Description (last modified by bennylp)
Framework to publish and consume media events in a media flow. The event framework can be used by any media types (audio and video) and any objects.
Overview of the framework (pjmedia/event.h):
typedef enum pjmedia_event_type { PJMEDIA_EVENT_NONE, PJMEDIA_EVENT_FMT_CHANGED, PJMEDIA_EVENT_WND_CLOSING, PJMEDIA_EVENT_WND_CLOSED, PJMEDIA_EVENT_WND_RESIZED, PJMEDIA_EVENT_MOUSE_BTN_DOWN, PJMEDIA_EVENT_KEY_FRAME_FOUND, PJMEDIA_EVENT_KEY_FRAME_MISSING, PJMEDIA_EVENT_USER = 100 } pjmedia_event_type; typedef struct pjmedia_event { pjmedia_event_type type; pj_timestamp timestamp; unsigned proc_cnt; const pjmedia_event_publisher *epub; union { pjmedia_event_fmt_changed_data fmt_changed; pjmedia_event_wnd_resized_data wnd_resized; pjmedia_event_wnd_closing_data wnd_closing; pjmedia_event_wnd_closed_data wnd_closed; pjmedia_event_mouse_btn_down_data mouse_btn_down; pjmedia_event_key_frame_found_data key_frm_found; pjmedia_event_key_frame_missing_data key_frm_missing; pjmedia_event_user_data user; void *ptr; } data; } pjmedia_event; typedef pj_status_t pjmedia_event_cb(pjmedia_event_subscription *esub, pjmedia_event *event); struct pjmedia_event_subscription { PJ_DECL_LIST_MEMBER(pjmedia_event_subscription); pjmedia_event_cb *cb; void *user_data; }; struct pjmedia_event_publisher { pjmedia_event_subscription subscription_list; }; PJ_DECL(void) pjmedia_event_init(pjmedia_event *event, pjmedia_event_type type, const pj_timestamp *ts, const pjmedia_event_publisher *epub); PJ_DECL(void) pjmedia_event_publisher_init(pjmedia_event_publisher *epub); PJ_DECL(void) pjmedia_event_subscription_init(pjmedia_event_subscription *esub, pjmedia_event_cb *cb, void *user_data); PJ_DECL(pj_status_t) pjmedia_event_subscribe(pjmedia_event_publisher *epub, pjmedia_event_subscription *esub); PJ_DECL(pj_status_t) pjmedia_event_unsubscribe(pjmedia_event_publisher *epub, pjmedia_event_subscription *esub); PJ_DECL(pj_status_t) pjmedia_event_publish(pjmedia_event_publisher *epub, pjmedia_event *event); PJ_DECL(pj_status_t) pjmedia_event_republish(pjmedia_event_publisher *esrc, pjmedia_event_publisher *epub, pjmedia_event_subscription *esub);
