TDA4VM: How to tuning the image capture performance, along with two h264 encoder working as the same time?

Hello, 

I am not sure about what your implementation is. Could you give more details about your environment? How are you implementing the encoder, is it with our Linux or QNX driver?

Thanks,
Sarabesh S.

Hi, thanks for you reply. The encoder implement with V4L2, which is provided by SDK I think. I'm not good at such field, only know that it can work. 

The following key interfaces are used for the encoder:

Hello,

Ok thanks for the information. I assume you are using a custom application that is demoing the encoder using v4l2-based functions in the Vision Apps SDK. 

Are you writing the output to display or is it being written to a file? Is the input coming from a camera?

Thanks,
Sarabesh S.

Yes, the application input is from camera, and output by sending the encode data to PC client by TCP protocal.

According to our comparing, if the encoder is not work, the application capture fps is 25 fps, when encoder works(sending at the same time), fps is about 22 fps.

Hello, 

I am out of office, please expect a delay in response. 

Thanks,
