Expand description

A set of commands that may be issued to an element providing the Navigation interface. The available commands can be queried via the gst_navigation_query_new_commands() query.

For convenience in handling DVD navigation, the MENU commands are aliased as: GST_NAVIGATION_COMMAND_DVD_MENU = Menu1 GST_NAVIGATION_COMMAND_DVD_TITLE_MENU = Menu2 GST_NAVIGATION_COMMAND_DVD_ROOT_MENU = Menu3 GST_NAVIGATION_COMMAND_DVD_SUBPICTURE_MENU = Menu4 GST_NAVIGATION_COMMAND_DVD_AUDIO_MENU = Menu5 GST_NAVIGATION_COMMAND_DVD_ANGLE_MENU = Menu6 GST_NAVIGATION_COMMAND_DVD_CHAPTER_MENU = Menu7

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Invalid

An invalid command entry

§

Menu1

Execute navigation menu command 1. For DVD, this enters the DVD root menu, or exits back to the title from the menu.

§

Menu2

Execute navigation menu command 2. For DVD, this jumps to the DVD title menu.

§

Menu3

Execute navigation menu command 3. For DVD, this jumps into the DVD root menu.

§

Menu4

Execute navigation menu command 4. For DVD, this jumps to the Subpicture menu.

§

Menu5

Execute navigation menu command 5. For DVD, the jumps to the audio menu.

§

Menu6

Execute navigation menu command 6. For DVD, this jumps to the angles menu.

§

Menu7

Execute navigation menu command 7. For DVD, this jumps to the chapter menu.

§

Left

Select the next button to the left in a menu, if such a button exists.

§

Right

Select the next button to the right in a menu, if such a button exists.

§

Up

Select the button above the current one in a menu, if such a button exists.

§

Down

Select the button below the current one in a menu, if such a button exists.

§

Activate

Activate (click) the currently selected button in a menu, if such a button exists.

§

PrevAngle
