Media codecs are a little different because there is a significant cost to replacing hardware that only supports the old standard. It seems to me that AAC is becoming pretty ubiquitous and probably will be the go to standard for the next 10-20 years. We are also at a point where the vast majority of users aren't going to notice the difference between a 100kbps MP3 vs AAC stream, which is going to be less than 1% of an he stream, so there is little incentive to innovate by the players with the deepest pockets. Until network capacity is free (or at least cheap compared to to the cost of CPE) pipelines based on uncompressed media are not going to be a thing outside of the production end of things. For source tar balls though there is basically 0 cost to switching. Since you can download a new compressor in under a minute and should be able to assume that your users are pretty sophisticated. The incentives are similar to media in that cost transfer has to be weighed against the cost of CPE, except that since users supply the CPE the cost is effectively 0 and compression will probably always make sense.
