Im getting the following error.

Fatal Exception: java.lang.UnsatisfiedLinkError: No implementation found for boolean org.webrtc.LibaomAv1Encoder.nativeIsSupported() (tried Java_org_webrtc_LibaomAv1Encoder_nativeIsSupported and Java_org_webrtc_LibaomAv1Encoder_nativeIsSupported__) at org.webrtc.LibaomAv1Encoder.nativeIsSupported(LibaomAv1Encoder.java)

It seems that HW does not support AV1 encoder?

davidzhao commented 2 years ago

most devices don't support hardware av1. I think @davidliu's fallback handling should have resolved this.

davidliu commented 2 years ago

I think there's an issue with the JNI linking code here, seems to be broken somewhere. If the software video encoder fallback handling is relied on to create these codecs, it'll crash due to the linking issue.

Oh, this is actually an old android bug with loading native libraries with an app that has a minimum sdk less than 21.

The solution is to use the https://github.com/KeepSafe/ReLinker library to load native libraries. This will fix any issues with UnsatisfiedLinkErrors.

Closing since it's an issue with Android rather than the webrtc library.

One other possibility that came to mind is that you're trying to access the native library before it's loaded into memory. PeerConnectionFactory.initialize() loads the native library, but if you try to use any native methods prior to loading, it will crash.
