[mythtv-users] MythTv Player 0.1a for windows

I wanted to watch live TV on my laptop with a wireless link.

I threw together two java programs. One is a "tuner" that reads my Hauppauge
PVR350 directly through /dev/video0, responds to tuning commands by issuing
ivtvctl and ivtv-tune commands, and just streams output to a client
"display" program.  Tuner is under control of xinetd so it isn't using any
resources when not running.

The other side of "tuner" is "display" which launches vlc, reads the video
stream from "tuner", and hands the video stream to vlc via stdin.  "Display"
also has a channel change window.  Display, being java, should run on just
about anything, and I think vlc versions are available for just about
anything. Vlc also has nice stuff like deinterlacing and graphics equalizer.

This has been working well over my 802.11g.  I tried 802.11b, but it's too
slow. Buffering doesn't solve speed problems; it only defers them.

I was hoping to expand the system to include more tuners (pvr350Tuner isa
Tuner isa Source), displayers (vlcDisplay isa Display isa Sink), Recorders
(source and sink for recording and playback), Transcoders (source and sink
for file format conversion), and a Manager to dynamically link up
everything.  Everything in java so it's machine independent where possible.

So far, I've only found time to write the one tuner and display.  Since this
met the immediate need, the priority has dropped :-)

>  - Both windowed and fullscreen mode
>  - Network buffering
>  - LiveTv and channel switching directly from player
>  - Independent.. So no need for external codecs
>  - Simple.. Simple, clean GUI
