You may want to reconsider your pixel format, and whether that's really required for the video content you are presenting. If "anything" is fine, just add "-pix_fmt yuv420p" to your ffmpeg output options (or experiment with other 8-bit formats such as yuv444p).
with yuv420p it works fine !
Alternatively, you might be able to upload a separate preview image. I can't recall whether Facebook offers that
as far as I know that's not possible in Facebook.
