Hi, Currently when playing stream from memory through dvr device (through write calls), the written buffer is copied from user-space to kernel space. The same applies when recording a stream, the TS packets received from HW are copied to dvr ring-buffer.
I'm a bit concerned about the performance due to the copy, and whether we better have a memory mapped ring-buffer in dvr device output and/or dvr device input with user-space to cope with high bitrate streams. Your feedback on this will be mostly appreciated.
