ffmpeg -i test1.flv  -i test2.flv -filter_complex

This works but the audio output is from test1 only. So I try to amerge
audio and I'm thinking this... but it feels wrong and doesn't work

ffmpeg -i test1.flv  -i test2.flv -filter_complex
amerge' out.flv

[overlay @ 0xb16c5c0] Media type mismatch between the 'Parsed_overlay_3'
filter output pad 0 and the 'Parsed_amerge_4' filter input pad 0
Cannot create the link overlay:0 -> amerge:0
