  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • using ffmpeg to convert raw audio data to wav file

    10 juillet 2017, par ingeniouslyfowl

    I have a text file that contains some raw data that I generated from a wav file. I read in a signal from the wav file, and then used

    fid = open("test.raw", 'write')
    fid.write(data.tostring())

    to write the raw data to a file. Currently, I’m doing this because I want to be able to append to this file as needed without having to change header information. I’m not concatenating multiple audio files, just processing parts of a signal and I don’t want to have a potentially enormous signal in memory. When I try to use ffmpeg to convert this data using

    ffmpeg -i test.raw output.wav

    I end up getting the error : test.raw: Invalid data found when processing input. I’ve also been going through the ffmpeg docs but nothing I’ve tried seems to be working.

  • ffmpeg complex concat audio [closed]

    16 décembre 2024, par s0mbre

    I've got one video file (let's say "vid.mp4") and two audio files ("1.aac" and "2.aac") as inputs. I need to replace two parts in the original video's sound track with these two new audios, while retaining the original video track.

    


    The first cutout is at timecode from 0.44 to 1.85 sec. The second is from 15.6 sec to end of video.

    


    I'm doing it like this :

    


    ffmpeg -y -i vid.mp4 -i 1.aac -i 2.aac -filter_complex "[0:a]atrim=end=0.44[a1]; [0:a]atrim=start=1.85:end=15.6; [a1][1:a][a2][2:a]concat=n=4:v=0:a=1[a]" -map 0:v -map "[a]" -c:a aac out.mp4


    


    But the final video only contains the first audio part (a1). When trying without the video track, the same is true : only the first audio is saved :

    


    ffmpeg -y -i 1.aac -i 2.aac -filter_complex "[0:a]atrim=end=0.44[a1]; [0:a]atrim=start=1.85:end=15.6; [a1][1:a][a2][2:a]concat=n=4:v=0:a=1[a]" -map "[a]" -c:a aac out.aac


    


  • lavc/h264_parse : stop including h264dec.h

    lavc/h264_parse : stop including h264dec.h

    It is unnecessary and only files that are parts of the decoder (as
    
opposed to standalone code called by the decoder) are allowed to include
    
h264dec.h
    • [DH] libavcodec/h264_parse.c
