ios - "No Source Video Found"错误仅适用于 HLS 流、Kaltura CE 6 和 Wowza 4.1

Question

我在使用 HLS 流和 HTML5 mwembed 视频播放器时遇到问题。我正在使用 mwembed v2.29.1.2、Kaltura CE 6.0 和 Wowza Streaming Engine 4.1.2。通过 Kaltura Flash 视频播放器播放视频效果很好(通过 Wowza 使用 RTMP 进行流式传输)但是当尝试在 iOS 设备上访问视频时，我收到消息“错误:找不到源视频。”

我直接测试了 Wowza 流式传输，直接播放任何视频都没有问题:http://wowza.medquestreviews.com/kaltura/_definst_/mp4:content/entry/data/4/268/0_uxutn4hk_0_v5nyr0u2_1/playlist.m3u8

这是一个有问题的视频:http://medquestreviews.com/step-3-high-yield/hematology/chapter-3-transfusion-reactions

我查看了 Kaltura 日志文件、apache_access、apache_errors、Kaltura_api_v3 等，我能找到的与此相关的唯一错误是 apache 日志中的 "error-10" 和[thumbnailAction->execute] 注意:错误 - api 日志中没有条目的 FileSync。

如何找到 Kaltura 用于查找 HLS 流的 URL？我仔细检查了远程存储设置，一切正常。

访问 m3u8 播放列表/ list 本身也有效:http://kmc.medquestreviews.com/p/101/sp/10100/playManifest/entryId/0_uxutn4hk/format/applehttp/a.m3u8

HTML5 播放器的 JS 调试输出是:

日志中的错误也略有不同，具体取决于我是用嵌入视频加载整个页面还是尝试从 iframe 播放器配置 JS 加载 dataUrl。

已解决。我们通过使用更新版本的 Kaltura CE 并使用其中包含的 native HLS 集成来修复此问题。我们还升级了播放器和 HLS 插件。
