USB video input card
I'm considering to buy Acer Revo or similar unit for use with MythTV. It
is interesting that it is actually cheaper to buy a pre-built one rather
than build an NVIDIA OIN based HTPC yourself. However, all these nettops
are missing some crucial (for me) feature - video input. The only option
seems to be to add a USB tuner card (I don't need the tuner, but I could
not find video input cards without one).



Anyway, my question is - are modern NVIDIA ION and Atom based nettops
such as Acer Revo and Asus EEE PC powerful enough to support video
capture via USB along with playback, i.e. timeshifting ?

I have a dual core Revo (R3610) and it seems fine recording 1 DVB
stream from a USB dual tuner whilst watching live TV.

I have 2 drives, an OS+mySQL drive, and a larger ESATA recordings
drive which helps split IO. I also have 2Gb of memory, but that is
not essential to myth, as I plan to use this host for other server
like things as it is on all the time (home Samba server, webserver)

Do you have any idea what is the CPU load in such scenario ? R3610 is
not widely available yet, so I'm thinking of getting the older AR1600
model

Where are you - there are loads available, and the R3610 is cheaper
than the other models (in the UK at least) for some odd reasons.

Load is not a great indicator of work, as it is just a running average
of the run queue - which on a Host that appears as 4 CPUs this is not
great) indication of busyness.

Just a short test recording one DVB program;

iostat 5 -x (skipp 1st few lines);

uptime
16:33:30 up 1:31, 3 users, load average: 0.32, 0.49, 0.56

Although CPU usage is minimal (93.76% idle) the load is a around 0.56
(however on an SMP host I would divide this by no of CPUs to get a
clearer "load") which is equal more like "0.14" (0.56/4) which is
still above CPU util.

I'll do more test later;

- Record 1 stream, watch 1 recording
- Record 1 stream, watch live TV
- Record 2 streams, watch 1 recording

But in Summary on my dual core host I see minimal CPU use most of the
time, but I do see "Load"

I'll do more test later;

- Record 1 stream, watch 1 recording
- Record 1 stream, watch live TV
- Record 2 streams, watch 1 recording

But in Summary on my dual core host I see minimal CPU use most of the
time, but I do see "Load"

Wow, thanks for the info, it is very helpful!

I'm in Israel and Acer Revo is not sold here at all, but I Will be
travelling soon to US and UK and intend to buy one there. BTW, I just
checked a couple of UK online stores and there appears to be some sort
of confusion - many shops in UK offer a so called RS3600 which judging
by the specs is more similar to 1600 - it is based on Atom 230 CPU and
not 330. Take a look
http://www.amazon.co.uk/s/ref=nb_ss?url=search-alias%3Daps&field-keyword
s=acer+revo&x=0&y=0

Which one do you have ? And while we are on the subject, were would you
recommend to buy one ? I'm talking about a brick-and-mortar store in
London.

Thanks.

Yes - many stores list the dual core under R3600 when it is actually an R3610;

I have an R3610;

http://www.amazon.co.uk/Acer-Aspire-Desktop-RAM1024MB-HD160GB/dp/B002WCBBDO/ref=sr_1_2?ie=UTF8&s=electronics&qid=1258914616&sr=8-2

Same reseller £10 cheaper;

http://www.ballicom.co.uk/laptops/sub-notebook/acer-revo-3610-atom-330-dual-core-1gb-160gb-linux.p466112.html

Lots of myth UK users have brought from Ballicom.

The UK SKU, 92.NVDYZ.UI0, has a UK Keyboard, and uk plug, although the
PSU is 110-240v, you will just need shaver style dual

I am not sure of UK B&M stores, I get all my stuff online. Amazon and
I am sure Ballicom would deliver to a Hotel! I have done this in the
past when in the US. I am sure somewhere does it but I have no idea
where. I would inquire with Ballicom online. Do you have an address
in the UK you can deliver to?

Greg

Re: USB video input card [In reply to]
More Revo stats, just to keep you all entertained. Not very scentific
as I have only taken one snapshot per test for 5 secs.

Anyway;

ordered one last week and followed their instructions on how to get the item
delivered to an address separate from the invoice address. Basically, their
website says they won't do this automatically but if you follow up your
order with an email they will contact you to arrange this. I followed up
immediately after the order with an email and also put these requirements on
the order notes for good measure.

Anyway, Ballicom didn't get back to me to arrange delivery, didn't answer my
mails/phone calls and the item was dispatched to my invoice address. In the
end had to waste an hour on saturday driving to the courier's delivery depot
to collect the thing personally.

On the plus side, the item was correct: Dual core 3610 and the price was
excellent. So if you don't mind the item being delivered to your home
address things might be ok.

Lots of myth UK users have brought from Ballicom.

I'm one of them and I couldn't say I recommend them as a retailer. I ordered one last week and followed their instructions on how to get the item delivered to an address separate from the invoice address. Basically, their website says they won't do this automatically but if you follow up your order with an email they will contact you to arrange this. I followed up immediately after the order with an email and also put these requirements on the order notes for good measure.



Anyway, Ballicom didn't get back to me to arrange delivery, didn't answer my mails/phone calls and the item was dispatched to my invoice address. In the end had to waste an hour on saturday driving to the courier's delivery depot to collect the thing personally.



On the plus side, the item was correct: Dual core 3610 and the price was excellent. So if you don't mind the item being delivered to your home address things might be ok.



As my home address is not in the UK I guess the chances of that are slim. On the other hand, I cannot afford not having it delivered on time and to the specified address. Strangely enough, I cannot find this unit in the US

Re: USB video input card [In reply to]
And finally to bore you all some power stats;

For revo host only (with Esata disk);
Recording 1 or 2 Channels - 24W (32W)
Recording 1 or 2 Channels, whilst watching a recording (or 1 channel
and live TV); 28W (36W)
Idle (mythfrontend on main menu); 24W (32W)

So oddly watching something adds 4W, which is some CPU and mostly GPU
I assume (as IO is from an external Esata drive).

This compares to 64W (stable) for my Via SP13000, 2xNova-T PCI cards,
1x750PATA, 2x400SATA drives with 1GB ram.

System;

Revo R3610 (Dual core) with 160GB OS drive (with MySQL)
2 GB Ram (extra Dimm)
Huappauge Nova-TD Dual Tuner Stick (Model 1175)

Mythbuntu 9.10 x64, FEBE with Avenard (VDPAU)

Data drive (Not included in about power stats)
Esata Enclosure with a a HD154UI Samsung 1.5Tb 5W drive; the enclosure
pulls 8W on a separate plug
