    Default Live rtmp with image overlay

    Hello All. I wonder is it possible to implement the following feature using wowza.

    I have rtmp streams that are publishing via wowza. I need to modify stream (add several pictures) depending on condition. Condition should come via post or get requests.
    Example: for stream with 123 I should add transparent image1 to upper left corner and it should be visible from 2 to 3.5 sec, then image2 from 5.5 to 8.3 sec, etc.
    Info about time shifts and image names comes via http post in parallel with translation. Could anybody help me what API/modules/etc should be used to implement such feature.

    As I understand I need:
    - ability to modify stream by id/name (add images over main picture)
    - listener that indicates current frame or current second or something like this
    - ability to transfer conditions that should be applied to stream via http.

    The common idea is similar to video with subtitles. We have video with subtitles and start publish both of them. As a result we have live translation with overlays that should appear|disappear at proper time.
