share screenshots and recrordings from RetroPie to twitter:

This was setup to run on a Raspberry Pi 3 Model B running RetroPie. I'm sure it would work on other Retroarch's as well. I wouldn't try this on an older Pi 1, or single core system. The screenshot stuff should work (maybe this should be configurable?) but the recording/gif converting would likely be too slow on a single core system (it can already bog down the Pi 3 at times).

What you really really need is:

(I am sure versions can flex a bit)

If you are setting these things up on RetroPie you can follow these guides:

• Recording Live Gameplay in RetroPie’s RetroArch Emulators Natively on the Raspberry Pi
• Recording gameplay videos on RetroPie (with some handy shell scripts!)
• I also ran into this snag

clone this repo somewhere:
git clone git@github.com:rickycodes/retrorecord.git

You'll need to modify values here to match your needs (the folder structure needs to be set up by you and depending on how you configure RetroArch the folders may vary)

this file also needs to be renamed to config.rs

build with cargo:
cargo build
or:
cargo build --release

run unit tests:
cargo test --verbose

run the binary:
./retrorecord
or:
./retrorecord ----prompt
(this will prompt you before posting)

run the binary:
./retrorecord
and you should see:

application started...
prompts are OFF

Get to a screen in game that you'd like to capture and enter the main menu of RetroArch:
Go into the "Quick Menu" and select "Take Screenshot":

retrorecord will print something like this to stdout:

file written: "/home/pi/.config/retroarch/screenshots/Super Mario Bros 3 (U) (PRG 1)-180425-190211.png"

Launch a game that has an emulator with an option where you've enabled recording: (Press a button to configure):
Select default emulator, or Select emulator for ROM:
Select the emulator where you've enabled recording:
Now simply launching the game will start recording:

Once you exit the game the recording will stop and you should seem some ffmpeg output from retrorecord followed by:

gif complete!
gif_path is "/home/pi/gifs/output.gif"
posted tweet!

If you want to record specific sections of a game consider using save states: play the game with the normal emulator to a point where you'd like to start recording, save state then relaunch with the recording enabled and load state to record from that point onward.

All this app really does is watch folders for screenshots & recordings, so presumably you could get this to work on most systems? While this was used to create whatmeplaying you could use a similar setup to post screenshots/videos/gifs from games to anywhere (so long as there's an API of some sort).

Most of the magic (literally ImageMagick) is in the mkvToGif.sh file
