Initialize msg so that its contents are as if it was freshly allocated
with gst_sdp_message_new(). This function is mostly used to initialize a message
allocated on the stack. gst_sdp_message_uninit() undoes this operation.
When this function is invoked on newly allocated data (with malloc or on the stack), its contents should be set to 0 before calling this function.

Get the number of time information entries in msg.
Free all resources allocated in msg. msg should not be used anymore after
this function. This function should be used when msg was allocated on the
stack and initialized with gst_sdp_message_init().
Get the number of time zone information entries in msg.
Creates a uri from msg with the given scheme. The uri has the format:
`scheme:`///[#type=value *[&type=value]]
Where each value is url encoded.

msg.

the result #GstSDPMessage
Parse the null-terminated uri and store the result in msg.
The uri should be of the form:
scheme://[address[:ttl=ttl][:noa=noa]]/[sessionname] [#type=value *[&type=value]]
where value is url encoded. This looslely resembles http://tools.ietf.org/html/draft-fujikawa-sdp-url-01
