>>> NVIDIA announced an AI developer board that seems to be interesting for several use cases - and maybe a MythTV Frontend?!

Looks very promising if they keep that price point.

Looks like an interesting device from a capabilities perspective, but
unless I'm missing something that form factor (everything is accessed by a
260 pin edge connector) means it's hardly plug-and-play :-)

Looks just like a Raspberry Pi to me.. USB, Ethernet and HDMI all easily accessible.

Scratch that - I just saw the developer kit :-)

You're looking at the industrial version. Scroll down for the developer
kit!

Are you sure it's the Nano?

Amazon US doesn't show it yet.  Just the NVIDIA Jetson TX1 Development
which is quiet expensive.

I think it is

...but looking more closely, it's probably an unofficial import.

Sorry - wrong link!

Careful of the third parties on Amazon. You can pay way too much. They are
snipers waiting to pick off the unsuspected shopper.

According to this
<https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/jetson-nano/>
it will be available starting in June.

I am in UK and have just ordered nano development kit, cost 95 GBP, plus
shipping,  total 101.5 GBP.
Estimated ship date is 15 April 2019, so I presume they are waiting for
stock.

From a quick play (my jetson nano development kit arrived yesterday).

Based on Ubuntu 18.04.2 LTS (Bionic) with 4.9.140-tegra aarch64 kernel.
mythtv (Client/Server) install from ubuntu repositores works, albeit the
version is an old 2:29.1+fixes.20180414.329c235-0ubuntu3

The usual fixups are required:

|sudo adduser $USER mythtv Note mythtv mysql password in
/etc/mythtv/config.xml (needed for mythtv-setup) or do: mkdir -p
$HOME/.mythtv ln -s -f /etc/mythtv/config.xml ~/.mythtv/config.xml
mythweb needs (if you have lots of channels) ||sudo mv /etc/php/7.0/apache2/conf.d/20-mythweb.ini
/etc/php/7.2/apache2/conf.d/|

I used a network tuner (VBOX 3345 DVB-S/S2 etc) on Astra 28E2 satellite everything works.

Note that all playback (SD and HD) uses ffmpeg, not the tegra GPU


NOTE do not use any mythbuntu ppa, no builds for armv8 (aarch64)

I also built current master from source, takes about an hour.
I had to install build depends manually, normally I use ansible, but this fails libcrystalhd-dev not available.

configure needs to be told location of qmake, otherwise you get
qmake: could not exec '/usr/lib/aarch64-linux-gnu/qt4/bin/qmake': No such file or directory

./configure --qmake=/usr/lib/qt5/bin/qmake

When I first saw this device, I figured that the draw of it would be
that it has nVidia graphics in a low-power, low-cost, small-form-factor
package. Sort of a modern-day ION on steroids.

I take it that this is not the case? At least with the current
software, or perhaps is it a hardware limitation?

Would this be able to do the hardware decoding and de-interlacing using
NVDEC? https://code.mythtv.org/trac/ticket/13357#no1

Possibly in 30.1?

I have tried source build of mythtv master, which should have nvdec
support, but  ./configure reports "nvdec no", even with switch --enable
nvdec.

Also a recent NVIDIA post indicates no support with ffmpeg on jetson
nano see
https://devtalk.nvidia.com/default/topic/1051471/ffmpeg-build-with-nvdec-or-cuvid-for-hw-accelerated-decoding/

Hi Mike (et al)

Old thread I know, but there may have been some progress on this:

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fmultimedia.html%23wwpID0E0JB0HA
Accelerated Decode with ffmpeg

Decode Functional Flow
<https://docs.nvidia.com/jetson/l4t/Tegra%20Linux%20Driver%20Package%20Development%20Guide/multimedia.html#wwpID0ERHA>
The NVIDIA ffmpeg package supports hardware-accelerated decode on Jetson
platforms.
An application can use accelerated decode to read video files in the
following elementary/container formats and dump them in YUV 420 format:
• H.264
• H.265
• VP8
• VP9
• MPEG2
• MPEG4

..although the FAQ seems at odds with this:

https://forums.developer.nvidia.com/t/jetson-nano-faq/82953

*Q: Is hardware acceleration enabled in ffmpeg?*
A: It is not supported in default releases. We are evaluating to support it
in future release.
A community contribution is shared. Please check
https://github.com/jocover/jetson-ffmpeg
25 <https://github.com/jocover/jetson-ffmpeg>


perhaps the github offering will work.

Anyone with a Jetson think it is worth giving it a try?

Cheers
