[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Sat Mar  9 19:53:11 2024 +0100| [639208cc6adae159008e089f7d82f132720f7fc9] | committer: Anton Khirnov

fftools/ffmpeg_filter: don't forward EOF in close_output()

The caller does not need or expect it, and it can lead to terminating
filtering prematurely in case there is more than one output.
