Another stuttering Stream problem..

Postby Moxx » Mon Dec 19, 2011 9:54 pm

Hi there,
i am experiencing pixelled image and sometimes no sounds for a sec or so every 10-30secs when watching HD channels.
When using VLC Player with direct Channel-IPs there is no Problem.
My basic setup is a WHS 2011 Server with DVBLink on it, an a htpc, connected by dLAN (Lan-over-Powerline) with ~130mbit ->MediaCenter/Dvblink = stuttering image, VLC Player good.
I tried to solve the problem by connecting the htpc with a patch cable, (gigabit), same problem.
Third test was MediaCenter/DVBLink on a third PC, connected with GigabitLan, same problem.

What i tried:
1.) mentioned above
2.) setting priority of the server to real-time
3.) setting different streaming port (change 8080 to 39800)
4.) Client-Priority is set to 256 i think, should my ok?
5.) Trying not to get crazy :)

Here is a link to a testvideo stream where you see the problem about 2 times (just without the pixelled image problem, that just appears on the livestream): https://rapidshare.com/files/4058115739/video_url1.ts

What else can i try?
so long,
mo

The Playlist reads all like "rtp://@233.51.128.19:1234" and so on! -> So rtsp
(And by the way, thanks for taking you time to help:) )

Set log level on Server Setting page to Info and try channel preview http://www.dvblogic.com/wiki/index.php? ... t_channels on Channel Selection page.
Attach dvblink_server.log

You may try using TCP streaming instead of default UDP streaming:
- Stop dvblink server windows service
- open the dvblink_configuration.xml file and change the following line in `nb_server` section to:
<use_tcp_streaming>1</use_tcp_streaming>
As an example:
Code: Select all
<sinks>
...
<nb_server>
<sink_control>nb_server.dll</sink_control>
<type>1</type>
<use_tcp_streaming>1</use_tcp_streaming>
</nb_server>
...
</sinks>

- Start dvblink server Windows service

Update: When using MediaPortal Client (on Win7PC) to connect to MediaPortalServer (WHS 2011), which itself gets its signal from the DVBLink Signal(WHS 2011,too) HD-Channels run like charm..
So i assume it's a Problem with WindowsMediaCenter.. :/

i get some info regarding ati and artifacts from google:

artifacts still there with 11.11 WHQL
catalyst 11.5 is ok but DXVA dont work ati hd2600 toshiba.

10.7 is ok

10.6 is ok

9.8 is ok.

10.4 is ok

These are reports from people ati diferents ati cards, and hdtv artifacts in win7 mce.

For me, 10.6, 9.8 is ok, with wireless atheros 54mbs and unistream, buffer to medium, priority realtime in v3.2. From time to time i get artifacts for 1 second or so.
In v4.1, sometimes hd artifacts appear, but they are quite rare, but i get playready problem all the time.
with dlink wireless 300mbs, i get artifacts.
If you install an " bad" driver, you get artifacts on both SD and HD, in mediacenter or mediaplayer.
ALso i try to use 10.6 driver with 11.12 catalyst control center, amd codec and avivo from 11.12 and is working also.
