adobe - 如何将 Adob​​e Connect 录制文件导出为视频？

Question

我有录制会议的链接，如何从中导出视频？

Answer 1

1. 登录您的 Adob​​e Connect 帐户
2. 单击会议 >我的会议
3. 点击录音链接
4. 点击“<strong>录音”链接（屏幕右侧）
5. 单击“<em>名称”列中的链接
6. 复制“<em>查看 URL”——例如， http: //mycompany.adobeconnect.com/p12345678/
7. 将其粘贴到新的浏览器选项卡中，然后将以下内容添加到 URL 的末尾：output/filename.zip?download=zip
8. 您的 URL 应类似于此示例http://mycompany.adobeconnect.com/p12345678/output/filename.zip?download=zip

Answer 2

我编写了这个 Python 脚本来将 Adob​​e Connect 记录导出为视频：

'''
Requirements:
- python 2.7 or 3
- wget, unzip, and ffmpeg accessible from command line.

Examples:
python connect2vid_v2.py https://my.adobeconnect.com/pqc06mcawjgn/  --output_filename=" Understanding how the Network impacts your service"

Please email Franck Dernoncourt <franck.dernoncourt@gmail.com> if you improve this code.

关于脚本如何工作的说明：

假设 Adob​​e Connect ID 是 p6vwxp2d0c2f，即 URL 是https://my.adobeconnect.com/p6vwxp2d0c2f。您可以/output/p6vwxp2d0c2f.zip?download=zip在 URL 的末尾添加以下载一些包含大量音频和视频文件以及一些 .xml 文件的 zip 存档。例如，https ://my.adobeconnect.com/p6vwxp2d0c2e/output/p6vwxp2d0c2e.zip?download=zip可能包含：

• cameraVoip_ _ .xml 包含音频 + 网络摄像头（如果有）。
• screenshare_ _ .xml 包含音频 + 网络摄像头（如果有）。

要合并它们，您可以使用ffmpeg（我ffmpeg从 Oliver Wang / Yannick Hold-Geoffroy / Aaron Hertzmann 那里得到命令）：

ffmpeg -i cameraVoip_1_11.flv -i screenshare_2_10.flv -c copy -map 0:a:0 -map 1:v:0 -shortest output.flv

在哪里：

• -map 0:a:0: 映射仅用于音频的第一个输入文件。
• -map 1:v:0: 映射仅用于视频的第二个输入文件。
• -shortest：如果 cameraVoip_1_11.flv 和 screenshare_2_10.flv 的长度不同，请剪切音频或视频。

如果您想保留网络摄像头视频并将其放置在视频屏幕共享的某个角落：

ffmpeg -i cameraVoip_1_11.flv -i screenshare_2_10.flv  \
                         -filter_complex \
                         "color=s=1072x480:c=black [base]; [0:v] setpts=PTS-STARTPTS, scale=640x480 [upperleft]; [1:v] setpts=PTS-STARTPTS, scale=432x240 [upperright]; [base][upperleft] overlay=shortest=1 [tmp1]; [tmp1][upperright] overlay=shortest=1:x=640" \
                         -c:v libx264 -c:a mp2 output.mkv

关于将 cameraVoip_ _ .xml 映射到正确的 screenshare_ _ .xml，以防有多个：

可以查看 cameraVoip_ _ .xml / screenshare_ _ .xml 以获取音频/屏幕共享视频开始的时间戳。这允许将 screenshare_ _ .xml 映射到正确的 cameraVoip_ _ .xml。

例如，在https://my.adobeconnect.com/p6vwxp2d0c2f/output/p6vwxp2d0c2f.zip?download=zip中，来自 cameraVoip_1_11.xml 第 21 行：

<String><![CDATA[Thu Feb 07 21:11:23 2019]]></String>

否则，另一种方法可能是对 cameraVoip_ _ .xml / screenshare_ _ .xml 进行排序，然后将第一个 cameraVoip_ _ .xml 与第一个 screenshare_ _ .xml 映射，将第二个 cameraVoip_ _ .xml 与第一个 screenshare_ _ .xml 映射，等等。我不知道在某些情况下它是否会中断（对于我看过的几个 Adob​​e Connect 录音来说似乎没问题，但也许那是因为人们总是共享屏幕）。

Answer 3

根据弗兰克的回答，我创建了一个工具来解析 adobe 连接下载的 zip 文件的 XML 文件并输出单个.mkv视频文件。它用于ffmpeg创建视频文件并合并演示者的屏幕共享和相机。当他们/演示者打开他们的麦克风时，它实际上添加了观众的声音。

这是该项目的链接： https ://github.com/ali-em/AdobeCollect

Answer 4

我在 adobe connect 中做了一个使用原始记录器的应用程序，然后所有Admin、非 Admin和Guest用户都可以使用记录模式。

按照Adob​​e Connect Record中的简单安装说明进行操作

如何使用

1. 打开您的网络浏览器并单击网络研讨会链接
2. 将显示一个控制台页面，然后键入 yes 或y然后按 enter。
3. 这是结果：

Answer 5

在 Connect Central 的录制列表中，有一个脱机链接。这将在您的本地计算机上创建录制的 FLV。不幸的是，创建此视频所需的时间与播放录制所需的时间一样长。遵循应用程序提供的指导以获得最佳质量。

然后，您可以将 FLV 转码为您喜欢的格式。

您必须是录制的会议的主持人或已将录制内容移至内容库。
