Thanks - this is useful for headless pi-ers - like me!
240 MB of RAM is "as much as anybody would need"
I have just discovered this new possibility
From 220 MB ('total' showed by 'free' command) now I have 236 MB
One more thing. I am using USB webcams with rpi (accesing them via uvcvideo / v4l or v4l2).
Rpi is completly headless, I'm just producing tons of *.JPG files.
For capture I am using 'motion' or 'fswebcam' - generally I'm using programs that are based on v4l and /dev/videoX (/dev/video0, /dev/video1, ...).
Now I set 240/16 memory split but I started to have doubts if it will work stable for me...
How do you think: could GPU and it's RAM be involved into image capture and/or JPEG compression process??
(If yes, is 16MB RAM for GPU enough for headless rpi that creates JPEG files in 1920x1080 using MJPEG palette [sometimes it is also called 'input type'] ??)
