library "libmpv.so" not found

[Osanosa]

erm 🤓☝️ i think you have gitignore misconfigured, apk i built has no mpv

also
implementation(files("libs/ext.aar")) /* ExoPlayer's FFmpeg extension */

[Osanosa]

oh okay ext.aar is there
tho i still get

[Osanosa]

or is mpv built via actions? i'm genuinely confused

[Osanosa]

libavcodec.so
libavfilter.so
etc

there's no jniLibs folder
I don't get it

[Osanosa]

I don't get it
why would you remove it
how do you expect anyone to contribute?

[yuroyami]

@Osanosa Sorry for the confusion. The .gitignore is not misconfigured—I deliberately excluded the .so files since they can be obtained elsewhere. The jniLibs folder (which should contain libmpv's library files for the four common ABIs) is only weakly referenced through this symlink.

My original plan was to use the mpv-android build scripts to generate the library files, but I ran into some issues setting them up. As a temporary workaround, I'm currently extracting the libs directly from mpv-android's APK and placing them in a jniLibs folder under androidApp/src/main/, with the four ABI-specific folders inside. This should allow the build to proceed successfully.

This isn’t what I want everyone to go through, and I know I haven’t explained it elsewhere. But I believe everything will be clearer once I start leveraging the build scripts to generate libmpv instead of taking it already baked and cooked from mpv-android's APK files.

If you have any other questions, let me know.

[Osanosa]

Can you please share a screenshot of what files are there so I could manually extract them from latest release?

[Osanosa]

And maybe you have a telegram group or elsewhere where I could discuss development and contributions if needed

[yuroyami]

@Osanosa After extracting the APK, you will find a folder called "lib", under which you will find 4 folders (each for a specific ABI), I copy those into the jniLibs folder (which you need to create under androidApp/src/main) so that the hierarchy becomes like this:

androidApp
- src
- - main
   - - jniLibs
      -- arm64-v8a
      -- armeabi-v7a
      -- x86
      -- x86_64

One more thing to note: Since libc++_shared.so doesn't have anything to do with libmpv, you can delete it from every ABI folder.

And maybe you have a telegram group or elsewhere where I could discuss development and contributions if needed

Not at the moment—I hardly have any time to continue development on this project. However, it’d be great if you could start a thread in this repo’s discussions if you want to talk about anything.

[Osanosa]

Thanks, I've already copied them over
I was worried there would be resolution conflicts.

Expect some pull requests soon!

[Osanosa]

tho can you send a list of what libs you have in that folder?
coz some override dependencies and are used from module

[yuroyami]

@Osanosa

All files except libc++_shared.so
