Details¶

GstSdp.sdp_address_is_multicast(nettype, addrtype, addr)[source]¶

Parameters:	nettype (`str`) – a network type addrtype (`str`) – an address type addr (`str`) – an address
Returns:	`True` when addr is multicast.
Return type:	`bool`

Check if the given addr is a multicast address.

GstSdp.sdp_make_keymgmt(uri, base64)[source]¶

Parameters:	uri (`str`) – a `str` URI base64 (`str`) – a `str` base64-encoded key data
Returns:	a `str` key-mgmt data,
Return type:	`str`

Makes key management data

New in version 1.8.

GstSdp.sdp_media_new()[source]¶

Returns:

a GstSdp.SDPResult.

media:	pointer to new `GstSdp.SDPMedia`

Return type: (GstSdp.SDPResult, media: GstSdp.SDPMedia)

Allocate a new GstSdp.SDPMedia and store the result in media.

GstSdp.sdp_media_set_media_from_caps(caps, media)[source]¶

Parameters:	caps (`Gst.Caps`) – a `Gst.Caps` media (`GstSdp.SDPMedia`) – a `GstSdp.SDPMedia`
Returns:	a `GstSdp.SDPResult`.
Return type:	`GstSdp.SDPResult`

Mapping of caps to SDP fields:

a=rtpmap:(payload) (encoding_name) or (clock_rate)[or (encoding_params)]

a=framesize:(payload) (width)-(height)

a=fmtp:(payload) (param)[=(value)];…

a=rtcp-fb:(payload) (param1) [param2]…

a=extmap:(id)[/direction] (extensionname) (extensionattributes)

New in version 1.8.

GstSdp.sdp_message_as_uri(scheme, msg)[source]¶

Parameters:	scheme (`str`) – the uri scheme msg (`GstSdp.SDPMessage`) – the `GstSdp.SDPMessage`
Returns:	a uri for msg.
Return type:	`str`

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.

GstSdp.sdp_message_new()[source]¶

Returns:

a GstSdp.SDPResult.

msg:	pointer to new `GstSdp.SDPMessage`

Return type: (GstSdp.SDPResult, msg: GstSdp.SDPMessage)

Allocate a new GstSdp.SDPMessage and store the result in msg.

GstSdp.sdp_message_new_from_text(text)[source]¶

Parameters: text (str) – A dynamically allocated string representing the SDP description

Returns:

a GstSdp.SDPResult.

msg:	pointer to new `GstSdp.SDPMessage`

Return type: (GstSdp.SDPResult, msg: GstSdp.SDPMessage)

Parse text and create a new SDPMessage from these.

New in version 1.16.

GstSdp.sdp_message_parse_buffer(data, msg)[source]¶

Parameters:	data (`bytes`) – the start of the buffer msg (`GstSdp.SDPMessage`) – the result `GstSdp.SDPMessage`
Returns:	`GstSdp.SDPResult.OK` on success.
Return type:	`GstSdp.SDPResult`

Parse the contents of size bytes pointed to by data and store the result in msg.

GstSdp.sdp_message_parse_uri(uri, msg)[source]¶

Parameters:	uri (`str`) – the start of the uri msg (`GstSdp.SDPMessage`) – the result `GstSdp.SDPMessage`
Returns:	`GstSdp.SDPResult.OK` on success.
Return type:	`GstSdp.SDPResult`

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
