Detailed Description

Muxer is responsible for taking elementary stream samples and producing media containers. An optional KeySource can be provided to Muxer to generate encrypted outputs.

Member Function Documentation

void shaka::media::Muxer::Cancel

(

)

Cancel a muxing job in progress. Will cause Run to exit with an error status of type CANCELLED.

Definition at line 90 of file muxer.cc.

void shaka::media::Muxer::set_clock ( base::Clock *  clock )

inline

Inject clock, mainly used for testing. The injected clock will be used to generate the creation time-stamp and modification time-stamp of the muxer output. If no clock is injected, the code uses base::Time::Now() to generate the time-stamps.

Parameters

clock

is the Clock to be injected.

void shaka::media::Muxer::SetKeySource	(	KeySource *	encryption_key_source,
		uint32_t	max_sd_pixels,
		uint32_t	max_hd_pixels,
		uint32_t	max_uhd1_pixels,
		double	clear_lead_in_seconds,
		double	crypto_period_duration_in_seconds,
		FourCC	protection_scheme
	)

Set encryption key source.

Parameters

encryption_key_source	points to the encryption key source. The caller retains ownership, and should not be NULL.
max_sd_pixels	specifies the threshold to determine whether a video track should be considered as SD. If the max pixels per frame is no higher than max_sd_pixels, it is SD.
max_hd_pixels	specifies the threshold to determine whether a video track should be considered as HD. If the max pixels per frame is higher than max_sd_pixels, but no higher than max_hd_pixels, it is HD.
max_uhd1_pixels	specifies the threshold to determine whether a video track should be considered as UHD1. If the max pixels per frame is higher than max_hd_pixels, but no higher than max_uhd1_pixels, it is UHD1. Otherwise it is UHD2.
clear_lead_in_seconds	specifies clear lead duration in seconds.
crypto_period_duration_in_seconds	specifies crypto period duration in seconds. A positive value means key rotation is enabled, the key source must support key rotation in this case.
protection_scheme	specifies the protection scheme: 'cenc', 'cens', 'cbc1', 'cbcs'.

void shaka::media::Muxer::SetProgressListener

(

std::unique_ptr< ProgressListener >

progress_listener

)
