i.MX6 Wifi-Display function

[adamwen]

Hi,

I am testing the WiFi-Display function (Miracast) in i.MX6Q Sabre SDP
board, but cannot connect successfully. I have tried two different Miracast sink devices,
and the result is same

I can see the connection is stopped in RTSP connection stage from the TV
screen. And the log msg is below. From the log info, we can see the hdcp and
codec error. So can anyone help us to analyze the problem? Or this
function is not fulfilled in this release version BSP.

The Android BSP version is android_jb4.2.2_1.0.0-ga.

The log message is as below: (error in red)

Thank you for your reminding.

Hi Adam

what sink devices you used and whether you know anything about having miracast device directly on the SoC?

[adamwen]

I bought one Sink device something like HDMI dongle from the market, but sorry I don't know much about the SoC. I think there is no much special requirement for the SoC, the Miracast is mainly a software protocol.

[lily_zhang]

From your shared log, it seems your WiFi sink device is HDCP enabled.

android_jb4.2.2_1.0.0-ga doesn't support HDCP. So please double check whether your WiFi sink device is HDCP enabled.

[adamwen]

Thank you for your help, recently I downloaded the latest BSP android_jb4.2.2_1.1.0-ga, and this isse is solved.
