  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Compression rate (final size) ffmpeg with h263 as codec, can be improved ?

    29 août 2013, par voskyc

    With the following data :

    Sample 1 :
    vcodec : H263
    Duration : 4seconds
    Resolution:1288/720
    FR : 30fps/s
    datarate : 195.135 kB/s
    MP3 : 44HZ, 16bits

    Size file : 5.84MB.

    Sample 2 :
    vcodec : H263
    Duration : 4seconds
    Resolution:640/480
    FR : 30fps/s
    datarate : 195.135 kB/s
    MP3 : 44HZ, 16bits

    Size file = 3.34MB.

    Both in flv container.

    Aren't those sizes a little bit high for 4 second video ?

    I believe we are doing some kind of error or missing an optimization.
    Should we decrease the datarate ?
    Maybe we are missing some option for h263 encoding with FFMPEG ?.

    Thanks a lot in advance for your suggestions.

    Note : no, we "can not" use h264. :-)

  • MoviePy : Concatenating video clips causes weird glitches in final video

    16 mai 2022, par JohnSmithy1266

    Is there a way to successfully always patch up any clips together in such a way that prevents weird glitches ? I put together a .mp4 from smaller .mp4 files and I got a final video with weird glitches. I am running Python 3.6.1 on Windows 10 through Sublime Text 3. I used MoviePy to do the concatenation.

    



    The code :

    



    from moviepy.editor import VideoFileClip, concatenate_videoclips
import os.path

path = "C:/Users/blah/videos/out/"

cliparray = []

for filename in os.listdir(path):
    cliparray.append(VideoFileClip(path + filename))

final_clip = concatenate_videoclips(cliparray)

final_clip.write_videofile(path + "concatenatedvideo.mp4", codec = "libx264")


    



    The weird glitches :

    



      

    1. One of the clips turns into a 3x3 grid of smaller clips.

      2. 


    2. Another has the audio not lined up with the video

      3. 


    3. Another is sped up faster than what was normal.

      4.
