Frame number. Pre-encoding: number of frames sent to the encoder so far.
Post-encoding: number of packets received from the encoder so far.
@item ni
Input frame number. Index of the input frame (i.e. output by a decoder) that
corresponds to this output frame or packet. -1 if unavailable.
@item tb
Encoder timebase, as a rational number @var{num/den}. Note that this may be
different from the timebase used by the muxer.
@item tbi
Timebase for @var{ptsi}, as a rational number @var{num/den}. Available when
@var{ptsi} is available, @var{0/1} otherwise.
@item pts
Presentation timestamp of the frame or packet, as an integer. Should be
multiplied by the timebase to compute presentation time.
@item ptsi
Presentation timestamp of the input frame (see @var{ni}), as an integer. Should
be multiplied by @var{tbi} to compute presentation time. Printed as
(2^63 - 1 = 9223372036854775807) when not available.
@item t
Presentation time of the frame or packet, as a decimal number. Equal to
@var{pts} multiplied by @var{tb}.
@item ti
Presentation time of the input frame (see @var{ni}), as a decimal number. Equal
to @var{ptsi} multiplied by @var{tbi}. Printed as inf when not available.
@item dts
Decoding timestamp of the packet, as an integer. Should be multiplied by the
timebase to compute presentation time. Post-encoding only.
