      @Darksavior yeah Qt can be quite complex, and not necessarily the best first time experience :) I've never seen that error before, but you could try using this Qt build I've made. I'll also set up an automated nightly build system tomorrow, so you won't have to rebuild every time there's a change.

      (Also the PPA you linked provides desktop Qt, which is why it will not run on the Pi.)

        Ok, the very latest builds are now available here, and are updated on every new commit of the master branch.

          Could it be possible for Pegasus to have an overlay-option for some games, or will overlays work the way it does today?

          In non-coder terms, what's the current status of this project?

            @fluffypillow let me know if you'd like translations to danish - I'd love to contribute in some way, but I guess other languages is pretty low-priority.

              @AndersHP by overlay, you mean a global GUI overlay that would pop up when you press a key/button combination? Like with Steam, Kodi, and on consoles? I'm not sure if it'd be possible on the Pi, (as far as I know) when you're running an emulator, it owns the graphical context of the device ("has the right to draw on the screen"), and I don't know if it's allowed for other programs to draw at the same time. It probably could be done on desktop/X11 though.

              In non-coder terms, what's the current status of this project?

              What counts as a non-coder term? :) It's currently in Alpha, meaning some functions are usable, but many are missing, there could be lots of bugs, and the documentation is lacking. In short, it's incomplete but testable.

              Danish translation

              Sure, translations are welcome! I'll write up a localization guide (there's even a nice GUI program for it), and translation context comments; meanwhile you can find the Hungarian files here. The changes and new files will be automatically picked up by the build system (well, as soon as I finish translation support). It's not necessary to translate every text, eg. console debug output messages, it'll fall back to English. Also since it's still in alpha, the text may change often, eg. when new features added and such.

                No I think that would stress the Pi unnecessarily? I meant MAME overlays like bezels for vertical shooters etc. But maybe that's too early when the basic functionality is not 100% yet.

                  When I browse with videos from screenscraper.fr's, pegasus eventually crashes. Bit of lag when browsing but when I downgrade them to 320x240 with sselph's scraper + handbrakecli.exe, some videos appear garbled for some reason. They play fine in ES.

                  Error message(I tried the original 640x480 videos)
                  Gstreamer-WARNING **: gstpad.c:4661:store_sticky_event:h264parse54:src (and capsfilter54:sink) Sticky event misordering, got 'segment' before 'caps'
                  and a lot of "warning: "no volume control found""

                    (You may have already said this before but) what video player does Pegasus use? I think ES was using the VLC player but I believe they've moved over to the OMX Player with hardware decoding? That might be why @Darksavior's videos "appear garbled".

                      @AndersHP ah ok, but isn't that a libretro setting?

                      @Darksavior @backstander Pegasus uses the Qt Multimedia module, which in turn uses GStreamer (1.0) on Unix. Video format support depends on the quality of the GStreamer plugins, but most of them seem to be in a bad shape...

                      In theory, installing gstreamer1.0-omxshould enable hardware acceleration, but that's probably not enough to fix the video output. I have some ideas that could be tried out:

                      • I've heard there's a plugin that enables GStreamer to use FFMPEG, might worth looking into it
                      • I wonder if using a freshly built GStreamer using the latest version would improve things; this would also require rebuilding Qt and Pegasus
                      • There's someone who used OMX directly in Qt, without Multimedia; maybe we could too

                        This week the translation support has landed:

                        • implemented the settings menu
                        • implemented dynamic translation reload on language change
                        • build system integration
                        • translation guide

                          RetroFE also uses gstreamer. If you can link me a garbled video I can check if it plays on there. If it does, it's either a plugin issue or you might be able to find an answer in the RetroFE code.

                            @phulshof thanks, personally I had some problems (eg. "stripes") with the videos from here: https://github.com/mattrixk/es-toolkit-videos

                              I'll have a look. Do you have a screenshot of what garbled looks like?

                                @phulshof @fluffypillow I'd love to learn more about gstreamer, why you chose it, advantages and disadvantages, as well as how it's actually used in the code to render videos.

                                I don't want to sidetrack this thread, though. Would you mind if I start a new thread and tag the two of you about it tomorrow or Thursday?

                                Thanks.

                                  @phulshof This is mine made from sselph's scraper and handbrakecli.exe
                                  I'm not sure what settings he's using but it doesn't happen with every video converted, but it 100% happens with the same games.

                                    That's fine. 😀 I can tell you how it's used, but I have no idea why Emb chose this library over other ones to be honest.

                                      I'll give it a try tomorrow, and let you know.

                                          FYI This is how my code is transcoding the video. I didn't write this so not sure exactly what it does but here is a rough equivalent command
                                          HandBrakeCLI -i <input> -o <output> -e x264 -w 320 -l 240 -r 30 --keep-display-aspect --decomb --audio 1 -B 80 -E av_aac

                                            I'll need some more input here; this doesn't look like a command for the pi, and if it is then I don't know where to find scraper.exe (sounds like Windows) nor handbrakecli.exe. The ES videos you linked to don't contain Alien 3 for the SNES, so I cannot test it from there either. :( Any chance you could simply put the result video on dropbox or something similar for me to download?
