MKV file unnecessarily transcoded for Samsung C

[bieniu]

I really like Mezzmo. I really enjoyed the first days of my trial period as I could easily see that Mezzmo works much better than Samsung PC Share Manager on my Samsung C TV. I really love the transcoding functionality. The only drawback is that the profile for Samsung C TV seems not to be very well tuned to the real capabilities of the TV. For example I noticed that some MKV files are unnecessarily transcoded. I could live with this, but unfortunately if the file is a movie in high resolution, the transcoding is not fast enough to let the movie play. As a result the movie becomes unplayable. Of course it is played well without transcoding from a HD or via PC Share Manager. Is it possible to somehow modify the profile?

This is the file which is unnecessarily transcoded:

While this one (also MKV in hi-res) is played well and transcoding is not triggered:

1. Is there any chance to upgrade the profile?
2. Maybe you have the detailed documentation for .prf files available so the users could try to upgrade the profiles themselves and then send it back to you?

[Paul]

We found that some Samsung TVs' built-in players are actually closer to the BDP ones - maybe try one of the Samsung BDP device profiles and see if that works better for your particular TV model. What model do you have?

[bieniu]

Thank you. You were right. After switching the profile to "Samsung BDP" both files play correctly without transcoding on my UE40C8000. Great! However I have two additional questions:
1. What is the difference between Samsung BDP and Samsung BDP 3D profile? My TV is 3D, but BDP 3D profile suffers the same problem as Samsung C profile. I wonder what I miss by not using 3D profile.
2. To easily solve compatibility problems like this in the future, would it be possible to add option to control transcoding on a per file basis? You could browse Mezzmo library and set "Transcode" setting for each file separately to either Yes (force transcode), No (force no transcoding) or Auto (default, decide on transcoding based on profile selected). Having this option users could manually fix the problems caused by profile not matching real TV's capabilities. What do you think?

[Paul]

There's not much difference between the BDP and BDP 3D profiles - the 3D one is closer to the C, so that's why you're getting same issues with it. You're not missing anything, so just use the BDP one

We will have an option to pre-transcode your library and that will allow you to transcode individual files - so, thanks for the suggestion, it's already planned! Ideally, our device profiles should reflect the device's capabilities, but it will take time to make them perfect Please also feel free to let us know if you have files that do not match the device profile, but are supported natively by the device, so that we could adjust our device profiles for everyone's benefit.

[Gareth]

Hi - I also had this transcoding issue and it was fixed by changing the profile to Samsung BDP from Samsung C (my TV is a Samsung C650).

I do have another problem that is probably profile related: Using Samsung PC Share Manager I can stream VC-1 encoded MKV files but using Mezzmo gives me an error on the TV that the format is not supported. Any ideas? I tried a few other profiles with no luck. I have transcoding disabled.

[Adric]

Can you right click on the file in Mezzmo and get ffmpeg information. Please post it here.

Gareth can you please send into support and we can send you a patch. support (at) conceiva . com

[Gareth]

Adric sent me a new Samsung C profile which I'm pleased to say has fixed the issue. Hope this goes into an update soon.

Next question Is it possible to have some sort of chaptering support or make the ff/rw jump more that a few seconds? Chaptering works for files connect to the TV via USB. Is this a limitation of the device or Mezzmo? I don't remember if Samsung PC Share Manager offers this as I uninstalled it PDQ.

even with Samsung PC Share thing you can only do the random 20 seconds or whatever FF. and it doesnt seem to work on every file, sometiems it does nothing, not sure why
