"""
This script is meant to display stats written by mpv --dump-stats=filename.
In general, each line in that file is an event of the form:

    <timestamp in microseconds> <text> '#' <comment>

e.g.:

    10474959 start flip #cplayer

<text> is what MP_STATS(log, "...") writes. The rest is added by msg.c.

Currently, the following event types are supported:

    'signal' <name>             singular event
    'start' <name>              start of the named event
    'end' <name>                end of the named event
    'value' <float> <name>      a normal value (as opposed to event)
    'event-timed' <ts> <name>   singular event at the given timestamp
    'value-timed' <ts> <float> <name>       a value for an event at the given timestamp
    'range-timed' <ts1> <ts2> <name>        like start/end, but explicit times
    <name>                      singular event (same as 'signal')
