Same to me. Tested with both CLI and API versions. The issue seems to be unrelated to different properties of audio/video clips. In fact, I have tried unsatisfactorily to concatenate the example clip in the repository: ffmpeg-concat -o test.mp4 0a.mp4 0a.mp4 In the other hand, videos without audio (like 0.mp4, 1.mp4, 2.mp4) have no problem. Runingffmpeg-concat 1.2.3 and ffmpeg 4.1.6-1 on debian 10.

This temporary solution works for me: In lib/transcode-video.js, deactivate the audio option -shortest (just comment out the line).

@jamesh23 @morohit are you using audio? That option should only be included if audio is accompanying the videos.

It's been awhile since I've tested this, but I'm pretty sure that's in there so that longer audio tracks don't result in output videos where the video stream ends early and the audio stream keeps going.

Maybe something changed with FFmpeg related to this option since this library was first released?

I just published a version 1.3.3 which should resolve this issue.
