3 test runs with a sample file

Not having any success with my own mp4's, I tried with small samples found online (11 Sample video files | MP4 sample download), and got exactly the same errors reported here:

1 CLI

$ ffmpeg-concat -o two.mp4 sample-mp4-file.mp4 sample-mp4-file.mp4
concat error Error: ffmpeg exited with code 1: size=     199kB time=00:00:12.72 bitrate= 128.4kbits/s speed=25.4x

Error writing trailer of /tmp/de5341b43e47728da7a38df2cd40070c/scene-1.mp3: No space left on device

$ df -h

2 js

Prepare sample-mp4-file.js

const concat = require('ffmpeg-concat')

// concat 3 mp4s together using 2 500ms directionalWipe transitions
async function FFmpegConcat(){
	await concat({
		output: 'two.mp4',
		videos: [
			'sample-mp4-file.mp4',
			'sample-mp4-file.mp4'
		],
		transition: {
			name: 'directionalWipe',
			duration: 500
		}
	})
}

FFmpegConcat()

Run it:

$ node sample-mp4-file.js

I ran into the same error, is there any solution/workaround for this?

@harriott @hellno This is due to #8. Set frameFormat to png and it will consume a fraction of the space, but it will still take a long time. I am trying out https://github.com/mifi/editly since it uses streams.
