and null otherwise.
RTPBuffer.getExtensionData
glib.bytes.Bytes getExtensionData(out ushort bits)Similar to gst_rtp_buffer_get_extension_data, but more suitable for language bindings usage. bits will contain the extension 16 bits of custom data and the extension data (not including the extension header) is placed in a new #GBytes structure.
If rtp did not contain an extension, this function will return null, with bits unchanged. If there is an extension header but no extension data then an empty #GBytes will be returned.
Parameters
bits | location for header bits |
Returns
A new #GBytes if an extension header was present
