AJA IO HD to live web stream
by Rich Rouleau on Apr 14, 2009 at 7:24:21 pm

Just wondering if anyone has used the AJA IO HD with a service like ustream.tv.

We are looking to do some live streaming, of SD and HD formats and the AJA box attached to a MacBook Pro seems like the ticket.

Thanks in advance!

The ioHD will not encode to a web friendly codec in real time, but it will take your HD feeds and turn them to SD in either SDI/embedded or separete analog YUV/audio and send them to another device that is ready for real time web encoding. For that the ioHD will work, but it will not provide a streamable video signal.

You should look for a box that will do this in real time such as NewTek's Tricaster.

I understand the ioHD will not encode for web. http://ustream.tv /Watershed is/has the encoder and their encoder will ingest DV source.

I was more so wondering if anyone has used the ioHD to feed the source to such a service through firewire.

I tested this a while back and it worked okay.

I went from my Kona3 System HD 1080i seq, downconverted to SD SDI out to a MBP w/ the IoHD. Opened up Quicktime Player>File> New Movie Recording, open up prefs set the IoHD as the source, then choose H.264 as the recording mode. (I think you need to set the record prefs before you open the New Movie Recording)

This will record a realtime H.264 movie. Don't have many options but it is there.

Rich,

I do this every Friday night. I used to use Stickam.com and my set up was 1080i into sdi 1, HDMI out to monitor and signal was 525 1 into stickam. It had to be 525. We had problems with stickam and last wek switched to Ustream. Ustream can take the 1080i signal with no down convert. So now it's 1080i straight through and it works fine. Ustream has a settings window like all do. It's flash settings. Ustream has presets for DVC Pro 720 and 1080. I tried them but I couldn't get a signal to pass so I just selected 1080 and it worked fine.

Rich,

I also stumbled upon this program: http://www.allocinit.com/index.php?title=CamTwist

It allows you to switch cams and add graphics etc. Kind of a poor mans switcher but with my IOHD and ISight, I now have two sources (make that 4 by adding component and composite Switched in control panel during preview) and more with USB.

We are actually using a Sony Anycast for production of the show.

For now outputting to a DVCpro50 shoebox, for recording and for output to our Adobe flash media encoder (firewire). Our show is then run through http://watershed.ustream.tv

Its live right now (if interested)...
http://scad.tv

I was looking at the ioHD so that we have the ability to do HD/SD in a portable appliance.
