Not yet.
At that time ffplay.exe worked somehow with some errors, post #57
[http @ 04933140] Invalid cookie found, no value, path or domain specified
[http @ 06820880] HTTP error 403 Forbidden= 49KB sq= 0B f=0/0
Later I discovered streamlink and beardypig wrote new filmon.py.
I missed -ldebug in livestreamer readme file back then.
I am curious what caused 403.
I did run livestreamer now for test:
C:\MISC\NEWS\HRTV>livestreamer.exe -ldebug
https://www.filmon.com/channel/bbc-news best
[cli][info] Found matching plugin filmon for URL
https://www.filmon.com/channel/bbc-news
error: No streams found on this URL:
https://www.filmon.com/channel/bbc-news
C:\MISC\NEWS\HRTV>pause
Press any key to continue . . .
Running streamlink with -ldebug there is no error now.
C:\MISC\NEWS\HRTV>streamlink.exe -ldebug
