gst_mpegts_find_descriptor ()

const GstMpegtsDescriptor *
gst_mpegts_find_descriptor (GPtrArray *descriptors,
                            guint8 tag);

Finds the first descriptor of type tag in the array.

Note: To look for descriptors that can be present more than once in an array of descriptors, iterate the GArray manually.

GPtrArray *
gst_mpegts_parse_descriptors (guint8 *buffer,
                              gsize buf_len);

Parses the descriptors present in buffer and returns them as an array.

Note: The data provided in buffer will not be copied.

gst_mpegts_descriptor_from_custom (guint8 tag,
                                   const guint8 *data,

Creates a GstMpegtsDescriptor with custom tag and data

                                gsize additional_info_length);

Creates a GST_MTS_DESC_REGISTRATION GstMpegtsDescriptor

Return: GstMpegtsDescriptor, NULL on failure

Extracts the iso 639-2 language information from descriptor .

Note: Use gst_tag_get_language_code if you want to get the the ISO 639-1 language code from the returned ISO 639-2 one.
