[mitchross]

can you share a sample git repo?

[ArjunNagraj]

Sure will create an app with the dependencies and share git repo to it. Thanks a lot :)

[ArjunNagraj]

Hi @mitchross please find the link to a sample git repo

[solid-yuriiprykhodko]

Hey! I think I've encountered a similar error before. It's caused by two packages depending on a single lib binary.
This isn't something that we can resolve at package level.

You'll need to add the following lines to your application's build.gradle:

android {
    packagingOptions {
        pickFirst 'lib/x86/libc++_shared.so'
        pickFirst 'lib/x86_64/libc++_shared.so'
        pickFirst 'lib/armeabi-v7a/libc++_shared.so'
        pickFirst 'lib/arm64-v8a/libc++_shared.so'
    }
}

@solid-yuriiprykhodko thanks though I am sure this will work I am only cautious of the effects it may cause at runtime and not knowing which the other plugin may be is difficult to plan a regression test.
Please let me know if by any chance u can tell what loads this library while using the VLC plugin,

[solid-yuriiprykhodko]

This plugin doesn't load libc++_shared directly. It's coming from the libvlc, which in its turn loads the lib as part of Android NDK version >=13.

It appears the VLC team uses the exact same approach for the Android VLC app:
https://code.videolan.org/videolan/vlc-android/-/blob/master/application/app/build.gradle#L20

[ArjunNagraj]

@solid-yuriiprykhodko
After adding these options thr build succeeds but there is a runtime error crashing the app.
packagingOptions {
pickFirst 'lib/x86/libc++_shared.so'
pickFirst 'lib/x86_64/libc++_shared.so'
pickFirst 'lib/armeabi-v7a/libc++_shared.so'
pickFirst 'lib/arm64-v8a/libc++_shared.so'
}

Run time error

[solid-yuriiprykhodko]

I can't seem to reproduce the error with the crash - the video surface fails to load, but I'm still getting the audio.
Could you please update the sample app you've shared to reliably reproduce the crash?

[ArjunNagraj]

@solid-yuriiprykhodko have pushed the latest code....can u please check it now....The device i am running the debug with his a
Redmi Note Android : 8.1

[solid-yuriiprykhodko]

Checked out the example - can't repro the crash, but the live video doesn't play for me.
Device: Huawei P40
Android: 10.1

It seems to be a mediacodec issue:

[ArjunNagraj]

@solid-yuriiprykhodko thanks a lot for checking....i do not know why its crashing in my build. Will it help if i can share the debug apk from my build.
The RTMP stream failed to load as the live stream was not active.

[solid-yuriiprykhodko]

@ArjunNagraj Let's try the APK -- might be a problem with build tools version.

[ArjunNagraj]

@solid-yuriiprykhodko Please find appended below the link to download the file.

Thanks a load 🙏.

[ArjunNagraj]

@solid-yuriiprykhodko please let me know if you were able to download the APK.

[solid-yuriiprykhodko]

@solid-yuriiprykhodko please let me know if you were able to download the APK.

Hi! Just tried out your APKs - crash does get reproduced.
You didn't mention that the problem appeared on release builds - when I tried doing a release build locally, it crashed for me, too.

My guess is that this happens due to code shrinking - we'll need to experiment with ProGuard rules to make sure any necessary libs don't get excluded.
