Hack #84: Streaming Video Directly from TiVo
Why download massive videos and take up local hard drive space when you can stream them right from your TiVo over your home network?
Playing downloaded streams from your TiVo is just one way to use Wingert's TiVo MPlayer [Hack #83]. The whole reason he extended the original MPlayer was to enable you to stream videos right from your TiVo to your PC.
You'll need a program called vserver to pull off this hack. Download http://prdownloads.sourceforge.net/tivo-mplayer/vserver-1.2.tar.gz?download and unpack the archive. Inside, you'll find a whole slew of files. Look for a binary called vserver-ppc-s1-exec. Move and rename the file to /var/hack/bin/vserver on your TiVo. Start it up:
bash-2.02# ./vserver waiting for connections on port 8074
Launch MPlayer as in the previous hack, only this time passing it the URL
/list, replacing tivo_ip_address
with the IP address of your TiVo [Hack #51]. That magical
tivo URL handler up front (the
tivo:// bit) makes sure that MPlayer talks to the vserver on the right port with the right protocol. The
list bit, as you might imagine, requests a list of available programming. Here, I'm asking my TiVo (at IP address 192.168.0.3) for its Now Showing list:
C:\Program Files\mplayer> mplayer -quiet -cache 8192[RETURN] tivo://192.168.0.3/1662160 Playing tivo://tivo/list Listing streams in /Recording/NowShowingByTitle [Day 2: 7:00 - 8:00AM] [Day 2: 6:00 - 7:00AM] [Day 2: 5:00 - 6:00AM] [Day 2: 4:00 - 5:00AM] [9/11][(null)] [ABC World News Tonig][(null)] [The Armenians: A Sto][(null)] [Coming Attractions][(null)] [Dawson's Creek][All Good Things ... Must Come to an End] ...
Those numbers in the first column are the filesystem IDs (FSIDs) for the recorded streams, TiVo's way of indexing recorded videos. They're also used by vserver to select a show to stream:
C:\Program Files\mplayer> mplayer tivo://192.168.0.3/1662160
And up comes the final episode of 24. To stop
playback and quit MPlayer, press Control-C on the
command line. mplayer is unfortunately quite
computationally intensive, so the other flags on the command line are about
lessing the load on your PC.
-quiet supresses mplayer's output on the command line, giving your PC more
computational cycles for the video. The
-cache line asks
your PC to cache 8 MB of video data at all times while it is playing to protect
your PC against the unpredictability of networks
With vserver running, you also can extract ty streams directly from TiVo using mplayer [Hack #85]. On the command line, invoke mplayer, specifying an output file and the FSID of the stream you want to extract:
$ mplayer -dumpfile out.ty -dumpstream tivo://192.168.0.3/1692481
When you're done, don't forget to also kill the vserver process on your TiVo with a Control-C.
