Subject: [media][dvb-core] Question on dvr device copy
Hi,
Currently when playing stream from memory through dvr device (through write
calls)
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
