hmm. That's going to be tricky.
Could you remove RTMP protocol dependency there:

StreamPack/demos/camera/build.gradle

Line 54 in 908f7f0

implementation project(':extension-rtmp')
? You will have to remove RTMP classes as well.
It is just for a test.
Do you need both RTMP and SRT?
RTMP and SRT are both shipped with a version of libssl/libcrypto and I suspect that gradle picked one that is missing API.

Thanks for the reply.

I'm just doing some exploration at the moment so I'm not sure if I'll be using RTMP or SRT, I think either is suitable.

I've tried removing the RTMP dependency, and I find it still has the same error.

If I put back the RTMP dependency and remove the SRT dependency I get another error, which looks similar, but is from librtmp this time:

I don't have a clue why this is happening 🤔
Might be because you are using a custom phone and something is missing in the implementation.

I made a test where I enforce loadLibrary of ssl and crypto: https://github.com/ThibaultBee/StreamPack/tree/test/openssl
Could you test it?
Hopefully it will be called before loading rtmpdroid and srtdroid.

For RTMP, you could try something like that the dependencies:

  implementation("video.api:rtmpdroid:1.2.1-packed")
  implementation project(':extension-rtmp') {
    exclude group: 'video.api', module: 'rtmpdroid'
    // exclude the transitive dependency to use packed version to avoid conflict with libssl.so and libcrypto.so
  }

I've tried the test/openssl branch you created, and that fixes the problem for me, thank you!

I suspect you are correct that it is something missing on the device, and it's not a general issue. It's currently beyond my understanding, but if I work out what is happening I'll let you know.

Ok, I will add this is in native dependencies (srtdroid and rtmpdroid):

    System.loadLibrary("crypto")
    System.loadLibrary("ssl")

Already in rtmpdroid: apivideo/api.video-rtmpdroid@d7eb771

But it will take a while.

Ok, I will add this is in native dependencies (srtdroid and rtmpdroid):

    System.loadLibrary("crypto")
    System.loadLibrary("ssl")

Already in rtmpdroid: apivideo/api.video-rtmpdroid@d7eb771

But it will take a while.

Unfortunately, I can't do something like this. In few projects.,I use srtdroid and rtmpdroid as fat lib (all packed in one single lib instead of several libraries), and this will make the usage of fat lib impossible.

Moreover, the bug is within few devices that can't link libraries.

But a workaround could be to used these fat libs (but your APK is going to be bigger).
As an example, see https://github.com/apivideo/api.video-reactnative-live-stream/blob/731de483bdd8b955211bf39daa904dca692e16dd/android/build.gradle#L123

implementation("video.api:rtmpdroid:1.2.1-packed")
implementation("video.api:android-live-stream:1.4.2") {
  exclude group: 'video.api', module: 'rtmpdroid'
  // exclude the transitive dependency to use packed version to avoid conflict with libssl.so and libcrypto.so
}

A solution might be to use ReLinker
But it does not seem update anymore.
