Building

Get your preferred version of FFmpeg from https://github.com/arthenica/ffmpeg-kit/releases or https://gitea.antonlyap.pp.ua/antonlyap/ffmpeg-kit/releases (includes updated FFmpeg and resolution alignment patch).
Place the AAR file under app/libs
Build the APK:
```
./gradlew assembleRelease
```

Extract the APK:

unzip app/app/build/outputs/apk/release/app-release-unsigned.apk

Create an archive with the following files (ffmpeg and ffprobe can be found under cmd/):
```
lib/
classes.dex
ffmpeg
ffprobe
```

Useful software and resources

MediaCodecInfo - displays the capabilities of your device.
rclone - lets you mount a remote filesystem (e.g. to transcode files from your computer). Requires root access and the fusermount3 binary. Some media containers require --vfs-cache-mode=writes to function properly.
FFmpeg Streaming - also lets you access remote files.
rffmpeg - lets you control transcoding from another machine over SSH.
