Ps.: I frist used the same call without '-fflags +genpts', but added
'-fflags +genpts' after reading: https://trac.ffmpeg.org/ticket/1552 and
https://trac.ffmpeg.org/ticket/1553. Created a new debug entry since 1552
uses avi as input and 1553 uses mpeg2 video and not H264.
Stumpled over this after reading https://github.com/jb-alvarado/media-
autobuild_suite/issues/8, seems like this problem does not exist in the
stable build.
