如何将Adobe Connect录制导出为视频？

Question

我有指向录制会议的链接，如何从这些会议导出视频？

Answer 1

Click of the >登录到您的Adobe Connect帐户然后单击链接上的recording

• Click recording

1. Click“Recordings”链接(屏幕右侧)上的My Meetings
2. Click单击“Name”列中的链接并复制“
4. ”-例如，将其添加到新的浏览器选项卡中，然后在URL末尾添加以下内容：output/filename.zip?download=zip
5. Your
6. 应类似于此示例，

Answer 2

我编写此Python脚本以将Adobe Connect录制导出为视频：

'''
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.

关于脚本工作原理的说明：

假设Adobe Connect ID为p6vwxp2d0c2f，即URL为https://my.adobeconnect.com/p6vwxp2d0c2f。您可以在URL的末尾添加/output/p6vwxp2d0c2f.zip?download=zip，以下载包含一堆音频和视频文件以及一些.xml文件的压缩归档文件。例如，https://my.adobeconnect.com/p6vwxp2d0c2e/output/p6vwxp2d0c2e.zip?download=zip可以包含：

如果any.

• screenshare____.xml包含音频+网络摄像头，则
• cameraVoip____.xml包含音频+网络摄像头。

要合并它们，您可以使用ffmpeg (我从Oliver Wang / Yannick Hold-Geoffroy / Aaron Hertzmann那里获得了ffmpeg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

其中：

• -map 0:a:0：映射仅用于audio.
• -map 1:v:0：的第一个输入文件映射仅用于video.
• -shortest：的第二个输入文件在cameraVoip_1_11.flv和screenshare_2_10.flv长度不同的情况下剪切音频或视频。

如果您想保留摄像头视频，并将其放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，如果存在多个one：

用户可以查看cameraVoip____.xml / screenshare____.xml来获取音频/屏幕共享视频开始的时间戳。这允许使用正确的cameraVoip____.xml映射screenshare____.xml。

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

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

否则，另一种方法可以是排序cameraVoip____.xml / screenshare____.xml，然后将第一个cameraVoip____.xml映射到第一个screenshare____.xml，第二个cameraVoip____.xml映射到第一个screenshare____.xml，依此类推。我不知道在某些情况下它是否会中断(对于我看过的两个Adobe Connect录制似乎是可以的，但这可能是因为人们总是共享屏幕)。

Answer 3

基于Franck的回答，我已经创建了一个工具来解析adobe的XML文件，连接下载的压缩文件，并输出单个.mkv视频文件。它使用ffmpeg创建视频文件，合并屏幕分享和演示者的摄像头。当观众/主持人打开麦克风时，它实际上增加了观众的声音。
