我编写了以下Python脚本以将Adobe 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.

说明脚本的工作方式：
假定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，以下载一些zip存档，其中包含大量音频和视频文件以及一些.xml文件。例如，https://my.adobeconnect.com/p6vwxp2d0c2e/output/p6vwxp2d0c2e.zip?download=zip可以包含：

要合并它们，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：映射第一个仅用于音频的输入文件。-map 1:v:0：映射仅用于视频的第二个输入文件。-shortest：在cameraVoip_1_11.flv和screenshare_2_10.flv长度不相同的情况下，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，如果存在多个：
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。这样可以使用正确的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，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，然后映射第一个cameraVoip_ _ .xml第一个screenshare_ _ .xml，第二个cameraVoip_ _ .xml，第一个screenshare_ _ .xml，依此类推。我不知道如果在某些情况下会中断（对于我看过的几对Adobe Connect录音似乎没问题，但这也许是因为人们总是共享屏幕）。
答案 2 :(得分：0)
在Connect Central中，在录制列表中，有一个“脱机”链接。这将在本地计算机上创建录制的FLV。不幸的是，创建此视频只需录制视频即可。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。
您必须是已录制会议的主持人，或已将录制内容移至内容库中。
