Media Filter Transcoder

A per-stream Direct Copy or Convert video and audio transcoder with an integrated Filter Studio for Linux.
A lightweight Linux alternative to XMedia Recode for stream-level remuxing, selective re-encoding, and audio/video filtering.

Key features powered by bundled FFmpeg:
- Independent per-stream Copy-or-Convert modes: choose Direct Stream Copy (-c copy) or re-encode Video (H.264/AVC, H.265/HEVC, VP9, MPEG-4) and Audio (AAC, Opus, MP3, FLAC, PCM 16-bit) across MKV, MP4, WebM, MOV, and AVI containers.
- Video Filter Studio with 90/180/270 rotation, horizontal/vertical flip, aspect-ratio crop/pad, Color Equalizer (brightness, contrast, saturation, gamma), and side-by-side frame preview.
- Audio Filter Chain supporting dB volume gain, dynamic audio normalization (dynaudnorm), and stereo/mono channel remapping.
- Built-in Audio Loudness Analyzer (FFmpeg volumedetect RMS/Peak dB) and one-click lossless container remuxer.
