    Default Will transcoder adapt to format changes while streaming?

    Hi,
    I am considering the Wowza Transcoder add-on to process the IP stream from a video server that will be streaming a video channel derived from playing back files sequentially. Does Wowza figure out the stream content when it sees it? Or does it all have to be pre-configured somewhere to match the stream? In particular, can the transcoder handle it if the stream changes between, say MPEG-2 480i and MPEG-2 720p?

    What if the stream can also change codecs? e.g. transition from MPEG-2 to H.264? Maybe switching SD/HD at the same boundary?

    Will the transcoder die? Transition successfully but with an ugly transition? Or, best of all, not even glitch?

    Default

    Switching profiles, frame size, etc of the video should be OK. Switching codecs will not work. Switching audio sample rate or number of channels will not work.
