      @wiggy808 Okay, the most common reason for non-working videos isn't the case here (yuv444 instead of yuv420, because ES' hardware-accelerated OMX player only plays the latter).

      Yes, the VLC errors are still interesting, too. My post was meant to check on both the errors and the encoding.

      edit: Does it change anything if you turn hardware acceleration in Emulation Station on or off? ("Other Settings" > "Use OMX Player (HW Accelerated)")

      edit 2: You could try to reencode the video without any changes to its codecs to see if it plays then. It may correct any errors we don't see in the stream info.

      avconv -y -i input.mp4 output.mp4
      

      Change "input" and "output" to the resp. paths+filenames.

      (From Retropie 4.4 on, avconv was replaced by ffmpeg, but it remains as an working alias, so I still use it for backwards compatibility with RP 4.3 and before.)

          i've resolved with this command:

          ffmpeg -i input.mp4 -vf format=yuv420p output.mp4

          than i re-upload the video inside media/vidoes

            @hyuma Were your videos already in yuv420p before the re-encoding? I'm asking because @wiggy808's videos are in yuv420p, and still some of them won't play.

              I won't be home until tomorrow, but I did see your reply @Clyde and will try it and let everyone know. Hopefully changing the hardware acceleration does something, we will see. I'll try the reencode as well, it would be interesting to see what @Hyuma says about the original state of his vids.

                @Clyde my video were yuv 4.4.4 and after the conversion they became yuv420p. To check if all was good use the command:

                ffprobe -v verbose input.mp4

                I've noticed that i still have 2 videos that doesn't work also after the encoding and i'm thinking it could be a VBR video codec issue but i'm not sure...

                  @hyuma Thanks for the information. Yuv444 is a known problem for OMX player. There are at least two scripts to fix that for multiple videos, one by myself and one from @hiulit.

                  But @wiggy808's videos are already in yuv420p (at least the Ace of Aces video is), so alas, it's not that issue. I'm curious if re-encoding his/her videos will change anything.

                  Let's stay tuned. :)

                    Wow, good job with the script, @Clyde! I still have 2 mp4 that doesn't work also in yuv420p and i can't understand why... Here you can find the media information of video:

                    https://paste.ofcode.org/JfKAGPpCB7EJg7vtYkC7Az

                    if you can tell me why this video doens't work you will be very helpful for me! thanks

                      @hyuma Thanks for the compliment. My script isn't nearly as sophisticated as @hiulit's, but it does its job in the spirit of the Unix Philosophy #1, "make each program do one thing well". 😊

                      Alas, I can't say much about your media information, as I know next to nothing about video internals. But maybe someone else here can.

                      That said, did you compare the media data of the non-working videos to that of the working videos? That may give away some clues.

                        yes I've compared and the only difference comes from VBR against CBR... but the videos working as screensaver... only in preview they doesn't work...

                          @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.

                                @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 ?

                                      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
                                      Audio codec aac channels 2 samplerate 48000 bitspersample 16
                                      Subtitle count: 0, state: off, index: 1, delay: 0
                                      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
                                      Video codec omx-h264 width 320 height 240 profile 100 fps 30.000000
                                      Audio codec aac channels 2 samplerate 48000 bitspersample 16
                                      Subtitle count: 0, state: off, index: 1, delay: 0
                                      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 $
                                      

                                      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.
