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" (...) -

Changer son thème graphique

ONVIF Device Manager API and Decoder
10 juillet 2023, par spidereliteI'm working on the source code of the onvif device manager software and I want to find the Api and decoder it uses.


I first separated the
odm.player
part of the code into another solution and built it separately. the separated part contains these parts from the source code (in order of execution) :

utils.linq
utils.diagnostics
utils.common
odm.player.lib
odm.player.media
live555
odm.player.net
utils.xml
utils.bootstrapping
odm.player.host



Im tring to find the decoder and Api it uses(in the above parts) to decode the media. i need to find the specific part of the program to contain some information from a decoder.


I know the source code is using
ffmpeg
andlive555
libraries but I need to find their use and API in theodm.player
part.

I checked
odm.player.host
because it is the last project and depends on previous ones, but didn't find anything.

what should i do next ? is there any official documentation of the API ? is there any important keyword related to
ffmpeg
that can I search it in the code ?

Resume transcoding a video with ffmpeg
25 novembre 2014, par Jonathan.I have a node server that uses child-process to use ffmpeg to convert a video to mp4. However if the server crashes while transcoding, then I’d like to resume transcoding the file (similar to -C with curl).
I figured I could just start transcoding the file from where it finished to a seperate file and then just concat the two. And while transcoding the file from where it finished works and the file that starts midway plays back fine, when I concat the two files with
ffmpeg -i "concat:part1.mp4|part2.mp4" -c copy ouput.mp4
Only the first part will play, and when it gets to the second part it just stays on the last frame of the first part or goes black depending on the video player. (But playing part2.mp4 itself works fine)There isn’t any error during either conversion or the concat.

FFMPEG : Cut specific parts of a video, and merge them in a single file
19 février 2017, par Jay D.I would like to cut out specific parts of a mp4 video, and merge back those parts to create a single video file. This is to make an animated preview of the video.
More specifically :
Cut out these parts of a video :- Part 1 : start time of the cut = 20% of total time ; end time of the
cut = 20% of total time + 3seconds, - Part 2 : 40% of total time ; 40%nof total time + 3 seconds
- Part 3 : 60% of total time ; 60% of total time + 3 seconds
- Part 4 : 80% of total time ; 80% of total time + 3 seconds
(The videos are more than 3 minutes long, so there should not be any overlap in the parts)
Then merge those 4 parts in a new mp4 video file. How do you do that with FFMPEG ?
Edit : so this is as far as I got for this question :
I found answers to questions on "Superuser" and "Stackexchange" for these questions on FFMPEG :
How to get video durations in seconds
Cut part from video file with start/end positions
Concatenate mp4 files
So : Get total time of video :
$ ffprobe -v error -show_entries format=duration \
-of default=noprint_wrappers=1:nokey=1 -sexagesimal inputvideo.mp4With the -sexagesimal I should get the right time format to use after.
Cut out part of video
ffmpeg -ss [start] -i in.mp4 -t [duration] -c copy /path/videopart[number].mp4
Right here I don’t know :
How to do an operation on total time (20%, 40%... then 20% +3 seconds, 40% +3 seconds..)
How to properly implement it in the code lineCreate a file videoparts.txt with the files names :
$ cat videoparts.txt
file '/path/videopart1.mp4'
file '/path/videopart2.mp4'
file '/path/videopart3.mp4'
file '/path/videopart4.mp4'Then this should merge them in a single file :
$ ffmpeg -f concat -i videoparts.txt -c copy outputvideo.mp4
- Part 1 : start time of the cut = 20% of total time ; end time of the
