double shaka::media::EncryptionOptions::crypto_period_duration_in_seconds = 0

Crypto period duration in seconds. A positive value means key rotation is enabled, the key source must support key rotation in this case.

uint32_t shaka::media::EncryptionOptions::max_hd_pixels = 0

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, i.e. (max_sd_pixels, max_hd_pixels], it is HD.

Definition at line 35 of file encryption_handler.h.

uint32_t shaka::media::EncryptionOptions::max_sd_pixels = 0

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, i.e. [0, max_sd_pixels], it is SD.

uint32_t shaka::media::EncryptionOptions::max_uhd1_pixels = 0

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, i.e. (max_hd_pixels, max_uhd1_pixels], it is UHD1. Otherwise it is UHD2.
