'Audio Switcher::Out' in MPC 6484; VLC wins out here!

[ukb008]

Hi

One fine morning, I suddenly find that I can't play mp3 audio. I have Lame 3.97a10.

WMP10 says:

C00D11BA: Cannot play the file; Error ID = 0xC00D11BA, Condition ID = 0x00000000. Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly.

The mpeg2/mpeg4 (+mp3 vbr audio) video plays, but without sound.

PowewDVD plays mpeg2 perfect, sound and all, but mpeg4 (+mp3 vbr audio) with no sound.

MPC 6484 (the latest version) plays mpeg2 perfect, but mpeg4 (+mp3 vbr audio)without sound; it says:

Media Player Classic could not render some of the pins in the graph, you may not have the needed codecs or filters installed on the system.

The following pin(s) failed to find a connectable filter:

MPC error message window offers to look for codecs on the net. Clicking that produces:

Sorry, we couldn't find any codec with that guide in our database, the good news is that we will investigate your submission and probably add it later.

Well, what the devil is happening, PROs?

Edit 21 May 05:

VideoLAN player (http://fileforum.betanews.com/download/VLC_VideoLAN_for_Windows/1034861925/1) has no problems, though. Maybe because "it does not use directshow (no extra codecs required, runs on many platforms, many other advantages)", in the words of Kpex in one (http://forum.doom9.org/showthread.php?s=&threadid=94518) of his posts.

Lame is an encoder and not a directshow decoder.

Did you install a codec pack?
Your problems smells like "a codec pack messed up your system"

A Mp3 decoder comes with Windows.

A better MP3 decoder is Dcoder's MP3Source filter which can better handle "problematic" Mp3 files:

VLC isn't a DirectShow player. So you mix up apples with pears.

Thanks for your time, and the mp3source_v1.30.exe (http://www.dsp-worx.de/index.php?n=9).

Do I just install it, or I have to uninstall something first?

Yes, I was mixing apples with pears, perhaps because both are fruits and ought to taste good. When one doesn't, the mind says the other's better.

The MP3 Source Filter is a Filesource Filter that uses bass.dll 2.0 to decode MPEG Layer 3 Files. With it you're able to play MP3 Files from any DirectShow based Player, like Windows Media Player, Zoomplayer, MPC and TCMP.

The reason I build this Filter is because of the buggy MPEG-1 Splitter by Microsoft. Some MP3 files that contains Pictures within Id3v2 Tags, or wrong MPEG Headers caused by bugged Taggers caused that the AsyncSource Filter didn't connect to the MPEG1-Splitter. The MP3 Source Filter is able to play these files and since 1 Filter replaces 3, the Graphbuilding is much faster. The Filter renders only Files with the .mp3 Extension. MP3 Streams within other Containers (like AVI, MKV) are still decoded by the FhG Decoder. Installation

You can use the Installer Zip. This will install and uninstall the Filter automatically. Or, with the binary Archive, run register.bat to install the Filter and to uninstall the filter run unregister.bat and then delete the whole Folder.

it tells you everything what is important :) ...it will only concern pure .mp3 files not mp3 streams in videos, and it will only be used in DirectShow Players (not in VLC).

If you have installed a codec pack and didn't unistalled it or installed another over this pack, it will mess up your system and any DirectShow Player will have problems and 'll fail.

My posts inform this:

1. One fine morning, I see that my WMP's mp3-audio playing capability has gone away.
2. I am surprised (that's why I said one fine morning) because I haven't done anything to make it happen (like installing a codec pack).
3. If it were due to an absent ('messed up') codec, then probably MPC wouldn't have said, after searching in the net: Sorry, we couldn't find any codec with that guide in our database.

Your post tells me this:

1. mp3source will play standalone mp3 files, not the ones in video.
2. To play the mp3 audio in my mpeg4 files, I still need the Fraunhofer Gesellschaft mp3 decoder, and not the mp3source that you have mentioned.

Your post does not tell me:

What do I do?

So I'm afraid this conversation has been a waste of time for you. Sorry.

Okidoki.

MPC 6484 (the latest version) plays mpeg2 perfect, but mpeg4 (+mp3 vbr audio)without sound; it says:
Which audio renderer are you using (DirectSoundDevice/Wave OutDevice)?
Try to change it to see if it helps (you can do it easily in MPC (Playback/output).

Stream 1
AC3 Audio Decoder
Audio Switcher

Strange that a "AC3 audio decoder"-filter is trying to be build in the graph if you have a vbr mp3 stream in the file.

Normally the graph should look like:
Source (AVI)-->AVI Splitter-->Mp3 decoder-->audio renderer
-->video decoder-->video renderer

You can also try ffdshow for decoding mp3 inside a video (enable mp3 in the codecs list).

If that doesn't help I would install "Graphedit" to build your graph manually.


Good luck.

Thanks for your time again.

Changing audio rendered to each one present in MPC > View > Options > Playback > Output does not help.

I have installed ffdshow, enabling only mp3, but it does not help.

Graphedit says at forst that an audio hardware is missing. Building graph manually is a solution I didn't have the guts to try.

I'll go on using VLC in the meantime, untill that becomes mute, too. Let's see.

Hi.

This is to report that the audio problem has been solved just by reinstalling the audio from the motherboard CD. In these complex times of above-average technical prowesses (assumed or real) I had just forgotten to try this simple step. A chastening experience.
