I am setting my audio output to waveOut. The sound quality is poor. It is often choppy and garbled in places. I am playing an mp3 file. I have also tried using the vlc command line to convert the mp3 file to a muLaw wav file and its sound quality is equally as poor. Any suggestions? muLaw conversion...

Update: I have tried using vlc to convert my file to muLaw then playing in through the UI and it sounds equally as bad in waveout. muLaw conversion: vlc C:\temp\audio.mp3 :sout=#transcode{vcodec=none,vb=0,scale=0,acodec=mlaw,ab=16,channels=1,samplerate=32000}:standard{access=file,dst=audio.wav} vlc:...

I am using libvlc in an application that runs as a service. It plays mp3 files among other formats. I am using waveout because it does not require a desktop (an active session / logon). That is a requirement. However the sound quality playing an mp3 file is poor. It is often choppy and garbled in pl...

If you already know the second file at the start of your process, you can use a media list player. That would probably be easier than the event handler route.

Got it! Since there are other posts about this and none of them were really resolved, here is what I did to get things to work. 1) I set the second parameter to libvlc_audio_output_device_set() should be "waveout" and not the audio device name. I think I saw others make that mistake. VLC c...

Are there any work arounds?

I need the ability to play audio in a service in a non-interactive (logged out) session and switch the audio output device on the fly.

Since I have more than one version of vlc on my machine, I tried the following. const char * const vlc_args[] = {"--ignore-config", "--plugin-path=C:\\MyPath\\VideoLAN\\VLC\\2.0.0\\vlc\\plugins",}; vlcInstance = libvlc_new (sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args); and m...

I am trying to use the libvlc api in Windows7 to specify the audio device to output to. This command works from the command line C:\Temp>"C:\Program Files (x86)\VideoLAn\vlc\vlc" --waveout-audio-device="Speakers (High Definition Audio ($1,$ffff)" poker_music.mp3 I can get it to w...

Thanks for the quick reply!

It looks like our best option is to use libVlc from VLC 2.0 by including the header files in a project similar to this one

We are looking at using VLC in a commercial app but I am not entirely sure about the restrictions that would be placed on us since we would not want to extend the GPL or LPGL license to our products at least not to all of our programs. One option for us would be for us to use libVLC in C++. It looks...

I have programs using VLC libraries that do 2 things. Both are working fine. 1) Transcode a wav file to muLaw and send a multicast stream to an ipaddress and port using rtp. The ipaddress sent to is a decoder. 2) Play a stream using http/ipaddress/path/filename.sdp where ipaddress is an encoder stre...

I believe the problem is that I am trying to play a muLaw stream and the support for this is poor. If I change my output stream to mp3, then the second VLC instance plays audio. But I need VLC to play a stream from an encoder device that outputs muLaw / G.711 PCM. Any suggestions how I can make this...

To be more clear, including the '@' or not including it doesn't make a difference. It does not work either way.

It works the same way with or without the '@'.
Removing the extraneous video options doesn't make a difference either.

I am having a hard time streaming with the following commands. I could be dealing with network issues but before I go push that department for help, I would like to know if what I am doing should work. vlc temp.wav :sout=#transcode{vcodec=none,vb=0,scale=0,acodec=mlaw,ab=16,channels=1,samplerate=320...

Did you ever figure out this problem. I am having the same problem. I was disappointed to see that the only replies you got were from people criticizing typos.
