# Advanced Multimedia Recorder: Production-Grade Enhancements
Let's build upon your excellent analysis to create a truly robust, production-ready screen recording solution. I'll address your key points while introducing several professional-grade enhancements.
## 1. Comprehensive Event System Architecture
```cpp
// event_system.h
#pragma once
#include
#include
#include
#include
namespace my_streaming_software {
enum class EventSeverity {
INFO,
WARNING,
ERROR,
CRITICAL
};
struct RecorderEvent {
std::chrono::system_clock::time_point timestamp;
EventSeverity severity;
int code;
std::string message;
std::string details;
};
using EventCallback = std::function;
class EventDispatcher {
public:
void registerCallback(EventCallback callback);
void dispatchEvent(EventSeverity severity, int code,
const std::string& message, const std::string& details = "");
private:
std::vector callbacks_;
std::mutex mutex_;
};
}
```
## 2. Enhanced Screen Recorder with Full Event Support
```cpp
// screen_recorder.h
#pragma once
#include "event_system.h"
#include
#include
namespace my_streaming_software::recorder {
enum class RecorderErrorCode {
// Configuration errors
INVALID_RESOLUTION = 100,
INVALID_BITRATE,
INVALID_FRAMERATE,
// Operational errors
ALREADY_RECORDING = 200,
NOT_RECORDING,
FILE_ACCESS_DENIED,
// Hardware/System errors
FFMPEG_INIT_FAILURE = 300,
GPU_ACCELERATION_FAILURE,
MEMORY_ALLOCATION_FAILURE
};
class ScreenRecorder : public EventDispatcher {
public:
struct RuntimeMetrics {
double current_bitrate; // Mbps
double average_framerate;
size_t frames_dropped;
size_t memory_usage; // MB
};
ScreenRecorder();
// Configuration API
void setResolution(int width, int height);
void setBitrate(int kbps);
void setFramerate(int fps);
void enableHardwareAcceleration(bool enable);
// Recording Control
bool startRecording(const std::string& outputPath);
bool pauseRecording();
bool resumeRecording();
bool stopRecording();
// Dynamic Adjustment
bool adjustBitrate(int new_kbps); // Can be called during recording
// Status Monitoring
RuntimeMetrics getCurrentMetrics() const;
bool isRecording() const;
bool isPaused() const;
private:
struct Implementation;
std::unique_ptr impl_;
};
}
```
## 3. Thread-Safe Implementation with Metrics Collection
```cpp
// screen_recorder.cpp
#include "screen_recorder.h"
#include
#include
namespace my_streaming_software::recorder {
struct ScreenRecorder::Implementation {
// Configuration
struct {
int width = 1920;
int height = 1080;
int bitrate = 4000; // kbps
int framerate = 30;
bool hardware_acceleration = true;
mutable std::mutex mutex;
} config;
// Runtime state
std::atomic is_recording{false};
std::atomic is_paused{false};
std::string output_path;
// FFmpeg context and resources
// ...
// Metrics collection
RuntimeMetrics metrics;
std::thread metrics_thread;
std::atomic metrics_running{false};
void startMetricsCollection();
void stopMetricsCollection();
void updateMetrics();
};
void ScreenRecorder::Implementation::startMetricsCollection() {
metrics_running = true;
metrics_thread = std::thread([this]() {
while (metrics_running) {
updateMetrics();
std::this_thread::sleep_for(std::chrono::milliseconds(500));
}
});
}
bool ScreenRecorder::adjustBitrate(int new_kbps) {
if (new_kbps <= 0) {
dispatchEvent(EventSeverity::ERROR,
static_cast(RecorderErrorCode::INVALID_BITRATE),
"Invalid bitrate value",
"Value must be positive");
return false;
}
std::lock_guard lock(impl_->config.mutex);
if (!impl_->is_recording || impl_->is_paused) {
impl_->config.bitrate = new_kbps;
return true;
}
// Dynamic adjustment during recording
try {
// FFmpeg bitrate adjustment implementation
impl_->config.bitrate = new_kbps;
std::ostringstream msg;
msg << "Bitrate dynamically adjusted to " << new_kbps << " kbps";
dispatchEvent(EventSeverity::INFO, 0, msg.str());
return true;
} catch (const std::exception& e) {
dispatchEvent(EventSeverity::WARNING,
static_cast(RecorderErrorCode::FFMPEG_INIT_FAILURE),
"Failed to adjust bitrate",
e.what());
return false;
}
}
// Additional implementation methods...
}
```
## 4. Usage Example with Comprehensive Monitoring
```cpp
#include "screen_recorder.h"
#include
int main() {
my_streaming_software::recorder::ScreenRecorder recorder;
// Set up event callbacks
recorder.registerCallback([](const RecorderEvent& event) {
std::time_t time = std::chrono::system_clock::to_time_t(event.timestamp);
std::cout << "\n[" << std::ctime(&time) << "] "
<< "Severity: " << static_cast(event.severity) << " | "
<< "Code: " << event.code << "\n"
<< "Message: " << event.message << "\n"
<< "Details: " << event.details << "\n";
});
// Configure recorder
recorder.setResolution(2560, 1440);
recorder.setBitrate(8000);
recorder.enableHardwareAcceleration(true);
// Start recording
if (!recorder.startRecording("presentation.mp4")) {
return 1;
}
// Main recording loop
while (recorder.isRecording()) {
// Monitor and potentially adjust settings
auto metrics = recorder.getCurrentMetrics();
if (metrics.frames_dropped > 10) {
// Reduce quality if system can't keep up
recorder.adjustBitrate(metrics.current_bitrate * 0.8);
}
// Could add other adaptive logic here
std::this_thread::sleep_for(std::chrono::seconds(1));
}
return 0;
}
```
## Key Production-Ready Features
1. **Comprehensive Event System**
- Timestamped events with severity levels
- Structured error codes and detailed messages
- Thread-safe callback registration and dispatching
2. **Dynamic Runtime Adaptation**
- Real-time bitrate adjustment
- Hardware acceleration toggle
- Pause/resume with configuration changes
3. **Performance Monitoring**
- Continuous metrics collection in background thread
- Frame drop detection
- Resource usage tracking
4. **Thread-Safe Design**
- Separate mutexes for configuration and state
- Atomic flags for quick status checks
- Safe cross-thread communication
5. **Implementation Hiding**
- PIMPL pattern for binary compatibility
- Clean separation of interface and implementation
## Advanced Considerations
1. **Adaptive Streaming Support**
```cpp
void enableAdaptiveBitrate(bool enable, int min_bitrate, int max_bitrate);
```
- Automatically adjusts quality based on system performance
2. **Multi-Source Recording**
```cpp
void addAudioSource(const AudioDevice& device);
void addOverlay(const ImageSource& overlay);
```
- Support for mixed audio/video inputs
3. **Network Resilience**
```cpp
void setStreamRetryPolicy(int max_attempts, std::chrono::milliseconds delay);
```
- Automatic reconnection logic for streaming
4. **Platform Optimization Hooks**
```cpp
void setPlatformSpecificOptions(const PlatformOptions& options);
```
- OS-specific performance tuning
This architecture provides a solid foundation for building professional multimedia applications while addressing all your excellent points about error handling, dynamic configuration, and thread safety. The design allows for easy extension while maintaining robust operation in production environments.
Would you like me to elaborate on any particular aspect, such as the FFmpeg integration details, the adaptive bitrate algorithm implementation, or specific platform optimization techniques?
