Facing the problem regarding Frames on the Screen using Ezsdk 5 05 02.

Hello,

What you are using gstreamer?
In EZSDK we have saLoopBackfbdev demo:
processors.wiki.ti.com/.../TI81XX_PSP_VIDEO_CAPTURE_Driver_User_Guide
Which capture frames and display them by FBDEV driver.

Thanks Margarita for reply,

I am displaying frames from a udp camera , using a socket programing for capturing frames,
My app is running fine for a while , but after some time it stucks , or I see the blakc screen , and when i am trying to escape the app by pressing ctrl+c it says VPSS_FVID2: contrl event 0x6 timeout. >ti81xxfb

Sometimes it gives this error , after some time .
