Mezzmo performance problems?

[jsoadmin]

I cant stream 1080p MKV-files neither to my Samsung or LG with Mezzmo over my WLAN (802.11n / 5GHz) without disturbances. 720p works alright. However with TVMobilii even 1080p works without any delays or temporary hangs etc. How come? Same file, same equipment, the only thing that differs is Mezzmo/TVMobilii....

Can you please check the transcoding pane in Mezzmo while playing that file and see if the file is being transcoded? Which device profiles are you using for your devices?

[jsoadmin]

Yes, it actually was transcoding. I have two versions of the same movie, one 720p and one 1080p. The 720p version did not trigger a transcoding but the 1080p version did.

On my LG BD670N blueray I use the LG Blueray(PCM) profile and on my Samsung BDC8200 I use the Samsung BDP profile.

After checking the box to never transcode (in the trancoder setting pane) even the 1020p version runs smooth on both my devices.

Trancoding seems very CPU consuming, got a 6 CPU AMD running at 3,4 GHZ and still I only get approx 18 FPS in trancoding speed on the 10080p movie....

[Paul]

Yes, full transcoding is very CPU-intensive, but in most cases you shouldn't need that.

Can you please right-click on that file in Mezzmo and post the output of the "Get FFmpeg Information" command here, so that I could check why it triggers full transcoding?

Thank you for the file info.

That file should've been passed through natively using both the "Samsung BDP" and "LG BluRay (LPCM)" device profiles, so perhaps there's something in your configuration that causes it to be transcoded. Can you please tell me if you modified any setting in the device properties?

To know for sure, please enable logging (see this thread: http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) then try playing that file on one of your devices and once transcoding starts, stop the server and send in the logs to support.
