3.0.0-beta.2

[N3XT0R]

Fixed

• FFmpeg Preview Generation & Configuration
  • Fixed a PreviewGenerationException that occurred when FFmpeg configuration parameters
    (ffmpeg_video_args) were persisted as associative arrays instead of encoded JSON.
    The configuration migration now serializes arrays before storage via Cfg::set(), preventing
    MySQL Unknown column errors and ensuring correct behavior with the json cast type.
  • Improved argument handling in PreviewService::ffmpegParams() by introducing consistent key/value
    normalization. Both indexed and associative parameter lists are now reliably converted into
    valid FFmpeg CLI arguments (e.g. -vf scale=trunc(iw/2)*2:trunc(ih/2)*2 -crf 30), ensuring
    predictable encoding behavior across environments.
  • Refined default encoding parameters (-crf, -preset, and -vf scale) to reduce preview
    file size while maintaining acceptable visual quality.
    Previous defaults produced oversized previews (up to 60–70 MB), leading to high I/O load and
    degraded server responsiveness during generation.
    Controlled compression now ensures that previews remain compact and streamable,
    even under constrained VPS conditions.
  • These optimizations also resolve a systemic performance issue where oversized previews
    could saturate PHP-FPM or Apache worker threads, blocking concurrent requests.
    By lowering per-preview CPU and disk overhead, the application now sustains
    smooth parallel generation without increasing hardware resources.
