Message types used by avdevice_app_to_dev_control_message().

Variants

AV_APP_TO_DEV_NONE = 1_313_820_229

Dummy message.

AV_APP_TO_DEV_WINDOW_SIZE = 1_195_724_621

Window size change message.

Message is sent to the device every time the application changes the size of the window device renders to. Message should also be sent right after window is created.

data: AVDeviceRect: new window size.

AV_APP_TO_DEV_WINDOW_REPAINT = 1_380_274_241

Repaint request message.

Message is sent to the device when window has to be repainted.

data: AVDeviceRect: area required to be repainted. NULL: whole area is required to be repainted.

AV_APP_TO_DEV_PAUSE = 1_346_458_912

Request pause/play.

Application requests pause/unpause playback. Mostly usable with devices that have internal buffer. By default devices are not paused.

data: NULL

AV_APP_TO_DEV_PLAY = 1_347_174_745

Request pause/play.

Application requests pause/unpause playback. Mostly usable with devices that have internal buffer. By default devices are not paused.

data: NULL

AV_APP_TO_DEV_TOGGLE_PAUSE = 1_346_458_964

Request pause/play.

Application requests pause/unpause playback. Mostly usable with devices that have internal buffer. By default devices are not paused.

data: NULL

AV_APP_TO_DEV_SET_VOLUME = 1_398_165_324

Volume control message.

Set volume level. It may be device-dependent if volume is changed per stream or system wide. Per stream volume change is expected when possible.

data: double: new volume with range of 0.0 - 1.0.

AV_APP_TO_DEV_MUTE = 541_939_028

Mute control messages.

Change mute state. It may be device-dependent if mute status is changed per stream or system wide. Per stream mute status change is expected when possible.

data: NULL.

AV_APP_TO_DEV_UNMUTE = 1_431_131_476

Mute control messages.

Change mute state. It may be device-dependent if mute status is changed per stream or system wide. Per stream mute status change is expected when possible.

data: NULL.

AV_APP_TO_DEV_TOGGLE_MUTE = 1_414_354_260

Mute control messages.

Change mute state. It may be device-dependent if mute status is changed per stream or system wide. Per stream mute status change is expected when possible.

data: NULL.

AV_APP_TO_DEV_GET_VOLUME = 1_196_838_732

Get volume/mute messages.

Force the device to send AV_DEV_TO_APP_VOLUME_LEVEL_CHANGED or AV_DEV_TO_APP_MUTE_STATE_CHANGED command respectively.

data: NULL.

AV_APP_TO_DEV_GET_MUTE = 1_196_250_452

Get volume/mute messages.

Force the device to send AV_DEV_TO_APP_VOLUME_LEVEL_CHANGED or AV_DEV_TO_APP_MUTE_STATE_CHANGED command respectively.

data: NULL.
