Comment (by mkver):

 What makes you believe that max_interleave_delta "asserts" 10s content
 length by default? It just means that if it the timestamps of the already
 queued packets are more than 10s apart, then it will write something even
 if it does not have a packet for all streams.

 The bug here is not in lavf, but in ffmpeg (the cli tool), because it
 sends all the audio packets first to the muxer because it still hasn't
 encountered a subtitle packet.
