Record RetroArch gameplay on Android with a reproducible test
First confirm that your exact Android package exposes a Record driver and recording controls. Set a writable recording directory, load one authorized game, record a ten-second baseline at default settings, stop cleanly, and play the file outside RetroArch. If no recording control or file appears, treat that as a package, encoder, or storage boundary rather than inventing a path or codec.
Do this in order
- 01
Record the RetroArch package source, version, Android version, free space, active core, and one authorized game's identity.
- 02
Open Settings > Drivers and the recording settings; stop if the package exposes no Record driver or recording action.
- 03
Choose a writable recording directory shown by RetroArch; do not type a guessed private filesystem path.
- 04
Load the authorized test game, keep shaders and latency extras off, start recording, play for ten seconds, then stop recording before closing content.
- 05
Open the resulting file in another local player and record container, duration, video, audio, size, and output location.
- 06
Only after the baseline passes, change one quality or encoding setting and repeat the same scene; keep the working configuration receipt.
Decision and diagnostic table
| Observation | Boundary | Next action |
|---|---|---|
| No Record driver or action | Package build | Use an official build that declares the feature |
| Starts but creates no file | Output path or encoder | Check the notification and verbose log |
| Video works, audio missing | Core audio or encoder | Test default audio and inspect the log |
| Clip stutters | Device headroom | Remove shaders and compare without recording |
Recording is a build capability
Libretro documents recording through FFmpeg, but an Android package may omit the required support. A menu name is not proof that a particular codec or container is available.
The first clip is a control experiment
A short default clip separates storage and encoder availability from expensive shaders, run-ahead, high resolution, or long-session heat. Playback in another app proves that a usable file was finalized.
Keep performance claims measured
Compare the same scene with and without recording and note emulation speed, dropped frames, audio, temperature warning, and file growth. Do not claim a device or codec was tested unless that receipt exists.
Use only game, firmware, artwork, music, and media files you created, dumped lawfully, or received under permission covering your use. Emulator compatibility never grants content rights; do not use unauthorized ROM, BIOS, CHD, artwork, music, or download mirrors.
