@kingfrankbob Your last post doesn't seem to fit to this topic. Wrong thread?

You can record both the Rpi audio-out and HDMI-video in webm format from within the PC/Android browser (plugin-free) with UV4L (no need of any capture card). This is a demo showing hot to play a game in the browser: You do not see a record button in the above page because it is used to only play the game, but there is another page available at a different url on the same uv4l web server with the record functionality. You can even record from within android chrome:

@mitu ok then

@geneworld not via emulators.cfg - you would need to modify runcommand and add support for some custom %DATE% token.

This is a post on screen casting: https://retropie.org.uk/forum/topic/17459/retropie-screen-mirroring-streaming-casting This is the latest on recording gameplay with ffmpeg. It will more than likely be laggy. https://retropie.org.uk/forum/post/133352

I did a bit of testing here: https://retropie.org.uk/forum/post/133352

it works! I just want to say this works now. I can finally record how I play on this thing, which just refused to work before. I installed the newest firmware and tried it again. But since April (we have December now) a lot of things changed since then. If the above posting is a bit confusing, here is a brief explanation. I just have to switch a single HDMI output to be able to record. The PVR Rocket is a portable device to record from any HDMI source up to 1080p30 or 720p60 to a usb drive. I usually use my RetroPie system with my old crt pc monitor at 640x480p. It is connected with a HDMI to VGA converter and all boot and emulator settings are optimized for that. The recordings are saved at 640x480p at 60 fps. Recording: The HDMI output from Raspberry Pi is connected to the input at PVR Rocket. Then the PVR Rocket have also an 0 delay pass through HDMI output, which is connected to my final monitor. A single button press starts the recording and a second press stops it whenever I want. Playing without recording: The HDMI output from Raspberry Pi is connected to a VGA splitter. That VGA output is connected to my final crt pc monitor. To get sound, the VGA splitter will output 3,5mm audio jack.

One way you could do it is to get an Capture Card (like an Elgato) and then Record it from your PC Screen.

Or is there a possibility to host a Game on a Windows computer or Mac and others can join? So i could just record my windows/mac screen to record the gamplay...? I tried to host a hgame with Project64 and the AQZ-Netplay Plugin but my retropi said: "implementations differs", when i tried to join the game with my retropie :/

Sorry to bump this, but does anyone know how to pass additional commandline options to ffmpeg via --recordconfig?

@herb_fargus to avoid this confusion I've just made a PR to explicitly use rgui as the menu_driver. https://github.com/RetroPie/RetroPie-Setup/pull/1674

Hey anyone get this working on RetroPie 4.4 RetroArch v1.7.1 Raspbian Stretch?

Just an update in case anybody was watching this (the original) post - I've finally published the guide... I hope that you find it helpful - please feel free to ask me any questions (as I've not had time to polish it quite as much as I'd like) Details are on the forum post here: https://retropie.org.uk/forum/topic/2394/how-to-guide-recording-live-gameplay-in-retropie-s-retroarch-emulators-natively-on-the-raspberry-pi-and-twitch-streaming A direct link to the guide is here: Recording Live Gameplay in RetroPie’s RetroArch Emulators Natively on the Raspberry Pi
