Prevent ffmpeg from hanging extracting subtitles (#17297)

2026-07-17T21:23:57Z

* Prevent ffmpeg from hanging extracting subtitles Add `RunSubtitleExtractionProcess` to unify the external _ffmpeg_ process handling and error management. Add a `-nostdin` flag that prevents _ffmpeg_ from reading from _stdin_ and blocking on an inherited stdin handle (e.g. when Jellyfin runs as a service under NSSM), which otherwise hangs subtitle extraction forever when _ffmpeg_ blocks on any keyboard-interaction read until the timeout (30 minutes). Close the redirected _stdin_ to ensure immediage EOF. Drain the _stderr_ to a string and log it, to ensure we don't block the _ffmpeg_ process on errors that exceed the pipe length. Pass `-y` to _ffmpeg_ to ensure it overwrites any existing output file without prompting for confirmation. * Address review comments Make sure we always drain stderr. Make sure the timeout also honors the cancellationToken. Make sure when we get cancelled we don't log it as a ffmpeg error.

Fix potential garbled text in FFmpeg logs on Windows

Explicitly set StandardErrorEncoding and StandardOutputEncoding to Encoding.UTF8 when invoking the FFmpeg subprocess. This prevents log encoding issues and character corruption on Windows environments that default to non-UTF8 ANSI code pages. This fixes garbled metadata and font names in the FFmpeg logs.

Use InvariantCulture when parsing machine-generated dates

2026-07-04T21:55:31Z

DateTime.TryParse without an IFormatProvider falls back to the current thread culture, so the same string can parse differently (or fail) depending on the server's locale. None of these call sites deal with user-entered text - they parse dates that come from filenames, an HTTP header, ffprobe metadata and values the app itself wrote to the auth database - so InvariantCulture is the correct provider everywhere here. Fixes the S6580 / CA1305 warnings on these call sites. Co-Authored-By: Claude Opus 4.8
