[FFmpeg-user] libav* : configure amerge filter

I'm trying to use FFmpeg as a library and more specifically the "amerge"
filter. But as there is very little documentation about filters and more
specifically filters with multiple inputs I don't know what to do.

Should I use a "abuffer" per input, all linked to a single "amerge" filter
? Like that :
abuffer ->

amerge -> abuffersink

abuffer ->

Or should I use a buffer with multiple channels, assigning one channel per
input file ?

Thank you very much
