Problem solved...

The AAC encoder was set to profile "aac_main". According to https://www.ffmpeg.org/ffmpeg-codecs.html#aac the are 3 ossible values: ‘aac_low’, ‘mpeg2_aac_low’ and ‘aac_ltp’. I' ve set it to ‘aac_low’, now it works.

Thank you very much for your quick reply and your support.

Happy new year!
