  • 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" (...)

  • split a video with overlap between segments

    6 mai 2017, par John Pankowicz

    I need to split a video into a sequence of segments like the following : (numbers are mm:ss) 00:00 to 03:05, 03:00 to 06:05, 06:00 to 09:05, etc. In other words, each segment will have 5 seconds of overlap with the following segment. The purpose of this is for a transcription program. Each 3 minute segment will be transcribed separately. The 5 seconds of overlap will help in stitching the transcribed text segments back together.

    Do I need to extract each 3 minute and 5 second segment separately ? For example, by doing the following :

    ffmpeg -ss 00:03:00 -i in.mp4 -t 00:06:05 -vcodec copy -acodec copy -y out.mp4

    Or is there a way to do all the segments in one pass ?

  • Is it possible to split frame accurate an AAC file using FFmpeg ?

    12 mai 2019, par CAHbKA

    What I did :

    # create source material
    
ffmpeg -y -i some.file -c:a libfdk_aac -profile:a aac_he -b:a 128k -ar 44100 source.m4a
    

    
# split into two parts 
    
ffmpeg -y -ss 00:00:00 -i source.m4a -to 6 -c copy part1.m4a
    
ffmpeg -y -ss 00:00:06 -i source.m4a -c copy part2.m4a
    

    
# re-encode only the first part with the same setting as source file
    
fmpeg -y -i part1.m4a -c:a libfdk_aac -profile:a aac_he -b:a 128k -ar 44100 part1reencoded.m4a
    

    
# create file list to be concatenated
    
echo 'ffconcat version 1.0
    
file part1reencoded.m4a
    
file part2.m4a' > my.list
    

    
# finally concatenate both parts
    
ffmpeg -y -f concat -safe 0 -i my.list -c copy parts.m4a
    

    
# play the result
    
ffplay parts.m4a

    Unfortunately, the result file has noises at 00:00:06.

    Is it possible to split frame accurate an AAC file using FFmpeg ?
