Hello there,
I am new to the video streaming in general as well as UMS.

My problem is that some videos cannot be played correctly on my PS3. In other cases there are no problems at all, even with 1080p videos.

• In my first test the was no playback, neither audio nor video. Please see the attached archive test1_ums_dbg.zip.
• As second test there was audio playback but the video playback was heavily distorted. I don't know what the correct term is Please see test2_ums_dbg.zip for that case.

I assume that the problem might be caused by a wrong configured codec?

Finally some general information:

• Network: Develo dLAN 650+
• Windows 7 x64
• UMS 3.5.0
• K-Lite_Codec_Pack_1040_Full >> hardware acceleration for nvidia graphics card chosen
• Codec configuration is attached as log >>
• klcp_codec_log.txt
• VLC installed
• Speaker setup 2.0

Do you have any idea what causes these problems?

Any help is very much appreciated. Thanks in advance!

Anyone?

Are the PS3 and UMS server connected via ethernet cable or wifi?

Hello Wolfgan,
UMS server and PS3 are connected via ethernet cable via the develo dLAN 650+. In between there is a Gigabit-LAN router.
Most other movies and series I can watch without any problems. That's why I thought it might be misconfiguration codec.

Check the CPU usage on your server when the stuttering happens, maybe the transcoding process is chocking your machine (logs indicate transcoding happening, just search the logs for tsmuxer and mencoder entries)

Thanks for the detailed report. By default, UMS doesn't use codecs.
The reason for the second file having distortions may be due to it being a remux - its bitrate may be too high for the PS3 to support over network instead of disc. Just a guess.
When you have a file that doesn't work you can always go into the #TRANSCODE# folder and select a different engine for that file, usually if MEncoder fails then FFmpeg will succeed and vice versa.

Thank you for the information I will have a look at it and get back to you later.

Selecting a different engine did the trick
The topic can be solved/closed I think. Thank you!
