Wie kann ich exportieren Adobe Connect-Aufzeichnung als video?

Schrieb ich dieses Python-Skript zum exportieren einer Adobe Connect-Aufzeichnung als video:

'''
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.

Erklärung, wie das Skript arbeitet:

Davon ausgehen, dass die Adobe Connect ID ist p6vwxp2d0c2f, d.h. die URL ist https://my.adobeconnect.com/p6vwxp2d0c2f. Sie können hinzufügen /output/p6vwxp2d0c2f.zip?download=zip am Ende der URL für den download einer zip-Archiv enthält eine Reihe von audio-und video-Dateien sowie einige .xml-Dateien. E. g., https://my.adobeconnect.com/p6vwxp2d0c2e/output/p6vwxp2d0c2e.zip?download=zip enthalten könnte:

• cameraVoip__.xml enthält die audio - + webcam wenn eine.
• screenshare__.xml enthält die audio - + webcam wenn eine.

Miteinander zu verschmelzen, die Sie verwenden können ffmpeg (ich habe den ffmpeg Befehle von 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

wo:

• -map 0:a:0: Karte der ersten Eingabe-Datei verwendet werden, nur für die audio.
• -map 1:v:0: Karte der zweiten Eingabe-Datei verwendet werden, die nur für das video.
• -shortest: schneiden Sie die audio-oder video-im Falle cameraVoip_1_11.flv und screenshare_2_10.flv nicht die gleiche Länge haben.

Wenn Sie möchten, um das webcam-video und legen Sie es in irgendeiner Ecke des video-Bildschirms teilen:

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

Bezüglich der Zuordnung der cameraVoip__.xml an die richtige screenshare__.xml, falls es mehr als einen:

Konnte man sich die cameraVoip__.xml /screenshare__.xml, um die Zeitstempel, Wann die audio - /Bildschirm teilen video begann. Dies ermöglicht das anzeigen der screenshare__.xml mit den richtigen cameraVoip__.xml.

E. g., in https://my.adobeconnect.com/p6vwxp2d0c2f/output/p6vwxp2d0c2f.zip?download=zip, aus cameraVoip_1_11.xml, Zeile 21:

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

Sonst, ein anderer Weg könnte sein, die Art cameraVoip__.xml /screenshare__.xml ist, dann zuordnen der ersten cameraVoip__.xml-Daten mit der ersten screenshare__.xml, die zweite cameraVoip__.xml-Daten mit der ersten screenshare__.xml, etc. Ich weiß nicht, ob Sie würde brechen, in manchen Fällen (scheint ok zu sein für die paar Adobe Connect-Aufnahmen, die ich angeschaut aber vielleicht daran, dass die Leute immer Bildschirme freigeben).
