Oppo BDP-83/93/95/103/105 DLNA/UPnP thread - Page 15

Having mixed results here after a couple hours playing around with the new version (first time I have tried the program). 16 bit flac files are playing fine but 24 bit flac files terminate playing anywhere from about 1 to 2 minutes into the tracks. Very strange. I also can't determine whether or not it is actually passing a 24 bit lpcm stream or if it is downsampling to 16 bits. Artist option on menu tree is not working for me (freezes up) but the Folders option seems to work well. Very nice except there is no A-Z sub menu so it takes way too long to scroll through to get to what I want.

Another new owner here.. just got my 83 last weekend.
First thing I wanted to test was that it can really stream/play DVD ISOs off
my PC. Setup was a breeze and I was able to sucessfully play the
DVD movie tracks off the .ISO files residing on my PC. I just followed the
procedure mentioned by couple of folks earlier and use PS3 server.
It really works.. although with the few minor limitations already discussed
here. Didn't experience any stuttering in playback. Smooth A/V.
Many thanks to all for the valuable information in this thread.

I have been working with Dennis at Conceiva for the last month to get Mezzmo working with the BDP-83 and writing a profile to support as many filetypes as the Oppo can either play natively or transcode to a filetype it can. The result is what you see in the current release.

I'm still working on tweaks (as the transcoding is largely dependent on what libraries are in the copy of FFMPEG Mezzmo uses.

Currently, Mezzmo is transcoding FLAC (and any other audio file that is not an MP3) to 'signed 16-bit big-endian LPCM' as the BDP-83 'likes' those. I haven't had a 24-bit FLAC available to try similarly with 'signed 24-bit big-endian' (or little-endian - or unsigned versions of either, for that matter). Send me one and I'll try profiling for it and see if it works - assuming my PIO VSX-D608 can deal with a 24-bit stream ... don't think I've ever tried one.

The whole DLNA thing has involved my creating a standard file in every variant audio/video/image encoding I can think of as well as every container I can think of and trying them all out untranscoded, transcoded and with and without whatever DLNA format tags I can guess the Oppo migh be suporting. The upshot is that I know empirically, for the most part, what the BDP-83 supports via DLNA and what it doesn't in the 1224 firmware iteration.


I sent this email to Oppo Support on the 21st - so far no answer. I gather that they usually reply promptly, so this may be something internally sensitive to them even though the Certificates are publicly available on the DLNA website if you know the number.

Hello,

I am a recent Oppo BDP-83 purchaser in Canada. I am very satisfied with the performance of the player from DISC and USB sources.

I am now investigating the use of the player's recent firmware update to enable the use of a DLNA source.

Has Oppo submitted the BDP-83 to the certification testing administered by DLNA and received a DLNA Test Certificate?

If so, could you please send me a copy of the Certificate or the Certification ID ( the REGxxxxxxxx number) of the Certificate?

This will assist me in configuring DLNA server software to deliver the correct information to the BDP-83 player to enable it to properly render the audio/video/image data.

I am specifically interested in the Media Format Interoperability section of the Certificate.

Thank you.

Wow, thanks Chris for all of your work on this! Here is a link to some 24 bit files that you could use for testing: http://www.archive.org/details/skb2005-10-22_24bit

I can't believe I never tried this before but I just tried streaming 24 bit flac files on foobar (ver. 1.0) and they are playing without any problems at all. Settings set to max bit depth of 24 and max sample rate of 192k. No menu tree navigation issues so far either. The only negative is no gapless playback although I have not seen gapless playback work with any other server software either. Fortunately the gaps are fairly brief. So far, this appears to be the best solution for me for audio playback.

Is that this product? http://www.foobar2000.org/

Yes, but you'd want the plugin for UPnP. There's also a plugin for DVD-A/MLP.

Here, Foobar is down-sampling everything to 48KHz regardless of the settings. I can't tell if it's still 24 bit. Not sure what the "dithering" option does on the bit depth, it works both ways. Does seem to work as well as anything else though.

Thanks for the link.

Setting up a 24-bit transcode codec didn't work. And I've now found evidence elsewhere that the DLNA spec for PCM accepts either signed 16-bit little-endian or signed 16-bit big-endian and nothing else.

Effectively - DLNA is a constrained subset of UPnP, so if you want 24 bit, you may have to investigate one of the UPnP-only media server apps.

Charlie Miller recordings are awesome and that incarnation of the Steve Kimock Band was fantastic! I'm gonna have to DL that one, thanks!

(sorry for the off topic excitement)

I think there are a few other tasty 24 bit Miller recordings up there from that same lineup as well. If you like the Dead, he also recently started doing a few 24 bit remasters of some classic '71 shows that are available over on Lossless Legs.

I'm a bit confused by Ka1hode's post above stating 24 bit can't be streamed via DLNA as I thought a few folks had definitively confirmed they were getting 24 bit output from both Asset and JRMC. Is that spec stating 16 bit limit perhaps outdated or maybe not so tight somehow? Does anyone know of a capture program that I could run on Win7 to analyze the output streams of these programs?

Asset is a UPnP server, I'd assume the same for JRMC.

J. River Media Center has a DLNA Server, Renderer, and Controller.

DLNA and UPnP are very close.

24 bit media files will work if the renderer supports them.

We sometimes see this type of termination and we're working on it. Our best guess is that the network connection is occasionally dropped.

If you're using wireless, it might be worth trying a wired connection as a test.

hi guys,
I downloaded TVersity Pro, replaced the profiles.xml with the one linked at the beginning of the thread, but even though the Oppo comes up as an Oppo in the status section, I have no links to Hulu, Youtube, etc. What folder would those links be under in the Oppo? Should they just appear once you select TVersity?

Any help would be appreciated

Also, is it possible to play back albums in track order? Every media player I've tried goes to alphabetical order, I don't know if it's just how it works or whatever, but I was curious.

Well, all three of those statements are true, but the third is incomplete and therefore potentially misleading, so let me clarify ....

DLNA v1.5 supports transmission of 16-bit PCM audio format only. 24-bit audio via DLNA 1.5 is supported in the WMA audio format only. The Oppo supports 16-bit PCM and thefore can play a 16-bit FLAC file that has been transcoded to it. The Oppo does not support WMA via DLNA and therefore will not be able to play a 24-bit FLAC as 24-bit however it is transcoded. The best that can happen is downsampling the 24-bit to 16-bit PCM.

I await confirmed results to the contrary and would be pleased to be proven incorrect.

DLNA 1.5 also supports transmission of MPEG-1 Layer 3 (MP3) format audio and the Oppo supports that as well.

What I have not yet tried is 24-bit PCM audio format via straight-up UPnP. That's on my plate for sometime later this week, so we'll see.

Chris

Not over DLNA; it does support WMA on local storage.

I don't know the cause of this restriction.

-Bill

Even though this is the OPPO DLNA thread and the post was about audio over DLNA, I have edited the post to clarify this point.

Thanks Bill.

Chris

Is there a way to stream from the Oppo to a computer?
(The normal way is from the computer to the Oppo.)

My mind is blown!

I don't think it can be done, why would you want to?

So as to have a bluray player hooked up on my computer.
Then I could make a personal copy (compressed) of certain blurays.
Ingenious, isn't it?
But like you, I suppose it can't be done???

Wouldn't it be easier to use PC software on the PC? BR drives are not expensive.

-Bill

Sure, it would be simpler.
But if I could save some money, using the Oppo as a bluray player for my PC, I'd be happy. I'm not ready yet to invest in buying a Bluray drive (it still costs some money, at least in France).

h.264 would be excellent as that could mean it'll play my MTS files generated from the HD cam. Currently it'll on play them from USB and in the original directory structure the camera sets up.

I have played mp4 files (not h.264).

--

If they can also support WAV, then I won't have to re-rip my entire library to high bit-rate MP3.

With PS3 Media Server, I have good results streaming blurays compressed in mvk (h264).
Out of 20, there are 16 I could stream fine.
"Only" 4 I couldn't (ie when streamed, there were horrible visual artefacts).
(So there probably are some settings concerning the encoding in h264 which do not work well when streaming with PS3MS to the Oppo, but I haven't identified them.)

Another possibility is to package an mkv into a avchd folder, using the free program multiAVCHD.
The avchd folder is then put on a USB drive connected directly to the Oppo.
But most of the time, when the result is good (no visual artefact), then I can also simply stream the mkv through PS3MS.

Thanks for trying Mezzmo!

If you still are having those issues, I'd be happy to help you here or through support (at) conceiva (dot) com . At the moment FLAC files are resampled to 16-bit LPCM. We've tried 24-bit LPCM, but it seems that Oppo didn't accept that (I'd be happy to test it more if you're interested and can give me a hand, as I don't have a unit here).

I'd be interested in why the artist tree is freezing (would need a log file for that).

In any case, please let me know of any Mezzmo issues, so we can fix them up.

Have you tried J. River MC14 with added DLNA support?

I have a BDP83 but just have the PC connected direct to TV; still this is interesting.

Read all the pages; however could not find an answer:

I have an Acer H340 which is DLNA enabled but the oppo only picks up .mpg formats and nothing else (ie no mkvs show up in MediaServer\\Video) - any reason why this would be? I am pulling my hair out here..

The simple answer is that the DLNA mediaserver app in your ACER does not support MKV, or likely AVI or OGM either.

At root, DLNA is a consumer electronics format invented to ensure that consumer generated files from 'standard' home electronics like digital still and movie cameras, televisions, cellphones, etc. can all interchange. By 'standard', that means MPG, MP3, JPG, PNG and so forth. FLAC, MKV, AVI, TS, OGM and the like are considered by the consumer electronics industry to be 'piracy enabling' formats. The odds of finding them supported in a consumer interoperability format for streaming files are vanishingly low.

Call me cynical, but there you are.

Individual devices may support these types of files via disk or USB because each copy has to be generated for each individual use. Streaming may very well be supplying more than one viewer at a time (so they think).

Standalone software for DLNA serving can get around the DLNA restrictions by serving the 'rogue' formats by UPnP so that, if the receiving device supports them, they can be played.

The Oppo supports MPG (1 and 2) video (with any of MP2, AC3 and 16-bit PCM audio), MP3 and PCM (16-bit) audio and JPG and PNG images via DLNA and MKV via UPnP over its ethernet connection. Within the MKV wrapper, it additionally supports H264/AVC (Mpeg 4, Part 10) and XVID/MP4 (Mpeg 4, Part 2) with any of AAC, MP3 or 16-bit PCM audio. Anything else (currently) needs to be converted by the mediaserver software to one of those formats or wrappers or formats within wrapper.

Oppo is NOT really responsible for the deficiencies of DLNA and I'm quite pleased that they undertook to enable ANY functionality of DLNA/UPnP over the ethernet connection at all.

Chris

Question -- I'm not familiar with MKV other than that it is a container.

Does that mean I can convert my MTS AVCHD video shot with my HD CAM to MKV without re-encoding the video/audio? If so, great! If not, then I'll have to hope Oppo adds playback of individual MTS files...
