I got teased by seeing my hdhomerun in the upnp section in vlc on my imac g4 and it barely working. So I wasted an afternoon. I'm sure there is an easier way. But I got it working well. I just wanted to watch jeopardy while making dinner.
This is g4 specific because of the altvec engine being able to hardware decode mp4 with coreplayer.
You are going to need:
A G4 mac: 1ghz MDD and imac tested running Sorbet leopard with coreplayer 1.3.6.
Any modern computer with the latest vlc. (Using a 2018 mini)
On your bridge
Go to http://hdhomerun.local/lineup.html
Right click the channel you want to broadcast and click copy
On VLC go to open network and paste that address
Click stream then hit settings and put in the settings listed in picture 1
Go to settings click show all and under stream output/Sout stream/transcode and click deinterlace and set the output size. 854/720/640 (whatever looks right by 480. Then click open to start the stream.
Go to network and look up your local address http://192.168.1.xxx
This will output your stream across your local network.
On your G4:
Open coreplayer and click open url
Paste your modern computers IP with the port number chosen in pic 1 e.g.http://192.168.1.xxx:8080
Click enter and enjoy! You can now watch hdtv in the same quality of a divx Stargate sg1 episode you downloaded from the bay 20 years ago.
On your modern computer you can just open network stream and it will have saved everything so just change the channel number. You can do that for every channel in your lineup and it will save it.
I've played a lot with this but this is the happy spot I've found. This also works with only an airport extreme if it has a good signal.
This also works with VLC but you will max your CPU and it will drop like mad. Coreplayer uses about 60% cpu on the imac.
You can also turn down the resolution in pic 2 to a 320 or 240 aspect ratio and/or try it with a slower g4 or even a g3 with mpeg1 instead of mp4.
Please give me feedback if I could be setting it up better.
