You can do all that with the help of GStreamer but you will nonetheless
still need to write some code to glue everything together. There is not
ready-made solution for this (yet) but all the buildings blocks exist.
For receiving and transcoding the HLS stream you can use the standard
GStreamer elements, like uridecodebin (for receiving) and the relevant
encoders and muxers to generate the MP4 fragments.
For creating the DASH manifest and serving it you have a few options,
take a like at gst-streaming-server and these bugs here:
