I am using the LaTex beamer package to create presentations that contain avi videos. this has been working till yesterday afternoon. since then, none of the pdfs (either newly compiled or old files that used to play the videos) do not play the embedded videos anymore. Sometimes acrobat pro dc freezes, and upon ending its task, the error Acrobat failed to send DDE command pops up. This does not come all the time, its just that none of the embedded videos play upon clicking. What changed since yesterday?

best, matthias

Beware of "auto update"!

Acrobat no longer supports the Flash Player.

Now you must use MP4s ==> https://helpx.adobe.com/acrobat/using/rich-media.html

yeah this is what I suggested, I just thought that this will happen by the end of the year, but it seems that the change happened during that afternoon. I will try to embed mp4s into the pdf via latex's beamer package...which means that I will have to render all videos anew. bummer. but thanks for the hint. gonna try that these days

Update:

- I rolled back the Nvidia drivers, de-installed and re-installed acrobat pro without any luck

- then I tried different settings in the control panel of the graphic card, such as adaptive v-sync, or handing over the anistrope filtering to acrobat (there are a couple of tweaks you need to do in order to get LR6 to use the GPU for calculations, so I assumed this might be the problem here as well), but no luck.

- I also modified the settings within acrobat, such as to use other programs than flash, but that did not help either.

- In another post I read that, if the path to the videos is bad, the video wont play. I knew that this is not the reason here because I have two other pdfs in that folder that used to play just fine. Nevertheless I moved the folder to another partition and tried to play the embedded videos there. no luck either

Flash is deprecated?

no, flash player is 32.0.0453. I re-installed acrobat pro as well as flash player.

The thing is that yesterday during the day I was working on the compiled pdfs and it was working. I did not change any settings in acrobat at that time but tried different things in the multimedia settings without any luck. I suspect therefore that my graphics card settings (RTX 2070), or its driver update from yesterday somehow cause problems. Did anyone see such an effect on embedded avi files in a pdf?
