Comment (by tmm1):

 Here's what I see after upgrading to macOS 10.13

 {{{
 $ h264_analyze out-vt.h264 | grep -A3 timing_info | head -4
  timing_info_present_flag : 0
    num_units_in_tick : 0
    time_scale : 0
    fixed_frame_rate_flag : 0
 }}}

 {{{
 $ ffmpeg -i out-vt.h264
 Stream #0:0: Video: h264 (High), yuv420p(progressive), 1920x1080 [SAR 1:1
 DAR 16:9], Closed Captions, 25 fps, 25 tbr, 1200k tbn, 50 tbc
 }}}

 The fixed fps is no longer part of the SPS. However ffmpeg still
 identifies the file as 25fps for some reason.
