Problem with video display for 1080p & 720p.

Hi all,

On our custom hardware board using TI8148, a HDMI received is connected to VIN[0] port A and video is input in RGB24bits.

I'm using saLoopBackFbdev to capture the video and display the video on the attached LCD.

I'm able to capture and display the video with correct color for 720x480p video stream.

Things are working fine for 720x480p video stream.

However, if the video stream is in 1080p or 720p, the captured video displayed on the LCD have the incorrect color and there's a blank vertical bar on the right side as shown in the picture attached. (The picture is captured for 1280x720p video stream).

Using the saLoopBackFbdev, the mode for display1 is set accordingly to "1080p-60" and "720p-60" depending on the video stream detected.

I dumped out one video frame and confirmed that the captured video frame in the frame buffer has the correct color. 

I'm using TI EZSDK 5.05.01.04 with HDVPSS_01_00_01_37 with 5633.v4l2 patch.

Please advise.

Thank you.

Regards

May
