[mythtv-users] [ivtv-users] Revised documentation on ivtv on Fedora Core/RHEL

[Axel Thimm]

Hi,

in the last weeks I have seen several bug reports on the usage of ivtv
on Fedora Core/RHEL. I just edited the wiki pages to reflect this:

http://ivtvdriver.org/index.php?title=Howto%3AFedora&diff=1881&oldid=1485

To sum it up:

o ATrpms always shipped modules that would conflict with kernel or v4l
  with a different name (e.g. foo was named foo-ivtv). The default
  setup was therefore to use what the kernel provides.

o If a user required the use of the ivtv supporting module he would
  have to add an "alias foo foo-ivtv" line to divert the module to the
  ivtv one. Almost all modules were required until 0.4.x.

o With 0.4.x some modules/fixes made it into the kernel, ivtv detects
  this and doesn't build them (for newer kernels).

That means that if you previously had to use alias lines to enforce
the usage of ivtv's versions of these modules, now the same lines
disable those modules completely if ivtv doesn't ship them anymore.

Check your ivtv's kmdl contents with

rpm -ql ivtv-kmdl-`uname -r`

If there is more than ivtv.ko in them (there currently still is) you
*can* use alias lines to override the kernel's with ivtv's.

Make sure you don't have alias lines pointing to non-existent ivtv
kernel modules!

Future kernels will have even better support for ivtv, so always
perform the above check when upgrading your kernel (e.g. 2.6.16 will
most probably have everything in place, so ivtv package will have no
supporting modules at all anymore => no alias lines at all, too).
