Under R5A15.1 upgraded with a PVR-350, a PVR-500 and ivtv 0.3.4q using analog cable (no external cable/sat box, no IR emitters). CPU is Athlon64 3400+, hard drive has DMA on.
I'm getting about 6-9 seconds between tuner changes, as evidenced here (from syslog):
Code:
May 14 23:05:18 mythtv-backend-1 kernel: saa7115: decoder set picture bright=127 contrast=63 saturation=63 hue=0
May 14 23:05:18 mythtv-backend-1 last message repeated 3 times
May 14 23:05:18 mythtv-backend-1 kernel: saa7115: decoder set size
May 14 23:05:18 mythtv-backend-1 kernel: ivtv: Allocate DMA stream 0 using 128 16384 byte buffers 2097152 kbytes total
May 14 23:05:19 mythtv-backend-1 kernel: saa7115: decoder disable output
May 14 23:05:19 mythtv-backend-1 kernel: saa7115: decoder enable output
May 14 23:05:27 mythtv-backend-1 kernel: saa7115: decoder set picture bright=130 contrast=63 saturation=63 hue=0
May 14 23:05:27 mythtv-backend-1 kernel: saa7115: decoder set picture bright=127 contrast=63 saturation=63 hue=0
and here:
Code:
...
May 14 23:01:14 mythtv-backend-1 kernel: cx25840: decoder disable output
May 14 23:01:14 mythtv-backend-1 kernel: cx25840: decoder enable output
May 14 23:01:20 mythtv-backend-1 kernel: cx25840: decoder set picture bright=127 contrast=63 saturation=63 hue=0
May 14 23:01:21 mythtv-backend-1 last message repeated 3 times
And about 5 seconds or so between channels using the up and down keys on the keyboard:
Code:
May 15 00:08:20 mythtv-backend-1 kernel: cx25840: decoder disable output
May 15 00:08:20 mythtv-backend-1 kernel: cx25840: decoder enable output
May 15 00:08:21 mythtv-backend-1 kernel: ivtv: Allocate DMA stream 0 using 128 16384 byte buffers 2097152 kbytes total
May 15 00:08:21 mythtv-backend-1 kernel: cx25840: decoder disable output
May 15 00:08:21 mythtv-backend-1 kernel: cx25840: decoder enable output
May 15 00:08:26 mythtv-backend-1 kernel: cx25840: decoder set picture bright=127 contrast=63 saturation=63 hue=0
May 15 00:08:26 mythtv-backend-1 last message repeated 3 times
May 15 00:08:26 mythtv-backend-1 kernel: cx25840: decoder disable output
May 15 00:08:26 mythtv-backend-1 kernel: cx25840: decoder enable output
This has been the case with the previous R5A12 as well.
Are these times as expected? If not, any ideas where I could begin to look (e.g. mythtv, ivtv, etc.) at fixing these?
