How can I stream live through my camcorder?

Episode 1186

Nick from Santa Cruz, CA

Nick has a camcorder with HDMI out and he wants to know if he can run Wirecast with a tablet. Leo says probably not. He'll need a computer because tablets don't have HDMI in, only HDMI Out. He'd also need HDMI live as a feature in the camcorder. If it will only be live in playback, then it won't help. Do any notebooks have HDMI? Leo uses Canon Vixia's with a Blackmagic converter to run into the computer. Imogen also makes an HDMI Input card.

Why does my video stream buffer so much?

Kathy from Santa Clara, CA

Kathy watches Leo online through UStream and is frustrated because it buffers a lot. Leo says it's on UStream's end, and he can't do much about it. He also streams through BitGravity and Justin.TV, so she could try one of those. Also, choosing the lower resolution from BitGravity could help. Kathy should also look at her bandwidth online. If she only has 1.5 Mbps down, for instance, she will continue to have a rough time with streaming. It could also be a bad modem. She should ask for a new modem or buy her own. She could first try rebooting both the modem and router.

JR from Rancho Cucamonga

Jay is trying to do some live video streaming with a limited signal 4G using the Livestream Broadcaster, and is wondering if a signal amplifier would help. Leo says not really. He needs high speed signal in the area. Leo used to use the Live U backpack that used 8 different cards to bond together and get a better signal by marrying multiple signals, but it wasn't cheap.

How does streaming work?

Episode 945

Tony from Kentucky

Tony was streaming while he's on the road and the TV show stops every so often. Leo says that's called "buffering," which is when the stream has to stop for a second while it waits for all the data to be downloaded in order so it can continue. Sometimes a packet of data will get lost or delayed, so the media has to stop and wait for the data packets to "catch up". It usually has to load 30 seconds of the content before it can start playing again. If it's starting and stopping all the time, that usually points to an internet bandwidth problem.
