Comment (by mldwrp):

 Hi, I've asked the author of that commit (Mark Thompson) a question on
 GitHub, but got no reply for two years.
 I hope I'll have better luck here — as I'm updating my higher level
 library at this moment — anyone is welcome to help.

 @fhvwy Hello Mark,
 Thank you for your work.

 It so happens that this change has broken my
 https://github.com/costa/ffmprb as it relies on an ability to distinguish
 between pipe (IO) errors and other crashes.
 Now, this change doesn't seem to me all that necessary, I usually follow
 the "fail fast" philosophy (report and expect the upper layer to handle
 failures) — it might benefit the end-user, but distinction between I/O
 failures and others is apparently important for integration.
 And I believe ffmpeg is mostly used in integrations where running few
 processes in parallel is no problem (so each stream error can be reported
 separately).

 There is, however, a better way than reverting this change, and it's just
 to report all I/O errors with a special exit code.
 Thank you again.
