我完成了所有配置并在多个Android设备上进行了测试，一切正常，但是当我使用Vuzix M300测试流媒体时，这是在Android 6上运行的智能玻璃，流媒体并没有发生甚至没有在Android Studio中收到任何错误。请帮助我，我是Vuzix m300的新手。

答案 0 :(得分：1)
您可以尝试将粗体数字参数调低一点。
PeerConnectionParameters params = new PeerConnectionParameters(
true, false, displaySize.x, displaySize.y, **30**, 1, VIDEO_CODEC_VP9, true, 1, AUDIO_CODEC_OPUS, true);
至少，这有助于我们的案例..希望也能帮到你。
