 When ffmpeg is playing an SRT stream and that stream disappears (network
 issue, etc.), I believe it should exit with an error code, so that
 external scripts can respond appropriately.  Instead it returns 0.

 On the other hand, if I try to start ffmpeg with a bad SRT URL, it returns
 1 which makes sense.

 instead of a spec-compliant 7.1(wide) layout, use -strict 1 to decode
 according to the specification instead.
