| Post subject: | how to update bttv? (need newest tuner patches) |
knoppmyth-guru's: i've been having some problems getting a brand-new-as-of-last-week PVR350 going. this is in stark contrast with my older PVR-350 which works superbly with knoppmyth. based on some feedback i've been getting on the ivtv mailing list, it seems that it is necessary for me to update (or patch current) bttv so that the tuner module will recognize the newest flavor of PVR350. see http://www.poptix.net/ivtv/Sep-2004/msg01837.html and http://www.poptix.net/ivtv/Sep-2004/msg01812.html and http://www.poptix.net/ivtv/Sep-2004/msg01842.html however, i'm a little unsure about how to go about updating bttv within knoppmyth. could someone be so kind as to walk me through the steps to do so? something more than "you'll need to recompile the kernel" would be appreciated. thanks much, jim |

With a pvr350 you need to update the IVTV driver not the Bttv driver. Here is a link to the most current ivtv drivers http://67.18.1.101/~ckennedy/ivtv/ I believe you can find help on installing them by doing a search of this site. Good luck!! |

Sorry, I can't help with the bttv driver. I am having trouble with the current bttv driver too. I am using bttv-9.15 because it seems to work the best but it seems to be buggy. I have even tried bttv-7.1?? but it didn't work very well with ivtv. There are new versions of video4linux available but I haven't been able to get those to compile on my myth box. I think it may be necessary to patch the kernel to get those drivers to compile. kind of seems like a lot of trouble....... |

I'll tell you what I did but that doesn't mean that I really know what I am doing... As an example, go to the /usr/src directory and you will find a compressed file contianing bttv-9.15. uncompres the file tar xzf bttv-xxxxxxetc enter the directory then type Make as a super user type Make install Now you just need to do the same thin with other versoins of the file. I did not have to recomplie the kernel. I hope this helps... |

I have the same problem as the original post. I have a newer pvr-350 with the type 47 tuner. I am running r4v4.1. I unpacked the linux sources in /usr/src and tried downloading a recent video4linux snapshot from linux.bytesex.org. But it wouldn't compile...maybe the latest snapshots don't support 2.4 kernels. Can someone help with how-to on patching tuner.c and recompiling the kernel or just compiling/installing a newer tuner.c? Thanks, Rich |

rich, are you saying you have the "same problem" as in "NO AUDIO" ? everything else (video out to TV etc) works on my system. i have a "duplicate" system, with an older PVR350, and it works 100%. thanks jim |

Jim, I think I may have written you directly from the ivtv list. No, I didn't have the same problem....I had poor tuner performance (bad audio and video). I recompiled tuner.c with the recent LG TAPE patches and things seem to be working ok (although picture quality on some channels could be a bit better). I would post the tuner.o file here, but I don't think I can attach a file to this post. Thanks, Rich |

I did a search for tuner.c and could not locate it on my system (R4v5). I also went up to ivtv rc2.0 and still did not come up with a tuner.c file. I had read in several places tuner.c would have to be patched for the new pv250 (2002N) but can't find it. Thanks |

If I remember correctly, I unpacked the linux sources found in /usr/src. The tuner.c file is located drivers/media/video or something like that. I then did a 'make modules' for lack of an easy way to just recompile the one file. I then installed the resulting tuner.o by manually copying it to the appropriate path in /usr/lib/modules. Hope this helps. Sorry for the lack of exact steps, but this is just from memory. |

Thanks for the reply. Unfortunately I loaded a few other items and am now looking to find out how to increase the size of my root partition without doing a reinstall. Thanks again for the reply. |

First, you're on the right track, though I had to apply the patch by hand, as the patch supplied (the one with 2002N in the subject) was a patch against a slightly newer source version. This required a few changes, among them that the TAPE stuff ended up being element 44 in the array, so I altered the constant to 44 instead of 49 Second, the actual location of all the kernel files isn't really critical. If you want, you can install the kernel sources in some conveniently large partition (say, /myth?) and create a symbolic link from /usr/src/ to the actual location. This gets around your space problem. Try the following (approximate) commands. There will be some typos but you can probably get it to work. Code: mkdir /myth/src cd /myth/src tar -xjf /usr/src/linux-2.4.25-chw.tar.bz2 ln -s /myth/src/linux-2.4.25-chw /usr/src/linux cd /usr/src/linux vi drivers/media/video/tuner.c apply edits necessary to add magic constants for your tuner type make modules be patient for a while cp drivers/media/video/tuner.o /lib/modules/drivers/media/video Third: Be very careful about which patch posting you use. An early posting was almost entirely correct except for one hexadecimal value that got screwed up. Look for postings that mention a typo being present that give the proper value. Any further problems, post again with your results so far. When I get home I can look up the exact patch I made.[/code] |
