^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
--protection_scheme <scheme>
|
|
|
|
Specify a protection scheme, 'cenc' or 'cbc1' or pattern-based protection
|
|
schemes 'cens' or 'cbcs'.
|
|
|
|
--crypt_byte_block
|
|
|
|
Specify the count of the encrypted blocks in the protection pattern, where
|
|
block is of size 16-bytes.
|
|
|
|
There are three common patterns (crypt_byte_block:skip_byte_block):
|
|
1:9 (default), 5:5, 10:0.
|
|
|
|
Apply to video streams with 'cbcs' and 'cens' protection schemes only;
|
|
ignored otherwise.
|
|
|
|
--skip_byte_block
|
|
|
|
Specify the count of the unencrypted blocks in the protection pattern.
|
|
|
|
Apply to video streams with 'cbcs' and 'cens' protection schemes only;
|
|

|
|
--vp9_subsample_encryption, --novp9_subsample_encryption

|
|
segments including the partial segment overlapping with the initial
|
|
'clear_lead' seconds are not encrypted, with all the following segments
|
|

|
|
first segment is not encrypted.
|
