My application is generating a PCM audio buffer and I'd like a way to use libvlc to stream the audio out over http. I have figured out all of the pieces, except how to actually send the raw audio data to libvlc. From my searching I have seen references to using imem for this, but I don't see any examples of how to send chunks of the audio at a time.

Any assistance?

As best as I can tell I'm looking at an options string of:

"--imem-cat 1 --imem-get=my_audio_get_function --imem-release=my_audio_release_function --imem-data=pointer_to_data --imem-cookie=the_cookie"

Since I'm passing in audio, imem-cat should be the value 1. From here it seems to me that I have to implement a get function, and a release function. Then the two functions will be passed the pointer, and the cookie. I have yet to figure out what the cookie is for, but if I under stand the other pieces correctly I think I'm getting closer.

I realize I will probably need to set the codec, channels and samplerate as well, but that seems simple enough.

The cookie is useless in your use case. Ignore it.

can you provide more details about imem?

i do not understand how to use it.
