Hi,
I've managed to compile the "official" saa7134-0.1.5 release against
2.4.19-pre4 with all the 0?*diff patches. However, I find that it
doesn't work as reliably compared to the older March 11 snapshot
compiled against 2.4.19-pre3ac3.
I've backported the S-Video support to the Mar 11 snapshot (ignoring
the ioctl changes) and it works fine.
The issues:
1. With saa7134-0.1.5/2.4.19-pre4, XWindows 4.1, NVidia driver
(for Xv support), xawtv TV channel changes are not working. It works
fine running with just fbtv on rivafb. There seems to be some
interaction between pre4 and XWindows. I don't have this problem
in 2.4.19-pre3ac3.
2. S-Video input gives a grainy picture with the saa7134-0.1.5/2.4.19-pre4
config. This does not occur with the saa7134-mar11-snap/2.4.19-pre3ac3.
What I mean by grainy is that the color intensity seems to be
modulating along the scan line.
The brightness level for S-Video is also less than for Composite
Input for the same setting, but I suppose it's not so critical.
3. Updating the saa7134-cards.c cards entry is not reflected properly
via 'v4lctl list' after a 'rmmod saa7134 tuner v4l2-common ...' while
running under XWindows. E.g., while modprobing the official
saa7134-0.1.5 module vs. my modified saa7134-0.1.5-fv2k module, the
availability of the S-Video input is not updated properly.
This does not occur in console mode while not running XWindows.
i.e., I can switch saa7134 modules and get the correct Video inputs
list when in console mode, but not in XWindows.
Is the v4l ioctls flushed properly when using rmmod under XWindows?
(lsmod indicates that the modules are removed).
4. vbi support on FV2K still not functional. 'alevtd -d' after I've tuned
into the correct TV channel complains about "insufficient number of
periods..."
What am I missing?
5. I've fixed up the source inputs for FV2K, for Composite and S-Video.
Also included is the external audio muting patches for FV2K.
