The above functions provide human-readable strings for media formats and decoder/demuxer/depayloader/encoder/muxer/payloader elements for use in error dialogs or other messages shown to users.

gst_pb_utils_add_codec_description_to_tag_list() is a utility function for demuxer and decoder elements to add audio/video codec tags from a given (fixed) GstCaps.

gst_pb_utils_get_source_description ()

gchar *
gst_pb_utils_get_source_description (const gchar *protocol);

Returns a localised string describing a source element handling the protocol specified in protocol , for use in error dialogs or other messages to be seen by the user. Should never return NULL unless protocol is invalid.

This function is mainly for internal use, applications would typically use gst_missing_plugin_message_get_description() to get a description of a missing feature from a missing-plugin message.

gst_pb_utils_get_sink_description ()

gchar *
gst_pb_utils_get_sink_description (const gchar *protocol);

Returns a localised string describing a sink element handling the protocol specified in protocol , for use in error dialogs or other messages to be seen by the user. Should never return NULL unless protocol is invalid.

This function is mainly for internal use, applications would typically use gst_missing_plugin_message_get_description() to get a description of a missing feature from a missing-plugin message.

gst_pb_utils_get_decoder_description ()

gchar *
gst_pb_utils_get_decoder_description (const GstCaps *caps);

Returns a localised string describing an decoder for the format specified in caps , for use in error dialogs or other messages to be seen by the user. Should never return NULL unless factory_name or caps are invalid.

This function is mainly for internal use, applications would typically use gst_missing_plugin_message_get_description() to get a description of a missing feature from a missing-plugin message.

gst_pb_utils_get_encoder_description ()

gchar *
gst_pb_utils_get_encoder_description (const GstCaps *caps);

Returns a localised string describing an encoder for the format specified in caps , for use in error dialogs or other messages to be seen by the user. Should never return NULL unless factory_name or caps are invalid.

This function is mainly for internal use, applications would typically use gst_missing_plugin_message_get_description() to get a description of a missing feature from a missing-plugin message.

gst_pb_utils_get_element_description ()

gchar *
gst_pb_utils_get_element_description (const gchar *factory_name);

Returns a localised string describing the given element, for use in error dialogs or other messages to be seen by the user. Should never return NULL unless factory_name is invalid.

This function is mainly for internal use, applications would typically use gst_missing_plugin_message_get_description() to get a description of a missing feature from a missing-plugin message.

gst_pb_utils_add_codec_description_to_tag_list ()

gboolean
gst_pb_utils_add_codec_description_to_tag_list
                               (GstTagList *taglist,
                                const gchar *codec_tag,
                                const GstCaps *caps);

Adds a codec tag describing the format specified by caps to taglist .

gst_pb_utils_get_codec_description ()

gchar *
gst_pb_utils_get_codec_description (const GstCaps *caps);

Returns a localised (as far as this is possible) string describing the media format specified in caps , for use in error dialogs or other messages to be seen by the user. Should never return NULL unless caps is invalid.
