Streaming to Airport Express from VLC 1.1.0by fulldecent » Tue Jul 13, 2010 6:02 pm

Hello, I heard that the 1.1.0 release of VLC support streaming to Apple Airport Express and that there was a simplified interface to do this.Information appears to be sparse on this, so I started a stub wiki page at http://wiki.videolan.org/Airport_Express

If you could please explain this process to me, I will update this wiki page.

Thanks,WillfulldecentNew Cone

I am not aware of such functionality. The only approach that I know is to use a third party application.Providing logs, messages, configuration info (VLC, OS, Hardware) and a clear explanation of the issue always helps the problem solvershelp you, even if they don't end up solving the issue. Just think what you would need if you were solving someone else's problem.

This is discussed a bit in a few other threads.http://forum.videolan.org/viewtopic.php?f=14&t=62267http://forum.videolan.org/viewtopic.php?f=12&t=63324

From what I can tell, the easiest way to make it work is to go into preferences>all>stream outputthen, in the box for "default stream output chain", you typeCode: Select all#transcode{acodec=alac,channels=2,samplerate=44100}:raop{host=<ip address of airportexpress>,volume=175}

This will stream audio to the airport express. You must delete this when you want to normally play files on your computer.

If you want to stream audio to the airport express whenever you play media files, but also have them display on your computer screen (andhave audio through the computer speakers) you can instead typeCode: Select all

Page 3 sur 7https://forum.videolan.org/viewtopic.php?f=12&t=79400

#duplicate{dst="transcode{acodec=alac,channels=2,samplerate=44100}:raop{host=<ip address of airportexpress>,volume=175}",dst=display{delay=1000}}

where the "delay" value is in milliseconds and can be used to try and synchronize the video/sound from the computer with the airportexpress. If you don't want VLC to play sound out of your computer you can useCode: Select all#duplicate{dst="transcode{acodec=alac,channels=2,samplerate=44100}:raop{host=<ip address of airportexpress>,volume=175}",dst=display{no-audio,delay=1000}}

The ip address of the airport express can be found using the AirPort Utility. Usually it's of the form 10.0.1.x where x is between 1 and 254.

If you correctly set the values under the preferences for transcode, raop, and display (preferences>all>stream output>soutstream>*transcode/raop/display*) then you can use the short option ofCode: Select all#duplicate{dst="transcode:raop",dst=display}

to control generating streams to the airport and display.

Hope this helps.crzyhankoBlank Cone

Thanks crzyhanko, that was very helpful.

But the above doesn't work for me when the input audio stream only has one channel. When I try to play a video with a mono audio stream, Iget the following error message:stream_out_raop error: The Apple Lossless audio stream must be encoded with 44100 Hz and 2 channels

I am using #transcode{acodec=alac,channels=2,samplerate=44100} as above, but the single-channel input is not being converted to the two-channel output required by the raop module.

Does anyone know how to transcode a mono audio stream to a stereo audio stream? Is it even possible with VLC?

Here's a larger excerpt from my log messages:mpeg_audio debug: MPGA channels:1 samplerate:48000 bitrate:128stream_out_transcode debug: creating audio transcoding from fcc=`mpga' to fcc=`alac'stream_out_transcode debug: Looking for filter (mpga->s16l, channels 1->1, rate 48000->44100)mpgatofixed32 debug: mpga->f32l, bits per sample: 0bandlimited_resampler debug: f32l/48000KHz/1->f32l/44100KHz/1audio_format debug: f32l->s16l, bits per sample: 32->16stream_out_transcode debug: Got complete audio filter chainstream_out_raop error: The Apple Lossless audio stream must be encoded with 44100 Hz and 2 channelsgnippiksNew Cone

How can I do this?

I am using the transcode module with the channels=2 option, but that does not change the number of output channels to 2 if the input streamis mono. Thanks.gnippiksNew Cone

Sorry, no idea. I can't find anything that suggests a way to upmix. The only thought I have is maybe you could force something out of theheadphone surround effect, but I don't know enough about it to even begin to guess if that is actually doable.crzyhankoBlank Cone

Re: Streaming to Airport Express from VLC 1.1.0by chrisrp » Wed Nov 24, 2010 11:56 pm

Hi

With the help of this board i have managed to get my vlc to stream audio to my airport express! Thank you very much! I actually had to use:

Code: Select all#duplicate{dst=display{noaudio,delay=4000},dst="transcode{acodec=alac,channels=2,samplerate=44100}:raop{host=10.0.1.1,volume=175}"}

I switched the order of the commands, without switching the video delay wasn't working.

However i have another question. First let me say i have no knowledge of vlc command lines. But i would like to be able to control the volumefrom vlc and not the speakers. As it stands now the volume is fixed at whatever value is in the string.

Can anyone help me with this?

Thank you very much!

Thanks for these instructions - the abbreviated form with specific settings under each area works well for me, though I had to upgrade from1.0.5 to 1.1.11 before it would find the alac audio encoder.

thanks!nickdjonesNew Cone

Re: Streaming to Airport Express from VLC 1.1.0by mlte » Sat Jul 21, 2012 8:28 pm

Hi,Thanks for the tip, it almost works...but i'm having an issue using this code :#transcode{acodec=alac,channels=2,samplerate=44100}:raop{host=<ip address of airport express>,volume=175}

I have an orange triangle, which i think is due to the password i put for the airport connection. I guess there might be a code line where youcan add the password after the "host=<ip address of airport express>" part, but i have no idea of what it could be.

Anyone for an idea ?mlteNew Cone
