Playing iTunes (m4a) files remotely from Media Server sound very distorted
« on: February 23, 2011, 11:02:24 pm »
I am trying to play my library from latest MC15 Server (Win7) to my Android (running latest Gizmo).  The primary library files are encoded in APE and play great remotely.  But, files imported into library from my iTunes purchases (m4a) sound horrible (very distorted, scratchy, barely recognize the song).  These same m4a files play great directly from the server.

To isolate the problem, I tried connecting a laptop with MC15 Client to the same server and the ape sound good but m4a files also sound terrible.  On the server, I tried converting the m4a to mp3 (and others) and the converted files also sound horrible.  

I have read many postings/wiki and installing CCCP both on server and client, no luck.  I have tried to change the settings in the media server settings to always convert or never convert, no luck.

I'm stumped and welcome any suggestions.

Which side is converting the file? 

When I have MC15 running as a client on my laptop (connecting to library on media center server), which side does the conversion from m4a (or ape) into mp3?  I am a bit confused on which settings I should be modifying (options in Media Network on client or server).

Please help me isolate where my problem is.  Thanks,

Did a bit more isolation work tonight (sure feel alone on this and am anxious for help from the experts).

I was able to change my laptop (Dell Intel WinXP) into a MC15 server.  I can use this system to convert m4a into mp3, flac, ape.  All these files sounded good both on the server and when played remotely to Android or to my other systems.

However, my main music library (Intel 64bit Win7) has problems converting m4a into anything else.  If I try to convert to flac it aborts before getting started (at 0%).  If I convert into mp3 it sounds horrible (very scratchy and acts as if gain is turned up across the spectrum).  I tried to convert to ape and the application locked up with exception.

I turned on logging in MC15, repeated the test, and got messages below.  I can see exception at end but I need help decoding what led up to this:

Could this be an issue with 64bit (although I thought everything was running as a 32bit application)?
Could this be an issue with CCCP (I just did a fresh install with all settings reset and it appeared well)?

Any other steps I can do to get some traction on this.  Still anxious to get this working.  There is a lot of music purchased from iTunes that my kids are anxious to play and Dad is currently letting them down  :'(.

Thanks,

Sorry I can't be of any help, all I can do is give you my own experience. I copied several m4a files from an iPod to my computer (w7x64) and I experienced the same as you are. After fighting it for several days I moved the files over to my XP SP3 x86 machine and converted them and they worked perfectly. I have no clue what causes the issue all I know is everything I tried in the x64 realm was a waste of time. After discovering that conversion worked on my old laptop I pulled all music from my iPod converted it and sold my iPod. I will never run into that problem again my phone makes a nice iPod replacement for music on the go.

When I have MC15 running as a client on my laptop (connecting to library on media center server), which side does the conversion from m4a (or ape) into mp3?  I am a bit confused on which settings I should be modifying (options in Media Network on client or server).

Please help me isolate where my problem is.  Thanks,

The server does the conversion.

Can you play the files on the server without problems? If yes, right-click the main display in standard view during playback and look for the "DirectShow filters" menu item. If it shows up what filters does it list? (You can copy graph info to clipboard and paste it to your reply.)

However, my main music library (Intel 64bit Win7) has problems converting m4a into anything else.  If I try to convert to flac it aborts before getting started (at 0%).  If I convert into mp3 it sounds horrible (very scratchy and acts as if gain is turned up across the spectrum).

If this happens on the server the problem must fixed before the server/client conversion can work.

The likely cause of the problem is this filter and its output format:

Filter [351fa3c]  'Microsoft DTV-DVD Audio Decoder'
0057221: 3468: Playback: 0xd8c DumpGraph:         CLSID: {E1F1A0B8-BEEE-490D-BA7C-066C40B5E2B9}
0057221: 3468: Playback: 0xd8c DumpGraph:         Host: c:\windows\syswow64\msmpeg2adec.dll

0057221: 3468: Playback: 0xd8c DisplayTypeEx: Connection type  M type MEDIATYPE_Audio  S type MEDIASUBTYPE_IEEE_FLOAT

If the output is transmitted to the encoder in the float format the conversion will not work.

I have my server configured to use the DC-Bass Source filter for m4a splitting and decoding (it is a combined splitter/decoder filter). I just tried playing aac/m4a files through a server/client connection. Without conversion I experienced various problems which were caused by the problems with DirectShow filters on the client (I tried a few filters combinations), but playing with conversion worked fine. I tried "uncompressed" and "MP3 high bandwidth". (In general I recommend using "uncompressed" if that doesn't cause bandwidth problems. Lossy to lossy transcoding may produce unnecessary encoding artifacts.)

To use DC-Bass Source you must have it installed and then set the m4a file type to use it. See the attached screenshot. The DC-Bass Source filter is available here: http://www.dsp-worx.de/?n=15

Did you find the "M4P and M4A" article on our wiki?

To JRiver: I wonder if the server should change the stream's bit format to max 24-bit integer (before the actual file format conversion) if the DirectShow decoder happens to output float.

Re: Playing iTunes (m4a) files remotely from Media Server sound very distorted
« Reply #8 on: February 25, 2011, 11:03:20 am »
I don't see the "DirectShow Filters".  Where on the main display did you want me to click?

I did find and try to follow the M4A wiki page.  This prompted the install of CCCP, but so far this has not helped (although I don't fully understand internals or best setup for CCCP yet).

I agree the server is the culprit and am suspecting issue with x64 or Win7.  It does play m4a fine.  I am focused now on just converting files and the resulting mp3 has very high distortion and gain.  The conversion from m4a into ape/flac will fail.  With logs similar to above.

The current file type option for m4a is associated with "Automatic" playback method.  I tried switching this to "J River Audio Engine (Using DirectShow filter)" and source filter is Automatic.   Same distortion to mp3 and failure to convert into ape.  Looking at the logs it is still using "MEDIASUBTYPE_IEEE_FLOAT". 

I need to get into work but this helped me find the playback decoding options.  I will try more in this area tonight (including DC-Bass filter). 

Thanks for the help!

Play an m4a file on the server. During playback, right-click the main display to open the menu. It will not show the "DirectShow Filters" item if MC uses the QuickTime playback engine, but otherwise you should see it.

However, I am pretty sure that the "Microsoft DTV-DVD Audio Decoder" filter is causing the problem.

To use the DC-Bass Source filter, download and install it (you probably need to be logged in with administrator rights) and configure the file type specific settings as in my screenshot above.

... and also when a standalone MC instance converts local files.

I was experiencing the same problem.  The DC-Bass Source filter referred to above was the answer for me.

This is what worked for me (all of these steps are to be done on the server, not the client):

  • Download and install the DC-Bass Source filter
  • Select Tools->Options
  • On the left-hand list of  option categories, choose "File Types"
  • On the list of file types in the right-hand pane, select "Audio->AAC Audio (m4a, aac)"
  • In the lower pane, from the "Playback Method" drop list, choose "j. River Audio Engine (using Direct Show filter)"
  • From the "Source Filter" drop list, choose "DC-Bass Source" (this will appear in the drop list if this filter is properly installed)
  • Click OK to dismiss the Options dialog

On my server, the "Other filters" drop list has selected "JRiver Bitrate Monitor filter", but I don't recall choosing that explicitly.  I think this is the default when the "JRiver Audio Engine" is chosen.  Also, I think it best to stop and restart the Library Server to ensure that the new filter configuration for AAC takes effect (though I am not sure that it is absolutely necessary).

Good luck and let us know whether this works for you (or anything else works, either).

Just posting my attachment as a linked image:



It illustrates the above mentioned "File Type" settings.

You guys are great!  I would not have found this without you.  The DC-Bass Source now allows me to convert from m4a into flac, ape, mp3 and play without distortion.  I can also remotely play from Android using Gizmo.

Sounds like a few others have run into this, but my searches didn't find this answer anywhere (hard topic to search).  I suggest putting a note on the wiki M4A page with reference to this solution. 

Thanks again!
