No, and most likely won't be in as of the current form. > Are there examples of drivers that already do this type of thing? Depends on what you need to handle. The biggest challenge would be a stream with variable bitrates. Currently, ALSA framework assumes the constant bitrate streams. If your mpeg stream is also in a constant bitrate, you may handle it simply as a special form of PCM, for example, as AC3 does right now.
