Pros of SRS

• More active development with frequent updates and releases
• Extensive documentation and community support
• Better support for modern streaming protocols like WebRTC

Cons of SRS

• Higher resource consumption due to its comprehensive feature set
• Steeper learning curve for beginners due to its complexity

Code Comparison

SRS (C++):

SrsRtmpConn::SrsRtmpConn(SrsServer* svr, srs_netfd_t c)
{
    server = svr;
    stfd = c;
    ip = srs_get_peer_ip(c);
    rbytes = sbytes = 0;
    req = new SrsRequest();
}

media-server (C):

int rtmp_server_create(struct rtmp_server_t** pp, const char* ip, int port)
{
    struct rtmp_server_t* ctx;
    ctx = (struct rtmp_server_t*)calloc(1, sizeof(*ctx));
    if (NULL == ctx)
        return -1;
    ctx->aio = aio_socket_create(ip, port, RTMP_SERVER_LISTEN_BACKLOG);
    if (NULL == ctx->aio)
    {
        free(ctx);
        return -1;
    }
    *pp = ctx;
    return 0;
}

Both repositories offer robust media server solutions, but SRS provides a more modern and feature-rich approach with better documentation and community support. However, this comes at the cost of higher resource usage and a steeper learning curve. media-server, on the other hand, offers a more lightweight and straightforward implementation, which may be preferable for simpler use cases or resource-constrained environments.

Pros of FFmpeg

• Extensive codec support and multimedia processing capabilities
• Large, active community with frequent updates and contributions
• Comprehensive documentation and wide range of use cases

Cons of FFmpeg

• Steep learning curve due to complex command-line interface
• Large codebase can be challenging to navigate for newcomers
• Resource-intensive for some operations, especially on low-end devices

Code Comparison

FFmpeg (command-line usage):

ffmpeg -i input.mp4 -c:v libx264 -preset slow -crf 22 -c:a copy output.mp4

media-server (C API usage):

struct avpacket_t pkt;
avpacket_init(&pkt);
avcodec_encode_audio(codec, &pkt, pcm, samples);

Key Differences

• FFmpeg is a comprehensive multimedia framework, while media-server focuses on streaming protocols and real-time communication
• media-server provides a more lightweight solution for specific use cases, whereas FFmpeg offers broader functionality
• FFmpeg has a command-line interface and library, while media-server is primarily used as a C library
• media-server may be easier to integrate for specific streaming applications, but FFmpeg offers more flexibility for general multimedia tasks

Pros of nginx-rtmp-module

• Built as an NGINX module, leveraging NGINX's robust and scalable architecture
• Extensive documentation and community support
• Simpler setup process for those already familiar with NGINX

Cons of nginx-rtmp-module

• Limited to RTMP protocol, while media-server supports multiple protocols
• Less flexibility in terms of customization compared to media-server
• Dependent on NGINX updates and compatibility

Code Comparison

nginx-rtmp-module configuration:

rtmp {
    server {
        listen 1935;
        application live {
            live on;
        }
    }
}

media-server implementation:

struct rtmp_server_t* rtmp = rtmp_server_create(NULL, 1935);
rtmp_server_set_handler(rtmp, RTMP_HANDLER);
rtmp_server_run(rtmp);

The nginx-rtmp-module uses a declarative configuration approach within NGINX, while media-server employs a programmatic C API for server creation and management. nginx-rtmp-module integrates seamlessly with existing NGINX setups, whereas media-server offers more granular control over the RTMP server implementation.

Both projects have their strengths, with nginx-rtmp-module excelling in ease of use and integration with NGINX, while media-server provides greater flexibility and support for multiple streaming protocols.

Pros of mediamtx

• Written in Go, offering better performance and concurrency handling
• Supports more modern protocols like WebRTC and SRT
• More active development with frequent updates and releases

Cons of mediamtx

• Less comprehensive documentation compared to media-server
• Smaller community and fewer contributors
• Limited support for older streaming protocols

Code Comparison

media-server (C++):

int rtmp_server_listen(struct rtmp_server_t* rtmp, const char* ip, int port)
{
    struct aio_rtmp_server_t* server;
    server = (struct aio_rtmp_server_t*)calloc(1, sizeof(*server));
    if (NULL == server)
        return -ENOMEM;
    
    server->rtmp = rtmp;
    return aio_tcp_transport_listen(ip, port, SOMAXCONN, rtmp_server_onaccept, server);
}

mediamtx (Go):

func (s *Server) Start() error {
    for _, protocol := range s.protocols {
        if err := protocol.Start(); err != nil {
            return err
        }
    }
    s.metrics.start()
    return nil
}

The code snippets show different approaches to server initialization and startup. media-server uses C++ with manual memory management, while mediamtx leverages Go's simplicity and built-in concurrency features.

Pros of EasyDarwin

• More active development with recent updates and commits
• Broader support for streaming protocols, including RTSP, RTMP, and HLS
• Larger community and more extensive documentation

Cons of EasyDarwin

• Higher complexity and steeper learning curve
• Potentially heavier resource usage due to more features

Code Comparison

EasyDarwin (C++):

int EasyDarwin::StartStreaming(const char* streamName, const char* rtspUrl)
{
    // Implementation for starting a stream
}

media-server (C):

int media_server_start_stream(const char* stream_name, const char* rtsp_url)
{
    // Implementation for starting a stream
}

Key Differences

• EasyDarwin is primarily written in C++, while media-server is written in C
• EasyDarwin offers a more comprehensive streaming solution with additional features
• media-server has a simpler codebase and may be easier to integrate into existing projects

Use Cases

• Choose EasyDarwin for complex streaming setups with multiple protocols and advanced features
• Opt for media-server when a lightweight, simple streaming solution is needed or when working with C-based projects

Community and Support

• EasyDarwin has a larger user base and more active community support
• media-server has fewer contributors but may offer more direct support from the main developer

Pros of webrtc

• Written in Go, offering better performance and concurrency handling
• More active development with frequent updates and contributions
• Comprehensive WebRTC implementation, including DTLS, SRTP, and ICE

Cons of webrtc

• Focused solely on WebRTC, less versatile for other media server use cases
• Steeper learning curve for developers not familiar with Go

Code Comparison

media-server (C++):

int rtsp_server_listen(void* server, const char* ip, int port)
{
    struct rtsp_server_t* ctx = (struct rtsp_server_t*)server;
    return aio_socket_listen(ctx->aio, ip, port, rtsp_server_onaccept, ctx);
}

webrtc (Go):

func (s *WebRTCServer) Listen(addr string) error {
    l, err := net.Listen("tcp", addr)
    if err != nil {
        return err
    }
    s.listener = l
    return nil
}

Both repositories provide media server functionality, but with different focuses. media-server is a more comprehensive media server solution written in C++, supporting various protocols like RTSP, RTMP, and HLS. webrtc, on the other hand, is a specialized WebRTC implementation in Go, offering a modern and performant solution for real-time communication. The choice between the two depends on specific project requirements and the preferred programming language.
