I am modifying my ivtv settings to increase buffer size. I am using the
following string;
options ivtv enc_yuv_buffers=8 enc_mpg_buffers=48 enc_vbi_buffers=16
enc_pcm_buffers=960
So by my math 8MB YUV + 48M MPG + 16M VBI + 960k = ~73M per tuner.
I have four tuners...
After boot I;
sudo rmmod ivtv
My memory usage is at 435672k used. After I;
sudo modprobe ivtv
My memory usage is 1029156k used, for a difference of 593484k or ~148M per
card.
As far as the modino states the defaults should be So by my math 2MB YUV +
4M MPG + 1M VBI + 320k = ~7M per tuner.
With no modifier string my memory usage is 16M per card.
Any idea why my memory usage would be approximately double the assigned
buffer size?
