Samsung UN46C8000XF: Mezzmo vs. Samsung DLNA server

[glc650]

I took 3 of the AVCHD camcorder recordings that I last had trouble with (when I was trying to playback a bunch of my video for friends during the holidays) and remuxed them into 3 different containers (mkv, m2ts, ts) and all 9 files (3 recordings * 3 different container files) played back just fine. So that brings me to the following conclusion:

the high bit rate (22+ mbps according to ffmpeg on the native .mts files) of my recordings isn't the issue, the issue is either:

1) .mts plus high bit rate video streams is an issue for Samsung 3D (or maybe just .mts files in general? not sure as my recordings are the only native .mts files i have)
2) Samsung handles hight bit rate .mts files just fine, just not the ones from my comcorder for some reason (again, I have no other native .mts files to test this theory with)

NOTE: This test was performed with the latest Mezzmo but not the latest Samsung C (TV) profile. I didn't bother testing the 3D BDP profile as I've had better luck with the Samsung C profile since I started using Mezzmo and regardless of the device (46" C8000 3D TV or C7900 3D BDP). According to Mezzmo email support (last week), the latest Mezzmo update includes the latest Samsung TV/BDP profiles but I didn't think of that so after I updated I copied over the previous profiles (from support email) rather than using the built in ones.

We've found .mts files from several camcorders with higher bitrates that will stutter on the TV. It appears to be limited only to mts files with bitrates over 16 Mbits.

Do those remuxed files play fine using PCSM as well? Mezzmo may have been transcoding those (unless you know that you've turned transcoding off).

[glc650]

I'll try them with PCSM asap. Transcoding is enabled but there are no files in the transcoded files folder so I'm assuming Mezzmo was not transcoding in my case.

Is there another work around (besides remuxing)?

[Paul]

If the TV won't play them as-is, then we have to remux - there's no work-around, unfortunately. Let's see how your tests go as well and we'll proceed from there.

At the risk of confusing the problem you are working on here, I'm going to add my two cents, because I think we may be working the same problem. If they are different problems then just ignore the post.

I'm in the middle of a similar issue with Mezzmo support. My TV is a Samsung LN46C600 using the Samsung C profile. The AVHCD files from my camcorder are saved with a MTS format.

The TV doesn't recognize the MTS file type. But, if I change the extension to MPG, making no other changes, just changing it from .MTS to .MPG, the file plays fine on the TV. This is true when playing the file using PCSM, using the DLINK DNS-321 DLNA player and Mezzmo (with transcoding off).

So the TV is capable of playing the file at the bitrate. But if I try to play the file with the MTS extension; Mezzmo won't do it unless transcoding is enabled. This obviously doesn't make sense as the TV can play the file directly.

You may want to try renaming your MTS files as MPG to see if your TV can handle them this way also.

My next step with Mezzmo support is to run a program called Wireshark. I assume it is some kind of profiling tool. Not sure where it will lead but I'm thinking that a tweak to the device profile to treat MTS files the same way it does MPG would solve it.

There's also a possibility that the internal player on your TV is closer to the one in Samsung BDPs, which do play MTS files fine - as a test, try changing the device profile to "Samsung BDP" (or BDP 3D) and see if that plays the MTS files directly without transcoding and without stuttering. Please let me know how that goes.

That appears to work like a charm for me! Thanks.

[Paul]

Great! I'd recommend using that profile then.

Mezzmo (Samsung C and BDP 3D profiles):
renaming files to .mpg = buffering
renaming files to .ts = buffering
remuxed .mkv = slow motion and audio out of sync by a bunch
remuxed .m2ts = buffering
remuxed .ts files play fine

Samsung PC Share software:
same as above except .m2ts files aren't detected and files renamed to .ts play fine

So looks like the easiest work around is to use PC Share and rename my .mts recordings to .ts

I have purchased a Samsung UA55D6600 and I am testing Mezzmo.
I have a Panasonic HD recorder.
I am trying to watch HD 1920X1080 video and the files are M2ts.
The playback starts but then constantly stalls and buffers/loads. As others have experienced.
I have tried the profiles suggested Samsung BDP and BDP 3D same result.
Also tried transcoding off and on. No joy.

Any suggestions/ideas.
Thanks
