@mitu

Looks like the Nvidia driver I had installed was the culprit. I removed it and used the Nouveau one and Emulationstation now starts but launching games fails. I am troubleshooting further.

@mitu good day!
I was testing some mame video snaps on retropie.
Im well aware of the new default being VLC and that retropie is moving away from omxplayer.

On my system, video snaps from same source, some play ok some other not. They produce the blackscreen as per this post.

In VLC settings ffmpeg HW acceleration is disabled in codecs section. I cant find yet what is VLC missing and cant paly these files.

This is on a pi4 2GB model with latest updates and retropie.

For testing im providing this small 900KB argus.mp4 video snap
https://mega.nz/folder/2HAxmYJR#nNsMz6pZDkn1T36ASe5ZCg

I have on my system also installed the MPV. This one works great on all problematic video snaps.
VLC requires re-encoding of the files to work ok

Here is my testing from command line
MPV

And running the re-encoded (as per above) video snap, which now vlc can play OK!

@huey no, let me check it

I have it on a Raspberi pi 4 with retro pie 4.6

Re: Looking for log/clue why ES video screensaver may get stuck w/black screen

Closing the thread on this. There is nothing wrong with the randomizer. While there was exactly one (1) "Little Computer People" video, there were ~100 variations of the game in the XML referencing the same video. So it's probably by design. It would seem that each game listed in XML with a valid video has the potential to play. Like throwing 100 tickets into a casino raffle drum... You're more likely to win.

Ideally each video found should act as 1 potential. Not a big problem, but since games with multiple variants that reference the same video are more likely to play, making things seem less random than they truly are.

Mystery solved after spending way too much time staring at random videos.

@WedgeStar said in 3 quarter black screen:

@YFZdude It is similar, it has also happened with games that don't have overlays, resetting works sometimes but not very often. sounds like I'll be just waiting for a update. Thanks for your Time

This stopped happening to me when I updated retropie setup to it's latest version "X.X.7" forgot the number but after you are on that version only use retroarch from BINARY and open retroarch in retropie setup.. make sure it is on version 1.8.8 and you shouldn't get this issue anymore.

@doubleup_dan said in Black screen after overclock with argon40 case:

So I have installed a damasos nostalgia trip 200gb and my pi4 4gb is in an Argone40 case and it has been mostly running fine.

We don't support 3rd party images - it's clearly stated in https://retropie.org.uk/forum/topic/3/read-this-first. Start with the image from retropie.org.uk/download if you wish to get support here in the forums.

@TheMaguffin https://github.com/midwan/amiberry/issues/671

It's already been fixed (According to author).

@Chapster5 Thanks for sharing your solution. 👍

You didn't mention how installed RetroPie.

@mitu That didn't seem to work unfortunately. BUT after getting another batch of ROMs I was able to get them working! Not sure what was happening with the other ROMs since they worked on my PC but these ones seem to work fine. Hopefully I don't have any further issues.

Thank you for the help!

If you have a 4k tv/monitor, then use raspi-config and change your default video resolution to 1080p.

Answered my own question. So my workstation has 3 monitors and a TV, the pi had this issue with the TV and one of them monitors. Works absolutely fine on the other 2 monitors though, and the TV in my living room where this was going to go anyways works fine with it as well.

Anyone know why this issue is occurring?

You should add a proper title for your topic - just saying Help in a Help and Support category is meaningless.
Take a look at https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=58151#p1485558 to diagnose boot problems. Look at the LED flashing patterns on your Pi and compare it to the diagnose info posted in that forum post to see where the boot stops.

@mitu Hey mitu! Thanks for the suggestions. I figured it out after - I simply tried plugging it into a TV instead of my monitor, and no issues - I can see everything just fine. I think I had the wrong resolution settings perhaps, or maybe it was something to do with the high refresh rate. Regardless, thanks!

it sounds to me like the .cue is bad and points to a file that doesn't exist. you could either acquire a different rip or attempt to create a new .cue (see https://retropie.org.uk/docs/Playstation-1/#bin-only-roms)

@Clyde said in Subtitles error with OMX Player on Pi 4 with RetroPie 4.6:

Two more questions, does VLC have HA "just like that" or do I have to activate it somehow?

No, hardware acceleration is used by default.

And does OMX have any advantages left over VLC?

Yes, it's still faster than VLC with HW acceleration in EmulationStation.

Retroarch 1.8.7 has been released yesterday, hopefully this issue is fixed now.
