have experimented some using the raspberry pi as a

results with caveats.<br class="">

Configuration:<br class="">
Raspberry Pi Slave backends running v 27.4(dated in
November)<br class="">
NFS mount to the Master backend for the mythtv
directories.<br class="">
Hauppauge USB HVR-950Q tuner(1 only ) (configured
only 1 virtual tuner so only 1 recording)<br

I did not configure the analog side of the tuner,
only the digital part.<br class="">

Using a Raspberry Pi model B and B+:<br class="">
<br class="">
Able to record Standard Definition mpg video stream.<br
class="">
When attempting to record 720p or 1080i streams,
there would consistently be TFW taking to long
errors.<br class="">
<br class="">
Using a Raspberry Pi 2 model B: (the quad core
version)<br class="">
<br class="">
Able to record Standard Definition mpg video stream<br
class="">
Able to record both 720p and 1080i streams up to
15mbps!<br class="">
<br class="">
In summary, for 1 stream and a USB TV stick The RPi
2 is a viable masterbackend with the above
conditions. I didn’t try multiple streams off the
same real channel, but I suspicion the Pi 2 would be
able to handle it.<br class="">
<br class="">
Note that I did not try analog recording as there
are no analog NTSC Over the air broadcast stations
in the area and so I didn’t even try to configure
the analog side.<br class="">

<div class="gmail_extra">Thanks for sharing this
information!<br class="">
<br class="">
</div>
<div class="gmail_extra">A few quick questions for you:<br
class="">
</div>
<div class="gmail_extra">1) Which Linux distribution are
you using?<br class="">
</div>
<div class="gmail_extra">2) I'm assuming this testing was
with a wired network (and not a USB wireless adapter)? <br
class="">
</div>
<div class="gmail_extra">3) Do you have any thoughts on
the source of the TFW errors on the Pi 1? Such as,
whether the TFW errors with the Pi 1 were related to the
CPU loading, pushing the data out across the network, or
a limitation of the USB system? (Since it kept up OK
with standard definition streams, I'm wondering if the
Pi 1 might be sufficient as a high-definition slave
backend if it recorded directly to a small local USB
hard drive, or even to its own SD card, and then did a
non-realtime NFS data transfer back to the master
backend when the tuner was idle?)<br class="">
<br class="">
<br class="">
</div>
<div class="gmail_extra">Keep us posted on how things go
if you try multiple streams or multiple tuners on the Pi
2!<br class="">

<div class="">I am using raspbian off the noobs image.</div>
<div class=""><br class="">
</div>
<div class="">You are correct, I just used wired network. I didn’t
even want to try going wireless.</div>
<div class=""><br class="">
</div>
<div class="">I didn’t even try experimenting using a local usb
drive as that wouldn’t fit my usage scenario, so are still all
good questions.</div>
<div class=""><br class="">
</div>
<div class="">I will be staying with a single USB tuner for my
needs, and Since I started using the RPi 2 configured as above,
I have had no TFW errors since starting to use it!</div>
<div class=""><br class="">
</div>
<div class="">I have no plans whatsoever to try to use an RPi of
any kind as a frontend, however, they are very insteresting as a
remote backend like I am using. The pi 2 plus the hauppauge USB
tuner are only using around 7 watts while recording!</div>
<div class=""><br class="">
</div>
<div class="">By the Way, I noticed I goofed above when I said it
was a viable master backend. I meant to say it is a viable SLAVE
backend.</div>
<div class=""><br class="">
</div>
<div class="">An experiment I might try sometime in the future is
to have an RPi as a masterbackend ONLY with no tuners(just
define a dummy recorder). No immediate plans to try that tho
yet.</div>

<div class="">Regards</div>

Has anyone managed to get mythweb running on the Pi?<br>
