iMX53 Android playback video on VGA WSXGA+ (1680x1050)

Hi,

I met a video problem.

Environment:

custom board base on imx53 QSB

Android system base on Adeneo 4.3 BSP

VGA WSXGA (1680x1050)

MX Player

When I playback video in HW mode, the screen is black or abnormal video.

It works on SW mode but lag.

I don't see any known issue or patch file on release note.

Had anyone ever met this problem?

Thanks!

Hello,Dean,

      Due to hardware limitation, you only use up to 1440x900 resolution(VGA-WXGA) on VGA interface. I have tested it . Main reason is clock issue.

      Even under VGA-WXGA mode, playing video is not continuous,too. GUI displaying and other operations are all OK.

      Only using 1024x768 on VGA port, playing video ,GUI display etc are all no problem.

      So when customer wants to use high resolution , the best way is to use DISP0 port.

Regards,

Weidong

Hi Weidong,

     Thanks for your answer quickly:)

     Did you have detail information about this clock issue (which clock).

     Does any document note this limitation?

     Why does this problem not occur on ubuntu?

Hello,Dean,

      I tested serveral resolution 1280x1024 and 1650x1080 on ubuntu platform, even GUI can display. But if you observe font, they become deformed. that's to say, Font is abnormal.

      I have disscused hardware issue on VGA with HW R&D, and confirmed it , but no documnet released .

Regards,

Weidong
