你懂不懂什么叫hdcp？鬼知道你自己哪个设备不支持
"Yes, modern versions of Chrome generally support HDCP, but it is often the overall playback system (including drivers, operating system, and display connections) that determines if HDCP protection works correctly. If you are experiencing an HDCP error, the issue is likely with your hardware or connections, not with Chrome itself. "
"A chain must be HDCP-compliant: For a video to play in HD, every device in the playback chain—from the computer's graphics card, to the operating system, to the display connection (like HDMI or DisplayPort), and finally to the TV or monitor—must be HDCP-compliant. "
