Thanks for the example but it is lacking if you are going for precision. The console output has far more useful information, you should post that also.

> output.mp4 first 10 seconds is not visible, but the audio yes. After about 10 seconds of output.mp4, both are present. It's not dependent of output.mp4 lenght or duration.
I’m thinking it would be dependent of the start point you choose, with there being a certain point every ~20 seconds that you can seek to in the video.

You can try putting the -ss argument before the input to see if it provides the behavior you are looking for.
