I have a card not supported by the DVB drivers in 5.5, but there is a driver in the latest V4L-DVB package. I downloaded it, and tried to compile after installing the kernel source. Here are the last few lines of the make log.

Code:
  CC [M]  /storage/v4l-dvb/v4l-dvb-0ebffe1cc136/v4l/saa7146_core.o

Can anyone help me figure out what is keeping it from compiling? My linux-fu is sketchy at best, but I'm not afraid to ask.

Thanks.

Looks like a problem was introduced into the development tree a few days ago. I have not looked into why it is failing, but I happened to checkout revision 8250 last week and it compiles OK.

You can checkout this particular version as follows.
Code:
 hg clone -r 8250 http://linuxtv.org/hg/v4l-dvb

I haven't done any real testing with this revision. In the past using the v4l-dvb development tree has had incompatibilities with ivtv based cards. I am not sure of the current position though.

Edit: Added Caveat

Thanks babblefish!

I was just about to build a KM box to our cabin, and I have a USB anysee tuner lying around. I compiled the v4l drivers three days ago, but my trusty old 40 GB disk blew. And now that I tried it - wont compile. Almost posted here if anyone has any hints to fix it, and obviously someone did.

Once again.

What a magnificient community!

Well, I got it to compile, but the system won't recognize any channels on the DVB. More work...

With Anysee E30+ there were some problems also.

I compiled the v4l drivers, and they worked like a charm. Scan went through nicely. I even installed Kaffeine, because it's said to have best chnanel scan features and I got the TV visible in a couple of minutes. I anticipated more problems, because I had the device attached to a prodige USB -card. My poor K7T Turbo only has USB 1.1 built in.

There are some pauses in the image, but it is most likely because I'm using the telescope antenna. Once I get a proper signal, I'll post a howto for Anysee.

Ok, so that went well. However, on MythTV side there were problems. I selected the "v4l-device" from cards-section in mythtv-setup. Tried everything. Put /dev/dvb/adapter0/frontend0 as a device and the same as VBI device. Nothing. No matter what I did.

Then, suddenly, I changed to the "normal" dvb-card setup, and it found some Zarlink ZL10353 based device in PCI 0. Scanned channels and everything seems to be working.

Ok - it is not so easy... Now I've tried it with indoors antenna, and ran into some problems. I'm using the "DVB-DTV -card(v3.x)" in mythtv-setup, and using the default values, except that multirec is set to 1. The device (Anysee E30+) is shown as Zarlink ZL10353 DVB-T device. Tied it to EIT -only video source.

I can scan the channels, and it finds the correct ones. Te signal is now between 75% and 80%. That should be plenty, and Kaffeine can display the channels without any problems.

But on MythTV there is a problem: when ever I try to watch TV, there's no image, and the info display shows "Signal 19% | BError 0 | (l__) No lock" And of course after a couple of seconds I get "The channel should have tuned already" -message.

I wonder what does the BError 0 mean?

Another approach would be to use the device as v4l-card. If I try the v4l -device in mythtv-setup, I guess I should use /dev/dvb/adapter0/dvr0 as a video device, but it can't be opened. Tried giving it permissions, chowning it to mythtv user but nothing worked.
With my limited skills I checked the logs, and found no reason. dmesg reports nothing exceptional.

Any help would be appreciated.

The head of the v4l-dvb development tree now compiles again. I have successfully compiled revision 8420.
