I wanted to activate loop until stopped in playback tab but unable to find a way

[matt-song27]

Hello,

I was able to create a new slide and add a video to the slide. I also wanted to make the video have loop until stopped option in playback tab activated using python-pptx. Unfortunately, I was unable to do so. Is there anyone who was able to make it?

Best, Matt

Not particularly good with the XML side of things but this seems to do the trick...

from pptx import Presentation
from pptx.oxml.xmlchemy import OxmlElement, qn

presentation = Presentation("video.pptx")
for slide in presentation.slides:
    try:
        pic = slide._element
        rId = pic.xpath('./p:timing/p:tnLst/p:par/p:cTn/p:childTnLst/p:video/p:cMediaNode')[0]
        rId2 = pic.xpath('./p:timing/p:tnLst/p:par/p:cTn/p:childTnLst/p:video/p:cMediaNode/p:cTn')[0]
        rId.remove(rId2)
        jj = OxmlElement("p:cTn")
        jj.set("repeatCount","indefinite")
        rId.insert(0,jj)
    except:
        pass
presentation.save("videoloop.pptx")

@bowespublishing Thank you for answering. I was able to implement it thanks to your help. I needed to make it work with multiple videos on a slide as below.

from pptx import Presentation
from pptx.oxml.xmlchemy import OxmlElement, qn

presentation = Presentation("video.pptx")

for slide in pres.slides:
    try:
        pic = slide._element
        videos1 = pic.xpath('./p:timing/p:tnLst/p:par/p:cTn/p:childTnLst/p:video/p:cMediaNode')
        videos2 = pic.xpath('./p:timing/p:tnLst/p:par/p:cTn/p:childTnLst/p:video/p:cMediaNode/p:cTn')

        if videos1 and videos2: # if at least a video is added
            for i in range(len(videos1)):
                rId = videos1[i]
                rId2 = videos2[i]
                rId.remove(rId2)
                jj = OxmlElement("p:cTn")
                jj.set("repeatCount","indefinite")
                rId.insert(0,jj)
        except:
            pass

presentation.save("videoloop.pptx")

Thank you for this. I think in md2pptx I can expose this via the HTML video autoplay attribute.
