I have used the built-in file recorder which saves a live stream to a file output stream. We currently have a custom recorder that is capable of writing the streams to blob storage, we have used the FLVUtils class to write it to storage, but the problem that we are facing is, with the FLV container, we are not able to stream that back through wowza for playback (due to obvious reasons: missing boxes/atoms etc). Need help in getting the amf packets written to an mp4 container by properly writing the boxes and the data. Right now I'm trying to use the MP4FragmentWriter to write atoms and the packet data to the output stream. Any help in this area is appreciated.
