Public bug reported:
Binary package hint: ivtv-utils
I was trying to apply some parameters for my PVR-350 so I could rid my
MythTV recordings of pauses and dropped frames and according to
modules.txt located in /usr/share/doc/ivtv-utils/ (as well as the MythTV
PVR-350 Wiki) I was to be using the following parameters for increasing
the buffers.
yuv_buffers 2 32
mpg_buffers 4 16
vbi_buffers 2 16
pcm_buffers 2 16
dec_mpg_buffers 1 1
dec_yuv_buffers 1 1
dec_vbi_buffers 1 1
dec_osd_buffers 1 2
I was to add this line to my /etc/modprobe.conf
options ivtv yuv_buffers=32 mpg_buffers=16 vbi_buffers=16 pcm_buffers=16
dec_osd_buffers=2
but when using those parameters ivtv wasn't even loading. I was getting
the following error in dmesg:
ivtv: Unknown parameter `yuv_buffers'
The following is what modinfo ivtv returns:
parm: enc_mpg_buffers:Encoder MPG Buffers (in MB)
Default: 4 (int)
parm: enc_yuv_buffers:Encoder YUV Buffers (in MB)
Default: 2 (int)
parm: enc_vbi_buffers:Encoder VBI Buffers (in MB)
Default: 1 (int)
parm: enc_pcm_buffers:Encoder PCM buffers (in MB)
Default: 1 (int)
parm: dec_mpg_buffers:Decoder MPG buffers (in MB)
Default: 1 (int)
parm: dec_yuv_buffers:Decoder YUV buffers (in MB)
Default: 1 (int)
parm: dec_vbi_buffers:Decoder VBI buffers (in MB)
Default: 1 (int)
it really needed to be enc_yuv_buffers for encoder buffers and
dec_yuv_buffers for decoder buffers. I think the modules.txt file should
be updated to reflect what parameters are correct for the ivtv module.
