What would you like to do?
Merge multi webm (audio) with FFMPEG
ffmpeg \
-i input1.webm \
-i \
-filter_complex "[0:a][1:a]concat=n=2:v=0:a=1[aout]" -map "[aout]" \
-c:a libvorbis -strict experimental \
# Notes: [0:a][1:a] and concat=n=2 is depending on number of inputs (-i)
# you can use libvorbis or libopus as codec
