Problem getting sensible video out of Hauppauge HVR-1100 composite

[Neil Bird]

   I'm in the UK (PAL), & have a Hauppauge HVR-1100 on Scientific Linux6:

2.6.32-358.18.1.el6.i686
libv4l-0.6.3-2.el6.i686
v4l-utils-0.9.0.git5f24b816-2.el6.i686
ivtv-firmware-20080701-20.2.noarch

Hauppauge WinTV-HVR1120 DVB-T/Hybrid [card=156,autodetected]
input: saa7134 IR (Hauppauge WinTV-HVR as 
/devices/pci0000:00/0000:00:14.4/0000:05:07.0/rc/rc1/input13
rc1: saa7134 IR (Hauppauge WinTV-HVR as 
/devices/pci0000:00/0000:00:14.4/0000:05:07.0/rc/rc1
input: MCE IR Keyboard/Mouse (saa7134) as /devices/virtual/input/input14


   (I think that's the relevant firmware)


   I set everything I know of up OK, but when I access /dev/video0 I get 
a garbled pink MPEG file (cat to a file, then mplayer to test).  The 
DVB-T aspect of is works fine (tested using vlc).

   The only logger error I can see that might related is:

kernel: tda18271_write_regs: [2-0060|M] ERROR: idx = 0x25, len = 1, 
i2c_transfer returned: -5
kernel: tda18271_channel_configuration: [2-0060|M] error -5 on line 119
kernel: tda18271_set_analog_params: [2-0060|M] error -5 on line 1050

   .. but I think that may be something else (I have another DVB card 
plugged in).


   I have:

$ v4l2-ctl -I
Video input : 1 (Composite1: ok)

   .. so I think it can see something.  If I unplug the [known working] 
composite feed I get:

$ v4l2-ctl -I
Video input : 1 (Composite1: no hsync lock., no sync lock)


   Lastly:

$ v4l2-ctl --all

   I had done a 'v4l2-ctl --set-fmt-video=width=720,height=576' 
previously as that's what I've done on my old Hauppauge PVR-350, but 
don't recall why it was necessary, I was just trying anything I could. 
I'd also done 'v4l2-ctl --set-standard pal'.

It doesn't have a MPEG hardware compressor like the 350, you are
reading raw pixel data (160Mbps) from the device node.

Use an application that renders raw video data, such as TVTime.

   Ah, OK, thanks, I managed to miss that.

   I can get a picture out of it by using vlc's open-device.  So it's 
working.

   But, flip me, it's spewing 800 MB+ for a minute's worth of video. 
That'd be ~48GB for an hour's TV (the intention is to use this for a 
MythTV PVR).

   Am I likely to be able to do anything about that?  Even with 
post-transcoding that's going to be an excessive amount of filing to 
deal with :-(

The device doesn't have an MPEG encoder - you're getting raw
uncompressed video.  You would either have to buy a different device
that has an encoder or do software encoding in real-time to MPEG2 or
H.264 if your goal is to store the video.

Generally not a good idea to do what you're doing. Generally a good
idea to use a card with hardware compression features for a myth DVR.

   Yeah;  I'd spent so long trying to find a card with an s-video input 
that was likely to work without too much grief that I plain forgot that 
they don't all have the built-in encoder and didn't check it.

   S-video requirements are a dying breed, unfortunately.

   Don't suppose you know of any?  I see the Hauppauge HVR-2200 does, 
but it looks like the drivers for that are a bit too “fresh” for me to 
be able to risk another blind purchase (and may require kernel 3.2+, 
where I'm on SL6 with 2.6.~32).

I'd backport the HVR2200 driver into 2.6.32 (it may already exist with
analog features in .32 btw) and go with a 2200.

   Hah, not my first choice :)
