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" (...)

Bad video quality and only 3 fps
25 juillet 2019, par ApplowPiThere are a few things wrong with the quality of the output file when I run this command.
arecord -d 0 -r 48000 -c 2 -f S16_LE -t wav -D sysdefault:CARD=tc358743 | avconv -t 0 -i pipe:0 -f v4l2 -i /dev/video0 -c:v libx264 -r 30 -acodec aac -ar 48000 -vcodec flv -strict experimental -y -f flv test.flvThe audio seems okay at the moment but, if I’m reading it correctly (at the very bottom of the output below), the fps is about 3 and the quality is at 31, which I understand is the worse. This is the output during the process.
I’m looking to get 30 fps (ideally 60 if possible).
I’m pretty new to this, any help would be great. Thanks in advance.

When linking from a static ffmpeg library, lots of undefined references
29 août 2019, par Lucas ZanellaHere’s how I’m compiling ffmpeg :
