Could not write header for output file #0 (incorrect codec parameters ?): Error number -22 occurred
Problem there is the mismatch between "5.1(side)" and "5.1" does anyone know to tell ffmpeg to use the same layout that the input uses?

btw. for those curious the 'filter_complex'-part encodes 138ms of silence and appends them before the original stream, which is used to compensate a 138ms delay in the input stream.

Ps.: no, I do not want/can't to use another tool.
