Choosing the other two buttons to view those videos gives an error, something
like "No video with supported layout and MIME type found". The buttons for
downloading work as expected.
When I copy the index.html for this web page and the files mentioned in that
file in a folder (everything is in one folder) and use file://
<path_of_folder>index.html in Firefox all colors look good. I can view all
videos and I can select positions in those videos.
The only difference in these two cases is that the files go through apache to
Firefox or come directly from the disk.
In both cases I used Page Source in Firefox to download index.html. I compared
these files and apart from obvious differences in locations of the referenced
files, they are the same.
Any clues?
