This string comes from an ancient and long deprecated version of libav,
I guess, could you print the full output so I can see the version?
tbr used to signal an estimate of the frame rate.
currently we print the average fps, the stream/container timebase and
the codec timebase.
the timebase and fps are expressed in fraction 1/s, so 1k means that the
time unit is 1/1000s.
