@Flexo55 Good you did find the cause. Please, as a courtesy to other users of this forum, do edit your first post and add to the subject something like [solved].

@mitu Actually, it's a lot quicker with omxplayer disabled. Are there any actual benefits to having it enabled?

UPDATE: Seems that a lot of clips only play audio

@Spudmckenzie Make sure you un-commented the password/username entries you added, they're commented (# at the beginning of the line) by default.

Thank you @mitu. I would never have guessed that setting controlled it. Works like a charm.

@mitu That's beyond my expertise... For another day perhaps.

@Deltax5 said in retropi doesn't show video but sound works?:

Looking thru the folders using WinSCP i noticed skyscraper is located at /opt/retropie/configs/all/skyscraper/
Do i just copy the the cache folder and copy it to a new image when the time comes? will that work so i don't need to scrap them. Or do i put it in the import folder? It will save time then rescraping everything.

You should really read the docs on Skyscraper - especially the part about the cache.

@njscorpio

I am having the same issue as you, all was working fine prior updating to 4.5. However if I enable OMX player it makes no difference, in face it is worst as no videos play.

This issue for me is only related to Mame preview videos. Everything else works fine.

I might try downloading the mame videos again, but does anyone have any idea what the issue could be?

@chubsta Anytime. Something else that may be useful to you is adjusting the crf value, sometimes called constant quality. A setting of 22 is usually default but that will make large videos that look good full screen, if its just going to be in the corner of your theme you may want to go with a higher value. I use crf 28 (the higher the value the lower the quality) This brought ~100gb worth of videos down to just over 32gb

@mitu @GoldManSex778 - Thanks for the advice. I converted with handbrake, basically opened the video in h/b and ran it through without messing around with the settings.
Now both the portrait and landscape videos display with the correct aspect ratio and work with omxplayer
Thanks so much.

@John_RM_70 said in slow, scratchy video previews on CRT but not HDMI:

audio_pwm_mode=0
disable_audio_dither=1

Yes that appears to fix things, addressing the root cause, which is the bug I linked to above. Thanks.

@mitu Ah, ok. :)

@grant2258 Thanks!

You can, but only if you use the default video player. OMX does not support layers and will be always the top most element.

@mitu - Thanks for the link. I added the system environment variables mentioned in the ARCH wiki and verified the were set and showed up using vainfo. VLC itself still was accelerated (~30% CPU), emulationstation was still not @~165% cpu

@mitu again you rock!!

After watching the video in your link, I found where I needed to turn off the OMX Player. (even though he syggested it be on) It is off and now I see the video preview!!! Love it. Thanks a lot. I still do not see <video> tags anywhere though.

@cosmicarcade that's probably related to the theme you're using, and you should look into the theme for details on what video it's using as the default one. Still, what @mitu said.

Ok, thank you

I was able to solve this by editing the theme.xml file in the hurstyblue folder.
