Comment (by razvan):

 ****
 if I give ffmpeg a incorrect input url
         ffmpeg -i ‚Äčhttp://.../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
