I have recently built a new system, installing 30.0 and importing an old
database.
I want to use Dan Freys MythTV Player, so created the 'streaming' storage
group within the database, which did not previously exist.
Streaming to MythTV Player is not working and neither is using the Play in
Browser option of MythTV WebFrontend.
mythbackend.log shows the following:
Apr 1 22:48:42 ford mythbackend: mythbackend[6911]: W HTTPLiveStream
HLS/httplivestream.cpp:85 (run) HLS(): Command '/usr/bin/mythtranscode
--hls --hlsstreamid 21 --verbose general --loglevel info --quiet --syslog
local7' returned 139
Running the same command manually, but with more logging shows:
$ /usr/bin/mythtranscode --hls --hlsstreamid 21 --verbose record --loglevel

And a check of the streaming storage group appears to indicate that all is
OK:
