It’s raw UDP/RTP rather than RTSP, but this box should do what you need for
testing:
https://www.silicondust.com/product/hdhomerun-duo/
Hook an antenna to it, and there in tech-rich Silicon Valley you should have
lots of streams to play with. (You might find its model number easier to
search for: HDHR5-2US)
Here’s the portable command line app you’ll need to get started with:
https://info.hdhomerun.com/info/hdhomerun_config
https://github.com/Silicondust/libhdhomerun
The codecs you’ll see will vary from market to market, but if you can’t find
H.264 + AAC there where you live, implementing support for what you *do* find
should be valuable to someone. I expect there’s a lot of MPEG-2 + AC3 still
out there in the world, for example.
This then opens a question I didn’t see addressed on your new web page: what
does this program do for storage when the stream is basically never-ending, as
with live TV? I assume your program writes the chunked TS files to disk for
serving by the web server, but if you hook it up to a live TV box like the
HDHomeRun, can it fill the disk, or is there a way to set it for automatic
storage pruning short of restarting the app?
