Is there any reason for frame drops in IPIPE ?

Hi All,

I am trying to capture a video 1080p@30fps in OMAP5 ISP platform, But facing some frame drops in IPIPE. If anybody know the issue please give me some hits to fix this.

Issue in details for better understanding.....

  • I am able to get 1080p@30fps for raw and yuv(from sensor) data without IPIPE in the pipeline. i.e Image pipeline is "SENSOR->CSI2->VP->IPIPEIF->ISIF->IPIPEIF->RSZ->BL->SDRAM"
  • But If I add IPIPE in above path then it is working at 1080p@15fps.                                                      "SENSOR->CSI2->VP->IPIPEIF->ISIF->IPIPEIF->IPIPE->RSZ->BL->SDRAM"

Thanks in advance!!!

    Hi,

    Which OS do you use on your omap5 board (Android or GLSDK release)?

    In general there is no reason for the lower frame rate, when adding IPIPE to your data path. Both 30fps & 15fps are typical for preview, can you check is there any condition that changes the frame rate in your sensor driver?

    Best Regards,
