Comment (by RavenWorks):

 Well this is also fascinating:


 {{{
 ffmpeg -y -f lavfi -i "anullsrc=mono:d=50" -i .\no_audio.mp4 -shortest
 silent_audio.mp4
 }}}
 ... consistently reproduces the bug.

 {{{
 ffmpeg -y -i .\25sec.wav -f lavfi -i "testsrc2=r=60:d=0.15" -shortest
 silent_audio.mp4
 }}}
 ... consistently reproduces the bug.


 but,
 {{{
 ffmpeg -y -f lavfi -i "anullsrc=mono:d=50" -f lavfi -i
 "testsrc2=r=60:d=0.15" -shortest silent_audio.mp4
 }}}
 ... USUALLY does NOT reproduce the bug! (Though SOMETIMES it still does!)


 I think `-shortest_buf_duration 30` is still the bigger breakthrough, but
 these are both interesting bits of information...
