      @herb_fargus This all sounds great. Especially recording at the native resolution. Leave it up to people how they mess with the files' end result.

        also just as a note, of course the first thing I would pick would be annoying. There seems to be a bit of a heated debate as to what is defined as "native resolution" eg: https://github.com/libretro/RetroArch/issues/2837 but I suppose we'll just leave that up to the user and/or code maintainers for each core.

          @herb_fargus There's no such thing, as you know. The PC Engine has 3 "native" resolutions, I believe. There is not even a standard aspect ratio. A lot of consoles had 8:5 AR expecting stuff to be hidden behind the bezel. You'll never please everyone.

            @herb_fargus I started that guide and then got distracted by real life issues... But I remember that my first idea for improvement was to store the compiled ffmpeg in a github repo. One for each version of pi (or maybe one for pi1/zero and other for pi2/3). I'm not sure if it has some legal problem, but it sure would be valuable.

              @meleu it is possible ffmpeg will be in the stretch repositories, which should simplify the process a bit. I don't know the legalities of distribution but I vaguely remember ffmpeg being more restrictive

                Ok. quick update. I am basing my approach off of method one on the take and scrape your own screenshots guide. This is all assuming that people have ffmpeg compiled and retroarch with ffmpeg support compiled as well. The idea is to have an onstart script that will create all the video configs, runcommand configs, and folders for scraping. To lay out my basic idea:

                • Create a videos folder in each rom folder so that it is portable ie when you transfer your roms your scraped data and videos go with you /home/pi/retropie/roms/<system>/videos I've added functions so the video file will be named based on the rom name (I also have a date variable that can be added if one is creating multiple videos)
                • Create the ffmpeg config /opt/retropie/configs/all/retroarch/videos/config.cfg uses iniset so its simple enough to modify any of the fields if you want to change codec configs
                • Have a function based on https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/helpers.sh#L1125-L1181 that will generate recording configs for each core to be launched from the runcommand menu, though I wonder if it might be possible to see if there is some mechanism for starting/stopping recordings with a hotkey

                Once all the configs are generated by the script, again like the screenshot guide, we can then use sselph's scraper to add the video tags in our xml to match the newly created movies.

                Here's the preliminary script, guaranteed to be filled with bugs as its incomplete but I'd be happy to get any input for improvements.

                #!/usr/bin/env bash
                
                system="$1"
                rompath="$3"
                usbdir="/media/usb/RetroPie/roms/$system/videos"
                sddir="$HOME/RetroPie/roms/$system/videos"
                configdir="/opt/retropie/configs"
                vidconfigdir="$configdir/all/retroarch/videos" 
                
                rom_file="${rompath##*/}"
                rom="${rom_file%.*}"
                date="$(date +%Y-%m-%d-%H%M%S)"
                video="$rom.mkv"
                
                # Create videos folder in each respective rom folder
                #mkdir -p "$usbdir"
                if [[! -d "$sddir" ]]; then
                    mkdir -p "$sddir"
                fi
                
                # Create video config file for ffmpeg $vidconfigdir/config.cfg
                
                source "/opt/retropie/lib/inifuncs.sh"
                
                if [[ ! -f "$vidconfigdir/config.cfg" ]]; then
                 iniConfig " = " "\"" "$vidconfigdir/config.cfg"
                    iniSet "format" "matroska"
                    iniSet "threads" "3"
                    iniSet "vcodec" "libx264rgb"
                    iniSet "video_preset" "ultrafast"
                    iniSet "video_tune" "animation"
                    iniSet "pix_fmt" "bgr24"
                    iniSet "video_qp" "0"
                    iniSet "acodec" "flac"
                fi
                
                #if lr- copy lr and append video prefix to copied lr- and then append --record AND --recordconfig after .so, still needs tweaking
                if ! grep -q "recordconfig" "$configdir/$system/emulators.cfg"; then
                    sed -i -e '/^lr-/ p' -e '/^lr/s=^=video-=' -e 's@.so@.so --record '$usbdir/"$video"' --recordconfig '$vidconfigdir/config.cfg'@g' "$configdir/$system/emulators.cfg"
                fi
                
                ###This is currently not complete, but this will add the correct launch perameters to retroarch
                # Create lines in emulators.cfg for the emulator you are using to enable video recording with --record and --recordconfig:
                #if [[ "$id" == lr-* && "$cmd" != "$emudir/retroarch/bin/retroarch"* ]]; then
                #    cmd="$emudir/retroarch/bin/retroarch -L $cmd --record $usbdir/$system/$video --recordconfig $configdir/config.cfg --config $md_conf_root/$system/retroarch.cfg %ROM%"
                #fi
                
                #--record $usbdir/$system/$video
                #--recordconfig $configdir/config.cfg
                

                I thought I would have options for and sd card directory or a usb directory but tbh if people have mounted their usb correctly the path should be the same...

                The main issues I see right now is it hates spaces in the --record filepath and possibly parentheses too. I also need to find a mechanism so that the rom name is dynamically changed each time a new game is loaded up.

                Sselphs scraper

                essentially same process as before with images:

                cd /home/pi/RetroPie/roms/nes
                /opt/retropie/supplementary/scraper/scraper -video_dir=videos -video_path=videos -video_suffix="" -add_not_found=true -download_images=false

                  @herb_fargus I will have a chance to dive into it from Jun-14 on. I hope you don't lose momentum until then. :-)
                  I'm sure we'll get it working!

                    sounds good. I just have to figure out the emulators.cfg, then it should hopefully be functional, then we can focus on optimisations. I don't imagine this will be something for the average user though

                      Well I'm a noob. My method of going about this is all wrong and incredibly overengineered. I'm going to give it a break for a bit so fresh eyes can look at it.

                      I'm thinking the correct way to go about it would be to have a launch perameter in runcommand like we do for netplay or verbose logging except have it be for running a core with recording enabled.

                      I imagine that once Raspbian updates to stretch with ffmpeg in the repository, this could be something included in retropie by default and much of my script would then be redundant (hopefully!)

                      I was able to get sselphs scraper to scrape the videos correctly, but now the trouble is encoding it with a compatible codec that will play in emulationstation. Baby steps!

                              Since the recording is not an official feature, I think it wouldn't be a good way to go. But I've got an idea: what about a runcommand-onmenu.sh?

                              A script to be launched only if user invoke runcommand menu and choose the option to launch it. I'll try to submit a PR and let you guys review the code. I can think other use cases for such feature...

                                @meleu it may not be official now but if/when we update to stretch and ffmpeg is in the repos rather than requiring a source install then yes it may actually be viable to include by default but in the interim yes onmenu is a good solution (which I was unaware of) I await your solution

                                    @meleu how would the on menu be any different than onstart unless there is some mechanism for modifying the dialog menu for runcommand?

                                    Or are you saying it's an option in the runcommand menu to run a script?

                                        @meleu Necropost AHOY!

                                        • With the advent of raspbian stretch and subsequently ffmpeg integrated in the repos

                                        • the runcommand onmenu functions integrated

                                        • and Retroarch compiled with ffmpeg support:

                                        I think I'm ready to give this another go. The integration is all pretty much handled as far as no more need for source compilations, now the trick is just configuring the onstart/onmenu scripts and optimal settings for ffmpeg to capture native res gameplay without degrading performance.

                                        Runcommand OnMenu Options

                                        As far as onstart/omenu scripts go, a few options:

                                        • OnMenu that just launches the default config to the default video path with the saved video file being named after the rom.
                                        • OnMenu that creates a videos folder for the system being launched, uses the default config, and saves the video in the created videos folder named after the rom.
                                        • OnMenu with dialog options to select the saved video path and video config/container (mkv, mp4 etc), and maybe options to name based on rom, date, rom+date, etc.

                                        Runcommand OnMenu

                                        Per the docs, create a script called recordvideo.sh in `

                                        opt/retropie/configs/all/runcommand-menu/`
                                        

                                        With the contents todo incomplete!

                                        recordvideos.sh

                                        #!/usr/bin/env bash
                                        
                                        system="$1"
                                        emulator="$2"
                                        rompath="$3"
                                        launch="$4"
                                        rom_file="${rompath##*/}"
                                        rom="${rom_file%.*}"
                                        mediadir="$HOME/RetroPie/roms/$system/images"
                                        videofile="$mediadir/$rom-video.mkv"
                                        
                                        
                                        # Create videos folder in system's rom folder
                                        if [[ ! -d "$mediadir" ]]; then
                                            mkdir -p "$mediadir"
                                            dialog --msgbox "$mediadir created!" 20 60 >/dev/tty
                                        fi
                                        
                                        # Launch to record gameplay on RetroArch Systems.
                                        if [[ "$launch" =~ retroarch ]]; then
                                        eval "$launch" "--record '$videofile'" 
                                        exit 1
                                            else
                                            dialog --msgbox "Video recording is not supported for this system" 20 60 >/dev/tty
                                        fi
                                        

                                        if you want to force ~30 second limits for your videos you can substitute the following code:

                                        eval "$launch" "--record '$videofile'" & sleep 33
                                        killall retroarch
                                        exit 1
                                        

                                        Configs

                                        The default path for recorded videos is:

                                        /opt/retropie/configs/all/retroarch/records/
                                        

                                        If you add a custom config for ffmpeg the default path is:

                                        /opt/retropie/configs/all/retroarch/records_config/
                                        

                                        Examples:

                                        default.cfg:

                                          Hello @herb_fargus, I'm thinking about streaming my Retropie's screen to my Kubuntu desktop PC that's connected to my video projector, so that an audience of guests could watch the games. Can you kindly give me some hints how to set that up?
