I found the problem. Just rotating one of the videos only in metadata, produce these errors. Try to encode two videos - one horizontally and another vertically oriented. Same errors - freeze frames produced by ffmpeg.
So, there is a proper way to merge two videos of different orientation without rencoding two times with ffmpeg?

Also, there is the problem how can you know if one of these videos is "rotated" only in metadata beforehand?
