Cinema Video Player

Cinema Video Player is a multi-format desktop video player for Linux built
on FFmpeg/libavcodec (PyAV) and QtMultimedia audio output. A lightweight
Linux alternative to PotPlayer for multi-format video playback, subtitle
overlays, frame stepping, and PNG frame snapshots, it decodes real local
media files directly on Linux without external codec packs.

Key Features:
- Multi-Format FFmpeg Decoding: Opens MP4, MKV, WebM, AVI, MOV, TS, FLV,
MPEG, and common audio streams using bundled libavformat/libavcodec, with
synchronized stereo PCM audio output through QtMultimedia / PulseAudio.
- Subtitle Overlay & Track Selector: Automatically loads sidecar .srt and
.vtt subtitle files (or manual subtitle files via dialog) with outlined
on-video rendering, plus multi-track audio stream switching.
- Playback Controls & Frame Tools: Variable playback speed (0.25x to 4.0x),
aspect ratio presets (fit, fill, stretch, 16:9, 4:3, 21:9), single-frame
stepping, click-to-seek timeline, and one-click PNG frame snapshots saved
directly to ~/Pictures.
- Playlist & Stream Inspector: Automatically scans ~/Videos (plus folder and
multi-file pickers) and displays real container bitrate, codec profile,
resolution, frame rate, pixel format, and color metadata.
- Bilingual Header Support: Quick toggle between Vietnamese and English.
