添加动画效果增强用户体验：

动画效果示例

/* 录制按钮动画 */
.vjs-record-button {
    transition: all 0.3s cubic-bezier(0.4, 0, 0.2, 1) !important;
    transform: scale(1) !important;
}

.vjs-record-button:hover {
    transform: scale(1.05) !important;
}

.vjs-record-button:active {
    transform: scale(0.95) !important;
}

/* 录制指示器动画 */
.vjs-record-indicator {
    animation: pulse 2s infinite !important;
}

@keyframes pulse {
    0% {
        transform: scale(1);
        box-shadow: 0 0 0 0 rgba(220, 53, 69, 0.7);
    }
    70% {
        transform: scale(1.1);
        box-shadow: 0 0 0 10px rgba(220, 53, 69, 0);
    }
    100% {
        transform: scale(1);
        box-shadow: 0 0 0 0 rgba(220, 53, 69, 0);
    }
}

/* 进度条动画 */

    transition: width 0.5s ease-in-out !important;
}

/* 按钮点击动画 */
@keyframes buttonClick {
    0% { transform: scale(1); }
    50% { transform: scale(0.9); }
    100% { transform: scale(1); }
}

.vjs-record-button.clicked {
    animation: buttonClick 0.3s ease !important;
}

/* 录制完成动画 */
@keyframes recordComplete {
    0% { background-color: #00758F; }
    50% { background-color: #28a745; }
    100% { background-color: #00758F; }
}

.vjs-record-button.complete {
    animation: recordComplete 1s ease !important;
}

/* 加载动画 */

    border: 4px solid #f3f3f3 !important;
    border-top: 4px solid #00758F !important;
    border-radius: 50% !important;
    width: 30px !important;
    height: 30px !important;
    animation: spin 1s linear infinite !important;
    margin: 0 auto !important;
}

@keyframes spin {
    0% { transform: rotate(0deg); }
    100% { transform: rotate(360deg); }
}

/* 淡入淡出动画 */
.fade-in {
    animation: fadeIn 0.5s ease-in !important;
}

.fade-out {
    animation: fadeOut 0.5s ease-out !important;
}

@keyframes fadeIn {
    from { opacity: 0; transform: translateY(20px); }
    to { opacity: 1; transform: translateY(0); }
}

@keyframes fadeOut {
    from { opacity: 1; transform: translateY(0); }
    to { opacity: 0; transform: translateY(-20px); }
}

12.6 自定义控件

创建自定义控件和UI元素：

自定义控件示例

/* 自定义质量选择器 */
.vjs-quality-selector {
    display: flex !important;
    align-items: center !important;
    margin-left: 15px !important;
}

.vjs-quality-selector label {
    color: #ffffff !important;
    font-size: 14px !important;
    margin-right: 8px !important;
}

.vjs-quality-selector select {
    background-color: rgba(255, 255, 255, 0.2) !important;
    color: white !important;
    border: 1px solid rgba(255, 255, 255, 0.3) !important;
    border-radius: 4px !important;
    padding: 5px 10px !important;
    font-size: 14px !important;
}

.vjs-quality-selector select:focus {
    outline: none !important;
    border-color: #00758F !important;
}

/* 自定义设备选择器 */
.vjs-device-selector {
    display: flex !important;
    flex-direction: column !important;
    margin: 10px !important;
    padding: 15px !important;
    background-color: rgba(0, 0, 0, 0.7) !important;
    border-radius: 8px !important;
}

.vjs-device-selector h4 {
    color: white !important;
    margin: 0 0 10px 0 !important;
    font-size: 16px !important;
}

.vjs-device-selector select {
    width: 100% !important;
    padding: 8px !important;
    margin-bottom: 10px !important;
    border-radius: 4px !important;
    border: 1px solid #ccc !important;
    background-color: white !important;
}

/* 自定义预览窗口 */
.vjs-preview-window {
    position: absolute !important;
    top: 10px !important;
    right: 10px !important;
    width: 150px !important;
    height: 100px !important;
    border: 2px solid #00758F !important;
    border-radius: 4px !important;
    background-color: #000 !important;
    z-index: 1000 !important;
    box-shadow: 0 2px 8px rgba(0, 0, 0, 0.3) !important;
}

.vjs-preview-window video {
    width: 100% !important;
    height: 100% !important;
    object-fit: cover !important;
}

/* 自定义录制统计 */
.vjs-recording-stats {
    position: absolute !important;
    top: 10px !important;
    left: 10px !important;
    background-color: rgba(0, 0, 0, 0.7) !important;
    color: white !important;
    padding: 10px !important;
    border-radius: 4px !important;
    font-size: 12px !important;
    z-index: 1000 !important;
}

.vjs-recording-stats div {
    margin-bottom: 5px !important;
}

.vjs-recording-stats .stat-label {
    display: inline-block !important;
    width: 80px !important;
    color: #ccc !important;
}

.vjs-recording-stats .stat-value {
    font-weight: bold !important;
    color: #00758F !important;
}

提示：在自定义样式时，使用!important可以确保样式优先级，但应谨慎使用，避免过度依赖。
