download.sh will take care of installing the Android SDK, NDK and downloading the sources.
If you're running on Debian/Ubuntu or RHEL/Fedora it will also install the necessary dependencies for you.
./download.sh
./buildall.sh
Run buildall.sh with --clean to clean the build directories before building.
Building for just 32-bit ARM (which is the default) is fine generally. However if you want to make use of AArch64 or are targeting Intel x86 devices, these architectures can be optionally be built into the same APK.
To do this run one (or both) of these commands before ./buildall.sh:
./buildall.sh --arch arm64 mpv
./buildall.sh --arch x86_64 mpv
adb logcat # get all logs, useful when drivers/vendor libs output to logcat
adb logcat -s "mpv" # get only mpv logs
If you've made changes to a single component (e.g. ffmpeg or mpv) and want a new build you can of course just run ./buildall.sh but it's also possible to just build a single component like this:
./buildall.sh --no-deps ffmpeg
# optional: add --clean to build from a clean state
Note that you might need to be rebuild for other architectures (--arch) too depending on your device.
Afterwards, build mpv-android and install the apk:
./buildall.sh --no-deps
adb install -r ../app/build/outputs/apk/debug/app-debug.apk
You can use Android Studio to develop the Java part of the codebase. Before using it, make sure to build the project at least once by following the steps in the Build section.
You should point Android Studio to existing SDK installation at mpv-android/buildscripts/sdk/android-sdk-linux. Then click "Open an existing Android Studio project" and select mpv-android.
If Android Studio complains about project sync failing (Error:Exception thrown while executing model rule: NdkComponentModelPlugin.Rules#createNativeBuildModel), go to "File -> Project Structure -> SDK Location" and set "Android NDK Location" to mpv-android/buildscripts/sdk/android-ndk-rVERSION.
Note that if you build from Android Studio only the Java part will be built. If you make any changes to libraries (ffmpeg, mpv, ...) or mpv-android native code (app/src/main/jni/*), first rebuild native code with:
./buildall.sh --no-deps mpv-android
then build the project from Android Studio.
Also, debugging native code does not work from within the studio at the moment, you will have to use gdb for that.
You first need to rebuild mpv-android with gdbserver support:
NDK_DEBUG=1 ./buildall.sh --no-deps
adb install -r ../app/build/outputs/apk/debug/app-debug.apk
After that, ndk-gdb can be used to debug the app:
cd mpv-android/app/src/main/
../../../buildscripts/sdk/android-ndk-r*/ndk-gdb --launch
Travis will create prebuilt prefixes whenever needed, see build_prefix() in .travis.sh.
These prefixes contain everything except mpv built for armv7l and are uploaded here.
These build scripts were created by @sfan5, thanks!
