= Tvheadend TODO list =

=== Add -l option (easy) ===

Starting Tvheadend with the '-l' option should always allow access from localhost without any questions asked.
Useful for mediacenters.

=== Add AVAHI support (medium) ===

Autodiscovery of Tvheadend would be nice. This should obviously be implemented using [http://avahi.org Avahi].
This should just announce Tvheadend as some kind of service.

=== Rewrite the internal streaming pipeline (hard) ===

The internal pipeline is a bit too inflexible at the moment. The rewrite needs to address these problems:

  • Add a time-shifter.
  • Remove cumbersome locking between nodes in the pipe.
  • Prepare for adding live transcoders

This is how we want it to be:

{{{
[Input source]-[Arbitration] -+-> [Transcoder X] -> [Timeshifter] -> ... |
+-> [Transcoder Y] -> .... |
-----------------> [Timeshifter] - Multiple
+- subscribers
+-
(HTSP, RTSP, DVR, etc)
}}}

=== Switch UI to ExtJS 3.0 (hard) ===

Upgrade the user-interface to [http://extjs.com/blog/2009/05/04/ext-js-30-rc11-released/ ExtJS 3.0].
Features of particular interest would be:

  • Ext.Direct for the Comet implementation. Probably more robust than the current code.

=== Add wizards for some common tasks (hard) ===

Initially we want to add some kind of setup-wizard for the DVB subsystem. It's a bit too complicated to use at the moment.

=== Re-implement the RTSP interface (hard) ===

RTSP was thrown out of the code when Tvheadend was rewritten to be fully multi-threaded. It would be nice to get this back.

=== Realtime transcoding (hard) ===

Adding realtime transcoding of video/audio to produce low bitrate output.

=== Realtime video display in WebUI (hard/medium) ===

Multiple options exist here.

a) Application embedding (of VLC or similar) that just connects to the RTSP server.

b) Flash Video playback. Requires transcoding to h264 and AAC and a flash streaming server.

c) Use the HTMLv5 <video> tag. Requires transcoding to theora and vorbis. Does this use OGG as multiplex?
