Random Stutter while streaming

[Paul]

Hi James,

Since you have transcoding turned off, then Mezzmo is simply streaming your original files directly to your TV. The FFmpeg information for your files look fine. I think there are two likely reasons for the skipping/stuttering issue:

• The video files themselves may have been encoded in such a way that your TV's firmware has problems decoding and playing them. This is quite a common occurrence. The way to test for this is to pre-transcode the video to another format. Right-click on the video in Mezzmo and click 'Pre-transcode Files'. On the Pre-transcode Files dialog, select your TV and click 'Choose Formats'. On the Pre-transcode Formats dialog, select the bolded format and select the 'Force full transcode of all channels' checkbox. Click OK and then select the 'Pre-transcode files even if they match the device's supported formats' checkbox. Click OK to start transcoding. Once fully transcoded, try streaming the video again. If it plays smoothly, then it is likely the original file has encoding issues or is encoded is such a way that that your TV's firmware has problems decoding and playing them.
• There may be a lot of DLNA/UPnP traffic on your home network from your PC or other devices. This is known to affect Samsung devices when streaming. As a test, try turning off other devices on your home network so that just your PC and TV are active/connected. Try streaming now and see if that improves things. If no improvement, try extending the SSDP advertisement interval to 86400 (=24 hours) - see this FAQ: http://forum.conceiva.com/showthread...ement-interval

Greetings again.

I had the time to try it out 2 more times with some changes and the stutter seems to be reduced to only 1 time (with both tries), and it feels like its close to at the same time or perhaps percentage, i should write it down next time. Something must have have helped because it was 3+ times before.

This is what i have changed

1. Downgraded to version 4.1.0.0
2. Disabled both windows media player and my cable set-up box from announcing themselves on the network and made sure all network devices were off
3. changed the SSDP advertisement to 86400 as advised

I haven't tried the Pre-Transcode yet because when i try to use the items that are bold it gives me this error message: Deliver media files not supported by the device: (Matroska -> h264 (30 fps), -). The only bold parts were under matroska -> h264 (30fps) for video & ac3 for audio

Update: I have tried Pre-Transcoding with matroska -> vp8 and vorbis and i still got 2 time skips, these were not marked in bold though

Should i also try to change the <packetsize> in my device profile file?

Sincerely,
James

If you consistently get the skip, then you can send us a set of logs and we'll see if we can see anything the could be causing the problem. Turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Reproduce the skipping problem and then stop your Mezzmo server and exit Mezzmo app. Zip up all the logs and email them to us at support [at] conceiva [dot] com (or upload the zipped logs to filesharing site like Google Drive, Dropbox, OneDrive, mega.co.nz, etc.) and email us the download link).

As fate would have when i tried it just now i got no skips on the first try, but the second video gave me skips. I have sent the .zip archive to your mail, its only 600kb so i figured it could be sent as an attachment.

What i did was clear the logs, enable logging, restart the program, viewed the video, stopped the video at the time skip, disabled logging, exited the program and then zipped the logs.

As a side note i was thinking and looking back i think all the time i got time skips i at least paused the video at least once, to get a drink or something else, could that have any influence over it?

Sincerely,
James

Hi James,

Thanks - we'll analyse the logs and report back via email. Pausing the video should not matter (from Mezzmo's point of view anyway). Perhaps try it again without pausing to see if it is a quirk in your Samsung TV's firmware.

Greetings,

I was able to do some tests again only sadly i kept getting disturbed forcing me to pause the video. But i did the next best thing, i excessively paused the video and see what would happen and i can confirm that im 99% sure that is the problem.

Every time i pause a little while later the video skips, its just long enough after resuming the pause that it seems coincidence, but after pausing the video 10 times and getting time skips not long after each resume im quite positive that's the reason.

Do you think there is anything that can be done with the software to fix this, perhaps in the profile or something? Or is this really a problem with the TV?

I also got a return mail for the mail i send you with logs saying:

Delivery to the following recipient has been delayed:

Message will be retried for 2 more day(s)

Did you receive my mail or should i resend it?

Hi James,

Well done on troubleshooting it down to possible Pause/Play issues. If your email has bounced, then please upload the logs to a filesharing site like Google Drive, Dropbox, OneDrive, mega.co.nz, etc. and then email the download link to support [at] conceiva [dot] com. After we get your download link, we'll analyse the logs and see what's happening with streaming to your TV.
