I know that the way to embed an image is by 
but it does not seem to work with the WebM videos. https://www.webmproject.org/ WebM is a video file format that all modern web browsers are able to play by default. WebM files can be inserted into web pages just like ordinary images/pictures can be embedded: upload the file to a web server and the web server does not need any special capabilities for serving them. One of the benefits of the WebM format is that videos can be scrolled without downloading the whole video file before scrolling and the scrolling functionality works with ordinary, mainstream web servers. A video for trying out the scrolling possibilities of a WebM video file: (The file is ~386MiB) https://archive.softf1.com/2015/2015_12_27_ccc_de_Joanna_Rutkowska_Towards_Reasonably_Trustworthy_x86_Laptops.webm On Linux WebM files can be created by nice -n20 ffmpeg -i ./Schooby_Doo_video.mp4 ./Spooky_video.webm # It takes a while to convert, hence the "nice". Thank You for reading my letter & thank You for the answers :-) P.S. I briefly surfed the Fossil mailing list archive at my local computer and I suspect that I asked something similar in the past. The lack of WebM video support seems to be something that I seem to stumble upon repeatedly. _______________________________________________ fossil-users mailing list fossil-users@lists.fossil-scm.org http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users
