For some reason, ffmpeg is skipping the audio tracks:
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:3 -> #0:1 (subrip (srt) -> mov_text (native))
Stream #0:4 -> #0:2 (subrip (srt) -> mov_text (native))
Stream #0:5 -> #0:3 (subrip (srt) -> mov_text (native))
Stream #0:6 -> #0:4 (subrip (srt) -> mov_text (native))
I cannot exactly see why, as they are detected as EAC3 audio (edited
for brevity):

I am wondering whether it's due to some feature missing - I do see a
lot of disabled stuff in your ffmpeg build:

Why would you disable the hevc parser if you intend on feeding it files
with hevc? Not sure it matters, it justs seems overly sparse to me.
