  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP 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" (...)

  • Storing high quality video stream (from IP Action Camera) continuously to a Storage Device and issues around Write-Speed bottlenecks

    21 mai 2017, par Aldo

    I am looking to get an Action Camera (Eken H8R, or a GoPro) for a project. Let me explain the scenario I have :

    I will obtain a live stream from the camera on to a Raspberry Pi (over WiFi) as shown here. Next, I want to continuously segment this live stream into 10-15 minute video clips and store them in an external Hard Drive (which is connected to the RPi). I am considering this thread, and the avconvcommand mentioned in the answer by Alexander.

    Now, my concern is write-speed limitations. The video stream would probably have a high bitrate, and might be 4k30fps, in which case file sizes would be huge. Would write speed to disk be a bottleneck ? If so, how will the Pi maintain a buffer to achieve this ? Could I run out of space as the memory stick on the Pi would only be around 8 gigs ? If so, what’s a better alternative ? Please correct me if I’m wrong on these as I’m only a beginner.

  • ffmpeg low speed on AMD encoder

    13 octobre 2022, par Peter Czask

    I'm encoding some videos with ffmpeg, if I use only CPU the speed it's about 1x, so as I have an AMD RX580 I tried with amd encoding, but only increased the speed to 1.5x. Is this ok ? Should it go faster ?

    


    My command is :

    


    ffmpeg -i 5.mp4 -c:v h264_amf -lavfi "[0:v]scale=1920:1080,boxblur=luma_radius=min(h\,w)/8:luma_power=1:chroma_radius=min(cw\,ch)/8:chroma_power=1[bg];[0:v]scale=-1:1080[ov];[bg][ov]overlay=(W-w)/2:(H-h)/2,crop=w=1920:h=1080" output.mp4


    


    Can I do anything to increase the speed ?

    


    Thanks

    


  • Ffmpeg scroll speed not changing

    15 novembre 2022, par J C

    I am trying to change scroll speed of a video.
ffmpeg -loop 1 -i 'document-%02d.jpg' -vf "scroll=vertical=0.02,crop=iw:600:0:0,format=yuv420p" -t 20 output.mp4
And
ffmpeg -loop 1 -i 'document-%02d.jpg' -vf "scroll=vertical=0.51,crop=iw:600:0:0,format=yuv420p" -t 20 output.mp4
Gives same result.

    


    It works for single image. But when i add %02d for multiple it not works.
