[linux-dvb] Questions on v4l-dvb driver instructions

[linux-dvb] Questions on v4l-dvb driver instructions

[Jonathan Coles]

Your instructions at http://linuxtv.org/repo/ for obtaining v4l-dvb say 
to execute:

hg clone http://linuxtv.org/hg/v4l-dvb

But this returns

abort: error: Name or service not known

Perhaps there is a mistake in the instructions.

It seems this checkout step is not really required, as you can download 
the tarball from a link on the page at the URL.

I also find it confusing that you mention dvb-apps, but don't talk about 
compiling it. Is it needed? Optional? An alternative?

Are there additional steps not presented here? I was unable to get my 
Hauppage HVR-950 to work on Ubuntu 8.04. Does this package support that 
device?

copy and pasting that line here works fine:

% hg clone http://linuxtv.org/hg/v4l-dvb
destination directory: v4l-dvb
requesting all changes
adding changesets
...etc

One advantage of using mercurial over the tarball is the ability to
run `hg pull` and `hg update` rather than re download the entire set.

dvb-apps AFAIK are optional. I have not yet needed them in normal
operation of a tuner card.

Do you have the firmware for the device as well as the driver?

On the mythtv-users list there was a success story using one of these
tuners. It details how they got it working before going into issues
using two of them:
http://www.gossamer-threads.com/lists/mythtv/users/349205?search_string=HVR-950;#349205
He was using the mcentral repository, and Edgy but the steps are
otherwise the same.

Hope this helps,
cheers,
Owen.

Perhaps I have some other misconfiguration in my system. With the wget 
command I must use the --no-proxy option. Otherwise, I get "Error 
parsing proxy URL http://:8080/: Invalid host name." Very strange that 
port 8080 is assumed when the standard port is 80.

I couldn't find an equivalent no-proxy option for hg.

Thanks.

Read this, it will probably help :)

I already have the man page for hg and hgrc. But, admittedly, I had only 
looked the one for hg.

Assuming the problem was proxy related, as with wget, I added a 
[http_proxy] section, with "no=linuxtv.org". That worked! Unfortunately, 
"no=*" does not work, so every Mercurial host I ever want to access will 
have to be added to the file.

I don't understand why I would use a proxy for downloads. If this is on 
one's own machine, what security is gained?

Overall, the Mercurial issues are just an unnecessary complication, and 
my real problem with v4l-dvb for the HVR-950 is probably something to do 
with loading firmware or kernel modules. Linux has come a long way in 
the five years or so that I have been using it. But, some things, like 
using an off-the-shelf USB device, can still prove impossibly complex 
for those of us who are not hard-core computer geeks.

Thanks for your help.

That is indeed strange, as Ubuntu does not ship with any proxy support
enabled by default.

The HVR-950 works in Ubuntu 8.04 (that's what I wrote it under) but be
forewarned that Ubuntu screwed up their kernel build process in 8.04
so that the analog audio driver doesn't build from source.  If you're
planning on using the device for ATSC then you are fine, but if you're
doing analog audio then you would need to rebuild the kernel from
source (which is a real pain).

I can certainly appreciate your frustration regarding this stuff
"working off the shelf".  It was that exact frustration with the
HVR-950 support that got me involved in the project in the first
place.  If it's any consolation, since support was merged into the
kernel it now works in the stock Fedora 9 and it will work in the
out-of-the-box Ubuntu 8.10 when it comes out.  All you will have to do
is stick the firmware file into /lib/firmware.

No idea, I don't use proxies to be honest. I did google quickly and 
found that I thought you needed.

It is getting better but some drivers / products are still confusing for 
end users. Sorry this didn't work out well for you.
