  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • ffmpeg split avi into frames with known frame rate

    31 mai 2016, par Myx

    I posted this as comments under this related thread. However, they seem to have gone unnoticed =(

    I’ve used

    ffmpeg -i myfile.avi -f image2 image-%05d.bmp

    to split myfile.avi into frames stored as .bmp files. It seemed to work except not quite. When recording my video, I recorded at a rate of 1000fps and the video turned out to be 2min29sec long. If my math is correct, that should amount to a total of 149,000 frames for the entire video. However, when I ran

    ffmpeg -i myfile.avi -f image2 image-%05d.bmp

    I only obtained 4472 files. How can I get the original 149k frames ?

    I also tried to convert the frame rate of my original AVI to 1000fps by doing

    ffmpeg -i myfile.avi -r 1000 otherfile.avi

    but this didn’t seem to fix my concern.

    hwcontext_vulkan : minimize queue allocation on NVIDIA

    On NVIDIA, there's a global maximum limit of approximately 112 queues,
    
which means it takes ONLY 7 total programs using the maximum amount of
    
queues to cause the driver to error out/*segfault* during initialization.
    

    Also, each queue takes about 30ms to allocate, which quickly adds up.
    

    This reduces the queues allocate to the minimum that we would be happy
    
with. Its not worth limiting decode/encode queues as they're generally
    
not a lot, and do help.
