setting.
The theme you're using has video preview support and the Gamelist View Style is set to video in the Emulationstation UI Settings.

Just got in gang, thanks for the replies, I'm going to test now and post in a few minutes the results.

Hyuma

@mitu yes i have both, but as I said video preview works but not all preview are working and i'm trying to understand why..

mitu

@hyuma What theme are you using ? If you play the video from the CLi with omxplayer <video_file> do you get any errors or the playback is ok ?

Hyuma

@mitu I tested various theme also with basic theme i had the problem, now I'll try that command to see which error i get. ;)

Hyuma

@mitu running from terminal

omxplayer input.mp4

Video codec omx-h264 width 480 height 360 profile 100 fps 29.970030

I got no error

Here's the update.

First tried changing the OMX hardware acceleration ("Other Settings">"Use OMX Player (HW Accelerated)"), same result on or off, video snap preview doesn't play.

Second attempt was the re-encoding. File size doubled, so something changed, result was the same however, snap video didn't play.

Third attempt was based on @mitu suggestion to play on CLI using omxplayer command. Both the original (_orig.mp4) and the new (ffmpeg converted) files played. Here are the outputs:

pi@retropie:~/RetroPie/roms/mastersystem/snap $ omxplayer Ace\ of\ Aces\ \(Europe\).mp4
Video codec omx-mpeg4 width 320 height 240 profile -99 fps 30.000000

V:PortSettingsChanged: 320x240@30.00 interlace:0 deinterlace:0 anaglyph:0 par:1.00 display:0 layer:0 alpha:255 aspectMode:0
have a nice day ;)
pi@retropie:~/RetroPie/roms/mastersystem/snap $ omxplayer Ace\ of\ Aces\ \(Europe\)_orig.mp4

pi@retropie:~/RetroPie/roms/mastersystem/snap $

Side note, I did have to use @Hyuma command ffmpeg as the avconv alias wasn't there. It seemed to work fine.

So still kinda scratching my head, gamelist.xml file looks correct to me, file is there, encoding seems okay, plays from CLI with omxplayer...This is very odd and I hope we can figure this out.

let me know what else we can try.

@wiggy808 do you use chat like irc or discord? we can talk there if you want to

wiggy808

Yes, I'm on discord, how do I message you my name without posting it here, lol

wiggy808

@Hyuma I guess its not that big of a deal. My discord name is same as it is here, wiggy808

Hyuma

@wiggy808 i need also the numbers after the "#" in nickname

@wiggy808 @Hyuma As a word of advice, it may be suboptimal to move your discussion to a private chat, because others can't follow and thus, can't provide any additional counsel.

That said, it would be nice if you'd provide us with any insights in the matter, no matter if success or failure, since both can be educational.

@clyde I agree! It was more as an easier way to test somethings in a live manner. It was just today that we figured it out after some testing.

It was DEFINITELY a scraper / gamelist.xml issue!

It appears that the gamelist.xml file in the /home/pi/.emulationstation/gamelists/mastersystem was causing some issues as it conflicted with the one in /home/pi/RetroPie/roms/mastersystem. I deleted the one in .emulationstation and began to manually edit the one in RetroPie (Ace of Aces rom and snap file names didn't match, that was another issue caused by either the scraper or something else that I had done).

However, after making changes and rebooting, the gamelist.xml in the RetroPie directory reverted back to the original syntax it had before I made the changes. So we decided to shut down ES, edit the file, then start ES back up. This worked and the changes are persistent and the previews began to show!

Couple questions:

How did the gamelist.xml file in the .emulationstation directory get created?
Why did the gamelist.xml file in the RetroPie directory revert to the original syntax? Is shutting down ES the only / best way to change that file?
What is the best / recommended way to produce a gamelist.xml file?

@wiggy808 said in Video Snaps not Playing:

How did the gamelist.xml file in the .emulationstation directory get created?

This is where it's created by default, so it was probably created the first time you copied the ROMs in mastersystem folder and restarted Emulationstation.

Why did the gamelist.xml file in the RetroPie directory revert to the original syntax? Is shutting down ES the only / best way to change that file?

Because that's how things work - Emulationstation generates a gamelist.xml file if there are ROMs in the folder and no previous gamelist.xml file was found. The file is written by Emulationstation when it restarts/stops, so any external modifications to the file while Emulationstation is running are more likely to be overwritten.
Note that if there is a gamelist.xml file in the ROMs folder, Emulationstation will not create a new gamelist.xml file in ~/.emulationstation, but it will use that file for further edits/changes.

What is the best / recommended way to produce a gamelist.xml file?

Use a scraper - either the built-in Emulationstation scraper or another scraper which understands and produces the Emulationstation gamelist.xml format.

@mitu Going to put this as resolved, thanks for the explanation as well!

I don't seem to have that option...help, lol

Clyde

@wiggy808 Thanks for the summary of your solution. :)

Usually you edit the title and add/prepend Solved/Resolved.

wiggy808

@mitu Under Topic Tools, I can only Delete Topic, no option for editing title... sorry, trying but not intuitive yet.

Clyde

@wiggy808 There really is no "Edit" entry under "Tools", right above "Delete"? That would be strange.

Mind that here's no separate "Edit Title" entry, you edit the title with the whole post.
