    I have bttv based card (Avermedia) so to use radio i add the following to
    /etc/modprobe.d/aliases (for Debian and friends)

    options bttv radio=1

    more info about driver options can be obtained with modinfo, for example:

    /sbin/modinfo bttv

    Hi!

    I hope, the PVR setup is now documented much better within KRadio (look at the V4L and Streaming Plugin config pages), on the KRadio Website (FAQ) and a dedicated README.PVR in the source archive.

    Unfortunately, I don't have a PVR card, thus I could only extrapolate from some users reports and use /dev/urandom instead of a real /dev/video24 (or similar). Hope it works,otherwise please let me know more details or let's think about ways how I could get a PVR card ;-)

    Here is the content of the README.PVR file:

    1) Configure the Streaming Plugin:
    - add your device to the capture URLs (/dev/video24, /dev/video32 and /dev/urandomshould already be there)
    - configure the right sound sample format/rate/... for your radio card
    2) Configure the V4L2 Plugin:
    - Select your favourite PCM Sound Card as playback device
    - Select your favourite PCM Mixer Channel as playback channel
    - Select the Streaming Plugin as Capture Device
    - Select the radio/video device (e.g. /dev/video24) as capture mixer channel
    - enable the active playback checkbox. KRadio will now record from the capture channel internally (not to a file) and send the data to the playback PC channel.
    3) Done. Your kradio should be now usable for PVR cards. If not, please provide me details on your setup or perhaps even a card to test it.


    With best regards,

    Martin

    Hi!

    Just a quick guess: From your dump I saw that you are still using the old snapshot (r562). There have been *lots* of known problems inside r562, that snapshot was just send out to show that work on kradio is continuing. The most recent snapshot from yesterday (r630 thus almost 70 svn commits of improvement!) should fix most issues.Hopefully ;-) Please give it a try!

    Yes, you are right ;o) I forget to upgrade the kradio ;o) Well, it works now much better with the r630 ;o) I'm able to add devices into the Capture URLs list, tune stations and play them. Great work! I have also found a few things which could be fixed:

    There is missing the Power icon in the Radio Display.

    I have tested also the LIRC support and it works in general. But when I have a global program to control the volume, the kradio4 is still trying to capture the volume buttons over which leads in freezing state. Further, when I want to change the channel over the Ch+, Ch-, it is seeking through the channels and it never stops.

    Thank you for the new version! It is great to have kradio for KDE4 and on top of that with support of PVR cards!

    Hi!

    Some questions:
    * how is "the global program" controlling your volume? Does it react on LIRC commands? If yes, you could either adapt your .lircrc file so that the volume commands are not sent to kradio or tell kradio to ignore the respective lirc-commands (see lirc config page)

    * What do you mean by "seeking through channels ... and it never stops"? Is it a zapping through all known channels? Or is it the channel search over the frequency range? If its the latter one, does it stop at the end of the frequency range?

    BR, Martin

    The global volume control is the following:

    begin
    prog = irexec
    button = Vol+
    config = avolume -q -c Master -i 1 -x
    repeat = 0
    end
    begin
    prog = irexec
    button = Vol-
    config = avolume -q -c Master -d 1 -x
    repeat = 0
    end
    begin
    prog = irexec
    button = Mute
    config = avolume -q -c Master -m -x && sleep 1
    repeat = 0
    end

    The aim is to control volume by one prog globally and not in each application supporting LIRC separately.

    Concerning the second problem, yes it does zap through the known channels in a loop.

    Some more questions on the zapping-look:
    * what are your lirc repeat settings for the ch+/- keys?
    * is the GUI of kradio still responding? Can you switch of the radio or look into the error log? There should be log messages for each licq command in the debug view. Could you send me that debug output, please?

    I just tested the r649 and the LIRC still doesn't work. My lircrc is the following:

    begin
    prog = irexec
    button = Radio
    config = kradio4 &
    mode = kradio
    repeat = 0
    end
    begin kradio
    begin
    prog = kradio4
    button = Exit
    config = QUIT
    repead = 0
    end
    end kradio

    and when I press the Exit button on my remote controller, kradio get frozen and the following message appears many times in the console:

    kradio4(7235) IErrorLogClient::sendLogDebug: "2009-02-21T16:15:34 Debug: LIRC: Back/Exit"

    Do I need to define the mode section in the lircrc file? Or it is sufficient to define the section with irexec and the rest define in the kradio? I mean to define the "Exit" button directly in the kradio LIRC configuration as "Quit KRadio"?

    Btw. the Quit button is still missing an icon ;o)

    hmm... strange... can't reply more than this level... therefore replying on my own message...

    Sodele... just a short note on the LIRC issue: Finally I could reproduce that. The reason is that in the kradio mode of the lircrc, an entry like

    begin
    prog = kradio
    config = eventmap
    repeat = 1
    end

    is missing compared to my setup. Although KRadio is "supposed" to work without that entry, this could serve as a workaround at least until the issue is fixed.

    Thanks for your feedback and debugging!

    I had in the Capture URLs list the /dev/video24 by default so I have managed to set up the rest of options by your description.

    The result is that I'm able to search for stations but no sound is coming out of it. Maybe some mixer setting is wrong?

    When I'm trying to adjust the mixer and when I do Apply, the kdradio4 get frozen (the GUI can redraw itself but I can not click on any button or close it). Maybe it has something to do with the messages in the console:

    QPainter::begin: A paint device can only be painted by one painter at a time.

    Hi!

    As noted in the prev. note, the latest snapshot r630 should fix most issues and be usable for productive use now. The only thing that worries me a bit is the warning of the QPainter... haven't seen that yet... is it still in r630?

    Best regards, Martin

    Yes, the message is still there even in the r630:

    QPainter::begin: A paint device can only be painted by one painter at a time.

    It is generated approximately 20 times per second.

    Hmm... although I could not reproduce it, I found a place which could cause this behaviour with some high probability. Seems to depend on Qt Version (I'm currently using 4.5rc1 from kde-svn). Will be fixed in next snapshot.

    Thanks for your feedback!

    I'm using KRadio on KDE 3 and it's great!!
    A KDE 4 version is a great news! Thanks!

    Could you keep the convention of making the snapshot packages? I mean to have there only the kradio4-snapshot-2009-02-19-r630 directory and not all the /home/... structure.

    Ebuild for Gentoo users is in the Bugzilla (http://bugs.gentoo.org/show_bug.cgi?id=259704) or in the kde-testing overlay.

    How do you like Plasma 5?
     The best KDE Desktop ever.
     Definitely a nice improvement.
     Not decided yet. Haven't tried it yet.
     I do not like some of the changes.
     KDE is taking the wrong way.
     I am still sticking with KDE 3.5.
     I have no opinion, but wanted to vote anyway.
