isCustom

public boolean isCustom()

Gibt zurück:

whether @info was registered as a #GstCustomMeta with gst_meta_register_custom()

register

public MetaInfo register()

Registers a new meta.

Use the structure returned by gst_meta_info_new(), it consumes it and the
structure shouldnt be used after. The one returned by the function can be
kept.

Gibt zurück:

the registered meta

_new

public static MetaInfo _new(long api,
 @Nonnull
 Str impl,
 long size)

Creates a new structure that needs to be filled before being
registered. This structure should filled and then registered with
gst_meta_info_register().

Example:
```c
const GstMetaInfo *
gst_my_meta_get_info (void)
{
static const GstMetaInfo *meta_info = NULL;

if (g_once_init_enter ((GstMetaInfo **) & meta_info)) {
GstMetaInfo *info = gst_meta_info_new (
gst_my_meta_api_get_type (),
"GstMyMeta",
sizeof (GstMyMeta));
const GstMetaInfo *meta = NULL;

info->init_func = my_meta_init;
info->free_func = my_meta_free;
info->transform_func = my_meta_transform;
info->serialize_func = my_meta_serialize;
info->deserialize_func = my_meta_deserialize;
meta = gst_meta_info_register (info);
g_once_init_leave ((GstMetaInfo **) & meta_info, (GstMetaInfo *) meta);
}

return meta_info;
}
```

Parameter:

api - the type of the #GstMeta API

impl - the name of the #GstMeta implementation

size - the size of the #GstMeta structure

Gibt zurück:

a new #GstMetaInfo that needs to be filled
