I am having a similar issue to a prior forum (\includemedia does not play video but remains blank).
I would like to have a video in my pdf that plays when you click on it. When the video is not playing it should show a figure. When I compile my pdf I do get a figure that I can click on, but it turns blank when I click on it, and no video plays. I don't get any errors either. This is my code:
\documentclass[12pt,landscape]{article}
\usepackage[]{media9}
\begin{document}
\includemedia[activate=pageopen, width=1.0\textwidth, addresource=./Videos/myVideoH.mp4, flashvars={source=./Videos/myVideoH.mp4}]{\includegraphics{./pathCB.png}}{VPlayer9.swf}
\end{document}
I believe I took into account all the suggestions mentioned in the prior forum. For instance, I have the same issue whether I use {VPlayer9.swf} or {VPlayer.swf}. Moreover, I downloaded a new .mp4 file that was listed as codec h.264, and the problem persisted. Finally, I converted the .mp4 file to .flv, and still the problem persisted.
In all these cases, upon running pdflatex, I received no error to produce the .pdf file, and the image showed up with a play button superimposed, but I could not click on the image and begin the video.
Along the same lines, I am using a stock video now to get the general syntax working. However, I would ultimately like to record my own video and use that instead. So, if this problem is because of pickiness of the format of the video being used, I would simultaneously be very grateful to hear any advice about how I should record my video to keep the syntax working.
(I am using OS X 10.9.5.)
Thank you for any of your advice!
