Code to reproduce

Modified example:

  app.get('/video', function (req, res) {

    const head = {
      //'Content-Length': fileSize,
      'Content-Type': 'video/mp4'
    };

    res.writeHead(200, head);


var proc = ffmpeg("./video.webm")
    // use the 'flashvideo' preset (located in /lib/presets/flashvideo.js)
    //.preset('flashvideo')
    .videoCodec("libx264")
    // setup event handlers
    .on('end', function() {
      console.log('file has been converted succesfully');
    })
    .on('error', function(err) {
      console.log('an error happened: ' + err.message);
    })
    // save to stream
.pipe(res, {end:true});



});

(note: if the problem only happens with some inputs, include a link to such an input file)

Expected results

Stream to HTTP client (h264/mp4)

Observed results

ffmpeg exit with code 1, "invalid argument" -> "pipe:1"

Checklist

• [X] I have read the FAQ
• [x] I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place)
• [X] I have included full stderr/stdout output from ffmpeg

same problem.

[mStirner]

I would make a fork and fix the bug.
But i dont want to waste my time.

It looks like the maintainer is active on github, but not in this repositroy.
When he would comment that he merge the fix, i would debug & fix the problem.
