Have you checked the http options?
https://www.ffmpeg.org/ffmpeg-protocols.html#http
I have no experience, but I could imagine you need the option
"-chunked_post 0". And since you set the Content-Type with curl, you
may need to do so with ffmpeg as well, using "-content_type video/mp4".

Just guessing,
