This project contains 3 main components
- Recorder which records shows from HDHomerun devices on the local network in mpeg2
- Upnp server which serves shows to DNLA clients
- cleaner which strips commercials from shows and compresses them to a reasonable size
The recorder uses data in the XMLTV fromat from Shedules Direct to shedule recordings and then record them using IP network based HDHomeRun devices from silicondust (and others like HDPVR if you want). The recorder simply takes a list of show names and then finds/schedules all "new" episodes for that show. Guide data is downloaded nightly and used to update the currently scheduled recordings
The cleaner walks a top level directory recursively looking for recorded content. For each show it finds it uses comskip to identify commercials in the show and the simplyl cuts out the byte ranges corresponding to the commercials. This works because the mpe2 format is resiliant to parts of the streams being removed. Once the commercials are stripped out the cleaner them compersses the show using handbrake and places them in the final directory for viewing
The UPnP server servers the recorder shows to DLNA clients. It has a few extra features like identifying which shows have already been watched. I use multiple instances of the server and have each family member use a different instance so that we can each see which shows we have already watched/not watched. In addition the server provides a "virtual" directory for new content where only those shows which have not already been watched show up
