Well, the link you provided (https://mailman.ntg.nl/pipermail/ntg-context/2021/103023.html) is from February 2021: https://opensource.adobe.com/dc-acrobat-sdk-docs/acrobatsdk/pdfs/acrobatsdk_jsapiref.pdf Here is the guide to developers (from the same date): https://opensource.adobe.com/dc-acrobat-sdk-docs/acrobatsdk/pdfs/acrobatsdk_jsdevguide.pdf > Anyways, I thought that the culprit is that you only specify the > rendition (what to play) and not screen (where to play): > > > function GoToFirstSlide(label) { > this.pageNum = 0 ; > var rendition = this.media.getRendition(label) ; > +var screen = this.media.getAnnots({ nPage: 0})[0]; > var player = app.media.openPlayer({ > rendition: rendition, > + annot: screen, > }); > } > > But as it turns out, while the screen query succesfully returns an > object, the rendition query returns null. > > The PDF 1.7 standard specifies that the name (/N) of Rendition PDF > object should be Unicode, but that doesn't seem to make it work either, > as does deleting the name of the media clip (which was the same). > > (But I now get "Invalid arguments" error for the "app.media.openPlayer" > call, which is kind of expected.) > > Can you confirm, that "rendition" is null on your side as well? > > console.println(rendition); > console.println(screen); > console.show(); I get exactly the same results: screen object, but null rendition.
