Error undefined symbol: webrtc::FakeFrameEncryptor

[Ivan Hutomo]

Hi Wi, I tried to set a fake frame encryptor that using FrameEncryptorInterface in peer_connection.cc like below, but when I build I always got some error like this:

error: undefined symbol:webrtc::FakeFrameEncryptor::FakeFrameEncryptor(unsigned char,unsigned char)

Sorry I am really new to C++ and I could not understand where should I put this FakeFrameEncryptor

I already do this in PeerConnection.cc

#include "api/test/fake_frame_decryptor.h"

#include "api/test/fake_frame_encryptor.h"

#include "api/crypto/frame_decryptor_interface.h"

#include "api/crypto/frame_encryptor_interface.h"

Below is how I attach fake encryptor, I will also attach my peer_connection.cc's and fakeFrameEncryptor file below

if (kind == MediaStreamTrackInterface::kAudioKind) {

auto audio_sender = AudioRtpSender::Create(

worker_thread(), rtc::CreateRandomUuid(), stats_.get(), rtp_manager());

audio_sender->SetMediaChannel(rtp_manager()->voice_media_channel());

new_sender = RtpSenderProxyWithInternal<RtpSenderInternal>::Create(

signaling_thread(), audio_sender);

rtp_manager()->GetAudioTransceiver()->internal()->AddSender(new_sender);

} else if (kind == MediaStreamTrackInterface::kVideoKind) {

// Initiate frame encryptor

rtc::scoped_refptr<FrameEncryptorInterface> fake_frame_encryptor(

new FakeFrameEncryptor());

auto video_sender = VideoRtpSender::Create(

worker_thread(), rtc::CreateRandomUuid(), rtp_manager());

video_sender->SetMediaChannel(rtp_manager()->video_media_channel());

// Set frame encryptor to the sender.

video_sender->SetFrameEncryptor(fake_frame_encryptor);

new_sender = RtpSenderProxyWithInternal<RtpSenderInternal>::Create(

signaling_thread(), video_sender);

rtp_manager()->GetVideoTransceiver()->internal()->AddSender(new_sender);

} else {

RTC_LOG(LS_ERROR) << "CreateSender called with invalid kind: " << kind;

return nullptr;

}

new_sender->internal()->set_stream_ids(stream_ids);

return new_sender;

}

Thank you so much, I really appreciate your time and help
