在我这边，ffmpeg 可以很好地处理 cameraVoip__.xml 文件。
我编写了这个 Python 脚本来将 Adobe Connect 记录导出为视频（代码库：https ://github.com/Franck-Dernoncourt/adobe-connect-video-downloader ）：
'''
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"
The script assumes that the .zip files contains screenshare__.flv files, which contain the screen share.
Please email Franck Dernoncourt <franck.dernoncourt@gmail.com> if you improve this code.
