Schaller: The long journey towards good free video conferencing

Christian Schaller writes about why we don't have good video calling yet and what is being done to get there. "In addition to the nitty gritty of protocols and codecs there are other pieces that has been lacking to give users a really good experience. The most critical one is good echo cancellation. This is required in order to avoid having an ugly echo effect when trying to use your laptop built-in speakers and microphone for a call. So people have been forced to use a headset to make things work reasonably well."
