Hi, Folks
I will attach a patch for the Medion MD7134 Hybrid Tv card.
The status is:
- DVB-T works
- Analog TV works
- OSS sound streaming works
- FM Radio works but with some limitations
- Sensitivity could be improved
- There is no status readout, neither level, nor stereo
For the sound streaming, i currently use sox:
sox -c 2 -s -w -r 32000 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp
It is running on kernel 2.6.11, maybe it works for older kernels as
well after some Makefile editing.
The patch is built against Gerd Knorrs latest video4linux snapshot,
you will find it at:
http://dl.bytesex.org/cvs-snapshots/video4linux-20050426-090128.tar.gz
Since it is a quite big amount of code, i split the patch into 3 parts:
Part 1 is an extended version of the tda1004x driver which was not
yet in the video4linux distribution. Besides some cleanup, i made the
following changes
- It optionally works with a 16MHz crystal insteal of 4MHz
- It the card has a firmware eeprom, the DVP can boot from this
- It is more relaxed with the firmware revision
- It has config options for different IF frequencies and AGC configurations
I had to extend the ths1004x_config data structure to make this work.
Basically this breaks the compatibility to existing drivers. But if the
new entries are left 0, you will get the old behaviour.
Thanks to:
Niels, Niels and Wolfgang for reviewing and testing the driver
Andrew, Gerd and all the others who provided the base for this code.
Please report success or problems.
Have fun
Hartmut Hackmann
