Samsung HT-E5550 Audio/Video Synchro 1080p h264 issue

by Greg_PL / May 30, 2013 3:24 AM PDT

Hello All.

First of all, I would like to apologize for my bad language if you notice it. English is not my native language but I also know it's not an excuse.

Before writing a topic in here I already contacted Samsung Support regarding this issue but their answer was... Well, let's say they just told me to send the device to their service to check it out because data for the issue I provided was valid so service the device would be the first choice and the best. But before I do this I would like to ask on wider spectrum regarding the case.
So basically, I bought a BD Player (HT-E5550) few weeks ago. It's updated to the newest available firmware. It's connected to the 1Gbps switch for the LAN connection. Blu-ray plays well, no issue there. The problem began with h264 files in mkv or mp4 files. 720p files play well, without any issue. Screen is smooth. Then it comes to 1080p. Screen is smooth, no playback issue. But each time I run 1080p movie from mkv/mp4 file the sound is like 500ms to 1s delayed in time. Samsung Support told me there might be an issue with files if they were bigger than 4GB. Then I've read their manual on files that are compatible and their codecs. Each file I tried to play was valid. They mailed me back even confirming this. But in their manual for mkv file max bitrate for file is 25MB/s. Simple calculation gives a file of 20GB with that bitrate and DTS sound for 2h movie in 1080p. Then why the 4GB size causing problems? No idea. I have run 6GB 720p movie without any issue with audio/video synchro. But ever a 1.2GB file with 1080p had this problem. I tried to run those files from DLNA server (1Gbps LAN), Pendrive, DVDR, BDR... each time there was the same issue. Sound was delayed from 500ms to 1s. No matter from which source I have played this. My question is, does anyone who had/have this player encountered the same issue?

What you find is that different playback devices may differ in that delay. Most folk standardize on PC playback but as this is not a PC you discover that as you try more devices from tablets to TVs this area is awash with issues like this.

I see in VLC Player a sync adjustment so we can correct in the player on a PC for this but in the case of BluRay and TVs you get to re-encode the content to work on the devices.

Some feel this is a flaw but from what I'm seeing, this is how it works today.

In reply to: Yes.

I just wonder. When it comes to 720p files - It's all OK. But when it's 1080p it's loosing it Synchro. Then I ask myself. If Samsung Support said the file should play ok and they told me I could get the device checked in Authorised Service. Is there anything in the device that could lead to lose the a/v synchro only at 1080p files? Sadly while playing the 1080p file on PC it is ok, when in the Bluray player it gets delayed. Maybce device cpu/gpu/whatever have a factory flaw and it's not handling 1080p well while it should normally?

Re-encoding whole file (for mkv file It's fast, just set delay in container for the audio) is kinda pointless. Because while I will play it ok on my Bluray, then everyone else (if they get the file) will see it with broken synchro :/

Always call such in.

But be prepared to run the gauntlet of making sure it's in a supported encoding. Let's be very clear that these devices may play encoding that is not in its documentation and as such will not be considered a flaw. So you get to grind on the fine details, check the product documentation and then a few other final issues to deal with.

I hesitate to write about this but for completeness will share that a buddy was griping about this and I asked for an example. They handed me a stick and it was a title that was not available for digital download. That is, they had got it from some torrent site. We can't ask that such be fixed. Think about that.

So he came up with other sticks and each one was some download that was less than legit and you can see why there was no support for that content.

Finally I took a look again and the encoding (I use MEDIA INFO) was not in the player's document so that was that. Yes, they did exclaim "it plays but with issues."

Be sure you have your details at the ready to call it in.

Hello. Thanks for fast replay.

I presented everything to Samsung Support and then I've got the answer: Visit Service with your device. If you look on the Manual for HT-E5550, there is a list of format/resolution/codec/profile/transmission compatibility

Now I will show you what I wanted to play there on the device:

Title that was not available for digital download doesn't mean anything to be honest with you. World is not spining around files like that to be the only ones that should play ok on devices. I presented the files info to the Samsung. Their answer was: "Files are indeed valid, please visit Samsung Service"..

My question is: is it possible for the device to be 'broken' only for 1080p when 720 works fine?

If they think it needs service, then it needs service. Your replay about the world spinning is odd. I can't decode what you meant in that sentence but my buddy was good enough to know we can't expect support for pirated content. There are some that think that all is fair game. But that's another discussion for another day.

Let Samsung fix this.

Why do you think it's pirated? Because I said it's not digital download? First Impression is not always right. Nowdays 'legaly encoded' digital downloads get pirated mostly. And when it comes to encoding a video off the source which for example can be Bluray. It doesn't matter. I can be ripping all my Bluray's to mkv/mp4 just to have instant movie library from an DLNA server instead of searching the tittles from the cabinet Happy But this is going off-track. My original question was - if anyone had the same issue with this device which was problem with proper audio/video synchro on 1080p picture.

Why yes I've seen this on too many devices.

I don't have this model and shared the story but it does happen on many devices. Did you try another device? I have.

Since Samsung is willing to fix it, why delay?

Just to make a notice on the case. Seems that newest firmware fixed the issue permanently : )
