[FFmpeg-user] Video concat problem

[iburman at compuscience.com]

I have two videos that I want to concatenate:

 

Video 1 - very short one with a silent audio track (2 seconds)

 

Video 2 - About 2 minutes. The audio starts around 10 seconds from start

 

The final concatenation is strange:

 

Starts with video 1 as expected (2 seconds)

Next, a blank for about 10 seconds

After that, video 2 starts simultaneously with the audio. In other words,
the video stream of video 2    was moved to start together with the audio,
instead of showing for 10 seconds with silence.

 

How can I fix this?

 

I am attaching the stream info for each file in case this helps.

 

Thanks
