如何将Adobe Connect录制导出为视频？

我有到录制会议的链接，如何从中导出视频？

在Connect Central的录制列表中，有一个“制作脱机”链接。这将在本地计算机上创建录制的FLV。不幸的是，创建此视频所需的时间与播放录制所需的时间相同。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转换为您喜欢的格式

您必须是已录制会议的主持人，或者已将录制内容移动到内容库中

登录您的Adobe Connect帐户

单击会议>我的会议

单击录制的链接

单击“录制”链接（屏幕右侧）

单击“名称”列中的链接

复制“用于查看的URL”-例如

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

您的URL应该类似于此示例

我编写此Python脚本是为了将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.

• xml包含音频+网络摄像头（如果有）
• screenshare_u;.xml包含音频+网络摄像头（如果有）

要合并它们，可以使用

ffmpeg

（我使用了Oliver Wang/Yannick Hold Geoffroy/Aaron Hertzmann提供的

ffmpeg

命令）：

其中：

• -映射0:a:0

  ：映射仅用于音频的第一个输入文件

• -映射1:v:0

  ：映射仅用于视频的第二个输入文件

• -最短的

  ：如果cameraVoip_1_11.flv和screenshare_2_10.flv的长度不相同，请剪切音频或视频

如果要保留网络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映射到正确的屏幕共享____;.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。这允许使用正确的cameraVoip__;.xml映射screenshare__;.xml

例如，在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，第二个cameraVoip______;.xml与第一个screenshare（对于我看过的几段AdobeConnect录音似乎还可以，但可能是因为人们总是共享屏幕）。

1.将下载的录音解压缩到目录2.下载并安装“FLV编辑器Lite”3.导入>FLV并选择您提取的“screenshare…FLV”文件。4.导入>FLV并选择“audio…FLV”文件（或您提取的“voip…flv”）。5.将屏幕共享项目拖到时间线的“视频”区域6.将音频或voip项目拖到时间线的“音频”区域7.选择导出>flv并为文件命名。您的链接不可访问，您是否有指向flv编辑器Lite的其他链接？flv编辑器Lite的网站“现在已经不存在了，还有其他应用程序可以这样做吗？

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" \
