Assume that the Adobe Connect ID is p6vwxp2d0c2f, i.e. the URL is https://my.adobeconnect.com/p6vwxp2d0c2f. As you mentioned in the question, you can add /output/p6vwxp2d0c2f.zip?download=zip at the end of the URL to download some zip archive containing a bunch of audio and video files as well as some .xml files. E.g., https://my.adobeconnect.com/p6vwxp2d0c2e/output/p6vwxp2d0c2e.zip?download=zip could contain:

- cameraVoip__.xml contains the audio + webcam if any.
- screenshare__.xml contains the audio + webcam if any.
To merge them, you can use ffmpeg (I took the ffmpeg commands from Oliver Wang / Yannick Hold-Geoffroy / Aaron Hertzmann):
ffmpeg -i cameraVoip_1_11.flv -i screenshare_2_10.flv -c copy -map 0:a:0 -map 1:v:0 -shortest output.flv
where:
-map 0:a:0: map the first input file to be used just for the audio.-map 1:v:0: map the second input file to be used just for the video.-shortest: cut the audio or video in case cameraVoip_1_11.flv and screenshare_2_10.flv don't have the same length.
If you want to keep the webcam video and place it in some corner of the video screen sharing:
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
Regarding mapping the cameraVoip__.xml to the correct screenshare__.xml, in case there is more than one:
One could look at the cameraVoip__.xml / screenshare__.xml to get the timestamps of when the audio / screen share video began. This allows to map the screenshare__.xml with the correct cameraVoip__.xml.
E.g., in https://my.adobeconnect.com/p6vwxp2d0c2f/output/p6vwxp2d0c2f.zip?download=zip, from cameraVoip_1_11.xml, line 21:
<String><![CDATA[Thu Feb 07 21:11:23 2019]]></String>
Otherwise, another way could be to sort cameraVoip__.xml / screenshare__.xml, then map the first cameraVoip__.xml with the first screenshare__.xml, the second cameraVoip__.xml with the first screenshare__.xml, etc. I don't know if it'd break in some cases (seems to be ok for the couple of Adobe Connect recordings I looked at but perhaps that's because people always share screens).
I wrote some python script to automate the process (code repo: 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"
Please email Franck Dernoncourt <[email protected]> if you improve this code.
