I started thinking about how to improve
my home media center. My backend is a
powerful server with RAID so I’m covered
there. My Frontends need some work
though. It maybe my brain going crazy,
but I no longer think my Ivy Bridge i3
NUC is not up to the task. Too much
tearing at the bottom of the screen no
matter what settings I use. This started
as the kernels got updated on Ubuntu
16.04 in prep for moving to 18.04. My
guess is improving the drivers for the
new Intel chips they messed up the old
3rd Core generation drivers.
<div><br>
</div>
<div>Even my RP3 B+ has better video
performance. Since I use FireTV in
addition to Mythtv, I’m thinking of
something like the Nvidia Shield. It
can run all the apps that the FireTV
does and it plays games and runs
mythtv frontend.</div>
<div><br>

<div>At $150, I can’t buy a more
powerful PC than what I have. So I’m
thinking the Shield is right solution
moving forward without breaking the
bank.</div>

<pre>i have 2 shields i got for very low price. i agree to be able to have netflix, amazon, hbogo etc plus mythfrontend</pre>
<pre>is a big advantage. mythfrontend runs pretty well. i have a little trouble with h264 using mediacodec so i use ffmpeg</pre>
<pre>codec for everything. also for me only ffmpeg codec allows subtitles. playback is acceptable. not as good as on my backend, </pre>
<pre>a ryzen 7 with nvidia 750 ti. you could also try to build from master and check out the vaapi 2 and see if that improves </pre>
<pre>the nuc's before you take the plunge. overall i'm quite happy with the shield on a 4k tv and thanks to the great </pre>
<pre>work by peter bennet now having mythfrontend makes a really versatile solution for me.</pre>

<p>The advances of small multi-core CPUs
with built-in GPU has been great since I
retired from the industry. I know that a
PC that you spend $400 for will do the
job. Also an old PC with a good Nvidia
graphics card with do the job. For me
form factor is also a big issue. That's
why I spent a lot of time debugging
performance on the 3rd gen Core i3 NUC.
But that performance is going down not up.</p>
<p>The RP3 B+ is quite good on Kodi but
still lacking on mythfrontend. Neither can
do SlingTV, Prime Video etc.</p>
<p>So if the developers are spending their
time on Nvidia Shield then that may be the
direction I should head. The hardware
specs on the Shield are impressive and the
price is nice. I am sticking with v29 on
the backend because it's stable. I know
the pre30 mythfrontend works on my Macbook
with the v29 backend, but had missing
libraries on the RP3 with Raspbian. So I
can't see if any improvements have
happened on the RP3. <br>
</p>
<p>From monitoring the mailing list I see
there are a number of people with the
Shield. My use case for the Shield would
be Mythfrontend displaying recorded MPG2
files from OTA tuners. I use the HDHR
Quatro and Connect devices. <br>

<div>i run the mythfrontend on a shield and
also use the hdhomerun quattro as well as
hdpvr. the files play without stutter and
any frontend features i use all work. i do
have to use a cheap usb wireless backlit
keyboard to do edits and other functions as
the remote is limited (at least for me).
that was another 10 dollars. i can't answer
about question on dvb streams but i think if
u.s. mpeg2 hd plays those would also play. i
have mpeg2 files that go over 6gigs/hour.
only issue i had was on hdpvr content or
other iptv content in h265 that i had to
change codec. but they play. </div>

So if the MPEG2 videos from the HDHR Quatro are good
on the Shield then I may make the jump to it. I also
use the USB wireless keyboard for editing and setup.</div>

<p><br>
</p>
<p>So now for the stupid question. When you say de-interlacing
was excellent, what do you mean? On what content does that
matter? I only watch HDTV recordings from a HDHR Quatro via
OTA antenna. It's usually 720P or 1080i depending on channel
and program. Both of those I consider HDTV.<br>

<div>i don't know firestick 4k, but i had a
cheap box with the s905x arm, same as mibox,
and it was pretty bad on mythfrontend.
shield a world of difference on mythfrontend
and everything else. i did put libreelec on
the cheap box and kodi worked really well
fwiw. hope that answers some of your
questions. </div>

<pre>deinterlacing is necessary on anything like 1080i content not 720p. in terms of over the air, it can be interlaced</pre>
<pre>or not depending on channel. in terms of hdpvr it is all interlaced as far as i know so it comes into play.</pre>
<pre>
</pre>
<pre>i have my settings to ffmpeg to decode, and linear blend 2x as deinterlacer. ymmv . i used the ffmpeg because i am</pre>
<pre>old, and from time to time i use subtitles, and i could not get it to work with the mediacodec default decoder.</pre>
<pre>you would probably be best to just leave defaults of mediacodec and you will get a good result</pre>

<p>Well I ordered one from Amazon and should have it on Friday. It's
the one with the new game controller and TV remote. If this works
then I can eliminate the NUC, the FireTV stick, and not use the
Samsung 4k TV built-in streamer, which is worse than FireTV stick
on Sling and Prime Video.</p>
