GstRTPPayloadInfo

The GstRTPPayloads helper functions makes it easy to deal with static and dynamic payloads. Its main purpose is to retrieve properties such as the default clock-rate and get session bandwidth information.

GstRTPPayloadInfo

Structure holding default payload type information.

Members

payload_type (guint8) –

payload type, -1 means dynamic

media (const gchar *) –

the media type(s), usually "audio", "video", "application", "text", "message".

encoding_name (const gchar *) –

the encoding name of pt

clock_rate (guint) –

default clock rate, 0 = unknown/variable

encoding_parameters (const gchar *) –

encoding parameters. For audio this is the number of channels. NULL = not applicable.

bitrate (guint) –

the bitrate of the media. 0 = unknown/variable.


GstRtp.RTPPayloadInfo

Structure holding default payload type information.

Members

payload_type (Number) –

payload type, -1 means dynamic

media (String) –

the media type(s), usually "audio", "video", "application", "text", "message".

encoding_name (String) –

the encoding name of pt

clock_rate (Number) –

default clock rate, 0 = unknown/variable

encoding_parameters (String) –

encoding parameters. For audio this is the number of channels. NULL = not applicable.

bitrate (Number) –

the bitrate of the media. 0 = unknown/variable.


GstRtp.RTPPayloadInfo

Structure holding default payload type information.

Members

payload_type (int) –

payload type, -1 means dynamic

media (str) –

the media type(s), usually "audio", "video", "application", "text", "message".

encoding_name (str) –

the encoding name of pt

clock_rate (int) –

default clock rate, 0 = unknown/variable

encoding_parameters (str) –

encoding parameters. For audio this is the number of channels. NULL = not applicable.

bitrate (int) –

the bitrate of the media. 0 = unknown/variable.


Functions

gst_rtp_payload_info_for_name

const GstRTPPayloadInfo *
gst_rtp_payload_info_for_name (const gchar * media,
                               const gchar * encoding_name)

Get the GstRTPPayloadInfo for media and encoding_name. This function is mostly used to get the default clock-rate and bandwidth for dynamic payload types specified with media and encoding name.

The search for encoding_name will be performed in a case insensitive way.

Parameters:

media

the media to find

encoding_name

the encoding name to find

Returns

a GstRTPPayloadInfo or NULL when no info could be found.


GstRtp.RTPPayloadInfo.prototype.for_name

    // javascript wrapper for 'gst_rtp_payload_info_for_name'
}

Get the GstRtp.RTPPayloadInfo for media and encoding_name. This function is mostly used to get the default clock-rate and bandwidth for dynamic payload types specified with media and encoding name.

The search for encoding_name will be performed in a case insensitive way.

Parameters:

media ( String ) –

the media to find

encoding_name ( String ) –

the encoding name to find

Returns ( GstRtp.RTPPayloadInfo ) –

a GstRtp.RTPPayloadInfo or NULL when no info could be found.


GstRtp.RTPPayloadInfo.for_name

def GstRtp.RTPPayloadInfo.for_name (media, encoding_name):
    #python wrapper for 'gst_rtp_payload_info_for_name'

Get the GstRtp.RTPPayloadInfo for media and encoding_name. This function is mostly used to get the default clock-rate and bandwidth for dynamic payload types specified with media and encoding name.

The search for encoding_name will be performed in a case insensitive way.

Parameters:

media ( str ) –

the media to find

encoding_name ( str ) –

the encoding name to find

Returns ( GstRtp.RTPPayloadInfo ) –

a GstRtp.RTPPayloadInfo or NULL when no info could be found.


gst_rtp_payload_info_for_pt

const GstRTPPayloadInfo *
gst_rtp_payload_info_for_pt (guint8 payload_type)

Get the GstRTPPayloadInfo for payload_type. This function is mostly used to get the default clock-rate and bandwidth for static payload types specified with payload_type.

Parameters:

payload_type

the payload_type to find

Returns

a GstRTPPayloadInfo or NULL when no info could be found.


GstRtp.RTPPayloadInfo.prototype.for_pt

function GstRtp.RTPPayloadInfo.prototype.for_pt(payload_type: Number): {
    // javascript wrapper for 'gst_rtp_payload_info_for_pt'
}

Get the GstRtp.RTPPayloadInfo for payload_type. This function is mostly used to get the default clock-rate and bandwidth for static payload types specified with payload_type.

Parameters:

payload_type ( Number ) –

the payload_type to find

Returns ( GstRtp.RTPPayloadInfo ) –

a GstRtp.RTPPayloadInfo or NULL when no info could be found.


GstRtp.RTPPayloadInfo.for_pt

def GstRtp.RTPPayloadInfo.for_pt (payload_type):
    #python wrapper for 'gst_rtp_payload_info_for_pt'

Get the GstRtp.RTPPayloadInfo for payload_type. This function is mostly used to get the default clock-rate and bandwidth for static payload types specified with payload_type.

Parameters:

payload_type ( int ) –

the payload_type to find

Returns ( GstRtp.RTPPayloadInfo ) –

a GstRtp.RTPPayloadInfo or NULL when no info could be found.


Function Macros
