GstTag.TagDemuxClass¶

Fields¶

Name	Type	Access	Description
identify_tag	`object`	r	identify tag and determine the size required to parse the tag. Buffer may be larger than the specified minimum size. Subclassed MUST override this vfunc in their class_init function.
merge_tags	`object`	r	merge start and end tags. Subclasses may want to override this vfunc to allow prioritising of start or end tag according to user preference. Note that both start_tags and end_tags may be `None`. By default start tags are preferred over end tags.
min_end_size	`int`	r	minimum size required to identify a tag at the end and determine its total size. Set to 0 if not interested in end tags. Subclasses should set this in their class_init function.
min_start_size	`int`	r	minimum size required to identify a tag at the start and determine its total size. Set to 0 if not interested in start tags. Subclasses should set this in their class_init function.
parent_class	`Gst.ElementClass`	r	the parent class.
parse_tag	`object`	r	parse the tag. Buffer will be exactly of the size determined by the identify_tag vfunc before. The parse_tag vfunc may change the size stored in *tag_size and return `GstTag.TagDemuxResult.AGAIN` to request a larger or smaller buffer. It is also permitted to adjust the tag_size to a smaller value and then return `GstTag.TagDemuxResult.OK` in one go. Subclassed MUST override the parse_tag vfunc in their class_init function.
reserved	[`object`]	r

None
