    aacenc : add support for encoding files using Long Term Prediction

    Long Term Prediction allows for prediction of spectral coefficients
    
via the previously decoded time-dependent samples. This feature
    
works well with harmonic content 2 or more frames long, like speech,
    
human or non-human, piano music or any constant tones at very low
    
bitrates.
    

    It should be noted that the current coder is highly efficient and
    
the rate control system is unable to encode files at extremely
    
low bitrates (less than 14kbps seems to be impossible) so this
    
extension isn’t capable of optimum operation. Dramatic difference
    
is observable with some types of audio and speech but for the most
    
part the audiable differences are subtle. The spectrum looks better
    
however so the encoder is able to harvest the additional bits that
    
this feature provies, should the user choose to enable it. So
    
it’s best to enable this feature only if encoding at the absolutely
    
lowest bitrate that the encoder is capable of.

  • ffmpeg probesize and analyzeduration flags

    7 mai 2014, par Xerphiel

    Could someone explain to me in simple terms what these flags/options do ?

    Running "ffmpeg -h full | grep probesize/analyzeduration" yields the following documentation :

    -probesize         <int>        .D.... set probing size (from 32 to INT_MAX) (default 5e+06)
    
-analyzeduration   <int>        .D.... specify how many microseconds are analyzed to probe the input (from 0 to INT_MAX) (default 5e+06)
    
</int></int>

    This is beyond my understanding, so am hoping for a simpler explanation.

    All the discussions on this subject I’ve found via googling do not describe the basic function of the options.

    Any help is appreciated.

    Thank you.
