I'm considering my options for implementing a VOD service. Until recently my choices seemed to be either Wowza or Darwin, but now I discovered VLM, which looks really cool.
I am going to stream MPEG4 H.264 video with AAC audio. I'm probably going to use the RTSP protocol, but I'm willing to use HTTP as well (after reading this article).
Can anyone comment on his or her experiences with VLM? How does it compare to Darwin or Wowza? Is it stable and worthy of production use? Are there any limitations or performance problems?
