Thank you for your help Clemens. Now, I understand a part of my problem. According to the constraints values, I totaly agree with you. But i miss something about the count parameter. Why the count parameter is not equal to the size of the period in the runtime pointer (i.e. in my example above: 8192) in the copy operator? I tried with new parameter: .period_bytes_min = 16*1024, .period_bytes_max = 64*1024, .periods_min = 2, .periods_max = 4, and the result were: runtime->period_size: 16*1024 runtime->periods: 4 I agree that values fit into constraints but the count parameter is always 1024. I don't understand why count is 1024 ? why count is not equal to runtime->period_size (i.e. 16*1024)? I'm shure i miss something. Maybe you can help me. I thank you very much for your help. regards, Mathieu ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
