iCouldPlay Tutorials: Video, NAS and Subtitles

Start with a local video, connect NAS folders and media servers, organise films and series, then check subtitles, audio tracks and playback compatibility.

Start with the first tutorial About iCouldPlay

You provide the videos and servers. First use a familiar local file to check picture and sound, then add a remote source. This gives you a clear comparison if something fails.

Choose a tutorial for your task

Posters and categories describe media; downloads and playback access the content itself. These tutorials check them separately and do not treat a completed scan as proof that every file plays offline.

Local files & sources

Play a local video first, then add SMB, WebDAV or FTP as needed.

  1. iCouldPlay getting started: add a local video to your media library

    Import your own video from Files, check the local source, picture, sound and viewing progress, and understand the relationship between the library and original file.

Caption placement and stream time

Inspect VTT lines, HLS initialization, style blocks, ASS alignment and program-date mappings.

  1. iCouldPlay VTT line placement: distinguish line numbers, percentages and pixels

    Compare three identically worded cues while keeping source conditions, observed placement and readability separate.

  3. iCouldPlay VTT style blocks: separate STYLE, cue text and observed appearance

    Save a style block and two wording controls to inspect boundaries and rendering without promising full CSS support.

  4. iCouldPlay ASS alignment: map keypad positions to caption anchors

    Compare bottom-left, center and top-right alignment without treating an values as coordinates or screen rotation.

  5. iCouldPlay HLS dates: distinguish program timestamps, time zones and playback position

    Map two segments to absolute timestamps and relative durations without filling media dates from the device clock.

Timecode, caching and shot evidence

Separate timecode from pictures and caching from offline files, then compare zoom, rolling shutters and crosscutting.

  1. iCouldPlay timecode reading: separate drop-frame labels, picture frames and elapsed seconds

    Compare consecutive picture identities with minute-boundary labels without calling skipped timecode numbers missing footage.

  2. iCouldPlay HTTP caching: separate freshness lifetime, clip duration and offline copies

    Check a six-hundred-second freshness example without treating a cached response as a complete offline film.

  3. Compare zoom and dolly footage in iCouldPlay: enlargement is not identical perspective

    Use two planned versions with equal-width near/far cards to distinguish fixed-viewpoint magnification from camera advance.

  4. Check panning skew in iCouldPlay: separate rolling readout from real bending

    Use a straight paper reference, slower/faster pan comparison and three-row model to record skew without diagnosing a device.

  5. Read crosscut sequences in iCouldPlay: alternation does not prove simultaneity

    Use original red-A/blue-B action lines to distinguish file order, within-line order and explicit time evidence.
