Comment (by milahu):
a workaround is to get the actual duration of the audio track
and limit the transcoding process with `-to $src_adur`
{{{
src_path="video.mkv"
src_aid=0 # audio track id
# get the actual duration of the audio track
# https://stackoverflow.com/a/74970367/10440128
src_adur=$(
ffmpeg -i "$src_path" -c copy -map 0:a:$src_aid -f null - 2>&1 |
awk -F= 'BEGIN{RS=" "}/^time=/{t=$2}END{print t}'
)
# transcode audio to aac
# limit transcoding to $src_adur
# workaround for: ffmpeg hangs at "File ended prematurely"
af="..."
args="-af $af -resampler soxr -ar 48k"
ffmpeg -i "$src_path" -map "0:a:$src_aid" -to $src_adur $args -f wav - |
qaac -s --no-delay -o dst.m4a -
