The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods install

博客提到,若遇到相关问题,可通过删除Bulid Phases中的Check Pods Manifest.lock来解决,这可能是在CocoaPods使用过程中的一个处理办法。

删除Bulid Phases中的 Check Pods Manifest.lock 即可


你遇到的错误: > **"The media could not be loaded, either because the server or network failed or because the format is not supported."** 说明视频标签(`<video>`)已经存在,但浏览器无法加载媒体资源。这通常意味着: - 视频 URL 请求被阻止或返回失败(403/404/CORS) - 媒体格式不支持(如 `.m3u8` 未启用 HLS 支持) - 缺少必要的请求头(如 `Referer`, `Origin`, `Authorization`) - 被 CDN 或后端识别为自动化访问并拒绝服务 - 浏览器未正确启用媒体解码功能(尤其是无头模式下) --- ### ✅ 深度分析与解决方案 #### ✅ 1. **检查真实视频请求是否发出?** 使用 Playwright 监听网络请求,确认是否发起了对 `.mp4`、`.m3u8`、`.ts` 等视频资源的请求,并查看状态码。 ```python def run(playwright): browser = playwright.chromium.launch( headless=False, args=[ "--disable-blink-features=AutomationControlled", "--mute-audio", "--no-sandbox", "--allow-media-stream", # 允许媒体流 "--use-fake-ui-for-media-stream", "--use-fake-device-for-media-stream" ] ) context = browser.new_context( viewport={"width": 1920, "height": 1080}, user_agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36", locale="zh-CN", timezone_id="Asia/Shanghai" ) # 绕过 webdriver 检测 context.add_init_script(""" Object.defineProperty(navigator, 'webdriver', { get: () => false }); window.chrome = { runtime: {}, loadTimes: () => {}, csi: () => {} }; Object.defineProperty(navigator, 'languages', { get: () => ['zh-CN', 'zh', 'en'] }); Object.defineProperty(navigator, 'plugins', { get: () => [1, 2, 3, 4, 5] }); """) page = context.new_page() # === 监听网络请求 === def log_request(req): if "m3u8" in req.url or ".mp4" in req.url or "video" in req.resource_type: print(f"📹 Video request: {req.url} | Type: {req.resource_type}") def log_response(res): if "m3u8" in res.url or ".mp4" in res.url or "ts" in res.url: print(f"📥 Response: {res.url} | Status: {res.status}") if res.status != 200: print(f"❌ Failed to load video resource! Status: {res.status}") page.on("request", log_request) page.on("response", log_response) # 设置额外请求头(模拟正常浏览) page.set_extra_http_headers({ "Referer": "https://www.google.com/", "Origin": "https://your-video-site.com", }) try: page.goto("https://example.com/video-page.html", wait_until="networkidle") page.wait_for_selector("video", timeout=10000) # 尝试播放 page.eval_on_selector("video", """ video => { video.muted = true; video.autoplay = true; video.playsInline = true; video.play().catch(e => console.error('Play error:', e)); } """) # 等待一段时间观察结果 page.wait_for_timeout(15000) # 检查播放状态 is_playing = page.eval_on_selector("video", """ video => ({ paused: video.paused, ended: video.ended, currentTime: video.currentTime, error: video.error ? video.error.code : null }) """) print("Playback state:", is_playing) except Exception as e: print(f"Error: {e}") context.close() browser.close() with sync_playwright() as p: run(p) ``` --- ### ✅ 2. **常见修复方法汇总** | 问题类型 | 解决方案 | |--------|---------| | ❌ 自动播放被禁用 | 添加 `--mute-audio` 启动参数 + JS 设置 `muted=true` | | ❌ 缺少 Referer 导致 403 | 使用 `set_extra_http_headers({"Referer": "..."})` | | ❌ 请求被 CORS 阻止 | 使用 `--disable-web-security`(仅测试)或代理中转 | | ❌ 视频是 HLS (.m3u8) 格式 | Chromium 默认支持有限,需确保启用 Media Source Extensions | | ❌ 被服务器封禁 IP/User-Agent | 使用真实 User-Agent + 国内代理 | | ❌ DRM 加密视频(如 Widevine) | 必须启用支持且设备已授权(Playwright 默认可能不支持) | --- ### ✅ 3. 强制启用媒体支持的启动参数(重要!) ```python args=[ "--autoplay-policy=no-user-gesture-required", # 允许无交互自动播放 "--disable-blink-features=AutomationControlled", "--mute-audio", "--use-fake-device-for-media-stream", "--use-fake-ui-for-media-stream", "--allow-media-stream", "--enable-media-stream", "--no-sandbox", "--start-maximized" ] ``` --- ### ✅ 4. 手动获取视频源地址并验证 有时 `<video>` 的 `src` 是空的,实际通过 JavaScript 动态添加。你可以手动提取: ```python # 获取 video 元素的所有 source sources = page.eval_on_selector("video", """ video => Array.from(video.querySelectorAll("source")).map(s => s.src) """) print("Video sources:", sources) # 或直接读取 .src 属性 src = page.eval_on_selector("video", "video => video.src") print("Direct src:", src) ``` 然后在浏览器中新开标签页访问这个链接,看是否能播放。 --- ### ✅ 5. 替代方案:使用 FFmpeg + requests 下载测试 如果只是想“下载”或“检测”视频是否可访问,可以直接用 Python 发起带 Headers 的请求: ```python import requests headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36", "Referer": "https://example.com/video-page.html", "Origin": "https://example.com" } response = requests.get("https://example.com/path/to/video.m3u8", headers=headers, stream=True) if response.status_code == 200: print("✅ 视频可以访问!") else: print("❌ 被拒绝:", response.status_code, response.text) ``` ---
