VFR H.264 file with pic-struct, automatic FPS detection results in all timecodes = zero

That particular file will always require user intervention. Yes, it does contain picture timing SEIs, but those do not contain a clock timestamp. Furthermore the timing parameters in the SPS are as follows: num_units_in_tick = 1, time_scale = 2000000000 -- meaning that each frame is supposed to have a duration of 1 nanosecond. No wonder all timecodes are 0.

The bitstream itself simply doesn't provide useful/enough information for mkvmerge to work with.
