    avformat/pcm: factorize and improve determining the default packet size · 9c2c0c37
    Marton Balint authored
    - Remove the 1024 cap on the number of samples, for high sample rate audio it
      was suboptimal, calculate the low neighbour power of two for the number of
      samples (audio blocks) instead.
    - Make the function work correctly also for non-pcm codecs by using the stream
      bitrate to estimate the target packet size. A previous version of this patch
      used av_get_audio_frame_duration2() the estimate the desired packet size, but
      for some codecs that returns the duration of a single audio frame regardless
      of frame_bytes.
    - Fallback to 4096/block_align*block_align if bitrate is not available.
