mediasoup broadcaster demo (libmediasoupclient)

mediasoup broadcaster demo (libmediasoupclient v3)

libmediasoupclient based application that produces artificial sound and video to the specified room in mediasoup-demo application. The video consists of some colored rectangles moving towards the lower-right corner of the image. Credit for the artificial media creation goes to the WEBRTC team (LICENSE).

Environment variables:

• SERVER_URL: The URL of the mediasoup-demo HTTP API server (required).
• ROOM_ID: Room id (required).
• USE_SIMULCAST: If "false" no simulcast will be used (defaults to "true").
• ENABLE_AUDIO: If "false" no audio Producer is created (defaults to "true").
• WEBRTC_DEBUG: Enable libwebrtc logging. Can be "info", "warn" or "error" (optional).

Dependencies

• libmediasoupclient (already included in the repository)
• cpr (already included in the repository)
• OpenSSL (must be installed in the system including its headers)

Installation

git clone https://github.com/versatica/mediasoup-broadcaster-demo.git

Linkage Considerations (1)

[ 65%] Linking C shared library ../../../../lib/libcurl.dylib ld: cannot link directly with dylib/framework, your binary is not an allowed client of /usr/lib/libcrypto.dylib for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [lib/libcurl.dylib] Error 1 make[1]: *** [cpr/opt/curl/lib/CMakeFiles/libcurl.dir/all] Error 2
make: *** [all] Error 2

The following error may happen if the linker is not able to find the openssl crypto library. In order to avoid this error, specify the crypto library path along with the openssl root directory using the OPENSSL_CRYPTO_LIBRARY flag. Ie:

-DOPENSSL_ROOT_DIR=/usr/local/Cellar/[email protected]/1.1.1h \
-DOPENSSL_CRYPTO_LIBRARY=/usr/local/Cellar/[email protected]/1.1.1h/lib/libcrypto.1.1.dylib

License

Some files contain specific license agreements, written in the beginning of the respective files.

NOTE 1: PATH_TO_OPENSSL_HEADERS is /usr/local/opt/openssl/include if you install OpenSSL using Homebrew in OSX.

mediasoup-broadcaster-demo's Issues

Excuse me! Does the latest Mediasoup support the latest Webrtc （M79 Release）

Excuse me! Does the latest mediasoup supported the latest webrtc（release M79）

Excuse me! Does the latest mediasoup supported the latest webrtc（release M79）

webrtc library needs to be build with tests

I guess because of the usage of "webrtc::FakePeriodicVideoTrackSource", the webrtc library needs to be build including tests. This is described here, but not specifically noted in this project, which cannot be build without it.

update to last libmediasoupclient v3 (libwebrtc m81)

I'm facing an issue when trying to upgrade to libmediasoupclient v3 which now uses libwebrtc m81 version.

After upgrading the files in our fakegenerators folder, which have changed in libwebrtc, I'm getting the following Undefined symbols linking error:

[ 72%] Linking CXX executable broadcaster

I can't spot the reason since libwebrtc is being compiled with the following args (see: rtc_include_tests:

[email protected]:~/src/webrtc-checkout/src ((HEAD detached at branch-heads/4044))$ cat out/4044/args.gn
is_debug = true
is_component_build = false
is_clang = true
rtc_include_tests = true
rtc_use_h264 = true
rtc_enable_protobuf = false
use_rtti = true
mac_deployment_target = "10.11"
use_custom_libcxx = false

I'm wondering if you could give it a shoot @copiltembel.

Thanks a lot.

The line in the CMakeLists.txt is as follows:

Honestly I have no idea about what ${SOURCES} it.

I've cmake 3.9.4 which satisfies the required version.

Issue compiling: missing rtc_base/critical_section.h

I'm trying to compile this demo under macOS using webrtc branch 4606 (m94). It appears there is a missing file. Are we still using 4606 as described in the Mediasoup docs?

As an FYI, I followed the documentation for libmediasoupclient for installing webrtc and exactly did what is mentioned here:
https://mediasoup.org/documentation/v3/libmediasoupclient/installation/. Is there another branch head I should be trying with instead of m84?

Possibly related issue I filed for libmediasoupclient: versatica/libmediasoupclient#89

which webrtc project use?

-DLIBWEBRTC_INCLUDE_PATH:PATH=${PATH_TO_LIBWEBRTC_SOURCES}
-DLIBWEBRTC_BINARY_PATH:PATH=${PATH_TO_LIBWEBRTC_BINARY} \

OnConnect(mediasoupclient::Transport* transport, const nlohmann::json& dtlsParameters) why no callback ?

Now I run the broadcaster demo,but libsdptransform use jason parse curl receive text crash.

This code committed 5 months ago. Whether server website changed. The mediasoup broadcaster do not change.

compile error on Mac - can't use built in openssl lib

Im trying to compile the lib on MacOS Catalina.

In the last step: make -C build
The process fails with the message:

[ 65%] Linking C shared library ../../../../lib/libcurl.dylib ld: cannot link directly with dylib/framework, your binary is not an allowed client of /usr/lib/libcrypto.dylib for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: *** [lib/libcurl.dylib] Error 1 make[1]: *** [cpr/opt/curl/lib/CMakeFiles/libcurl.dir/all] Error 2 make: *** [all] Error 2
Note: I have set the PATH_TO_OPENSSL_HEADERS in the command to /usr/local/opt/openssl/include as instructed in the README

Any solutions to this?

Does this demo support Win10 now?

Overlay stream trouble

Hi, I experimenting with this demo, sending generally works (a bit confusing how to control the bitrate, but I think I'll find the answer in the mediasoup documentation).

The problem occurred while trying to overlay a stream from mediasoup to another stream (udp, rtmp, etc.).

I understand that this is not a problem with this repository, but perhaps a fresh look and experience with mediaasoup will help localize the problem.

According to ffmpeg logs, it starts working, processes for a while and stops (line 957 of the log file)

I suspect there is something wrong with the stream from mediaasoup

any idea? thanks

Project doesn't work when pointing to https://v3demo.mediasoup.org

Just compiled the project on aws server, and trying to run it against https://v3demo.mediasoup.org, by using the command line:
SERVER_URL=https://v3demo.mediasoup.org ROOM_ID=8ktvbiip build/broadcaster

It's not working as the url:
https://v3demo.mediasoup.org/rooms/8ktvbiip
returns 404.
Should it work with V3? can it only work in local installations?
