  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • how to use command line to stitch two wav together using ffmpeg in linux ?

    10 octobre 2018, par spartaslave

    I have installed ffmpeg on debian and I tried the two command lines.
    There are two files under the same directory, they are first.wav and second.wav
    The first method is to create a txt file, inside a.txt, they are

    file 'first.wav'
    
file 'second.wav'

    I have run

    ffmpeg -f concat -i a.txt -c copy final.wav

    then I run it, it could work fine.
    But I want to try another method,
    which is

    ffmpeg -i "concat:first.wav|second.wav" -c copy final2.wav

    there is not error with the sdcond command line, but it only capture the first file and the length of final2.wav is almost same as first.wav. File second.wav is not stitched at all.
    As I am using golang to execute the command line, I want to use

    cmd := exec.Command("ffmpeg",args)

    to stitch the medias together, I can read all the media files into an array, but this API cannot work for the array, so I want to stitch the files together to

    "concat:file1.wav|file2.wav|file3.wav|......"

    in this case it could be easy to stitch the files together and I do not need to loop the cmd.
    like

    cmd = exec.Command("ffmpeg","-i","concat:first.wav|second.wav|third.wav|......","-c","copy","final2.wav")

    I do not want to create any extra files like a.txt file as I need to delete it later and this may also touch the permission.
    So is there any possible solution for the second command line ?

    avfilter/vf_psnr : Prevent integer overflow.

    The 32-bit integer accumulator in MSE computation can overflow for 8-bit frame data.
    
(e.g., for 1080p white frame compared to a black frame can give sum of 255*255*1080*1920 > 2^32).
