  • 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.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg extra frames from video [closed]

    3 mai 2023, par catman30223

    Someone please tell me why the command does not work.

    


    ffmpeg -i /home/darryl/Desktop/video/video/video.mp4 -vf fps=30/60 /home/darryl/Desktop/video/video/img%03d.jpg

    


    I did chown the output subdirectory

    


    I have used that ffmpeg command hundreds of times without issue. I just don't get what is wrong with it. It keeps saying "no such file or directory"

    


    I also tried mkdir /mnt/temp and chown darryl:darryl /mnt/temp to extract the frames to that output subdirectory. The result was the same "no such file or directory"

    


  • FFmpeg concatenates two m4a files incorrectly

    26 février 2017, par asad

    Problem is, when i concatenate two m4a files with concat demuxer, ffmpeg produces files whose duration is incorrect. You can see that the duration of output file is very different from the duration of two input files combined. Please help me spot the issue in it. My ultimate goal is to append silent audio to the end of the audio file. For that, i generate silent audio file with ffmpeg and then try to concat it with other audio file.

    Command I used to generate audio file :

    ffmpeg -nostdin -loglevel error -y -threads 0 -filter_complex aevalsrc=0 -t 4 /home/ec2-user/videocreation/temp/silence.m4a

    Command I used for concat :

    ffmpeg -f concat -safe 0 -i temp.txt -c copy output.m4a

    I have two file paths listed in temp.txt :

    [ec2-user@ip-10-0-1-126 server]$ cat temp.txt 
    
file /home/ec2-user/videoData/DnXptC4ld8/FADING_OUT_VOLUP_Blrt_Decrypt_1ed5c4d569d8a1f23428b65217f65eaf_audio.m4a

  • "No such file or directory" sp.Popen module

    27 mars 2016, par user3481652

    I am trying to take a video and convert it in audio , for this I am using ffmpeg in python. I run the following command but it gives me " No such file or directory" for the input file. Here’s the code-

    FFMPEG_BIN = "ffmpeg"
    
import subprocess as sp
    
command = [FFMPEG_BIN, '-i', '/home/suryansh/Downloads/t.mp4']
    
pipe = sp.Popen(command, stdout = sp.PIPE)

    After executing this code I get home/suryansh/Downloads/t.mp4: No such file or directory but the file is their in the path specified.
