These are the base descriptor types and methods.
For more details, refer to the ITU H.222.0 or ISO/IEC 13818-1 specifications and other specifications mentionned in the documentation.
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.
| descriptors | an array of GstMpegtsDescriptor. | [element-type GstMpegtsDescriptor][transfer none] | 
| tag | the tag to look for | 
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.
GstMpegtsDescriptor * gst_mpegts_descriptor_from_custom (guint8 tag,const guint8 *data,gsize length);
Creates a GstMpegtsDescriptor with custom tag
 and data
GstMpegtsDescriptor * gst_mpegts_descriptor_from_registration (const gchar *format_identifier,guint8 *additional_info,gsize additional_info_length);
Creates a GST_MTS_DESC_REGISTRATION GstMpegtsDescriptor
Return: GstMpegtsDescriptor, NULL on failure
gboolean gst_mpegts_descriptor_parse_iso_639_language (const GstMpegtsDescriptor *descriptor,GstMpegtsISO639LanguageDescriptor **res);
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.
gboolean gst_mpegts_descriptor_parse_iso_639_language_idx (const GstMpegtsDescriptor *descriptor,guint idx,gchar **lang,GstMpegtsIso639AudioType *audio_type);
Extracts the iso 639-2 language information from specific table id in 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.
| descriptor | ||
| idx | Table id of the language to parse | |
| lang | 4-byte gchar array to hold the language code. | [out][transfer full] | 
| audio_type | the GstMpegtsIso639AudioType to set. | [out][transfer none][allow-none] |

gboolean gst_mpegts_descriptor_parse_logical_channel (const GstMpegtsDescriptor *descriptor,GstMpegtsLogicalChannelDescriptor *res);
Extracts the logical channels from descriptor
.

Mpeg-TS descriptor (ISO/IEC 13818-1).
The type of GstMpegtsDescriptor
These values correspond to the registered descriptor type from the base MPEG-TS specifications (ITU H.222.0 | ISO/IEC 13818-1).
Consult the relevant specifications for more details.
The type of GstMpegtsDescriptor
These values correspond to miscellaneous descriptor types that are not yet identified from known specifications.
