STRUCTS

AudioFormat

Defined in fuchsia.mediastreams/audio_format.fidl

Describes a format used for audio elementary streams without reference to compression. Where compression is supported, this type should be combined with a Compression struct.

FieldTypeDescriptionDefault
sample_format AudioSampleFormat

The type of individual samples.

 No default
channel_count uint32

The number of samples per frame.

 No default
frames_per_second uint32

The number of frames per second.

 No default
channel_layout AudioChannelLayout

The spatial assignment of each channel.

 No default

Compression

Defined in fuchsia.mediastreams/compression.fidl

Describes the compression applied to a stream.

Removed: HEAD

FieldTypeDescriptionDefault
type CompressionType

The type of compression applied to the stream.

 No default
parameters vector<uint8>?

Opaque 'out-of-band' parameters describing the compression of the stream.

 No default

Encryption

FieldTypeDescriptionDefault
scheme EncryptionScheme No default
default_key_id EncryptionKeyId No default
default_init_vector EncryptionInitVector No default
default_pattern EncryptionPattern? No default

EncryptionPattern

Defined in fuchsia.mediastreams/encryption.fidl

FieldTypeDescriptionDefault
clear_blocks uint32 No default

EncryptionSubsampleEntry

Defined in fuchsia.mediastreams/encryption.fidl

FieldTypeDescriptionDefault
clear_bytes uint32 No default
encrypted_bytes uint32 No default

VideoFormat

Defined in fuchsia.mediastreams/video_format.fidl

Describes a format used for video elementary streams without reference to compression. Where compression is supported, this type should be combined with a Compression struct.

Removed: HEAD

FieldTypeDescriptionDefault
pixel_format PixelFormat

Describes the manner in which pixels are encoded.

 No default
pixel_format_modifier uint64

Vendor-specific pixel format modifier.

 No default
color_space ColorSpace

Indicates the color space used to interpret pixel values.

 No default
coded_size fuchsia.math/Size

The size of a frame in terms of the number of pixels that are represented in a frame payload.

 No default
display_size fuchsia.math/Size

The size of a frame in terms of the number of pixels that should be displayed. These values will always be less than or equal to the corresponding coded_size values.

 No default
aspect_ratio fuchsia.math/Size?

Aspect ratio of a single pixel as the video is intended to be displayed.

 No default
