Mixed results w/DLNA trials
« on: September 20, 2012, 12:59:57 pm »

I decided to spend some time looking into this, for the time being.

At first I was gonna use my WDTV Live, but for some reason it doesn't like browsing its own DLNA server list and will result, just by flipping thru different selection options..

So I decided to try my Samsung BD-E5300  Blu-Ray Player.   Figured its Samsung, and its not too old, so it should be pretty decent right?

Well,  I get mixed results even using the Samsung Profile.

I pretty much have to use the  Mpeg Mimetype  Override to get anything working,  as far as my MKV's go.   Most of them are a mix of  Xvid,  Mpeg4 AVC, etc, even if its set to  Never Convert, or  Convert Always, or  Convert Unsupported.

So the MIME override gets my files to at least show video.   But so far I can't get anything other than  videos with an  AC3  for a primary audio track, to play any audio.  It always comes up unsupported,  no matter what conversion strategy or format I use..   FLAC aside, this player should be able to play  MP3,  AAC-LC, etc.

Interesting note.   The player seems to ignore the  Video DLNA: Override   info even when its changed to gibberish.
I don't know why the player ignores even converted audio (assuming its being converted),  but I played my  FF7 OST  which is FLAC and that worked fine  so I assume  Audio conversion at least works..

I don't know if this will help the Dev team at all.   But those are my observations.

edit:  I did a speed run through the Menu on my WDTV,  and it appears to play anything I throw at it, even shows multiple audio tracks, etc.

Clearly this is a device support issue, but  I hope any of the info helps,  for workaround ideas, etc.
I might be willing to loan the BD Player out if you return it in a timeley manner,  so you can study its  idiosyncrasies - if you wish.

The only video format required for DLNA certification is MPEG2. Previous generations of Samsung players refused to play any files unless they were labeled as MPEG2 in the DLNA flags and mimetype (hence the override). The override should be enabled and set to video/mpeg and the DLNAType should be set to MPEG_PS_NTSC or MPEG_PS_PAL depending on your location. Now that said, since the underlying software playing the video is often able to play more than MPEG2, the requirement for MPEG2 is kind of a gatekeeper in the samsung firmware, after it gets past that, the file is just passed along to the underlying software player which may just go ahead and play it even if it's some other format.

DTS and mutichannel output are often not supported through DLNA, especially by BD players and TV's. If you have a lot of material like this your best bet is probably to turn on conversion to mpeg2/dvd or mpeg2/dvd pal.

Interesting to know, thanks.

I will try those specific overrides you mentioned,  but then I suppose I would have qualms about  converting stuff  "down" to  Mpeg2/DVD   picture-quality wise..    But I will definitely test those mime types you listed,  as I think it even differed from the default that was listed,  so I'm interested to see how that works out.

Although I will say again, I appears to have no problem playing video streams after I simply turned on the mime override,  the problem seemed to be with audio (a lot of it AAC)  and nothing in those conversion settings seemed to work.   The BD-Player  seemed to handle  AC-3  multichannel content just fine (I tested Gundam F91 & Char's Counterattack).   I also tested my encode of  Jin-Roh: The Wolf Brigade,  which has multiple audio tracks,  I think the english AC-3 track was first because I got sound from it.    But  I also have Skycrawlers,  which has multiple tracks with  FLAC, AC-3, and I think an AAC track.    The BD-Player should support AAC, MP3, etc (unsure about FLAC)  so I dunno why its giving me so much problems.

My main concern is definitely with audio tracks,  especially  files whos first track may -not- be an English track,  as I don't seem to be able to switch audio tracks ("not available")  but I don't know if that is really a JRiver issue or not, because my  WDTV Live  can select any audio track,  doesn't require  any mime overrides, etc (better playback quality too.. I think).

In any case this is mostly experimenting,  as I will eventually have a PC setup for playback and storage of my libraries.  But having my library accessible by others is a plus.
Thank you for your time.
