-------------------------------------------------------------------------------- /docs/GOP_CONFIGURATION.md: -------------------------------------------------------------------------------- 1 | # GOP (Group of Pictures) 配置文档 2 | 3 | ## 概述 4 | 5 | GOP（Group of Pictures）是视频编码中的一个重要概念，它定义了一组连续的视频帧，通常以关键帧（I帧）开始，后跟预测帧（P帧）和双向预测帧（B帧）。本文档描述了如何在livewin-live中配置和使用GOP重编码功能。 6 | 7 | ## 配置选项 8 | 9 | 在 `conf.yaml` 文件中，GOP配置位于 `gop` 部分： 10 | 11 | ```yaml 12 | gop: 13 | enable_reencoding: false # 是否启用GOP重编码功能 14 | target_size: 30 # 目标GOP大小（帧数） 15 | keyframe_interval: 2000 # 关键帧间隔（毫秒） 16 | max_b_frames: 2 # 最大B帧数量 17 | force_keyframe: false # 是否强制插入关键帧 18 | ``` 19 | 20 | ### 配置参数详解 21 | 22 | #### `enable_reencoding` 23 | - **类型**: boolean 24 | - **默认值**: false 25 | - **描述**: 是否启用GOP重编码功能。当设置为true时，服务器将对输入的视频流进行GOP级别的重新编码和优化。 26 | 27 | #### `target_size` 28 | - **类型**: u32 29 | - **默认值**: 30 30 | - **描述**: 目标GOP大小，以帧数为单位。这定义了每个GOP中应该包含多少帧。较大的GOP可以提供更好的压缩效率，但可能增加延迟。 31 | 32 | #### `keyframe_interval` 33 | - **类型**: u32 34 | - **默认值**: 2000 35 | - **描述**: 关键帧间隔，以毫秒为单位。这定义了两个关键帧之间的最大时间间隔。较短的间隔提供更好的随机访问能力，但可能降低压缩效率。 36 | 37 | #### `max_b_frames` 38 | - **类型**: u32 39 | - **默认值**: 2 40 | - **描述**: 最大B帧数量。B帧（双向预测帧）可以提供更好的压缩效率，但会增加编码复杂度和延迟。 41 | 42 | #### `force_keyframe` 43 | - **类型**: boolean 44 | - **默认值**: false 45 | - **描述**: 是否强制插入关键帧。当设置为true时，系统会在GOP达到目标大小时强制插入关键帧，即使时间间隔还没有达到。 46 | 47 | ## 使用场景 48 | 49 | ### 1. 低延迟直播 50 | ```yaml 51 | gop: 52 | enable_reencoding: true 53 | target_size: 15 54 | keyframe_interval: 1000 55 | max_b_frames: 0 56 | force_keyframe: true 57 | ``` 58 | 59 | ### 2. 高质量录制 60 | ```yaml 61 | gop: 62 | enable_reencoding: true 63 | target_size: 60 64 | keyframe_interval: 4000 65 | max_b_frames: 3 66 | force_keyframe: false 67 | ``` 68 | 69 | ### 3. 移动端优化 70 | ```yaml 71 | gop: 72 | enable_reencoding: true 73 | target_size: 25 74 | keyframe_interval: 2000 75 | max_b_frames: 1 76 | force_keyframe: true 77 | ``` 78 | 79 | ## 性能考虑 80 | 81 | ### CPU使用率 82 | 启用GOP重编码会增加CPU使用率，特别是在处理高分辨率视频流时。建议在生产环境中进行充分的性能测试。 83 | 84 | ### 内存使用 85 | GOP处理器需要缓存一定数量的视频帧，这会增加内存使用。较大的GOP大小会需要更多内存。 86 | 87 | ### 延迟影响 88 | GOP重编码可能会引入额外的延迟，特别是当启用B帧时。对于实时应用，建议将`max_b_frames`设置为0或较小的值。 89 | 90 | ## 监控和调试 91 | 92 | ### 日志输出 93 | 当启用GOP重编码时，系统会输出相关的调试信息： 94 | 95 | ``` 96 | [INFO] Starting new GOP with keyframe at timestamp: 1234567890 97 | [DEBUG] Finalized GOP with 30 frames using advanced reencoding 98 | [ERROR] GOP processing error: No keyframe found in GOP 99 | ``` 100 | 101 | ### 错误处理 102 | GOP处理过程中可能出现的错误： 103 | 104 | - `InvalidConfig`: 配置参数无效 105 | - `VideoProcessingError`: 视频数据处理错误 106 | - `BufferOverflow`: GOP缓冲区溢出 107 | - `NoKeyframe`: GOP中没有找到关键帧 108 | 109 | ## 环境变量配置 110 | 111 | 也可以通过环境变量来配置GOP参数： 112 | 113 | ```bash 114 | export XLIVE_GOP_ENABLE_REENCODING=true 115 | export XLIVE_GOP_TARGET_SIZE=30 116 | export XLIVE_GOP_KEYFRAME_INTERVAL=2000 117 | export XLIVE_GOP_MAX_B_FRAMES=2 118 | export XLIVE_GOP_FORCE_KEYFRAME=false 119 | ``` 120 | 121 | ## 最佳实践 122 | 123 | 1. **测试环境验证**: 在生产环境部署前，在测试环境中充分验证GOP配置的效果。 124 | 125 | 2. **监控性能**: 密切监控CPU和内存使用情况，确保系统资源充足。 126 | 127 | 3. **渐进式部署**: 建议先在部分流上启用GOP重编码，观察效果后再全面部署。 128 | 129 | 4. **备份配置**: 保留原始配置文件的备份，以便在需要时快速回滚。 130 | 131 | 5. **日志监控**: 设置适当的日志级别，监控GOP处理的状态和错误。 132 | 133 | ## 故障排除 134 | 135 | ### 常见问题 136 | 137 | **Q: GOP重编码功能无法启用** 138 | A: 检查配置文件中的`enable_reencoding`是否设置为true，并确保没有语法错误。 139 | 140 | **Q: 视频播放出现卡顿** 141 | A: 可能是GOP大小设置过大或B帧数量过多，尝试减小这些值。 142 | 143 | **Q: CPU使用率过高** 144 | A: GOP重编码是CPU密集型操作，考虑减小GOP大小或禁用B帧。 145 | 146 | **Q: 内存使用持续增长** 147 | A: 可能存在内存泄漏，检查日志中的错误信息，并考虑重启服务。 148 | 149 | ## 技术实现 150 | 151 | GOP处理器的核心功能包括： 152 | 153 | 1. **帧类型检测**: 通过解析NAL单元确定帧类型（I/P/B帧） 154 | 2. **GOP边界识别**: 检测关键帧来确定GOP的开始和结束 155 | 3. **帧重排序**: 根据显示时间戳重新排序帧 156 | 4. **时间戳重计算**: 确保输出帧的时间戳连续性 157 | 5. **B帧优化**: 优化B帧的位置以提高压缩效率 158 | 159 | ## 版本兼容性 160 | 161 | - 最低支持版本: v1.0.0 162 | - 推荐版本: v1.2.0+ 163 | - 实验性功能: B帧优化（v1.3.0+） 164 | -------------------------------------------------------------------------------- /src/codec/hevc.rs:
