Copying the template offered by A.Grahn at the following post almost exactly,
Embedding videos using media9,
I ran the code below in pdfLaTeX:
\documentclass{article}
\usepackage{media9}
\begin{document}
The video should appear just below.
\includemedia[
width=0.4\linewidth,
height=0.3\linewidth,
label='firsttry',
addresource="C:/_Book/_Website/40631-H.264.mp4",
activate=pageopen,
flashvars={source="C:/_Book/_Website/40631-H.264.mp4"}
]{This is the poster text}{VPlayer.swf}
The video should appear just above.
\end{document}
I got no errors, and the resulting document looked just as expected, showing the words "This is the poster text" bounded by the text expected above and below it, but the video did not play. Instead I see only a cursor that's shaped like a magnifying glass which, when one clicks the poster area with it, causes that area to get bigger (as the cursor would imply), but does not play the video.
The video does indeed reside in the folder listed, and plays fine when one double-clicks it directly. It is apparently H.264 - at least that's the codec I chose for it in Handbrake, and MediaInfo tells me that it's "MPEG-4(Base Media / Version 2_: 218 KiB 2s 200ms" and further that it's "638 Kbps, 640*480 (4:3) at 15 fps, AVC ([email protected]) (CABAC / 4 Ref Frames)".
I get the very same (lack of) results whether or not I place the path names in quotation marks. Including &autoplay=true among the flashvars also did not change the results. I also get the same (lack of) results whether or not I specify VPlayer.swf or VPlayer9.swf.
Footnote: This surely doesn't matter, but I just discovered there has to be a line skipped after "The video should appear below" for the results to look as expected. (In posting this, I had collapsed the blank lines to make the code easier to read.)
