v7.3. Embed Videos & Photos fails.

Finally finished upgrading my sites to v7.3.

Cannot embed videos, photos, etc... "embed failed"

ffmpeg.exe is set to 777.

tools > host tools - everything looks OK.

what am I missing?

Everything was working fine prior.

As a follow-up, if I paste a youtube video url or a photo url as TEXT into Timeline, it posts OK.

Why won't embedding the same urls work either in Timeline or via video / photo modules (i'm assuming sounds won't embed either)? I have a functioning embed.ly key in settings > general.

What happens when you paste the YouTube URL in the Timeline?

When I paste the youtube url into the timeline (as text) it posts the video as it should. Same with photo urls.

However, when myself or any member clicks video, photo or sound and chooses embed function (whether in the post to timeline box or via the respective modules to add to their album), the embedding fails in all instances.
