Hello davidghukasyan~

Thank you for registering issue.
I succeeded in reproducing the problem based on your comments.
It seems to be a compatibility issue with nimble streamer, but it may take several days to find the exact cause. (Actually, I'm not familiar with the nimble streamer :)
I'll let you know the results as soon as possible.

[davidghukasyan]

thanks a lot, will be waiting for a feedback.

[sfreet]

This issue was resolved in version f1e60e3.
(It turns out that this problem has nothing to do with nimble streamer)
If the problem persists, please let me know again.
Thank you again for your contributions David.

now I get an info during the installation.

[ 2/166| 1%] [static] libovcrypto.a: C++ projects/base/ovcrypto/certificate.cpp => intermediates/DEBUG/objs/base/ovcrypto/certificate.o

^~~~~~~~~~~

Is it the same system you used the last time?
Could you just try to run "make clean" and "make" again?

[davidghukasyan]

Yes its the same system.
Unfortunatly it doesnt help.
I even tried to download instead of git, but the result is same.

Good morning David.
"'X509_up_ref' was not declared in this scope" means that the SSL header is not found or is an older header.
I think your system's ssl library version has changed since the last installation. (Of course, It's not your intentional action - when you install other programs)
First, check out the openssl version as follows

$ openssl version
OpenSSL 1.1.0g 2 Nov 2017

Next, checking the header location

$ pkg-config --cflags openssl
-I /usr/local/include

Next, checking the function

$ cat /usr/local/include/openssl/x509.h | grep X509_up_ref
int X509_up_ref (X509 * x);

It is normal that X509_up_ref should be searched.
If not, try reinstalling ssl library for your OS as described in OvenMediaEngine.
(ex. ubuntu - apt install libssl-dev, fedora - yum install openssl-devel, centos - OpenSSL 1.1.0g Download and make install)

If this does not solve the above problem, please let me know your system information(OS name, version) with the above command execution result.
Thnak you~

hi , thank you , Openssl reinstall helped.
I am getting
I 3565 TranscodeStream | transcode_stream.cpp:437 | Queue(filtered) is full, please decrease encoding options(resolution,bitrate,framerate)
I configured 1280x720 , 1800000 bitrate, which is a minimum requirment for me, is there any way to increase the queue/frame buffer ?

[sfreet]

Do you have any problems with playing the media?
The message is not an error message and can be safely ignored if it is not repeated frequently and continuously.
(Increasing buffer isn't a solution)
If there is a problem with media playback and the message continues to repeat, try lowering the resolution, bitrate.
If it is not possible to do so, one solution is to use a higher specification system than the one you are using now.

[sfreet]

I close this issue. If the issue is not resolved, please let us know again.
Thanks again for your contributions @davidghukasyan
