files stuttering bad

[mikeg]

Computer is AMD PhenomII 955 quad core 16gb ram hard wired network my switches that connect my homes computers and tv's are all 10/100/1000. I have 2 WD Live boxes that dont stutter at all with movies playing on both and purchased Mezzmo so as to not have to buy another WD Live Box and with nothing playing the movie stutters on my Bravia KDL-55NX810 please help I have 4 other TV's.

Hi mikeg,

When you play a movie on your Sony Bravia TV and it starts to stutter, go back to Mezzmo on your PC and check the Transcoding tab. Check if your video is listed there and is marked red. If it is, then transcoding on-the-fly is not fast enough for real time playback. One solution is to pre-transcode the video before playing it (see http://forum.conceiva.com/showthread...nscoding-Files).

Let us know the device profile that is assigned to your TV in Mezzmo. Go to the Media Devices dialog to see this.

Also, post the FFmpeg information for the video that stuttered. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.

I checked the transcoding tab when i was creating the log file you looked at and although it was stuttering it was NOT marked red?

Device profile is Sony Bravia KDL (2011 models)

Understand. Try pre-transcoding the video. After it completes transcoding, try playing it and see if it plays smoothly.

[mikeg]

Ok Paul so I upgraded processor and motherboard (it was due for an upgrade) I now have an 8 core 3.5 ghz Amd 8320 unlocked black edition and it still is hit and miss with some movies, I have one that transcoded at 850 fps and the playback has a bunch of blocks in it but when I play it on the same tv with my WD Live no problems clear as a bell? I looked to see CPU usage and it was only around 10%?

[Paul]

Hi mikeg,

The 850 fps tells us that Mezzmo was remuxing the video. Just to explain - a video file (e.g. movie.MKV) is made of the video file container (e.g. MKV matroska) and inside the video file container are various video channels (e.g. H264, MPEG-2, MPEG-4), audio channels (e.g. DTS, AC3, AAC) and subtitle channels (SRT, SUB, ASS). When Mezzmo has to transcode a video to another format, it will prefer to copy (or remux) the video or audio channels into the new file container since this is very fast (as compared to converting to another format). So, in your case, your Sony TV cannot play MKV files and Mezzmo remuxed the video and audio channels into a compatible file container, such as MPEG-TS. The fact that your WD TV Live can play the video well but your Sony TV cannot shows that they both have different firmware that read and play videos differently. For the video that is 'blocky', try pre-transcoding it - but make sure you select the 'Force full transcode' checkbox to stop any remuxing. For details on pre-transcoding, see http://forum.conceiva.com/showthread...nscoding-Files.

[mikeg]

Understood, I will try that. Next question my TV is a 2011 and with the KDL 2011 profile no Avi files show up in the list on TV they are in the library.

[mikeg]

ok I tried that and it failed right away this is what it spit out.

Changed profile to kdl 2010, I will see what happens at least it is doing the full force transcode.

OK - let us know how you go.
