based on what you're saying, i believe you mean not so much the dvr buffer, which can be changed from application side, but more the buffer used for data transfer from the side of the driver - that depends not just on the driver, but as well on the usb-endpoint settings. anyway, i believe i get your point and i'm going to investigate in such direction, i.e. if it's possible with changing buffer size to improve the usb performance. i will keep you inform here - expect in few days to be able to tell you more.
Yes, sure. I'm trying to find a chipset limit for create any calculator, how much bitrate can be used for both adapter.
You know, all devices into MOI are connected via USB (8). In next revision I'm recommending awesome dedicated network chip as first step...
I don't think, that with changing of dvr buffer we can improve the usb performance (will be as is), but we can eliminate empty dvr read state (EOVERFLOW) and will see, where is limit of chipset.
This method isn't secure on some boards.
With enlarge of default size of dvr buffer, be careful with testing of TPs. In the moment, You will have a crc errors in stream, or lost packets, You need to stop testing.
And send stream only to dvr, without network using (Have limit about 50M).
Thanks.
