Uploading .mpg/.mp4 Video Files to WordPress? Be sure they have an audio track embedded

The newest version of WordPress is 4.1 and it keeps getting better and more convenient to upload and embed videos on your website.  Just a note of caution, however!

Be sure your .mpg/.mp4 video files have an audio track or it is likely your video will not be recognized or play in WordPress.

I’m not complaining, just hoping I will save others who may produce videos the trouble of having to rerender their video files with an audio track when they don’t have one.  This isn’t a deal breaker, but it’s also not efficient.  After all, if you have a video, say an animation that is without sound, you shouldn’t have to output an empty audio track, it’s just a little more work and makes the files just a little bigger.  Not a big deal in the whole scheme of things, but then again, in the aggregate, is still is wasteful and a bit annoying.
