Complex stream logger system

**StreamLogger project

**Solution for recording of various streams should be created. Stream

listing is in XML. Solution should run unattended, making provision for

every kind of error that could occur: disconnects, stream loss, etc.

StreamLogger will rip and save various kind of streams: shoutcast

audio, windows media audio, windows media video.? Along with that

project, there will be another one for delivering logged content back

to the users preserving streaming experience and giving additional

services.

## Deliverables

**Project detailed description

**I need to record streams from the radio stations listed in an XML file.

Each radio station should have it's own directory for file storage, also

listed in XML file. Streams should be recorded continuously, so no

second of audio is lost if the server is transmitting continuously.

**Features**

* for every stream, logger should save stream data to the hard

disk

* stream data is saved to disk in its native format - that means

that for shoutcast there will be mp3 and aac files, and for

windows media audio there will be wma audio, and so forth

* operator should choose duration of each stream log, and

application should delete all files older then time of the archived

file expires

* for windows media streams that facilitate multiple bitrates, user

should be able to choose which bitrates to capture

* stream should be saved in files with fixed length which is

determined by the operator, for example, every 10 minutes new

output file should be created and stream saved to it

* files should be cut on fixed time in the hourly clock, for example

on 0, 15, 30 and 45 minute of the hour

* metadata changes should be logged separately to log file along

with exact time of metadata change

* error messages should be logged to the file separate from

metadata log, one file for each stream

* if the connection to the stream server is broken, application

should try to restore the connection as soon as possible

* when restoring connection, application should try to restore it as

soon as possible, and in case of repeated failure to connect,

program will increase the time of delay, allowing the server to

lift any bans that might be in effect

* application holds the list of streams in XML file that has

following properties:

* stream/station name

* stream URL

* list of streams that should be saved

* activity status

* last error time

* last disconnection reason

* type of file cutting

* time of file cutting

* duration of the archive

* total cumulative bitrate of all streams

* errror reporting flags

* each logger (stream) should monitor it's state and report any

problems with the logging

* application should be able to run 24/7 regardless of any network

or server condition that might arise

* any errors should be sent via e-mail so the operator should be

able to choose corrective action

* file extensions:

* for shoutcast: .mp3 for mpeg encoded streams,

or .aac for aacplus encoded streams

* for windows audio: .wma

* for windows video: .wmv

**Technical**

Application consists of following components:

* main shell (windows forms application)

* ripping components for every particular stream format

* file cutter algorithm component

* stream ripper monitor component

**Platform**

* Software should run on Windows XP or Windows Server systems.

* application should be developed with visual studio 2005

* .net version 2.0 should be used

* for windows media, windows format sdk should be used

([url removed, login to view])

* for shoutcast, low socket communication will be sufficient

* sources should be maintained on subversion repository

**Existing code

**There is proof-of-concept code that runs good for shoutcast streams,

and rather well for .wma streams.? Both projects are available and

should be preferably built further.

**Testing**

I will provide testing, but in order to fully test it in 24/7 conditions,

please allow some time before each test iteration (few days).

Coder could have TightVNC access to the machine on which logger

will be run 24/7 for purpose of testing, allowing him to run any version.

Mantis bugtracker will be used for maintaining defect and issue list.

I will provide listing of streams that should be handled, and project

will be completed when every stream from that list will be handled

properly.

**Partial delivery**

I will accept bids on partial solutions, for example I will accept one

bid for shoutcast, second for windows media.? In that case, coder

should be able to work on same codebase with other coder.
