The problem is that when I check the video, I get on VLC an incorrect max time 1197 hours. I know the problem is caused by the overlay (filter_complex) but don't know why. I also tried just "-filter_complex "[0:v][0:s:0]overlay[v1]" but even produces the same result.

user23175: 2 Things:
1. why do you only convert the 0 stream? you could just do -c:v libx264 (instead of -codec:v:0 libx264)
2. you could try to use the shortest statement in your overlay-statement. Like this [0:v][0:s:0]overlay=shortest[v1], 
See here for more:
https://ffmpeg.org/ffmpeg-filters.html#overlay-1
https://ffmpeg.org/ffmpeg-filters.html#framesync
You could also try reencoding your transcoded video without filters and see if you get errors or if the time is fixed after that.

<p>The problem is that when I check the video, I get on VLC an incorrect max time 1197 hours. I know the problem is caused by the overlay (filter_complex) but don't know why. I also tried just "-filter_complex "[0:v][0:s:0]overlay[v1]" but even produces the same result.</p>

1. why do you only convert the <code>0</code> stream? you could just do <code>-c:v libx264</code> (instead of <code>-codec:v:0 libx264</code>)<br>
2. you could try to use the <code>shortest</code> statement in your <code>overlay</code>-statement. Like this <code>[0:v][0:s:0]overlay=shortest[v1]</code>, </p>

<p>See here for more:<br>

<a href="https://ffmpeg.org/ffmpeg-filters.html#framesync" rel="nofollow noreferrer">https://ffmpeg.org/ffmpeg-filters.html#framesync</a></p>

<p>You could also try reencoding your transcoded video without filters and see if you get errors or if the time is fixed after that.</p>
