Is any way that is safe to display videos in a browser, Like, one of his security things, the video cannot be downloaded thanks

推荐答案

我认为您的意思是您不想下载或复制您的视频?

I think you mean that you don't want your video to be downloaded or copied?

如果是这样，那么阻止人们下载视频或多或少是不可能的 - 即使从 YouTube 等大型提供商那里也有许多工具可供下载.

If so then it is more or less impossible to stop people downloading the video - there are many tools available to download even from big providers like YouTube.

所以最常用的方法是对视频进行加密，并使用 HTML5 的加密媒体扩展 (EME) 来处理安全播放 - 基本上支持视频的 DRM.

So the approach most take is to encrypt the video and use HTML5's Encrypted Media Extension (EME) to handle secure playback - basically support DRM on the video.

如果您只是想设置一个基本障碍来阻止临时用户复制视频，那么 MPEG DASHclearkey"加密或 HLS AES 加密可能足以满足您的需求 - 大多数大型内容所有者认为这些并不可靠，但可能简单使用就可以了.

If you just want to put a basic barrier to stop casual users copying the video then MPEG DASH 'clearkey' encryption or HLS AES encryption may be sufficient for your needs - these are not considered robust by most large content owners, but may be fine for simple use.

您可以使用 ffmpeg 和 openssl 来创建 AES 加密的 HLS 流 - ffmpeg 文档 (http://ffmpeg.org/ffmpeg-all.html#Options-34) 包含此示例脚本:

You can use ffmpeg and openssl to create an AES encrypted HLS stream - the ffmpeg documentation (http://ffmpeg.org/ffmpeg-all.html#Options-34) includes this example script:

#!/bin/sh
BASE_URL=${1:-'.'}
openssl rand 16 > file.key
echo $BASE_URL/file.key > file.keyinfo
echo file.key >> file.keyinfo
echo $(openssl rand -hex 16) >> file.keyinfo
ffmpeg -f lavfi -re -i testsrc -c:v h264 -hls_flags delete_segments 
  -hls_key_info_file file.keyinfo out.m3u8

您也可以使用 mp4Box (https://gpac.wp.imt.fr/mp4box/encryption/common-encryption/) 创建基本的 DASH 加密:

You can also use mp4Box (https://gpac.wp.imt.fr/mp4box/encryption/common-encryption/) to create basic clear DASH encryptions:

MP4Box -crypt drm_file.xml movie.mp4 -out movie_encrypted.mp4

MP4Box -crypt drm_file.xml movie.mp4 -out movie_encrypted.mp4

drm 信息包含在 drm_file.xml 中，并在上面的链接中进行了说明.

The drm info is included in the drm_file.xml and is explained at the link above.
