  • audio dynamic range compression in php

    28 mai 2020, par monu214

    Is this possible to dynamic audio range compression in PHP. There is a lot of confusion between compression of audio, what I mean of audio compression here is described in this article.

    



    Some posts I saw here about the audio compression which only converts the audio format from wav to mp3 or other formats using FFmpeg, but what I want here is to change some audio settings like threshold, compression ratio, attack time, release time which is basic settings that can be used in audio compression.

    



    Is there any way I can do this in server-side using PHP ?

    tests/checkasm/svq1enc : Use proper range for input

    ssd_int8_vs_int16 is only called from encode_block()
    
in svq1enc.c ; it calls it in stages : At stage 0,
    
the int16_t array contains the difference of two
    
uint16_t. At each of the following stages, the
    
int16_t array is filled by subtracting an int8_t from
    
the current stage's int16_t array. The maximum stage
    
is five, so the int16_t are in the range
    
(-255 - 5 * 127)..(255 + 5 * 128).
    

    This commit modifies the checkasm test to only use
    
values from this range, fixing (undefined) integer overflow
    
in the test.

  • FFmpeg Flags for generating fixed amount of images related to video length

    27 octobre 2015, par Sutekh

    I am using this command :

    ffmpeg -i file.mp4 -vf fps=1/60 -s 274x175  thumb%d.png

    to extract 1 frame from video for every minute of it.
    What i want to learn how to do is :
    Extract a total of 10 images from video regardless of its length that are relative to distance of video.

    Example :

    1.If video length is 15 minutes (900 seconds) it will extract one image from every 90 seconds of video.
    2.If video length is 22 minutes (1320 seconds) it will extract one image from every 132 seconds of video.

    And one more thing , is it possible to use ffmpeg to set output quality of those images or limit maximum size(as in file size , not dimensions) for each image that is going to get outputted ?
