UnifiedPlayer Testing Checklist

Video Functionality Testing

• Basic video playback starts without crashing
• Video frames display correctly in Fyne canvas
• Frame rate matches source video (30fps, 24fps, 60fps)
• Resolution scaling works properly
• No memory leaks during video playback
• Clean video-only playback (no audio stream files)

Audio Functionality Testing

• Audio plays through system speakers
• Audio volume controls work correctly (0-100%)
• Mute/unmute functionality works
• A/V synchronization stays in sync (no drift)
• Audio works with different sample rates
• Audio stops cleanly on Stop()/Pause()

Play/Pause/Seek Controls

• Play() starts both video and audio immediately
• Pause() freezes both video and audio frames
• Seek() jumps to correct timestamp instantly
• Frame stepping works frame-by-frame
• Resume after pause continues from paused position

️ Error Handling & Edge Cases

• Missing video file shows user-friendly error
• Corrupted video file handles gracefully
• Unsupported format shows clear error message
• Audio-only files handled without crashes
• Resource cleanup on player.Close()

Performance & Resource Usage

• CPU usage is reasonable (<50% on modern hardware)
• Memory usage stays stable (no growing leaks)
• Smooth playback without stuttering
• Fast seeking without rebuffering delays
• Frame extraction is performant at target resolution

Cross-Platform Testing

• Works on different video codecs (H.264, H.265, VP9)
• Handles different container formats (MP4, MKV, AVI)
• Works with various resolutions (720p, 1080p, 4K)
• Audio works with stereo/mono sources
• No platform-specific crashes (Linux/Windows/Mac)

Technical Validation

• FFmpeg process starts with correct args
• Pipe communication works (video + audio)
• RGB24 → RGBA conversion is correct
• oto audio context initializes successfully
• Frame display loop runs at correct timing
• A/V sync timing calculations are accurate

Key Success Metrics

• Video plays without crashes
• Audio is audible and in sync
• Seeking is frame-accurate and responsive
• Frame stepping works perfectly
• Resource usage is optimal
• No memory leaks or resource issues
