Oppo BDP-83/93/95/103/105 DLNA/UPnP thread - Page 20

Have you tried a small sample from a USB device? That might distinguish DLNA and network issues from codec issues

-Bill

I don't know how to carve up a 20 to 35GB file into a 2GB for fat. I suppose there are some bluray editing programs out there, but I don't think it's a codec problem (other than the VC-1 format shrinking). The OPPO will attempt to load and play the file and in fact often make it 2 minutes into the movie before it freezes. Some of my PIXAR movies have actually made about 5 minutes. Other people have reproduced this and we have never discussed streaming, DLNA server types, or LAN issues. I've tried several DLNA servers: JRiver (which for me works the best as it is my default media player), PS3 Media Server, Tversity, and one other that escapes me. I've focused on direct streaming w/o transcoding as there really is no need based on my file types. Side note I do transcode my wav files to PCM as OPPO doesn't accept them. That totally escapes me as to why they would not support the most common CD format out there in favor of lossy file types. I don't do lossy (yea I know bluray is to a point), and that is also why I purchased a SACD player.

I think it is 4GB for FAT, or larger if you use a DVD with UDF.

Maybe an extra, or a chapter selection would fit?

Diagnosis means eliminating variables, and trying the same file on both local storage and DLNA might tell us something.

Else, just report your findings to OPPO.

Ok, I found why probably you got white noise. First, you must rename your DTS files with extension .dtswav. This is very important and will make foobar recognize the files as DTS (you can see their properties in a playlist), without needing the DTS DSP which you can remove. After that, just configure the streaming profile to not convert to stereo, and you should have your DTS files streamed as multichannel LPCM to your unit (capped @ 48Khz until I remove the limitation).

btw, 24 bit LPCM exists and is known as audio/L24 but AFAIK it is not part of DLNA profiles (I need to get more info on this). Every media server I've seen use audio/L16.

will zune service work with this? Right now all I can do is stream my zune collection through my xbox360.

I decoded some DTS flac files to wav and then renamed the extensions to dtswav. foobar is correctly recognizing them as DTS encoded wav files and now streams all 6 channels as LPCM to the Oppo with no white noise. Unfortunately it sounds like I am listening to the chipmunks as the pitch has gone way up (although the speed appears to be correct). So, getting closer but not quite there!

To respond to one of your earlier posts, the Oppo does not currently recognize wav files either so the only option is to transcode flac and wav files to LPCM.

I have read this entire thread a few times, looking for the "Apple" apps. My short list was, EyeConnect 1.6.6, TwonkyMedia Server 5.1.3, but I thought I would try the free PS3 Media Server, since a few Mac users, including "kwolfman" had some success with it. I briefly played with a just a few video files and will go back to video, but got STUCK with my first FLAC playback problems, any HELP is appreciated! Thanks.

APPLE MAC PLATFORM:

Using a Apple MacPro Dual-Core tower, 5 gigs of ram.
OS: Snow Leopard 10.6.3
Oppo BD83
Hardwired Ethernet cabled setup.

Just tried using PS3 Media Server 1.20.409 BETA

The Oppo can see all my hard drives, so far so good. But I can't play any FLAC files from my hard drives, I know the Oppo does NOT natively support FLAC playback, but I thought they would get "transcoded", but all I get is HISS playing, or nothing. Soon as I get time, I'll join the PMS forum, but since a rare few Mac users are here, and some are using this free PS3 Media Server with their Oppo, thought I would see if there are any Oppo specific settings to get this to work? Or any setting tips for the PMS program?

I normally have my Oppo set to Bitstream for HDMI Output, but I also tried selecting "auto", but that did not work, and then tried "PCM", none of these settings made a difference.

When I navigate to a folder with FLAC music files, I see two choices on my Oppo "network" screen for the audio files.

PCM ICON: "Song_Title.flac - MPlayer Audio" (this plays back HISS only)

MPEG ICON: "Song_Title.flac - Audio High Fidelity" (when I hit play, the Oppo goes into STOP mode, and nothing)

I have also added the Oppo "Player Profile" as per instructions here (first post in this thread):

http://www.avsforum.com/avs-vb/showt...e#post17886659

2nd to last line in this "Renderer Profile", lists FLAC:
"TranscodeExtensions=hdmov,hdm,flac,fla,dts,ogg,asf,asx,m2v,m 4a,mov,mp4,iso,avi"

I'm STUCK!

Streaming of 5.1 audio is currently not functional with the Oppo. You might try dropping it into a MKV/MKA container as LPCM. Not sure if that works or not, but others have reported it does.

Thanks for the tip. I did seem to recall earlier comments about 5.1 streaming. I haven't attempted audio or video via MKV yet. Been trying to nail the audio down first as that is my primary focus but will start looking into MKV in the near future.

As noted by rdgrimes, the OPPO probably do not support 5.1 LPCM and just plays it as stereo LPCM which would have the effect you describe. Which after checking would be in line that the fact that the DLNA LPCM profile is max 48Hkz / stereo. That doesn't mean a device could not play higher speced LPCM, but it is beyond strict DLNA specs. Sometimes I wonder what people who designed DLNA were smoking, with arbitrary limitations as this one, uneeded complexity, and no support for a free codec (such as FLAC)...

EDIT: so your best bet is to encode your DTS audio into a MKV/MKA. foo_upnp should be able to stream these files unmodified. If you want to play them in foobar2000, you'll need the input matroska plugin (as well as the foo_input_dts DSP as first element of the DSP chain).

I think it might possibly be a problem caused by the reference frames in the stream being <4, this is a confirmed issue with the LG which AFAIK uses the same chipset as the Oppo.

Another obvious and likely cause is it just can handle the full rates over a network stream. I would get hard locks with some DVD rips previously.

My pcs are fine playing these files on the same wired network too so it is defnitely an Oppo issue.

Eiredale, I can confirm that behavior you experience. Greater bandwidth thresholds over DLNA cause the Oppo to stutter. I'm using a PowerLine network connection and have confirmed it's not a bandwidth limitation.

I'm streaming ~10GB sized mkv's of Blu-ray rips with no stutters over LAN. While my switch and network is Gigabit, the Oppo itself isn't. I do have issues with stuttering when transcoding from the PC as the bitrate increases going from x264 to mpeg.

I'm using PS3 Media Server with Windows 7 Professional x64 on a Core i7 860 system.

That's interesting, I'll have to do testing with more MKVs (the one I tested was 8.44GB).

Followup: I tried the same file again, this time copied over to the machine that is running Tversity. 10 minutes in and there was perhaps one hiccup (unlike the much worse experience I had previously when streaming from a network share aka a wired 2006 Compaq laptop, my bad!). I'll have to try it with more files but it appears I've found the preliminary solution to my stuttering problem in any case.

I'm making progress.......

My new Linux NAS running MediaTomb seems much more stable with full rate files. 10 Minutes into a full rate rip now, not even a single stutter.

Edit: Hard locked in the same place as the old firmware. I think it might be because it has full rate DTS, will try some others.

Hi Tim,

If you're having a problem using J. River Media Center, we'd like to hear more details because I'm sure we could get it working for you.

Thanks.

I would be very happy to provide more details and attempt to get it working but apparently my 30 day trial period just expired so I can no longer run the software and won't purchase a license until I know I can use it successfully.

That said, from memory, one of the issues I had was the inability for the program to transition from one track to the next. It just froze up at the end of each track, requiring me to manually select and start the next track (very annoying to say the least). It also never correctly displayed the total track length for any tracks. It just displayed the same static number that didn't correlate with anything to my knowledge. I don't recall whether or not I had any file navigation issues when trying to browse by folder structure.

Not necessarily an issue but I also was never able to confirm whether or not JRMC was actually streaming full 24 bit data for flac or wav files that are transcoded to LPCM (since the Oppo doesn't natively support either flac or wav files). In an earlier post in this thread, Jim seemed to indicate that it was doing so but a few other people have indicated that it is not possible to stream 24 bit LPCM data via DLNA. I checked the JRMC log files but they don't indicate what transcoding is taking place and I have no other means to independently verify what bit depth and sample rate is being received by the Oppo.

Thanks for any assistance you can provide. I would be more than happy to help further but not sure what I can do since the program has timed out.

Can someone please confirm what The General is hearing/seeing via Asset UPnP?

Thanks,

Styln

Read the first post of this thread...

Yep, I've read it. In fact, I'm quoted in it.

Just looking for independent confirmation since it was brought up here that DLNA does not support 24 bit streaming. Understand that Asset is UPnP vs DLNA based. But of course, both the server and client need to support an option for it to implemented. I've seen many instances where options were negotiated to the lowest common denominator. Sure you have, too.

I've sent an email to Oppo to see if the player will use the full 24 bits of a stream or if its truncated to 16 bits. Not sure what to expect since it's not officially supported. I'll also do some listening tests this weekend. Might even setup wireshark just to see what goes by.

Overall, this is very encouraging.

Per usual fast email confirmation from Oppo customer support:

"Styln,

We can confirm that BDP-83 can play a full stereo 24/96 LPCM stream from a DLNA server.

I wonder if the Info mode will provide bit-rate confirmation for streamed content? Will try it tonight. In any case, it does look like Asset to Oppo supports 24/96 bit stereo streaming

Styln

Actually, it supports 24/192 just as well.

I purchased a BDP-83 and tried it with PBS capture in 99.22... unfortunately, I had no luck with it; when I selected that option, the player either locked up or bumped me back to the DLNA server selection screen.

I know the Oppo can play a stream like this... I tried a uPnP server called Jamcast, and it has a feature called "Virtual Soundcard" that sends via LPCM the output of the soundcard to the DLNA client.

The Oppo, as others have observed in this thread, can play tracks from the media library.

Let me know what I can do to help with PBS capture...

The Oppo , BTW, does not currently function as a Media Renderer.

Okay... more silly questions.

I have beens speaking with Oppo recently... The tech doesn't think the BDP-83 will ever stream HD Audio from ann MKV file...

But he did tell me that it would be possible to store the precious DTS-HD data in an AVCHD file...

Has any one ever ripped a BD to this format and streamed it.... is it even possible?

I asked earlier... but is there a file format that will stream SD DVD to the BDP-83 that will allow for full menu features and chapters... I love the extras on my disks! Could I put separate mkvs in the main dvd titile folder and stream the extras that way?

I love Plex... but the upconverted SD DVD from the BDP-83 just looks better... IMO.

Thanks

I've heard good things about: http://multiavchd.deanbg.com/


MKV allows for menus and chapters, but OPPO does not support those features.

AVHCD might work for that, too. You need to become expert on it and report back to us.

-Bill

Sure, I would expect that. However, with an analog system I'll just have to take your word for it as I know of no way to validate the bit rate of streaming media

Styln

Does the above confirmation re: Asset and Oppo include high-resolution multichannel audio (LPCM)?

There is a known bug that MCH streaming content sounds odd - high pitched weirdness. This one is 100% confirmed by several of us on the thread.

Styln

I think I know why it doesn't work. Go to the Default streaming profile (provided you have not created an OPPO specific one), in the Decode to PCM section change the codec to "lpcm". I bet you have set it to "wav" which is the default, and since the specified codec is also used for PSC, that wouldn't work since the OPPO do not support WAV. After that, restart foobar200 and eventually the OPPO (in case it'd have cached the streaming URL which include the codec) and start to play PBS (while playing some files in foobar2000).
