Decky Recorder

This plugin is heavily based on the Recapture-Plugin for Crankshaft from Avery: https://git.sr.ht/~avery/recapture In particular a lot of code for the gst-launch-1.0-command itself and the additionally needed dependencies were taken from the Recapture-Plugin.

This plugin was made with the decky-plugin-template (https://github.com/SteamDeckHomebrew/decky-plugin-template)

Please do not judge my code, I am bad!

This plugin is still in WIP.

Thanks

• Huge huge thanks to @safijari for fully implementing Rolling Recording/Replay Mode (https://github.com/safijari/decky-recorder/tree/rolling-record)
• @Newbytee for pointing out that I forgot the "-e"-option in the gst-launch-1.0-command
• Avery for the original Recapture Plugin
• Epictek for inspiring me to setup a proper build process (https://github.com/Epictek/DeckyStream I found out about this plugin when I was basically already done q.q)
• kleutzinger for fixing the file names and making it so it confirms with ISO_8601
• DerpyChap for adding a few audio related improvements (AAC and Stereo)

Known issues

• It seems like long recordings (over 30 minutes) dont get saved (marissa999#2 (comment))
• It seems like starting a recording while docked and outputting to a 4k monitor causes the Deck to crash (marissa999#8)

Building

If you want to build this plugin in theory you only need to run build-zip.sh. You will need the following:

• npm
• pnpm
• python + pip
• Docker
• zip I only tested this on Arch Linux (which I use, btw!)

TODO

• WIP: Adding the option to toggle game audio + mic audio (Current state: You can enable mic audio, but not disable game audio. Figure out a way to filter and remove audio from pipewiresrc?)
• WIP: Figuring out why sometimes recording stutter/audio + video don't align. Might require re-transcoding with ffmpeg to re-align dts-stuff? Dunno (Current state: FFmpeg will now copy the files from tmpfs to the ~/Videos-folder and fix dts while doing so. Not working: FFmpeg needs to run AFTER gst-launcher-1.0 finished, but because gst-launcher-1.0 is running through a python subprocess with shell=true this is apparently not that easy and I can not just wait for it?!)
• WIP: Finishing RTSP-Server-Sink (Current state: UI is done, I should have all libraries? I think? And if not I can easily add missing libraries. But... What is the actual pipeline that I need?)

FAQs

Can I save to the SD card / some other location?

This is not yet configurable through the plugin but yes. What you would do instead is

1. Move your Videos folder to the new destination (e.g. /run/media/mmcblk0p1)
2. Make a symbolic link (e.g. ln -s /run/media/mmcblk0p1 /home/deck/Videos)

Now it'll look like there's a Videos folder on your ssd but the data will actually be in the SD card.
