Hauppauge WinTV Nova S Plus Composite IN

Hauppauge WinTV Nova S Plus Composite IN

[shacky]

Hi.

I'm trying to record some video using the composite input of the
Hauppauge WinTV Nova S Plus, which is indicated as supported on
http://linuxtv.org/wiki/index.php/DVB-S_PCI_Cards.

I tried playing video from the input with VLC and mplayer, but I'm
getting a black screen.

I checked all cables and they work good, I checked viewing the output
with a regular TV and I can see the image.

I have the devide /dev/video0, as following in dmesg:
[    6.650431] cx88[0]/0: registered device video0 [v4l2]

This is the complete output:

I tried to do this recently too and found it very non obvious how to select the correct video and audio inputs. For a few days I thought the driver was not working but I ended up using mencoder successfully with the following line:

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf   -vf scale=720:576,harddup -srate 48000 -af lavcresample=48000   -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=8000:keyint=15:vstrict=0:acodec=ac3:abitrate=192:aspect=4/3 -ofps 25   -o johntest1.mpg tv:// -tv input=1:norm=PAL-BG:amode=1:alsa=1:adevice=hw.2,0:forceaudio:immediatemode=0:volume=100

I was using Ubuntu 12.04 64bit, 3.2.0 kernel.

Hopefully this will give you the clues to get mplayer to work, I was never able to get VLC to switch to the correct audio input although video worked ok.

Thank you very much Andre! It works!

I only have a problem with the audio quality: it is distorted
especially on the high frequencies.
Do you have any idea?

Only to play with the volume= parameter, I'm sure you tried that, maybe there are some audio controls but I haven't found them. The VCR tapes I have to transfer have very quiet and muffled audio, old home videos so I thought the audio sounded ok.

I will be doing some recordings with this in a week or so after a business trip so maybe I'll find out something more then.

There must be someone on this list who knows a great deal more about the mixers and filters available.

Thank you very much.
I tried with the "volume=" parameter, but it seems to be useless.

I also see that I cannot use alsamixer with the capture device of the
audio card of the Nova-S, which is managed by the cx88-alsa module. I
cannot set any volume level, so I think it works at 100% every time,
and I cannot find any useful information on how to add the mixer
functionality to cx88-alsa module...
