Hi!

It's me again :)

I'm playing film thru Mezzmo to my TV - Samsung LE46C650, after 10-20 seconds, film stops and Mezzmo plays next file.
File is transcoded realtime (with speed of >35fps, so there is no 'buffer underrun'.
ffmpeg can transcode that film without problems (i can run ffmpeg.exe without problems with that film)
Maybe it's a problem with TV (tv stops responding etc., then Mezzmo plays next file) ?

I'm sending you logs by email.

Regards,
razor

Hi,

Thanks for the logs.

One thing to try is to play around with the "contentlength" parameter in the device profile. It takes values from 0 to 3 (inclusive) and even 4, but that requires a bit more modification of the device profile itself. Can you please try changing the contentlength from 0 to 3 (restart the server after each change of course) and see if that helps?

Hi,
I am evaluating Mezzmo software and I am experiencing the same issue described by razor on my Samsung UE40C6500UP TV set.
It is limited to "some" mkv files and this behaviour is really annoying. I experienced the same issue using Samsung PC Share Manager and that was a reason for looking to an alternative software. I was trying to apply your advice on contentleght parameter but I do not find it! The only parameters associated to "Samsung C" device profile are: connection speed, max video size and video bitrate.
Do I have to edit a configuration file?
Thank you in advance!

Hi Roberto,

Yes, the "contentlength" is inside the SamsungLA.prf file located in the DeviceProfiles folder (see this thread for its location: http://forum.conceiva.com/showthread.php/467-FAQ-Where-are-device-profiles-located). If you would like specific instructions on how to edit and change this, please let me know and I'll post them here.

Hi!

Got the same problem, and my contentlenght were already set to 3. Any other tips? =)

Paul

Hi,

Have you tried other contentlength values (from 0 to 3)? Do they make any visible difference or all of them feel the same?

The problem with transcoding is that you need a pretty powerful CPU, since ffmpeg does not support GPU transcoding at the moment.
Second of all, if you want to transcode your *.mkv containers (which most likely encoded with h264 or ac3) to a format supported by your tv, you'll need a quite extra HDD space (depending on how big and how much bitrate your movie has, you need temp storage ~ 20 to 100GB). This is because your movie needs to be "converted" to format like mpeg or avi which can be pretty big in size (not as big as mpeg though).

im having exactly the same problem with you, then i tried this

one solution is to check / tick the option in your transcoding option that says something like "continue transcoding in the background, for previous movie" i dont really know the exact option, since im not in front of my desktop computer. Then try to play your the movie you want to see, then like return back to main menu and wait like 20 mins or 30 mins" then you should be able to watch the entire movie.

Paul
06-16-2010, 02:57 PM
Yes, you are correct. We're also working on optimizing transcoding as much as possible to make it faster, but there's only so much you can squeeze out of FFmpeg. The idea with starting a movie and letting it finish is right - for the time being that's the best way if your CPU doesn't cope with real-time encoding. In a future update we plan to have something that'll help with that even better.

And yes, please check how much space you've left for temporary transcoded files (20GB by default), as they'll be cleaned up once that limit is hit and you might find yourself transcoding more than needed because of that.

Hmmm, but thats still not explaining why a restart solve it? And why does it need to transcode .mkv's, it is playable from a memorystick.. :confused:

Paul
06-16-2010, 05:05 PM
Well, playing files from a memory stick may use another engine (or may not - maybe it's one, some devices have just one internal engine to play files, some have multiple), so it's not guaranteed that if something can be played from a memory stick, it can be played via DLNA (unfortunately). However, in this particular case, it may be due to an issue that we've just discovered and are fixing that may abort or freeze playing even of native files. I'll keep you posted on our progress.

Hey again!
Saw this thread: http://forum.conceiva.com/showthread.php/535-Unable-to-discover-Mezzmo-service-from-my-Samsung-TV/page2

the configuration he is doing here, does this fix the transcoding problems? Thanks in advance ;)

Paul
06-18-2010, 10:20 AM
Yes, if the files don't need transcoding, they should be added to the device profile so that Mezzmo simply passes them through.

If you post FFmpeg information about the files that you have, I can tell whether they will be passed through or transcoded.

Also, please let me know what's selected in the Media Devices dialog as the device profile - Samsung B or C?

SaabAero

Im using the samsung C profile. Dont sure if this is right really, but in the device list, the tv is named Samsung C..

Thanks for the FFmpeg info.

Both of those should pass through and play natively on the Samsung C series TV (and B series as well probably).

Can you please generate a log file (see this thread: http://forum.conceiva.com/showthread.php?t=419) of trying to play one of those files and send it in to support (at) conceiva (dot) com for further investigation?

Also, if you have any *.pro files in the DeviceProfiles folder, please try deleting them and then trying to play the files again (but do make sure that the correct TV model is detected and used by Mezzmo in the Media Devices dialog). Please restart the server after deleting *.pro files.

Yes, there is more progress. We've currently identified and fixing one more issue that's related to transcoding. Once we have a patch I'll send it to you via e-mail.

Is that patch for his tv only, or will it work on any C-series tv's? Still got this problem :)

It's a generic patch for any device - basically fixes some network streaming issues that can cause stuttering or loss of connectivity in certain conditions. If you wish to try it, please send a message to support and I'll send you a link.

SaabAero

Thanks! Solved my problems :) Will this patched server come with the next version of mezzmo? Pretty urgent in my opinion, as i know some pals which also want a stable server ;)

Paul
07-05-2010, 08:50 AM
Glad to hear it's fixed your issue. Yes, it'll be part of the next official update, which is possibly due out this week.

paulo
07-07-2010, 05:05 PM
Is this patch also applicable to case when transcoding is not in place? I have such issue with my Samsung "C" series on files that do not require transcoding and play normally on the same TV from USB stick (regular avi).
If yes I would give it a try.

Paul
07-08-2010, 08:52 AM
Yes, it applies to playing files in general - we've spent a bit of time on getting network streaming fixed over the past few days and we should have something available very soon.

Sorry to resurrect an old thread, but should this be already solved in the latest version?

I've started using Mezzmo recently with my Samsung C6530 and I have a simmilar issue. Usually on full HD movies, after playing for a while it just skips to the next file.

The TV is connected via 200 mbps PLC to the router.

jbcain
04-14-2011, 04:10 PM
whats your actual throughput on the PLC? i tried the latest PLC stuff a few months ago and it was absolutely garbage. My throughput was faster on wireless g.

Paul
04-14-2011, 04:11 PM
It depends on the actual issue - if the transcoding is too slow, then that's more of a hardware issue. All current connectivity/streaming issues we were aware of have been fixed in v2.3, so please update to it and see if it helps.

If it doesn't, please turn on logging (see this thread: http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) then try to play that movie again and once it skips to the next one, stop the server and send the logs to support (at) conceiva (dot) com. Also, please mention what CPU type you have.

I got the same problem. While it's just stable, sometimes, when I try it again, it plays all the way through. But sometimes, I have to try it many times. Plus, a lot of times, I can skip, so I have start from the beginning again and again. Very annoying.

I have tried to change contentlength to 0/1/2/3, didn't help.

Can you please send in the logs (or check yourself) to see the transcoding speed of the file?

Where to find the transcoding speed? I have emailed the log files.
I'm using contentlength: 0. I tried others and got the same result.

Thank you.

Sorry to be a pain, but i get this too on my C650. Its random so not sure when i can send logs etc. i thought it was just me!

I've always ticked the box to disable all transcoding as my server is a mere Pentium4 and doesnt really have the transcode power. Anyway all my files are supported by TV natively, either MKV or AVI.

Any thoughts?
thanks

If the files are not being transcoded, then it's probably something else. Would it be possible for you to send one of your files to us (via www.megaupload.com or a similar service), so that we could try it here? Does it always happen on the same file in the same spot or is it random in a sense that it can occur on any file at any given time?

Gus
06-07-2011, 08:44 PM
its totally random and can happen on any files, file types, folders, times of day etc. When it does fail, it always occur within the first 1-10seconds. And moves to the next file. Once i stop and reload the first file it plays fine the second time no problem.
i will try to make an effort and get you logs since i know you are in the dark.
cheers

I know I maybe completely in the wrong direction here, but when I updated to the latest 2.3.2.0 I had the same issues that my films would stop randomly and the next film in the list would start.
I deleted the transcoded files in the temp folder as it was seeing that the folder was full (max 80gB ) although this had to be incorrect.
I have native files and transcoded files in my libruary and all were doing the same, now I have no issues.
I am using the Sony Bravia KDL profile.
