DirectShow RTMP streaming filter

hi, I bid this project as I have good experience in directshow filter developement. Also I have worked in streaming applications on encoding side. Worked in HLS streaming, Adobe smooth streaming on the encoding/transcoding ffmpeg streamed Transport stream to fragmented mp4 boxes in c++ language. The ts and mp4 with parsing is done in both c++ and C#. h264 and aac basic header parsing ( upto NALU to find duration and frame type are done). Had done time based and I frame based segmentation/fragmentation of these codecs. I have few questions here, - What is input to the filter - is it a rtmp stream of h264 and aac - Is mp4 container is used - Is the funtionality of the filter is ONLY to pause/resume graph based and internal based and redirect to Adobe/wowza server or any trancoding is needed
