user11782: I want to live stream an event on YouTube with my DSLR. Will I need a HDMI capture card? If yes can you please list a few inexpensive ones. 
Also, please mention if there are any other ways for me to do this.
Thanks.

user10931: Yes, you will need an HDMI capture card.  If you have a modern Mac, you can make do with this $145 device that plugs into its Thunderbolt port: https://www.blackmagicdesign.com/products/ultrastudiothunderbolt/techspecs/W-DLUS-04
