Open-source source code
Pagiro for Android plays slide-show sounds and videos in older formats (WMV, WMA, ASF, AVI, MPEG) with an open-source media library, libmpv.so. Parts of it are licensed under the GNU Lesser General Public License (LGPL). Here is its complete source code, and how to rebuild it and put your own build into the app.

For Pagiro 1.0.0 for Android:

b272dbb5a29a6476039d73f0871bc3b3db7755253dc866cb3edda10fae6d506b): the LGPL source. It holds the exact upstream source archives of mpv, FFmpeg and FriBidi at the versions used, with SHA-256 checksums of every component; our only change to them (a small patch to mpv that hands Android’s Java VM to FFmpeg); the build script with all its configure options; a README on how to rebuildlibmpv.soand replace it in the app; and the license texts.
The library also links in libass, FreeType and HarfBuzz, which are under permissive licenses. Their exact sources are the projects’ own release archives:
- libass 0.17.1 (SHA-256

427201f5d5151670d05c1f5b45bef5dda1f2e7dd971ef54f0feaaa7ffd2ab90c) - HarfBuzz 8.3.0 (SHA-256

Each app version that ships a different build of the library gets its own archive here, and every archive stays available for at least three years.

Replacing the library
The app loads libmpv.so as a separate shared library (in lib/arm64-v8a/ of the app package) through mpv’s client API, so a modified build with the same interface can take its place:
- Rebuild
libmpv.sofrom the archive (its README has the steps; the script runs on Ubuntu 22.04). - Copy the app’s APK files from your device, replace
lib/arm64-v8a/libmpv.so, align the APK (zipalign -P 16 -f 4) and sign the set with your own key (apksigner). - Install the set on your device (
adb install-multiple).
A copy signed with your key cannot receive updates or purchases from Google Play; everything else keeps working. Our terms allow you to modify these libraries and to reverse engineer the app to debug such changes.
Written offer
If you cannot download the archive, write to contact@tdhsoft.com. For at least three years after we last distribute a version of Pagiro for Android, we will send anyone who has that version the complete corresponding source code of these libraries, for no more than our cost of providing it.
