I want to create an ElasticTranscoder Job via Lambda (NodeJS).

It works fine if I define one input (see below). But I have several source files. If I modify my coding, so that the input is an array, I'll get errors.

Can someone help me?

This works fine: 

    transcoder.createJob({
    PipelineId: '12345678-vsyssc',
    Input: {
        Key: fileName,
        FrameRate: 'auto',
        Resolution: 'auto',
        AspectRatio: 'auto',
        Interlaced: 'auto',
        Container: 'auto'
    },
    Output: {
        Key: 'Output.mp4',
        ThumbnailPattern: '',
        PresetId: '1351620000001-000030',
        Rotate: 'auto'
    }
}, function (err, data) {
    if (err) {
        console.log('Something went wrong:', err)
    } else {
        console.log('Converting is done');
    }
    callback(err, data);
});

This doesnt work: 

    transcoder.createJob({
    PipelineId: '12345678-vsyssc',
    Input: [{
        Key: 'VID-20180217-WA0002.mp4',
        FrameRate: 'auto',
        Resolution: 'auto',
        AspectRatio: 'auto',
        Interlaced: 'auto',
        Container: 'auto'
    }, {
        Key: 'VID-20180411-WA0012.mp4',
        FrameRate: 'auto',
        Resolution: 'auto',
        AspectRatio: 'auto',
        Interlaced: 'auto',
        Container: 'auto'
    },
    ],
    Output: {
        Key: 'test123445.mp4',
        ThumbnailPattern: '',
        PresetId: '1351620000001-000030',
        Rotate: 'auto'
    }
}, function (err, data) {
    if (err) {
        console.log('Something went wrong:', err)
    } else {
        console.log('Converting is done');
    }
    callback(err, data);
});

i get the Error:

  • Please show your attempt to transcode multiple files (using Inputs and Outputs) rather than one file (using Input and Output) and tell us what error you see. – jarmod Jun 08 '18 at 12:32
  • @jarmod: I adjusted my question, hope someone can tell me whats the problem – Stefan Volkmer Jun 10 '18 at 11:41
  • The documentation indicates that you should pass (plural) Inputs and Outputs for multiple files, not (singular) Input and Output. – jarmod Jun 10 '18 at 11:59
  • Sorry, i dont understand your point. I try to provide multiple objects, but then it doesn't work.how should i pass multiple objects in an other way as i tried? – Stefan Volkmer Jun 10 '18 at 14:18
  • sorry, now i got it. You are right. if i use the "Inputs"-Property instead of "Input" it works. Thank you so much! – Stefan Volkmer Jun 10 '18 at 21:02
  • Glad it's working. I have added an answer. – jarmod Jun 11 '18 at 00:33

The createJob operation uses different properties for one file vs. multiple files.

For a single input/output file:

transcoder.createJob({
    PipelineId: '12345678-vsyssc',
    Input: { <input info> },
    Output: { <output info> },
});

For multiple input/output files:

transcoder.createJob({
    PipelineId: '12345678-vsyssc',
    Inputs: [ {<input #1 info>}, {<input #2 info>} ],
    Outputs: [ {<output #1 info}, {<output #2 info} ],
});

You use Input & Output (singular) in the former but Inputs & Outputs (plural) in the latter.

At a guess, the original createJobs method only supported a single file and was later enhanced to support multiple files. To avoid breaking backward compatibility AWS added Inputs & Outputs.
