Adobe To Open Real-Time Messaging Protocol
synodinos writes "Adobe has
announced plans
to publish the Real-Time Messaging Protocol specification, which is
designed for high-performance transmission of audio, video, and data between
Adobe Flash Platform technologies. This move that has followed the opening of
the AMF spec has been
received with varying degrees of enthusiasm from the RIA community."
Flash is open. There is no open source viewer yet, but the specifications themselves have been there long enough.
As long as there are slaughterhouses, there will be battlefields.
May 2008 was when Adobe relicensed it to permit development of viewers.
The big parts not in that spec are Spark (the video codec, which I don't think Adobe CAN open up, I'm not sure it's all theirs) and RTMP. Now it's just Spark.
The AC original poster is a moron.
"You can either have software quality or you can have pointer arithmetic, but you cannot have both at the same time."
On windows, try Foxit Reader. If you must stick with acrobat reader, disable all the plug-ins you don't need. They massively increase the loading time.
Not a sentence!
HTTPHeaders can be as useful as anything else.
It will list the full URL of every html, image, css, js, and flv requested from the server for the current page.
Simply copy the flv URL and paste stright back into the browser ... instant save-as prompt and your done :-)
Spark is just another name for H.263; you can get the spec from ITU. The undocumented proprietary codec is VP6, but ffmpeg has a reverse-engineered decoder.
Um, RTMP is not a chat protocol. It is a protocol for stateful connections with multiplexed streams for downloading large amounts of media with real-time responses and quality of service requirements. It is what the Flash Player uses to download audio and video from servers. See Wikipedia. Next time, look up the topic before spouting off.
I've written code that deals with PDF, both in terms of parsing and rendering it, as well as generating it. PDF is a great format. It certainly doesn't have the difficulties associated with, for instance, PostScript. Adobe's products might have poor performance but this is not due to the file format, which is NOT proprietary but actually quite well-documented.
I have no idea what sorts of crazy things happen inside Adobe's code. Suffice it to say, none of that is mandated by the PDF format.
The block of garbage at the beginning of the handshake is, as far as I can figure out, a bandwidth test. The pattern is intended to be resistant to compression, so as to more accurately measure the real throughput of the client's connection.
