Please, before bidding, really understand what this is !
An iPhone application which can receive a Multicast stream (need to subscribe to the address, listen on the UDP port ..) of RTP encapsulated PCM audio.
In this first version, the multicast address is FIXED and the port number too.
For the received UDP blocks (containing RTP), the RTP header must be checked, stripped, and the samples must be played out to the audio interface.
A buffering algorithm (jitter buffer) uses a configurable buffer size in blocks/samples must be implemented, the description is under NDA. it is not complicated, but it needs to be fully understood and correctly implemented, as its own module (expected 50 lines of code, but technically precise implementation).
The description will be handed to the finalists before awarding the project.
The audio format for the playback is 24kHz PCM mono, as an alternative, if easier to implement, 22.05kHz could be an option.
The app must be optimized for low latency. PCM audio interface and its buffering on iOS needs to be fully understood.
Decoding a Stream from vlc on a linux box must be supported
The UI can be used for debug purposes in this first version. The only configurable parameter is the buffer size, that can be a simple field on the UI, and a restart of the software is OK if the buffer size is changed (default: 50ms, which is 1200 samples, 2400 Bytes).
The app is used for a technology demonstration.
Full source code is to be provided at the final stage of the project, so i can compile myself on Xcode.
If required, i do have a working source code fitting most of the requirements.
The project will be continued if the right freelancer is found, so, please, PM me with an estimate of hours and your hourly rate, i also would like to hear why you think you are the ideal resource, references if possible. If you need to quote more than the budget, let me know too and why. I would expect a seasoned experienced developer to spend no more than 8 hours on this, but that might be a wrong assumption.
Again - this is NOT a simple HTTP MP3 streaming receiver. If you do not understand RTP, RTP payload types, multicast, or low level audio interfaces on iOS - don't PM.
AND.. if you can do this on Android, please state so - that is an accepted alternative ... if you read to here, you are probably smart and interested, so you can state that you want to do it on Android :)

hello
I am good at voip protocols for example h323 sip
the rtp is used to transport audio and vedio data and rtsp is used to control the data transport
so I think I can handl your problem
also it is a messy work so I bid $500
please leave me message if you think I am ok
thanks
