Move the ffmpeg -ss (seek/offset) parameter before -i in all transcoding commands so ffmpeg uses input seeking instead of output seeking. Per the ffmpeg docs, placing -ss before -i seeks at the demuxer level by keyframe (very fast), and since FFmpeg 2.1 it is also frame-accurate when transcoding. The previous placement after -i caused ffmpeg to decode and discard all audio up to the seek point, which was unnecessarily slow — especially problematic for lengthy files (4+ hours). Both code paths are updated: buildDynamicArgs (for default formats) and createFFmpegCommand (for custom templates without %t). A database migration updates existing default commands in the transcoding table.
