Comment (by razvan):

 I think I found an inconsistency in the exit code of fmpeg when reading
 http stream:

 if I give ffmpeg a incorrect input url
 ffmpeg -i ​http://....
 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

 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.

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