[video_player] Orientation tag about plugins HOT 5 OPEN

we will check if there is such API to get rotation angle from MM player

from plugins.

Currently, video player plugin use texture method which use MMPlayer software codec(hardware codec is not supported for texture method), but software codec don't support that tag, and right now MMplayer don't provide such an API to get rotation information from metadata.
To solve this issue, there are two solution:

1. Use another video player which implemented based on video hole and plus player(to support local video file, we may need to support MMplayer). Hardware codec can support this video tag and rotate automatically, and video player don't need to do anything.
2. MMplayer provide an API to get rotation information, so that video plugin can change geometry of the texture.

but software codec don't support that tag, and right now MMplayer don't provide such an API to get rotation information from metadata.

Well, if you can read the rotation metadata from the video file, can you solve it by second way?
Here I attach some information those might helpful.

  metadata_extractor_h metadata_h;
  metadata_extractor_create(&metadata_h);
  metadata_extractor_set_path(metadata_h, video_file_path);

  char *value = nullptr;
  metadata_extractor_get_metadata(metadata_h, METADATA_ROTATE, &value);

we can get rotation value,but set to player, not effect.

I guess that this approach only works when the player uses the display feature.

error_code = player_set_display(g_player, PLAYER_DISPLAY_TYPE_OVERLAY, GET_DISPLAY(evas_obj));
