  • Using ffmpeg to obtain "raw" audio data

    10 mai 2016, par Henry W.

    I am trying to use FFmpeg, libavcodec, libavformat to extract the "raw" information from an audio file.

    I know how to read an audio file into AVFrame objects, but I don’t know how to extract the samples from the frame. The documentation does not seem to provide information for audio samples. I expect the sample to be an array of integers/floating points representing the discrete signal that represents the audio.

    How do I achieve that ?

    Update : Following the example given here, I have successfully obtained an array of samples from an audio file. However, the signal appears to be quantized, and plotting the signal (first 100ms, Sample rate : 44100, normalized with a factor of 1/2,000,000,000) gives the following : Samples
    I have also tried converting the signal bitwise to floating point, but that results in NaNs and extreme variations in the amplitude.

  • Why does ffmpeg show this "Warning : data is not aligned ! This can lead to a speed loss" ?

    4 octobre 2018, par senops

    Warning : data is not aligned ! This can lead to a speed loss
    Is it possible to fix ?

  • mediastreamvalidator "Error injecting segment data" and Can't deal with multiple sample timings per sample buffer

    14 juin 2018, par Dathan Vance Pattishall

    So using ffmpeg

    /usr/local/bin/ffmpeg -i track.m4a -vn -c:a aac -b:a 192k  -f segment -segment_list 93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.m3u8 -segment_time 120 -segment_format_options movflags=faststart  93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.%03d.m4a

    a playlist file is created where

    #EXTM3U
    
#EXT-X-VERSION:3
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-ALLOW-CACHE:YES
    
#EXT-X-TARGETDURATION:121
    
#EXTINF:120.000726,
    
93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.000.m4a
    
#EXTINF:119.883175,
    
93_jrf2niqb7n2s8pzjopkqvbbw1wmzz3foqrsa93bm.001.m4a
    
#EXT-X-ENDLIST

    Then using mediastreamvalidator I get the following output which leads me to believe there are errors which I have no idea how to fix. I am assuming that ffmpeg is jacking up the segmenting.
