Re: [vdr] pvrinput radio - need analogradio??

2007-02-13 Thread Simon Baxter

It looks like this plugin does something wrong with the analog radio on
the OEM PVR-150 card.

With channels.conf set to:
Radio 91ZM:90900:I999C0:C:0:0:300:305:A1:12003:1:1007:0

v4l2-ctl --all   looks like this:

Audio input : 0 (Tuner 1)
Frequency: 1454 (90.875000 MHz)
Video standard = 0x00ff
PAL-B/B1/G/H/I/D/D1/K
Tuner:
Capabilities : 62.5 kHz multi-standard
Frequency range  : 44.0 MHz - 958.0 MHz
Signal strength  : 0%
Current audio mode   : mono
Available subchannels:


Where ivtv-radio -f90   looks like this:

Audio input : 0 (Tuner 1)
Frequency: 1454400 (90.90 MHz)
Video standard = 0x00ff
PAL-B/B1/G/H/I/D/D1/K
Tuner:
Capabilities : 62.5 Hz stereo
Frequency range  : 65.0 MHz - 108.0 MHz
Signal strength  : 50%
Current audio mode   : stereo
Available subchannels: stereo


it appears pvrinput isn't setting the right audio mode/sub channels etc??


Any ideas?

PS.  It looks like analogradio  plugin is no longer supported?  Is also
doesn't support ALSA.

?

 I've asked this before, last year, but never had a response.

 How do I configure radio channels in VDR.

 My channels.conf has:

 Classic Hits:9:I999C0:C:0:0:300:305:A1:12003:1:1006:0

 But I think I'm picking up the wrong device, as I hear no audio.  I have a
 single PVR-150 with ivtv and the following devices:

 /dev/video0
 /dev/video24
 /dev/video32

 When I do a 'ivtv-radio -f9' I see:
 aplay -f dat  /dev/video24#which works

 Sowhat should my Parameters be??

   C0   - Input 0
   C12  - Input 1
   C23  - Input 2
   C34  - Input 3
   C45  - Input 4
   C56  - Input 5
   C67  - Input 6
   C78  - Input 7
   C89  - Input 8
   C999 - Input 9

[vdr] xmltv2vdr speedup and modification

2007-02-13 Thread Morfsta


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?

Regards,

Morfsta

Hi,

I recently worked on xmltv2vdr.pl (version 1.0.6) and checked why it
was so slow on my mighty Celeron 233. 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.

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); 
cutpaste
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 =~ /\title/ ) )
{
#print $xmlline . \n;
( $null, $tmp ) = split(/\/, $xmlline);
( $vdrtitle, @null ) = split(/\/, $tmp);

# Send VDR Title

SVDRPsend(T $vdrtitle);
}

Why not?

SVDRPsend(T $1) if $xmlline =~ m:\title\(.*?)\/title\:o;

Same for XML subtitle
SVDRPsend(T $1) if $xmlline =~ m:\sub-title\(.*?)\/sub-title\:o;


Yes I'll also prefer shorter code. I'll check further if something
like title lang=en is also allowed to adapt the regex. For
information that change has no impact on my bench.


Generally
   if ( ($xmlline =~ /\desc/ )  ( $desccount == $dc ))
{
( $null, $tmp ) = split(/\/, $xmlline);
( $vdrdesc, @null ) = split(/\/, $tmp);

this is not a clever way to parse XML data in Perl. Just us regexp's which
match strings with Boyer-Moore algorithm (same as Unix grep) and compile once.



Agree. I'll try to modify it.



Some logical errors

if ( ($xmlline =~ /\programme/ )  ( $xmlline !~ /clumpidx=\1\/2\/ )  ( 
$chanevent == 0 ) )

= if ( ( $chanevent == 0 )  ($xmlline =~ /\programme/ )  ( $xmlline !~ 
/clumpidx=\1\/2\/ ) )

so program execution can skip if $chanevent != 0 much faster.
So Regexp would not be ran. This is normal short circuit operation.



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

Interesting, what version of Perl are you running if those
changes don't do anything?

Futher improvement is that now it is unnecessary to read whole
XML-file into memory, as the file is linearly scanned through. So no
need to waste 5MB of memory if you are short of it.

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??




 Thanks Jose - that's a great help!

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??
