Where I could called set custom frame encryptor and custom frame decryptor for webRTC in Blink RTC_Peer_Connection?

[Ivan Hutomo]

Hello everyone, I would to add a custom set frame encryptor inside a self-build electron. I already tried insertable streams but it was not working together with my modified webrtc for android. So here I already tried this custom encryptor in low-level webrtc and it's working. My problem now is how I could set my custom frame encryptor in higher-level code, so I could decide to set it from JavaScript.  I tried to add something here in the third_party/blink.

I tried to modify Peer_Connection_Interface.cc in webrtc/api/  :

Import my encryptor and decryptor 

#include "api/crypto/octon_frame_decryptor.h"

#include "api/crypto/octon_frame_encryptor.h"

and then add  my own function : 

rtc::scoped_refptr<PeerConnectionInterface>

PeerConnectionInterface::SetFrameEncryptor(std::vector<uint8_t>& new_keys) {

rtc::scoped_refptr<webrtc::OctonFrameEncryptor> encryptor_(

new webrtc::OctonFrameEncryptor(new_keys));

auto senders = GetSenders();

for (auto sender : senders) {

sender->SetFrameEncryptor(encryptor_);

}

return nullptr;

}

rtc::scoped_refptr<PeerConnectionInterface>

PeerConnectionInterface::SetFrameDecryptor(std::vector<uint8_t>& new_keys) {

rtc::scoped_refptr<webrtc::OctonFrameDecryptor> decryptor_(

new webrtc::OctonFrameDecryptor(new_keys));

auto receivers = GetReceivers();

for (auto receiver : receivers) {

receiver->SetFrameDecryptor(decryptor_);

}

return nullptr;

}

Now I have no idea how I could call this function from Blynk. Where and how to call SetFrameEncryptor and SetFrameDecryptor through RTC_Peer_Connection.cc? I am glad if anyone could give me suggestions. Thank you

Thank you everyone for helping
