If the buffering time is too long, the user will repeatedly watch the same buffer advertisement repeatedly, which is easy to get bored. From a commercial point of view, repeated repetitions also waste valuable buffering advertising opportunities.
  • the current material file integrates multiple buffered advertisement contents, so when playing the material file in one buffer time, the user can view multiple buffered advertisement contents, but the playback order of the buffered advertisements in the material file is generated. It has been determined that this time each buffer During this period, playback can only start from the same buffered content, which may result in some ads never being played.
