Hardware:
AsRock 775Dual-VSTA Motherboard
C2D 4300
2GB DDRII RAM
GeForce 6200 (AGP 8X)
Firewire PCI Card
PVR-350
Linux Distro: Feisty Fawn Ubuntu
MythTV version: 20.2-fixes
ivtv version: 0.10.1 (tagged release)
I am getting a bunch of errors in dmesg while recording. They are:
[958989.631007] ivtv0: All encoder MPEG stream buffers are full. Dropping
data.[958989.631011] ivtv0: Cause: the application is not reading fast
enough.[959650.647559] ivtv0: All encoder MPEG stream buffers are full.
Dropping data.[959650.647563] ivtv0: Cause: the application is not reading fast
enough.
I have DMA working on all hard drives and I also set the PCI latency on all my
ide/sata controllers to 176 as suggested in a many mailing list posts. The
latency for the card is at 64 per ivtv info in dmesg.
So I read on the MythTV PVR-350 WIKI that I could add options for the ivtv
module to use instead of the defaults for the buffers. Well I couldn't find the
file that the wiki tells me to add the options to (/etc/mythtv/modules/ivtv)
but I do have a /etc/modprobe.conf file that has other options for lirc module
and for my serial irblaster module. I added the following there:
options ivtv yuv_buffers=32 mpg_buffers=16 vbi_buffers=16 pcm_buffers=16
dec_osd_buffers=2
but when I restart the dmesg output shows this:
ivtv: Unknown parameter `yuv_buffers'
so then I figured I didn't even need the yuv_buffers to be set since I don't
use /dev/video32 so I removed that from the line and left everything else.
Another restart and now I get this error:
ivtv: Unknown parameter `mpg_buffers'
When I leave these options in the modprobe.conf file, my card doesn't even show
up in mythtv and when I issue lsmod | grep ivtv, it's not even being loaded.
Apparently trying those options is preventing the ivtv module from being loaded.
Obviously I am not understanding something. I read the module.txt located in
/usr/share/doc/ivtv-utils/ and it actually states that all the options I am
trying to use are valid options so can please someone help me with this issue.
I would greatly appreciate it.
