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" (...)

Add multiple overlapping audio files to a video [duplicate]
15 juin 2024, par JTinkersEssentially, I'm trying to achieve this :



The only problem with that is - I'm using ffmpeg programatically, meaning - there won't be any predefined sounds at predefined times, instead - I have code that generates these and executes ffmpeg with the following arguments :


-f concat -r 60 -safe 0 -i {VIDEO_OUTPUT_PATH}/{fileName}.txt
{audioArgs}
-c:v libx264 -preset fast -crf 23 -vf \"scale=1080:1920,format=yuv420p\"
-c:a aac -b:a 192k
-af \"afade=t=out:st={totalSeconds - 3}:d=3\"
{mapArgs} 
-async 1 -movflags +faststart -t {totalSeconds} {outputPath}"


Presumably, if there are 3 sounds (like on the image), mapArgs will be replaced with :


-map 0 -map 1 -map 2 -map 3


and audioArgs will be replaced with :


-itsoffset 0 -i bg.mp3 -itsoffset 13 sound1.mp3 -itsoffset 37 sound2.mp3


However, it seems to be playing background music and the video only - no other sounds.

avformat/matroskaenc : Fix writing of markers
28 août 2023, par Steinar H. Gundersonavformat/matroskaenc : Fix writing of markers
When the marker writing code was merged from libav to FFmpeg
in dc62016c, it failed to take into account that the meaning of
cluster_pos had changed in bda5b662 ; in particular, the special
value for “I'm not currently working on a cluster” had changed
from 0 to -1. This makes the avio_write_marker() call never
be called. Update the if statement to fix it.Fixes : Ticket9843

well he calls javascript in a php file, in case it will upload the videos.
what I want is to get the length, resolution, file size and take a screenshot of the video randomly, so far so good, the problem is that it only works with only one upload at a time.
When sending more than one he does the procedure with ffmpeg, besides the most is not taking a screenshot of the video.
