Universalmediaserver: No files on Samsung TVs

[SubJunk]

@drakulis this might be related to your Samsung resuming contribution, are you interested in looking into it? We have two reports on the forum that look like they might be describing the same thing, the second one has a debug log.

The only thing I've noticed in the log which may cause such issue is a X_GetFeatureList request which cause error in the UMS:

As I see it is also Samsung specific request. It is possible that now, when UMS is registered as a AllShare service some Samsung devices need it. I've tested it on my old (2011) D-serie model and it is running fine.
I will look on it todays evening and prepare patch for this request. We'll see if it help.

I had this problem only on my Samsung UE48H6600

On my Samsung UE32 F4580SS all files were shown instantly.

[drakulis]

yeap. It seems that some E+ serie Samsung devices are affected.

I think I just fixed it but I have just D-serie Samsung TV where this issue doesn't occure, so testers are needed.
@pipin77 could you please test it on your TV?

Could anybody else test it on other models E, F, G, H, I, J models?

Volunteers please proceed accordingly:

• stop the server
• backup your current ums.jar
• download new ums.jar from https://mega.nz/#!YnpkDCQY!JmrhYWOOHZYaT12UO5WgCR92JPCF-XBE1_i9c9KTw3A
• start the server
• check your Samsung TV if all files are in place
• change content type in your TV to Video / Audio / Picture and verify if everything is OK

If it is still broken then:

• stop the server
• restore ums.jar
• start the server

Please share your feedback here.

Got one response on forum that it works now on Samsung UE32EH5307KX.

@pipin77 could you confirm it on your device?

[pipin77]

Ok, here my testings for Samsung UE32 F4580SS Samsung UE48 H6600, both acted accordingly

server restart;
TV content type video, no files and folders are shown
TV content type all, files and folders are shown,
TV content type video, still no files and folders,
TV back to content type all and playing one video,
TV content type video, all files and folders are shown
after restarting the server same problem again.

After downloading the new ums.jar the problem was gone on both TVs.

Great! Thx pipin77.

@SubJunk PR is ready to merge. I suggest to create bugfix release ASAP while it may affect many users.

[pipin77]

No problem, thanks to you.
Great that some new developers are contributing to my favorite media player.

@drakulis thanks for the fast work, I will release as soon as possible :) Feel free to post the patched ums.jar on the forum in the meantime
