This is the first version of my podcasting setup that I’m relatively happy with as it is clean without too much things going on. I’ve used this for Corner Geeks and some Tech Talk Coffee Shop episodes.
An alternative to LineIn is Audacity (enable “Software Playthrough” in the Transport menu and click “Start Monitoring” in the input device) or LadioCast but LineIn is the simplest method for this setup. For Windows and Linux users, the Audacity method should work just fine.
So a couple of weeks back we had the honour of live streaming of Ran8adidas (the 8th year anniversary celebrations of Ranoadidas.com) at the International Convention Center (ICC). We share with you how we managed to get mobile video in the field with the ability to add overlays and mix the audio source with any audio source while at the same time live streaming and recording it.
MacBook Pro line-in port to receive sound from the mixer
A USB sound card to be used as audio out for monitoring
Soundflower was used as extra audio devices to aid the transfer of audio from audio sources to audio outputs
LadioCast (free) for audio mixer/switching between mixer and iOS device audio
uStream.tv (free) to stream and record the live video and audio
The video quality wasn’t great and it was a trade-off between faster frame rates vs better image quality and resolution which were limited factors of the WebCamera application (192×144 vs 480×360, but I’m not sure to measure the frame rate). We decided on better image quality as it would be made worse by the spotty 3G connection
We tried using uStream Producer (free) but it was inconsistent as it dropped after 30 seconds. I wonder if this could be due to the 3G reception.
If you have an Android device you can use IP WebCam (free) to stream the video and audio from the device to a computer. I used 2 different instances of VLC (free) to play the video and audio. The video could then be captured using CamTwist and the audio controlled with LadioCast
We experimented with PocketCam for iOS ($4.99) paried together with the PocketControl (free) client software but the delay in video and audio was too great, ~10 seconds.
This week @mfirdaus and I talk about this week’s WWDC 2011. We will split this in 3 parts: Lion, iOS5 and iCloud as the discussion got pretty long. If you want to watch the video of the keynote click here but also do check out Justin Lee’s keypoint summary of the keynote or just refer to Apple’s what’s new section for their info about Lion.

Corner Geeks Episode 4 is live and this week we’re talking about New Media and give an introduction to Live Streaming. In the future we will cover Live Streaming in more details including the setup we used for live steaming the Ran8adidas event at ICC at the end of June.
Search for gstreamer lame plugin: "apt-cache search gstream lame"
Installer the gstreamer lame plugin: "apt-get install gstreamer0.10-plugins-ugly-multiverse" (this may change, just the search results from the previous steps)
Start the Icecast server with the following command (this combines starting a Icecast server and sending audio via a source client all in one command
"gst-launch pulsesrc ! audioconvert ! lame quality=9 ! shout2send mount=/listen.mp3 port=8000 password=YourPass ip=ServerIP"
You can change the mount, port, password, ip values depending on your setup.
The Icecast server is now up and running (assuming there are no errors / typos) and this will stream any audio playing from the device.
