Hi This is just a general question to understand where the improvement can be made.
In the first setup, I have these processes: - mencoder recording from bttv chip at 8 fps (cpu 3.5 %) - mplayer playing from bttv chip at 10 fps (cpu 2.1 %) In the second setup, I have these processes: - mencoder recording from bttv to shared mem at 25 fps (cpu 1.7%) - mencoder recording from shared mem at 8 fps (cpu 6.1%) - mplayer playing from shared mem at 10 fps (cpu 3.1 %) For the shared mem setup, the access to the memory is efficient, only a memcopy to a buffer. Are the CPU usages inline with what you'd expect, that the shared mem being almost 2 times the CPU usage? How can I reduce the CPU usage in the shared mem setup?
