[FFmpeg-devel] [PATCH] fftools/cmdutils: Rename file_read to ff_file_read to avoid symbol conflict (PR #20500)

[caifan via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

PR #20500 opened by caifan
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20500
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20500.patch

The function name 'file_read' is too generic and may conflict with other functions in external code or libraries. Prefixing it with 'ff_' aligns
with FFmpeg's naming convention and improves namespace isolation.
