Start with org.webrtc.EglBase14Impl.createEglContext and the callers shown in the trace, especially EglRenderer.init and CallActivity.initSelfVideoView during picture-in-picture changes. Investigate the reported Android GLException using the supplied stack trace; done means the failure is reproducible and its affected device or configuration and resolution are identified.
