How to resolve the video record issue?

[leon]

All,

I am focusing on the video record . Now the record case is working
normally. But the performance is too bad. Could you help me on this?

Step1, In camerahardwarestub.cpp we create a recordthread to get
data from sensor and display this data to LCD
Step2, By using the callback to send the data to
android_camera_input.cpp
Step3, The opencore will handle this data to encode and write the
encoded data to file

The video's resolution is 320x240.
Before starting the recording , the display will take 25ms to LCD.
After starting the recording, the display will take 55ms to LCD.

Whether is it related to the priority of these threads? Or
others?
Could you give some solutions?

Thanks a lot!

This question (which appears to be specific to the device you're
working with) would get better answers in android-porting, where
people are more familiar with the process to port Android to different
kinds of hardware.

Thanks,
