  • 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 stuck at 00:00:00 speed=0x for a long time at the beginning

    4 juin 2020, par lagmoellertim

    I'm currently writing a script that can remove silence from any video. I'm doing this using ffmpeg and a complex_filter script.

    



    Since most of my videos are pretty long (>1.5h), ffmpeg is called multiple times with a different complex_filter, each editing a part of the video (about 8 minutes long each) and combining those parts at the end.

    



    The input file for all these separate parts is always the original 1.5h video clip.

    



    The problem I keep getting is that for videos starting not directly at the start (first part works fine, second part starting at minute 8 takes longer, third part starting at minute 16 even longer, ... you get the point), this shows up and gets displayed for quite a long time, until it finally works with its normal speed :

    



    frame=    0 fps=0.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x

    



    Here is the ffmpeg script I use

    



    ffmpeg -i video.mp4 -vsync 1 -async 1 -safe 0 -filter_complex_script /path/to/complex_filter -y -map '[vout]' -map '[aout]' video_parts/infb4_3.mp4

    



    I also tried adding -ss 00:24:00 before or behind the -i input, but I did not notice any speed improvement.

    



    And here the complex_filter of one part of the video, starting at minute 24 and ending at minute 32 :

  • FFmpeg concatenation changes the duration and playback speed of the input videos

    24 février 2017, par Barnaby

    I have two input videos that I am concatenating using the FFmpeg concat demuxer :

    ffmpeg -f concat safe '0' -i /path/to/file.txt -c copy /path/to/output.mp4

    The file.txt contains the two file paths as follows :

    ffconcat version 1.0
    

    
file /path/to/input/file1.mp4
    

    
file /path/to/input/file2.mp4

    Unfortunately, the concatenated video has two issues :

    • The duration of the first input video is 4 seconds. In the output video, the last frame freezes for several seconds before the second input video starts.
    • The playback speed of the second input video is slowed down so that instead of being 7 seconds long, the video plays for around 14 or 15 seconds.

    I have tried specifying the duration of each video in the .txt file, as specified by the FFmpeg docs, but this doesn’t seem to make a difference to the output.

    I’m a bit of a newbie to FFmpeg, so any help is greatly appreciated !

    Edit - The properties of each input video as given by FFprobe :

  • FFMPEG changes speed when concat 2 or more different videos

    the problem is, when I run it the process speed is a lot faster then the videos length, so I got disconnected from my livestream before the live finishes.

    


    I guess it is something related to the bit rates.

    


    also I notice depends on what video is transcoding the speed floats between 0.9x and 3.7x

    Also here is a video where you can see the process

    


    https://tutorials.avideo.com/video/102/ffmpeg-changes-speed-when-concat-2-or-more-different-videos

    


    this live should have exactly 40 seconds but finishes before then that

    


    also look at this time position https://tutorials.avideo.com/video/102/ffmpeg-changes-speed-when-concat-2-or-more-different-videos?t=12

    


    the speed changes from speed=0.9 to speed=1.9

    


    speed=0.9 to speed=1.9

    


    EDITED 2 :

    


    I tried the FPS command as suggested and still the problem
