Card features

  • PCI interface
  • SAA7134 chipset
  • RDS-Tuner Chip SAA6588 chipset
  • MPEG-Encoder Chip SAA6752HS
  • FM, TV, Composite, S-Video and Audio inputs (outside)
  • Two conectors (one is Audio out) (inside)

How to make it work

It was detected automatically as card=24.

The sound doesn't work from internal Mixer (at the moment - should work according to Video4Linux Mailing List). At the moment I use the Audio-out conector inside. If you hold the slot cover at the left and the PCI connector at the lower side, the audio out connector is the lower one. The 4 pins from the white MIDI-connector are from left to right: left-channel / ground / right-channel / ground. This one I connect to an audio input (Aux) of my sound card (SoundBlaster Live! 5.1). If I switch the input to this channel, the sound works fine.

The MPEG-Encoder works, as long as saa7134-empress and saa6752hs kernel modules are loaded. The MPEG TS stream is available at /dev/video1. The default parameters are:

Resolution: 720x576, aspect ratio 4:3
Video: MPEG2 TS 4000 kbps VBR (max 6000 kpbs) PID: 260
Audio: MPEG2 L2 audio 265 kbps PID: 256

In August 2008 the driver has been fixed to properly use V4L2 MPEG API (extended controls). According to Video4Linux Mailing List using a recent v4l-dvb repository, it's possible to change most of the encoder properties using v4l2-ctl.

There is some information, that mencoder supports V4L2 MPEG API, VLC has some support through pvr access module (i.e. it's possible to set one of the following resolutions: 720x576, 480x576, 352x576, 352x288).

Kernel

The card runs ok on kernel 2.6.11.4 and up.
