Hi there, I guess the reason behind your request is: https://developer.android.com/guide/practices/page-sizes Ok, it is for native code, so it concerns the dependencies: srtdroid and rtmpdroid.

BTW, it won't be fixed in 2.6.1, probably in 3.1 because I don't have the access to rtmpdroid anymore.

Do you know where are the issues in the code?

[ThibaultBee]

Do you use RTMP or SRT?

[GreenVegetables]

I’m using SRT, and Google Play now requires all apps to support 16KB memory alignment. Otherwise, the app may be removed in the future. I tried to recompile the srtdroid source code myself, but I failed because I couldn’t find srt.h and other related C++ files. I’m currently using StreamPack and srtdroid, but neither of them supports 16KB alignment at the moment.

I know this is a bold request, but if possible, I sincerely hope you can update these libraries to support 16KB alignment.

[GreenVegetables]

This app can check whether other apps’ native libraries support 16KB alignment. I hope it’s helpful to you.

You can refer to this documentation to learn how to recompile native libraries with 16KB alignment support. I hope it’s useful to you.

[ThibaultBee]

I am working on srtdroid to fix this. But it is not that easy. I got to update the packaging to the new Maven Central portal + deal with OpenSSL. See https://github.com/openssl/openssl/issues/26913

I will be pushed in StreamPack 3.0.0-RC3.

Concerning RTMP, as I not longer have access to rtmpdroid, it will take more time. Also, I am working on another RTMP libraries for a while that will be integrate in 3.1.0.

[ThibaultBee]

Done on main branch for srt.

The work on RTMP is almost done. I am just waiting for this issue: https://youtrack.jetbrains.com/issue/KTOR-8642#focus=Comments-27-12303807.0-0

If you want to test the new RTMP provider (aka krtmp).

git clone [email protected]:ThibaultBee/krtmp.git
cd krtmp
./gradlew publishToMavenLocal

Then in a StreamPack clone, checkout feature/rtmp_provider branch.

I have tested on YouTube, Node Media Server and ffplay. I would appreciate some feedbacks on which RTMP server you have tested.
