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" (...)

ffmpeg xstack filter layout limitations
7 avril 2022, par JohnQuincyKerbalI am trying to combine multiple videos using a variety of layouts. I've found an issue where a layout that is too large will result in a failed output. Even when enabling debug logs I can't see what the explicit error is. I assume I am reaching a resolution and/or size limitation when spreading the inputs out far enough. Is there some documentation outlining limitations of xstack layouts or some other documentation spelling out a different inherent ffmpeg limitation I am hitting ? Using the same exact inputs but with a smaller layout results in success.


FWIW I am using ffmpeg-python wrapper library.


Here is the verbose output I am seeing during these failures :

now i want to record via FFMPEG as smooth as possible.


therefore i tested and the following command is giving me a good result :


ffmpeg -r 60 -an -i /dev/video0 -preset ultrafast -vcodec copy test.mjpeg 


but the problem is, i get the result in slowmotion. it seems like the mjpeg file is played back in VLC in half speed. Why is this happening ?


thanks a lot,
cheers Rudi
