Detailed Description

Defines an encoded frame. This can be used as-is, or can be subclassed to support different frame types.

Member Function Documentation

§ Decrypt()

MediaStatus shaka::media::EncodedFrame::Decrypt	(	const eme::Implementation *	implementation,
		uint8_t *	dest
	)		const

virtual

Attempts to decrypt the frame's data into the given buffer. This may not be supported for some frame types or some EME implementations. This is only used by the DefaultMediaPlayer.

Definition at line 143 of file frames.cc.

§ EstimateSize()

size_t shaka::media::EncodedFrame::EstimateSize ( ) const

overridevirtual

Estimates the size of this frame. This can be used to restrict the number of frames stored or to monitor/debug memory usage. This should only be used as an estimate and may not accurately measure the size.

Returns: The estimated size of the frame, in bytes.

Reimplemented from shaka::media::BaseFrame.

Reimplemented in shaka::media::ffmpeg::FFmpegEncodedFrame.

Definition at line 162 of file frames.cc.

Member Data Documentation

§ data

const uint8_t* const shaka::media::EncodedFrame::data

The buffer that contains the frame data. This may contain encrypted data.

Definition at line 244 of file frames.h.

§ data_size

const size_t shaka::media::EncodedFrame::data_size

The number of bytes in data.

Definition at line 247 of file frames.h.

§ encryption_info

const std::shared_ptr<eme::FrameEncryptionInfo> shaka::media::EncodedFrame::encryption_info

Contains info on how this frame is encrypted. If this is nullptr, this frame is clear.

Definition at line 259 of file frames.h.

§ timestamp_offset

const double shaka::media::EncodedFrame::timestamp_offset

The offset, in seconds, that the times in the frame should be adjusted when decoding.

Definition at line 253 of file frames.h.
