HDCP encryption/decryption

[prg.amc]

Hi, is anybody done HDCP encryption/decryption using mpegts. I haven't seen
any patches to support it. so I`ve updated mpegts mux and demux to support
HDCP. so just want to check if nobody added HDCP support I`llplan to push my
modifications.

No one do. Though I'm a bit surprised of this, since HDCP rules are very strict
and userspace isn't allowed to be involved in that (HDCP keys in force are not
allowed to be stored in clear). That's why it's usually burried/hidden in HDMI
HW.

Hi, Thanks for the information and your quick reply.

if applications take care of securing keys (eg: running in a safe memory zone) is it worth pushing changes to repo?.
