Opening your first video

From the command line

cargo run --release -p trango -- <path/to/video> [path/to/subs.srt] [path/to/subs.translation.srt]

All three arguments are optional:

• With no arguments, TrangoPlayer opens an empty window — use the top bar's "Open video…" button to pick a file.
• With just a video path, TrangoPlayer looks for a subtitle file with the same name next to it (video.mp4 → video.srt) and links it automatically if found.
• The second argument links a specific subtitle file explicitly.
• The third argument links a second subtitle file as a translation track, shown alongside the original (see Subtitles).

From inside the app

Click "Open video…" in the top bar. This opens an in-app file browser (not your operating system's native file picker) starting in the folder of the last video you opened. Navigate into subfolders with the listed folder rows, or go up with the "‥ Up" row, then select a video and click "Open".

Opening a video this way also tries to auto-match a same-name subtitle file, exactly like the command-line path above.

What happens next

TrangoPlayer always opens paused — nothing plays automatically, no matter how you opened the video or whether a subtitle was found. Press Space to start playback. See Playback modes for what Space, and the rest of the keyboard shortcuts, do in each mode.

If no subtitle file was found, the video still plays fine in Normal mode; Sentence-by-sentence mode needs a subtitle to know where the sentence boundaries are. You can link one — or generate one automatically — from the "Subtitles…" button, covered in Subtitles.
