Hi all,
I've finally put up my fixes for Closed Captioning support in
this 'bleeding edge' tree:
http://www.linuxtv.org/hg/~hverkuil/v4l-dvb-vbi
Build instructions are here:
http://www.ivtvdriver.org/index.php/Download#Bleeding_Edge_driver
Please test and let me know how well it works! I've tested it
with both saa7115 and cx2584x-based cards and they seem to work
equally well, so that's promising.

Hans,
After 24 hours of use, it looks like its working. I have my
PVR-250 in the same computer as a PVR-150 and the captions are
just as good. I also havn't had any tinny audio from the -150 yet,
or any DMA Timeout errors.
I'm using Fedora core 8 with kernel 2.6.25.9-40 and mythtv
0.21-fixes from atrpms. The system is a dual socket Athlon XP
I will keep my eye on it for anything strange.
Sounds good. If I don't get any bug reports, then I'll probably
commit this in 1-2 weeks.
Regards,
Hans
Okay,
I've been using this version of IVTV for 16 days. I have noticed
a bunch of errors still happen, although I have workarounds that most
don't bother me.
My MythTV backend system specs.
Dual Athlon XP Mobile 2500+ on an Asus A7m266-D motherboard. (AMD
Highpoint RocketRAID PCI-X SATA 1 raid controller
one 150GB Raptor for boot
two 500GB Seagate 7200.10 in raid0 for video storage
one PVR-150 OEM
one PVR-250 Retail
First, what was fixed. The closed captions on the PVR-250 are now
flawless, and identical to the PVR-150.
Very good.
Second, the PVR-150 sometimes has tinny audio. I searched the
ivtv-users and mythtv-users for solutions, but they all involved the
tuner, so I created my own workaround.
The audio sounded to me like when Dolby NR is enabled while recording
a tape, but not while playing back. so from my channel change script,
I spawn another script that runs v4l2-ctl -c audio_emphasis=0 after a
few seconds.
The audio from the PVR-250 starts as mono, until I run v4l2-ctl -d
/dev/video1 -t bilingual in the same style of script
I also have found every few weeks I get 0 byte files recorded by the
2nd tuner, as well as "DMA Timeout" in dmesg. From the lists, I have
been told this is a motherboard problem, which I'm planning on
upgrading anyway.
If you need any other information, let me know. I'll be happy to help
you troubleshoot.
The remaining problems were all existing problems, right? Not newly
introduced problems by this change?
Regards,
Hans

Yes,
