 So this bug is simple to explain. At our business ffmpeg runs a transcoe
 job and writes to a networked filesystem. This generally works great.
 In this instance the network glitshed and the NAS was unavailable, but
 ffmpeg still exited with error code 0.

 This is a bug. I understand that ffmpeg should not exit in many situations
 due to errors, seeing as one of the jobs so well is fix bad input data,
 which generates loads of error situations.

 So using -xerror is not an option here.

 stdout from run attached, together with cmdline. The error that should
 have caused an exit, however is here:

 As it turns out around 600 files in out movie archive generated this year
 are corrupt, without us knowing.
