Media Tool
Multimedia

The Media Tool APIs provides functions for AV packet buffer for interworking between mutimedia framework module .

Required Header

#include <media_packet.h>

Overview

MEDIA TOOL API allows :

  • Create media_packet handle and Allocate buffer to heap or tbm_surface
  • Set and Get metadata of media packet

The media packet handle is created by caller. After creating media_packet_h handle, the caller can set & get other meta datas.
