I'd imagine anything audio related would be handled by ALSA, so perhaps there 
is a driver you are missing or you might be able to use the line in on an 
existing sound card instead to record the audio.

Hi,

Actually, that is what I _have_ to do with my old TV card.
It doesn't have a input for audio and no internal mixer, so I have to record the sound directly from the soundcard.

I use menconder to do just that:


mencoder tv:// -tv driver=v4l2:device=/dev/video0:input=3:width=640:height=480:alsa -oac mp3lame alsa -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=8800:vme=3 -o outfile.avi

The man page for mencoder is quite undertandable, if you want to customize the parameters.

Regards,

Marco

I'll try something like that. What do you think of this error message:

Not really. I think that man page is a big mess. ;-) Though one can find one's 
way around in it with tons of time.

It seems that the format is not understood ( duh! ;) ) by mplayer. I don't have this card, my card is an old analog card. So maybe you have the stream alread in mpeg format. I believe I cannot help you more. Sorry.

Hello Uwe,

In my experienes, you need to build a 'mixing studio' or at least 
a very simple A/V mixing system. There are too many A/V tools to use.
I'd first look at the MoBo book and see what onboard hardware you have
plus 'lspci' -v and 'lshw'. Using the core mobo chips is usually the
most straightforward. Also look at what sound cards you have.


Then 'eix <keyword>' using mixer, audio, jack, alsa etc to 
discover the various packages and try them out. Also use
google to search for <keywords> + <audio chips> where
audio chips are the actual chips you find on your hardware.

'kmix' is a quick and simple mixer that often provides control
over the various audio chips. You'll also have to rebuild your
kernel many times to find the right combo of drivers to compile
in and/or load as modules. Often the various audio chip drivers
conflict at the kernel, udev or application level. There is
no 'silver bullet' to build a mixer/mux for A/V, in my experience.
It all depends on what you need. Moving over old movies, one
of your greatest challenges will be keeping the audio and
video synchronized over the duration of the recorded stream.


hth,

James

this is all completely irrelevant to the question.

The PVR-150 muxes the audio and video into an mpeg stream.

When using "composite in" the sound should be coming in the "line in"

However your driver may need to be switched to the right device, use ivtvctl

ivtvctl -A   - lists the audio inputs
ivtvctl -Q   - tells which one it is switched to now
ivtvctl -qn   - switches to input n

Uh-huh! I'll give it a try.

The other big question is, what to make of this error when using something 
like "mplayer tv:// blablabla":

v4l2: current audio mode is : MONO
v4l2: ioctl request buffers failed: Invalid argument
v4l2: 0 frames successfully processed, 0 frames dropped.


The ioctl failure doesn't seem to be a permission problem.

Hm...
uwe@uwix ~ $ ivtvctl -A
ioctl: VIDIOC_ENUMAUDIO
        Input   : 0
        Name    : Tuner 1

        Input   : 1
        Name    : Line In 1

        Input   : 2
        Name    : Line In 2

There is only one Line IN socket. Anyway, I tried both with "iivtvctl -qn". 
Still no sound when doing "mplayer /dev/video0", and "mplayer tv://" gives me 
that damn ioctl error (see my other mail).

well I just learned something new:

nick@media:/var/log$ ivtvctl -Y
ioctl: VIDIOC_QUERYCTRL
Brightness = 383
Contrast = 63
Saturation = 63
Hue = 0
Volume = 58880
Mute = 0


So there are volume and mute controls that are configurable from ivtvctl, like this:

ivtvctl -y mute=1   (will mute the output - set -0 to unmute)
ivtvctl -y volume=integer.

The volume allegedly has a range of 0-65535

Check them out, the vol may be zeroed, or the mute set.

uwe@uwix ~ $ ivtvctl -Y
ioctl: VIDIOC_QUERYCTRL
Brightness = 128
Contrast = 64
Saturation = 64
Hue = 0
Volume = 60928
Balance = 32768
Bass = 32768
Treble = 32768
Mute = 0

It isn't muted, and the volume seems to be quite high. :-(

Yes. If I plug that line into Line IN of my soundcard I get audio. I actually 
tried to feed composite into the TV card and audio into my soundcard. 
Used "mplayer /dev/video0" and it kind of worked. But it isn't a solution for 
two reasons:

1. 
Audio and video are far out of sync that way.

2.
My goal isn't to watch tapes but to burn old tapes to DVDs. For that, I need 
the MPEG2 stream coming out of /dev/video0 to be combined video and audio.

Yes, exactly. There is a delay for buffering or processing or something
inherent in the pvr card. There is no such delay through the sound card.

I suppose the card could be broken. Sometimes they are. Any chance of
taking it back to the shop and asking for another one?

Or *cough* trying it in windows?

I also wonder whether you should try either the mythtv-users list or the
ivtv-dev mailing lists. Probably the first thing they will ask for is
the log information from dmesg between these two lines:

ivtv:  ==================== START INIT IVTV ====================

necessary info

ivtv:  ====================  END INIT IVTV  ====================

Just looking at this I see mine contains:

tveeprom 0-0050: audio processor is CX25843 (idx 37)
tveeprom 0-0050: decoder processor is CX25843 (idx 30)


Also I note via lsmod that I have a cx25840 module loaded. Presumably
that takes care of the sound. It may pay to look at your output - there
are many variations of chipsets on these cards, particularly between PAL
and NTSC models.

Uwe I was just cruising the mythtv-user mailing list and found a tale
much like yours in terms of audio on a PVR-500 card (a PVR-500 is
essentially two PVR-150's on one card)

The whole 9 yards is here:

http://www.gossamer-threads.com/lists/mythtv/users/204597

But to cut a long thread short there was a firmware problem. The PVR
150/500 needs to load two lots of firmware, one for the audio and the
other for video. It may be that your audio firmware is not being loaded.

Very carefully check your dmesg for errors involving the firmware for
any of the ivtv related modules.

FYI here is the IVTV dmesg log for my card, I have marked the relevant
lines ********

Mine looks pretty much the same except that it detects the remote. Firmware 
gets loaded, all drivers get loaded, no errors.

Meanwhile I do have audio but very very faint if i raise everything to maximum 
(mixer, speaker amplifier, ivtvctl). 

I don't know. Maybe the hardware is fried.

The guy on the mythtv list thought his was OK too until someone else spotted the error - I'm not saying you cannot read a log file, but y'know it happens to the best of us :-(

As far as i recall you have been trying so far with composite/line in. Is it worth trying the tuner?

What sort of input does your line-in have? Mine is two RCA plugs, but I have heard of them having the 2.5mm stereo plugs too (like a headphone socket on a walkman). If so, make sure the plug is the right one.

Not sure where else to go from here, except back to the vendor.

Well, I am not interested in watching TV. Even if the tuner works that doesn't 
necessarily mean that the hardware dealing with composite and Line IN is 
working properly.

I may give it a try later but I don't even have an arial because I never watch 
TV. ;-)

The latter one - and yes, I think the plug is right.

Very recent ivtv, more so than mine. the website says it is only for 2.6.17, but you seem to fit the criteria.

Looking at the ivtv website did say this:
http://ivtvdriver.org/index.php/Troubleshooting

"Use the recommended firmware

    * In particular, if you are experiencing sound problems then first
make sure you are using the correct audio firmware. It is a known
problem with older versions that the audio standard is detected but
remains muted. It seems to be fixed with the latest firmware. "

How you tell whether the firmware you have is "correct" ? There are some checksums here:

http://ivtvdriver.org/index.php/Firmware#Firmware_Checksums

(Although I just checked mine, they do not match whats on the website,
but they work fine??)

It was only a suggestion to eliminate the possibilty of the cable or
plugs being faulty.

The whole difference between yesterday and today is that I tried to compile

Since I hadn't time to investigate, I just left it like that. Nothing

Audio quality is still poor, high noise level and it doesn't sound like 50Hz

Anyway, forward to the next step of creating a video DVD from that MPEG2

There is a current "scratchy" noise problem with PVR-150 drivers.

AFTER you have started playing/recording the stream execute 

ivtvctl -qX 

where X is the audio input you are using. This fixes it for me and a
number of other mythtv users. Some have even set up a cron script to
execute that command every 10 seconds.

To get as close as possible to a DVD compatible stream use 

ivtvctl -c stream_type=X where X is the stream type you want from :

/* Stream types */
#define IVTV_STREAM_PS          0
#define IVTV_STREAM_TS          1
#define IVTV_STREAM_MPEG1       2
#define IVTV_STREAM_PES_AV      3
#define IVTV_STREAM_PES_V       5
#define IVTV_STREAM_PES_A       7
#define IVTV_STREAM_DVD         10
#define IVTV_STREAM_VCD         11
#define IVTV_STREAM_SVCD        12
#define IVTV_STREAM_DVD_S1      13
#define IVTV_STREAM_DVD_S2      14

I cannot for the life of me remember whether you want 10,13 or 14.

Interesting. is there actually any comprehensive documentation about ivtv? I 
only found scratches and pieces.

Only what comes with it I think. The doc directory in the source is
worth a look.

This is also worth a look: http://ivtvdriver.org/index.php/Main_Page

The driver has been in such a rapid state of development that any
documentation would quickly be out of date. It is considerably more
mature lately.

The mythtv mailing list archives are also a very good source of
knowledge. I would say that a very big percentage of people using these
cards under linux do so in a mythtv box. The archives are very good and
appear here:

http://www.gossamer-threads.com/lists/mythtv/users/

simply running 

ivtvctl | less gives you a good idea of what you can control.

Well, yes and no. If the PVR-150 card does everything he
needs, with the available software packages that are stable with
that card, then you are right. And if the mobo's built in,
(if any) A/V hardware does not conflict with the PVR
card, then again you are correct. Sometimes the AV application
software gets confused between the mobo's A/V hardware
and the A/V hardware on the pci(PVR) card confuse the 
AV software.

My experiences with A/V manipulations on Linux always result
in using the hardware resouces of various cards and the mobo.
Every machine for slightly different purposes has resulted
in sometimes dramatically different hardware/firmware/kernel/driver/
/udev/appplication-software variations.

> The PVR-150 muxes the audio and video into an mpeg stream.

Great but if you find that you need additional hardware resources,
such as offered by the multiple channels of a highend audio card
or to remove a stereo audio track, and lay down 5.1 or 7.1
audio tracks, all syncronized with the video, 
then look at my previous posting. 

Hopefully Uwe will find everything he needs on this single card, 
because once you do need to start mixing and syncronizing hardware 
from a variety of cards &&  the mobo, then thing get dicey....

ymmv && peace,


James
