ti.ios.trim Module

Description

This module extends the Appcelerator Titanium Mobile framework and allows trimming and compressing videos on iOS. This is currently not possible using Titanium's VideoPlayer:

[#TIMOB-1816] iOS: Phone > Record Video, edit/trimming is not shown in playback - Appcelerator JIRA [#TIMOB-4200] iOS - Edit mode on record video returns entire video - Appcelerator JIRA

Getting the module

Find the newest version in the dist folder.

Referencing the module

Simply add the following lines to your tiapp.xml file:

<modules>
    <module platform="iphone" version="0.2">ti.ios.trim</module>
</modules>

Accessing the module

To access this module from JavaScript, you would do the following:

var trimmer = require('ti.ios.trim');

The trimmer variable is a reference to the Module object. a

Reference

trimVideo({Object} options)

options can have the following keys:

• input
  • the path to video file to be trimmed
  • this has to be either an absolute file path (via file.resolve()) or a path to an object inside the asset library (e.g. using the TiAssetsLibrary Module)
• quality (optional)
  • the quality of the output video (1 = low, 2 = medium, 3 = high)
  • as an orientation: the example .mp4 file has a size of 15.3 MB and the output file (no trimming, only compression) sizes are the following: 1.12 MB (low), 6.12 MB (medium), 15.26 (high)
• startTime (optional, default: 0)
  • beginning of the trimmed movie (in seconds)
• endTime (optional, default: duration of the video file)
  • end of the trimmed movie (in seconds)
• success
  • callback to be invoked after successful trimming
  • the callback is passed an object that has the following properties:
    • thumbnail: the thumbnail of the video as an image blob
    • videoURL: the path to the trimmed video file
• error
  • callback to be invoked in case of an error

var inputFile = Ti.Filesystem.getFile('path/to/videoFile');
trimmer.trimVideo({
    input: inputFile.resolve(),
    quality: 1,
    startTime: 0,
    endTime: 10,
    success: function(e) {
        Ti.API.info('SUCCESS:');
        Ti.API.info('path to trimmed file: '+ e.videoURL);
    },
    error: function(e) {
        Ti.API.error('ERROR:');
        Ti.API.info(JSON.stringify(e));
    }
});

Changelog

• 0.3:
  • adds the thumbnail of the trimmed video to the success callback
• 0.2:
  • adds an optional quality parameter to compress videos
  • adds support for video files inside the asset library
  • makes startTime and endTime optional
• 0.1: Initial version
