    avconv: Set audio filter time base to the sample rate · 715129cd
    Martin Storsjö authored
    If the output frame size is smaller than the input sample rate,
    and the input stream time base corresponds exactly to the input
    frame size (getting input packet timestamps like 0, 1, 2, 3, 4 etc),
    the output timestamps from the filter will be like
    0, 1, 2, 3, 4, 4, 5 ..., leadning to non-monotone timestamps later.
    A concrete example is input mp3 data having frame sizes of 1152
    samples, transcoded to aac with 1024 sample frames.
    By setting the audio filter time base to the sample rate, we will
    get sensible timestamps for all output packets, regardless of
    the ratio between the input and output frame sizes.
