Greetings, all. I'm new to the list and I think that rtmpy might help me
solve a problem, but I'd like to ask some advice from folks familiar
with it.

Problem: at work we stream sporting events using Flash:

vidcam -> Flash encoder -> internet -> CDN server,  and

CDN server -> internet -> end users -> player SWF/Flash plugin/browser

We have been dealing with network issues, and I need to write a tool to
monitor our streams in both directions.

Task 1: make a connection to our CDN, pretend to be an end-user watching
a video, and monitor the flow of incoming packets. My goal is to detect
when the inbound stream gets interrupted. I'm ok with writing code that
monitors a stream and detects interruptions, but I have no clue how to
go about making an RTMP connection to the CDN. My test player connects
to, for example,
rtmp://fml.dca.1C71.edgecastcdn.net/201C71/examplestream and plays the
stream. The code I want to write would do the same thing, just not
display the video.

Task 2: make a connection the the CDN, read an FLV stream off disk, pump
the stream through the CDN as if it were an encoder delivering a live
stream, and detect when the ability to shove packets at the CDN gets
interrupted.


I have been reading through the rtmpy docs looking for ways to do this,
but I haven't made a lot of progress. Could someone point me to the
proper place in the docs that might show me how to do this? I'm not
afraid to do some digging and research, I would just like a nudge in the
right direction. Once I get this puppy working I'll be glad to share the
result with the world.

Sounds like a useful tool!

The client side of things has been slightly left behind the current server api, something which I am working on this weekend. By the end, I plan to be able to use RTMPy as a client to call server side methods, stream video .. generally act like a flash client. I am currently using a default FMS install with the example apps to make this work, once I get to a level of stability, I would love to be able to test/help you get that up and running.

This might take a little bit more work (but not too much), RTMPy will gladly accept an A/V stream but not build/publish one. This is something I would love to get up and running.

The code is probably the best place to start looking tbh. The docs are a little light and *hopefully* the docstrings should help more .. The best place to start might be rtmpy.server as it gives an idea on how to interact with the lower level rtmp apis ..

I am busy this morning (GMT+0) but should around this evening/tomorrow working on this stuff .. jump on IRC if you have any questions!
