Message types used by avdevice_app_to_dev_control_message().

Variants

AV_APP_TO_DEV_NONE

Dummy message.

AV_APP_TO_DEV_WINDOW_SIZE

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

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

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

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

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

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

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

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

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

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

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.

Trait Implementations

impl Clone for AVAppToDevMessageType

fn clone(&self) -> AVAppToDevMessageType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AVAppToDevMessageType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for AVAppToDevMessageType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<AVAppToDevMessageType> for AVAppToDevMessageType

fn eq(&self, other: &AVAppToDevMessageType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
