correctSSRC

public static long correctSSRC(long ssrc)

Converts an number represented as a signed integer(32 bits) to a long integer (64 bits). JMF methods return the SSRC as an integer. As SSRC is a 32 bits number, some are represented in JMF as negative integers. This convertion is necessary to present SSRCs as a positive integer.
