Comment (by razvan):
****
if I give ffmpeg a incorrect input url
ffmpeg -i http://.../livestream_a/playlist.m3u8 <<<< incorrect
ffmpeg -i http://.../livestream_ao/playlist.m3u8 <<< this is the
correct one
which is not found on the streaming server then ffmpeg report
"HTTP error 404 Not Found"
and exit code is 1
I think this is correct as ffmpeg completes with an error,
so exit code !=0
command and output

if input url is correct and it starts reading it and so on (save the
stream for example),
and after a while, the server return again "HTTP error 404 Not Found" for
some chunk
then ffmpeg exit with code 0.
This I cannot reproduce anytime as it depends on the streaming server to
have a glitch of some sort

- after some time of running fine with output as above
the streaming server seems to have a glitch of some sort

ffmpeg exit code=0
I think this is incorrect because ffmpeg ended with an error,
so it should return something other then 0.
Thanks
