Hi,
Is multi stream recording currently supported, and if so, how does it work? Can the flash media server merge multiple streams into one and record it?

You can record and play back multiple streams.

The OpenTok archiving API supports two types of archives:
Per-session archives, in which each individual stream that is present during the recording is recorded
Per-stream archives, in which you select the individual streams to recordWhen you play back the archive, you can playback each of the individual streams that were recorded.

You can also set up a session to generate an auto-produced multiplexed stream. You can record this stream to your archive. There are two types of multiplexed streams:
Timeout-based streams, in which the multiplexed stream switches between published streams on a set intervalActivity-based streams, in which the multiplexed stream switches between publishers based on audio activity

Thanks for the detailed explanation.
Is the multiplexed stream a single stream merged on the server side, or is it simply a client-side script which switched between the received multiple streams?Is the activity-based stream also available in the love mode? I have asked this question about switching between the streams based on the active audio, but the answer was negative: http://forums.tokbox.com/post?id=5410101

1. The multiplexed stream is a single stream generated at the server from multiple input streams. Both speech activity detection and video multiplexing are handled at the server.
2. We don't yet have an API to notify the developer about the current "active" publisher. If you think this can be an useful feature for your application, please submit an API feature request together with a brief description of your use case at http://forums.tokbox.com/?forum=193377.

Question:
How do I download the videos for an archive that has multiple streams? do I get multiple FLV files or one file with the streams multiplexed?
Downloading and playing back archives with a single stream did not pose any problems, but I can't figure out how to do it with an archive that has multiple streams, I'm using the ruby server side API, and the resources attribute of the manifest has a group of videos in addition to to timeline objects, and downloading a single video from the resources produces a corrupt FLV file.
Any help or guidance would be really appreciated.

It will be multiple FLV files. What do you mean by a corrupt FLV file? We store the raw rtmp packets that are received by the server.
