Oynnx Media Client

DLNA server mode

Most networked media players, including Blueray players and TV sets are fit in that mode.

Oynnx Media Client

Postby finbar » Mon Nov 07, 2011 11:02 am

Hi we have nessie workng via a Samsung TV and xbmc on a PC but we can't get it working with a Digital Stream Internet Television Box, the software inside this box is
from http://oregan.net/oregan_media_browser.php, version 4.1.5

Basically it sees the nessie server and I can browse the channels but when you select one it just shows a blank screen and says "buffering"

About the SamsungTV and XBMC (and others) - we have another where
we are collecting information regarding supported (and unsupported also)
devices: viewtopic.php?f=13&t=19

I had a look on Oregan pages but there is very little rela technical informations.

We have two way how to achive the device supported:

1. Direct cooperation with vendor's developers:
It is of course, preferable way as we can get device supported
as fast as vendor's R&D department is able to work with us.

2. Indirect, by doing some reverse analyses of network traffic.
So, for that you have to build some local lab where you
get your box working with some of DLNA server.

For such purpouse I like to recommend Serviio DLNA server
software (www.serviio.org) which is based on java and so
it works not only on Windows but also on Linux.

When you have installed Serviio and get it working with your
box, then we can move to second step - you have to log
network transmission between the box and desktop
with running Serviio.

After doing network protocol analysis we should find
what is missing (or doing differently).

Of course, we can boost such time consuming
process a bit if we get such box for testing
from you. Then we can make all that way 2 case
ourself. After success we send device back to you.

As you see, it is not so easy, but if you have really
any usecase where you need some device
supported quickly, we are able to do it ourself.

ok I shoudl have mentioned that we have the Oregan working with a Twonky Media Server.

I have put a request into Oregan asking what suport they could give us

I found the following specification in the manual for the Digital Stream Box for what is supported

Video Decoder
Video Format
Audio Decoder
Audio Format
HDMI 1.4a (24-bit), 576p, 720p, 1080i
576i, CVBS/RGB
2 x USB 2.0 Host (5V, 500mA max)
Ethernet 10/100 Mbps @ RJ-45, Wi-Fi USB adapter (Optional) @ USB
Requires two DC 1.5V AAA batteries.
12VDC @ 1.5A
0.93 (lbs)
170 x 35 x 125 (mm)
0 ~ 45°C
MPEG1, MPEG2 MP@HL, VC-1 AP@L3, H264 HP@L4
WMV MP@HL, XVID Highdef
MKV, AVI, VOB, ASF, WMV, MP4
MPEG-1/2/4 Elementary Stream (M1V, M2V, M4V)
MPEG-1/2 PS (MPG)
MPEG-2 TS (TS, TRP)
MOV (H264 only supported; quicktime/sorenson is not supported)MP4
MPEG-1 L1, L2, L3
Dolby Digital (AC3)
MPEG-2 AAC
MPEG-4 HE-AAC
OGG vorbis
WMA (lossless not supported)
MPEG audio (MP1, MP2, MP3, MPA)
AAC, M4A
AC3, WMV, WMA, OGG

I have installed and configured a Servio server and that works ok, is there some sort of tracing option that we can use to see the network traffic

Regards

I have no clue about Oynxx, but I can observe the same phenomena on my Samsung UE32C6700 TV.. at least in my case the TV contains huuuge buffer which must be filled fully before the picture is decoded and visible. It takes up to 40 sec for SDTV! During that time nothing but a small rotating circle with the 'Buffering' message is visible on the screen. Are you sure the problem is in Oynxx and not in your TV? There are many bad implementations of DLNA.. and Samsung's one is one of them, for sure. The most funny thing is, DLNA works as charm on the same TV, if the source is not LiveTV stream, but stream sent by minidlna or mediatomb from the previously recorded file on my htpc. And no, it is not only problem of Nessie, the LiveTV stream from vdr with upnp-plugin has the same (bad) properties..
So, perhaps you hit similar problem?

Good, the box has support for MPEG-2 TS (TS, TRP) and H264, so it has all what
we need to get it comaptible and working with NessieDVB.

Next step is a bit more difficult: I need to get network communication
captured (comunication between Digital Stream Box and Serviio or Twonky server).

I'm not sure how much you are familiar with network capturing. The best
tool is open-source WireShark (http://www.wireshark.org). Unfortunatelly
using the wireshark requires some basic knowledge of networking.
If you are able to capture network comunication then please do it
for one session - it is enough to get captured first 30 secs. From time
you pointed to the required TS file in DLNA client browser window.

Even more simple variant:
tcpdump -s 0 -w Record.tcp src nessie or dst nessie
replace 'nessie' by real IP address, if DNS does not contain the DNS resolution for your Nessie box. And compress and send Record.tcp afterwards :)

jata - Thanks for suggestion the buffering message stays on for evert. We have it working with Samsung and have noticed the initial delay but in this case its five minutes plus !

Attached is hopefully the trace from wireshark between the Oynx 192.168.0.4 and Servio 192.168.0.2 . I have not beeen able to use wireshark to capture traffic from a different IP is to/from nessie, so i ran it on teh pc with servio to get this trace, I have tried a a vista laptop an dxp pc but it onlu show IP traffic for that machine

The file attachmnet is too large 19 MB can I sent it to anFTP site ?

We don't have any ftp uploading service working, sorry.

But you can use any public filehosting server, like http://www.wupload.com/
or http://www.ulozto.net/

They have usually limits for free filehosting, but 19MB is small enough,
so should be ok for us :-)

Maybe just one more remark - I would really recommend you to use some compression program (zip, gzip, bzip2, xz, what-so-ever), not to produce smaller file, but to protect the content against corruption. It it always better to know that the file is/is not damaged before any attempt of analysis :) , and file corruption can happen easily on public servers. Or, alternatively, you can provide also a digest in the form of md5sum or sha1sum..
