By the way, Pablo, your issue
https://www.mail-archive.com/ntg-context@ntg.nl/msg88204.html was also
solved in the last upload. Unfortunately it will probably not help you,
because Acrobat no longer supports this.
\useexternalsoundtrack
[myaudio][audio.mp3]
\checksoundtrack{myaudio}
\goto{PLAY SOUND}[StartSound{myaudio}]
But, you can use renderings instead:
\useexternalrendering[myaudiorendering]
[audio/mp3][audio.mp3][embed=yes]
\definerenderingwindow[audiowindow]
[width=0sp, height=0sp]
\definelayer[resources]
\setupbackgrounds[page][background=resources]
\setlayer[resources]{\placerenderingwindow[audiowindow][myaudiorendering]}
\goto{PLAY SOUND}[StartRendering{myaudiorendering}]
This is basically the example from "/back-swf.mkiv". Works in Acrobat.
And one can use either of the three possible file methods (embedded,
external, URL), not just external files. The layer is so that the empty
frame doesn't interfere with normal page content. No frame is drawn when
both dimensions are 0, not sure if that is a behaviour one can take as
granted. But currenntly the dimensions can't be zero.
Hans, I would omit the check for 0 dimensions of rendering window (as
already noted in the source, it is useful for sound). See patch below.

Sorry, should have shared the link at the first place.
https://dspace.cvut.cz/handle/10467/95065
(PLNY_TEXT) links to the full text.
(PRILOHA) is almost all files I had for the thesis. Most notably the
testing files I used. (Some were handcoded, so no sources, but these
should be readable in text editors).

Currently, only attachments are added as "embedded files" (either as
"hidden", ending up in /EmbeddedFiles, or as "annotation" ending up as
/FileAttachment annotation).
Maybe "codeinjections.embedfile" can have the option to force the
reference, so that the file also ends up in /EmbeddedFiles? Should it be
default for all \externalrenderings?
My try:
https://github.com/contextgarden/context-mirror/commit/681c36d0ecfd30c05ed588eb0f37a06dd19f3492
(the full file can be located by clicking on the three dots after the
file name, then "View file" and then "Raw", resulting in:
https://github.com/contextgarden/context-mirror/blob/681c36d0ecfd30c05ed588eb0f37a06dd19f3492/tex/context/base/mkxl/lpdf-wid.lmt,
Patch can be obtained by adding .diff to the URL:
https://github.com/contextgarden/context-mirror/commit/681c36d0ecfd30c05ed588eb0f37a06dd19f3492.diff
I will probably not keep the commit on GitHub forever, it just seems
like a nice way to send quick patches -- it is visual and allows full
file/patch download. So this time full patch also included below for
future reference.)

[NTG-context] Strange new behaviour of the mailing list
Hi all, I noticed that beginning July 27th, the messages distributed by the ConTeXt mailing list appear to be from Mailing list for ConTeXt users without the actual name of the sender appearing. It may be dependent on the mail client I am using (Mail.app on MacOS 11.4), but I wonder whether something has changed on mailing list server, and whether if there is something I can do to have the old behaviour (which was convenient when one wanted to follow up mails from some specific contributors).

[NTG-context] multimedia PDF in ConTeXt
Hi Michal and Hans, many thanks for your patch to fix multimedia objects in PDF and your extremely interesting and in-depth explanation about multimedia in PDF. Many thanks to Hans for the release of an updated latest with also updated documentation. Although I don’t read Czech, just out of curiosity, is your bachelor thesis available on the net, Michal? Thanks to theses.cz, I found https://is.muni.cz/th/t8qpp/DP_Vlasak_Michal_2015.pdf (only a name coincidence, I guess). Using your sample, I have two questions: \starttext \setupinteraction[state=start] \useexternalrendering[myvideo][video/mp4][video.mp4][embed=yes] \definerenderingwindow[myrenderingwindow] [width=\textwidth, height=\textwidth] \placerenderingwindow[myrenderingwindow][myvideo] \stoptext Is there no way to have the video as an embedded file in the PDF document? (I mean, that the file is listed when the attachment panel is displayed.) The second question is addressed to Hans: would it be possible that \placerenderingwindow could have another option and text as in \framed? A workaround would be to add a layer, but too complex only for adding usage instructions for the media usage.
