  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Submit enhancements and plugins

    13 avril 2011

    If you have developed a new extension to add one or more useful features to MediaSPIP, let us know and its integration into the core MedisSPIP functionality will be considered.
    You can use the development discussion list to request for help with creating a plugin. As MediaSPIP is based on SPIP - or you can use the SPIP discussion list SPIP-Zone.

  • 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

    


  • 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.
