CastingCreateFromStreamMixer method

Previous pageReturn to chapter overviewNext page

Remarks

 

Creates a casting session that will output sound from the given stream mixer.

After creating the casting session, you can start it through the CastingStart method.

 

A casting session supports mono or stereo only so the stream mixer cannot be multi-channel.

 

Further information about management of casting sessions can be found inside the How to use the control as a source for streaming servers like SHOUTcast tutorial.

Parameter

Description

 

 

nStreamMixerID

Unique identifier of the stream mixer previously created through the StreamMixerCreate method.

strServer

Address of the cast server.

When connecting to a ShoutCAST Version 1 server or to an IceCast server, the address is in the format "address:port", for example "http://192.168.0.1:80"

When connecting to a ShoutCAST Version 2 server, which can manage more audio streams at the same time, the address is in the format "address:port,strid" where "strid" represents the identifier of the audio stream, for example "http://192.168.0.1:80,1234

strPassword

Password of the cast server

strIcecastMountName

Icecast mount name (for use with Icecast servers only)

nEncodeFormat

Encoding format

Supported values are the following:

Mnemonic constant

Value

Meaning

ENCODING_FORMAT_MP3

2

MP3 format

ENCODING_FORMAT_OGG

4

OGG Vorbis format

ENCODING_FORMAT_AAC_PLUS

22

AAC+ (HE-AAC)

strName

Stream name

strURL

URL of the radio station

strGenre

Genre of the stream

strHeaders

Additional headers to send to the server

strIcecastDescription

Further description for Icecast streams (for use with Icecast servers only)

nEncodeMode

Encode mode

Supported values are the following:

Mnemonic constant

Value

Meaning

CAST_ENCODE_QUALITY

0

Casting is based upon Quality

CAST_ENCODE_BITRATE

1

Casting is based upon Bitrate

fEncodeValue

Value related to the chosen encode mode (ignored when the nEncodeFormat parameter is set to ENCODING_FORMAT_AAC_PLUS):

if the value of the nEncodeMode parameter is set to CAST_ENCODE_QUALITY this parameter can assume the following range of values:

     - if the value of the nEncodeFormat parameter is set to ENCODING_FORMAT_MP3 can be from 0 (high quality but slow) to 9 (poor quality but faster)

     - if the value of the nEncodeFormat parameter is set to ENCODING_FORMAT_OGG can be from 0 (poor quality) to 10 (high quality)

if the value of the nEncodeMode parameter is set to CAST_ENCODE_BITRATE the passed value represents the bitrate in kbps (kilo bits per second)

nResampleFrequency

Resample frequency

nChannels

Number of channels

 

 

 

Return value

 

Value

Meaning

 

 

> 0

Numeric value representing the unique identifier of the casting session: this unique identifier will be used in order to invoke further methods related to the use of the casting session itself

Negative value
