Hi,
It seems all MKVs stutter on my 2 year old 32" bravia. I have serviio setup on a couple of different pcs, one a 2008 server with celeron 2.4 cpu, and another Windows 7 pc with a quad core q6600 cpu,using DLNA over 200 mb ethernet home plugs anything I can do to stop the stuttering ? It seems to affect all MKV files ...

I have done some more testing .. I understand the highest birate the bravia can handle is around 20 mbps ? I used bitrate viewer to check the bitrate on an mkv and it was averaging at 6160 kbps which is 6.16 mbps so should be able to handle that ?
Are there any specific renderer settings or anyother settings I could change that might help ?
Cheers

Could you provide informations about your mkv files, with MediaInfo result and "ffmpeg -i " (see signature links) ?
What is your model number?
Do you have automatic library update enabled?

can you try it via a direct LAN connection rather than the plug?

Are you talking full on stuttering, or some very slight jerkiness during smooth panning shots? I notice that my 2009 Bravia (on the MKVs it can play without transcoding) converts the frame rate from 24fps to 60fps, but it does so rather badly compared to the Sony BDP.

It will play fine for a few seconds then stutters every few seconds. Its the same with all MKVs. Will try and get the info you need. Ihaev tried with a direct lan connection and get the same issue I think, will double check, thanks.

Video Codec is probably the problem: AVC High Level 5.1 (CABAC/16 RefFrames) is too high: For sony devices it seems that 4.1 is the max.
Could you rename the file, force library refresh and check the log file?
->This file must be detected with an high level profile.
Could you also check the log file when you start this movie?
->must be transcode into mpeg2video with ffmpeg.

Yep, but in that case the file is transcoded, which I'm assuming the Celeron might not cope.

ok, will test with the quad core q6600 and see what results I get.. Starting to think it might be easier to just buy a MKV player .. would just be nice if I could watch HD video through DLNA ...

Is this still/always true?
I noticed that sometimes serviio can not detect the h264 profile and therefore after the file is not transcoded.
Marculos, to be sure, could you check the log file to see if file is delivered in native format or transcoded with mpeg2video.

heres the log when the file is added. Two useful things for log files, Trace32 which comes with sccm toolkit is excellent for viewing log files as it auto refreshes, 2 - a program called VIM is excellent for opening huge log files without crashing.

we have some success ! It seems MKVs with AVC High Level 4.1 codec now (though need some more testing to be sure) play ok on the quad core pc. What I cant find is entries in the serviio.log when a video is playing, not sure why. Anyway I guess I could convert AVC 5.1 to 4.1 so that the mkvs can be played ? Many thanks for everyones help.

As you've probably noticed, Serviio's logs segment as they grow, with the latest one always being called
serviio.log, so they're never too big. Rather than posting screenshots it's far easier to simply open them in Notepad and paste the relevant bits here inside [code] tags so they are collapsed until clicked on, for better forum readability.
