Creating farms of unique websites
13 avril 2011, parMediaSPIP 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" (...) -
Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

ffmpeg loop through directory tree, output to identical tree in different root, only process files once
22 juin 2020, par John MI would like ffmpeg to continuously loop through one directory structure looking for *.webm files and then convert them to mp4 when found, outputting them to an identical sub directory structure under a different path. Sub-directories/files are added to the tree automatically. I can do this manually, but my scripted attempts failed, I was using an ionotify event script to look for the new directories and re-running the conversion script, but it will not run continuously. I also do not want to process a file again once it has been converted.


I was using this invoked with each inotify :


find /opt/media/ -name "t_str_*.webm" -exec bash -c \
'ffmpeg -loglevel panic -acodec libopus -i $0 -strict experimental -movflags faststart ${0/webm/mp4}' {} \;


I have the following directory structure, the subdirectories are alphanumeric.


Source :


parent1
 - AAAAAA
 - file1.webm
 - BBBBBB
 - file2.webm
 - CCCCCC
 - file3.webm
 - ZZZZZZ
 - file4.webm


Destination :


parent2
 - AAAAAA
 - file1.mp4
 - BBBBBB
 - file2.mp4
 - CCCCCC
 - file3.mp4
 - ZZZZZZ
 - file4.mp4


Any suggestions ?

remove space from the path of the videos to be converted by ffmpeg on rails 3
8 janvier 2014, par Mikei am using ffmpeg to convert videos uploaded by the user on rails 3 windows platform.Now when i use
ffmpeg -i C:\three.wmv -vcodec h264 C:\threeeeee.mp4i get the converted video ready to play,but when i use the default path from paperclip such ashas_attached_file :source,
:max_size => 300.megabytes,
:url => "/assets/uploads/:id/:style/:basename.:extension",
:path => ":rails_root/public/assets/uploads/:id/:style/:basename.:extension",
:processors => [:ffmpeg]i get error as
No such file or directorybecause the project is in the folder asc:new projects/new/app..and so on.its because of the space between the folder name new project...
so how to avoid it.i know its a kind of weird behavior but i need the reason because changing just the folder name doesnt make any sense to me.my video.rb
has_attached_file :source,
:max_size => 300.megabytes,
:url => "/assets/uploads/:id/:style/:basename.:extension",
:path => ":rails_root/public/assets/uploads/:id/:style/:basename.:extension",
:processors => [:ffmpeg]
after_create :convert_in_flv, :set_new_filename
def convert_in_flv
system("ffmpeg -i #{Rails.root}/public/assets/uploads/#{self.id}/original/#{self.source_file_name} -vcodec h264 #{Rails.root}/public/assets/uploads/#{self.id}/original/#{self.id}.mp4")
###system("ffmpeg -i #{source.path} -vcodec libx264 -vpre ipod640 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s 480x320 #{flv}")
end
##ffmpeg -i C:\three.wmv -vcodec h264 C:\threeeeee.mp4....this works
def set_new_filename
update_attribute(:source_file_name, "#{id}.flv")

ffmpeg error when using non root user
29 août 2014, par mkernI have installed ffmpeg and it works perfect if you are root or using sudo but it errors out when trying to use it as a non-root user. I have performed the same install on a test VPS and it installs without issue so it appears to be isolated to this cPanel server. I haven’t been able to identify why.
