Send big files by mail with android


i have installed Seafile on my Debian. I have installed the android client on my phone.
I have big video on my phone and i send specific video on my seafile cloud.

Can i share video like GOOGLE DRIVE ?
When i filmed a video, i want to send them or url of this video to my family (downloading or streaming). Is it possible ?
Maybe integrate seafile on my email client or with a button share to another (email, sms, mms…) ?
