Yesterday's xiph.org thread had the same discussion - for live-streaming, encoding is the bottleneck. If the encoder drops frames, all recipients drop frames. - for other purposes, decoding is likely the "bottleneck", although even then: the slower and more CPU intensive an encoder is, the more times a video has to be downloaded and viewed to "break even" through the "savings" on the decoder side. So there still is a trade-off to be made with how slow an encoder is allowed to be.
