I’ve done this before, but not sure of the method to make it work. Video is in .MP4 format hosted at my website. Should also work from LSC Freight shed but you might need a web.config file to tell browsers how to render the file.
Step 1 - Host the .mp4 file somewhere… This one is at http://lsc.cvsry.com/Video/
Step 2 - Press the Insert / Edit video button on the top line of LSC’s editor
Step 3 - Paste the entire URL of the video into the Source field on the General tab of dialog box that pops up. I don’t fill in anything else or change the defaults.
Step 4 - Press OK.
Step 5 - Immediately Press POST Topic. Do not make any changes anywhere in the message, or the video may not play. I’vve also found that going back and editing the message will kill the video.
Result:
