Re: [vdr] pvrinput radio - need analogradio??
It looks like this plugin does something wrong with the analog radio on the OEM PVR-150 card.

[vdr] xmltv2vdr speedup and modification
Hi, I'm the original author of xml2vdr (for my sins!), thanks for working on it and improving the performance. If everyone is happy with this new code release and it really improves the speed I'll wrap it up and make a formal release and get Klaus to add it to the VDR FTP site. As a lot of people seem to use xml2vdr, perhaps it would be good to resurrect it and keep it formally updated?

So I modified it a little to avoid reading all the xmltv file for each channel defined in the channels.conf. The result is good : I can process my 5Mo xmltv file in less than 10 minutes whereas it took at least 1 hour with vanilla 1.0.6 release. I also added support for sub-title in the xmltv file (I think someone already posted about that in the list). I only use it for one week so it can still be buggy. I'll be happy to take care of any bug found. Hope this helps those with old hardware like me.

Re: [vdr] pvrinput radio - need analogradio??
I use this modified code in device.c (pvrinput):
bool cPvrDevice::Tune(int freq)
{
struct v4l2_frequency vf;
int freqaux = freq;
memset(&vf, 0, sizeof(vf));
vf.tuner = 0;
if (freq > 18)
vf.type = V4L2_TUNER_ANALOG_TV;
else
{
vf.type = V4L2_TUNER_RADIO;
freqaux = freq * 1000;
}
vf.frequency = (int) ((double) freqaux * 16.0 / 1000.0 + 0.5);
if (IOCTL(video_fd, VIDIOC_S_FREQUENCY, &vf) != 0)
{
log(0, "Error tuning to %d: %s", freq, strerror(errno));
return false;
}
frequency = freq;
return true;
}
But I have some problems with radio(pvrinput), and xineliboutput.

The problem I have is that after a while sound is distorted an finally sound
stop. There is not any messages in the log. I don't know if is pvrinput or
xineliboutput fault.

Something more what you can do (just by looking source you provided)..
--
Caching of &xmltime2vdr, like
return $timecache{$xmltime}->{$skew} if defined
$timecache{$xmltime}->{$skew}
$secs = &Date::Manip::UnixDate($xmltime, "%s") + $skew*60;
$timecache{$xmltime}->{$skew} = $secs
return secs;
But it depends on how much this function is called.. But hash lookup is probably
faster than running UnixDate from library. So it is a memory tradeoff.
I still haven't tested it but I doubt it'll help . I'll check later.
I see that there is still some basic Perl based optimizations for this.
For example there is browsing through @xmllines array, and every iteration
you recompile *ALL* regexp's. That is as many times as @xmllines has lines.
And if one recompile takes 1ms -> you waste time @xmllines * 1ms just for
compiling and not doing anything usefull.
Perl switch "o" is recompile once flag, use that everywhere where it is
possible. Variable is not a problem unless variable changes in every iteration.
[]
I didn't know that (I'm not really a perl guru ... far from it). I'll
update my version. But it didn't help at all with my benchmark.
--
As there is many times $xmlline is matched with regexps etc. You should
experiment
with "study $xmlline;" after chomp $xmlline. Study makes internal search tables
for string matches. So see which way the code is faster, with study or without
study. Use Unix shell's time-command for this. For extra boost with study you
probably would need to take away subroutine "xmltvtranslate" as for it $xmlline
is copied to subroutine's parameter space, and what is matched. And study would
not affect it. So instead of calling "$xmlline=xmltvtranslate($xmlline);"
cut&paste
subroutines code here, and use $xmlline instead of $line.
foreach $xmlline (@xmllines)
{
chomp $xmlline;
study $xmlline;
$xmlline=~s/und uuml;/ü/go;
$xmlline...
This isn't pretty but could probably help a bit. You save time for @xmllines
times calling
subroutine, and study would help you a lot as you use the same string all the
time.
I'll check that later.
For constant string you could use ' ' instead of " ". " causes string to be
evaluated for variables
if ( $chanCur eq "" ) --> if ( $chanCur eq '' )
But this would be very minor effect..
I'll surely be too lazy to test that. sorry.
Split is heavy operation because of creating arrays, but you can limit it.
( $null, $xmlst, $null, $xmlet, @null ) = split(/\"/, $xmlline);
=> ( $null, $xmlst, $null, $xmlet, $null ) = split(/\"/, $xmlline, 5);
or even using regexp for this. I don't know input line for this, but if it is
foo,"something","something",...
($xmlst,$xmlet) = $xmlline =~ m:\"(.*?)\",\"(.*?)\":o;
or probably combine 2 regexp to a single
($xmlst,$xmlet,$channel) = $xmlline =~
m:\"(.*?)\",\"(.*?)\".*?channel=\"(.*?)\":o;
--
Again something very weird:
if ( ($xmlline =~ /\/, $xmlline);
( $vdrtitle, @null ) = split(/\(.*?)\:o;
Same for XML subtitle
SVDRPsend("T $1") if $xmlline =~ m:\(.*?)\:o;
Yes I'll also prefer shorter code. I'll check further if something
like is also allowed to adapt the regex. For
information that change has no impact on my bench.
Generally
if ( ($xmlline =~ /\/, $xmlline);
( $vdrdesc, @null ) = split(/\
Agree. I'll try to modify it.
Some logical errors
if ( ($xmlline =~ /\ if ( ( $chanevent == 0 ) && ($xmlline =~ /\
In fact the check $chanevent == 0 is only usefull if the xml is not
well formed so it doesn't change anything.
Then
elsif ( $chanCur ne $chan )
{
SVDRPsend("c");
SVDRPsend(".");
SVDRPreceive(250);
I think programmer wanted outout of "." -command, and see if it's status is 250?
But now I think code is checking status of "c" -command? As socket is not read
between calls, and there should be data in buffer for c-command. But I cannot be
sure as I don't know SVDRP command that well.
> c
< 250 foo
< 250-foo
> .
< 354-not ok
It could still succeed if from socket buffer "250-" is read. Also the 2 substr
calls
in SVDRPreceive is a bit weird, but I am uncertain if regexp would help that.
At least
change "-" to '-'.
I have no answer about this as I didn't modify that code . it
seems to work so for now I don't touch it.
There is a LOT to improve, but if you do these, you Celeron will fly. I hope
you'll get
to minute scale (or even better). Look with "time xmltv2vdr" to see how

I think this don't work. I use freq >18 because 18 is the max range
for FM.
You can also use:
if (radio_fd >= 0)
radio
else
tv

It's tuning ok now - but I still get no audio.
I'm struggling with this. I somehow need the plugin/VDR to listen to
effectively tune and then do an equivalent of:
aplay -f dat < /dev/video24
how do I do this??

I've found some weird stuff. When vf.tuner is set to V4L2_TUNER_RADIO the
freq seems to be a factor smaller. In experimenting, I find if I set the
channels between 8800 & 10800 (for 88-108Mhz - looks like this is
set as Hz ???) monitoring what's been set on the PVR-150 with 'v4l2-ctl
--all', I see these values set the correct freq and I get a 50% or better
signal strength. What's more, the 'v4l2-ctl --all' matches what's set
with a 'ivtv-radio -f90.0'.
Problem is, no audio is output!! It looks like the v4l2 tuner is set to
radio, the tuner is set to 90.9Mhz, but it's trying to play the stream
from /dev/video0 rather than /dev/video24. Does this make sense??
