Defines

LV_GSTREAMER_FACTORY_URI_DECODE
LV_GSTREAMER_PROPERTY_URI_DECODE
LV_GSTREAMER_FACTORY_FILE
LV_GSTREAMER_PROPERTY_FILE

Enums

enum lv_gstreamer_state_t

These sources are untested. For most of them, URI_DECODE can probably be used instead

Values:

enumerator LV_GSTREAMER_STATE_NULL
enumerator LV_GSTREAMER_STATE_READY
enumerator LV_GSTREAMER_STATE_PAUSED
enumerator LV_GSTREAMER_STATE_PLAYING

Functions

lv_obj_t *lv_gstreamer_create(lv_obj_t *parent)

Create a gstreamer object

Parameters:

parent – pointer to an object, it will be the parent of the new gstreamer

Returns:

pointer to the created gstreamer

lv_result_t lv_gstreamer_set_src(lv_obj_t *gstreamer, const char *factory_name, const char *property, const char *source)

Add a source to this gstreamer object

Parameters:

  • gstreamer – pointer to a gstreamer object

  • factory_name – the factory name for the source of this gstreamer object. for common factory names, check LV_GSTREAMER_FACTORY_XXX defines

  • property – the property name for the gstreamer source object for common properties, see LV_GSTREAMER_PROPERTY_XXX defines Passing NULL will create the source object but not set its source

  • source – the property value for the gstreamer source object Passing NULL will create the source object but not set its source

Returns:

LV_RESULT_OK if the source was correctly set else LV_RESULT_INVALID
