  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • How to use AMD Radeon Pro W7800 to its full potential [closed]

    27 septembre 2023, par dkalna

    I have AMD Radeon Pro W7800 graphics card in my Windows 11 machine and want to convert MOV-files (which are between 12 and 15 GB big) to something more suitable (smaller). The AMD website states that supported rendering formats are following :

    


      

    • 2x Encode (H265/HEVC, 4K H264)

      • 


    • 2x Decode (H265/HEVC, 4K H264)

      • 


    • 1x Encode & Decode (AV1)

      • 


    


    For the conversion I would like to use FFmpeg. On the FFmpeg website (https://trac.ffmpeg.org/wiki/HWAccelIntro) I have seen different APIs and implementation status, but none of that make sense for me.

    


    Can someone point me in the right direction ? I would like to make files reasonable smaller (at least 50%) and would like to make the conversion fast (to use my graphics card to its full potential).

    


  • Issue with Quick Sync Video (QSV) Hardware Acceleration in FFmpeg

    6 mars 2024, par Linganiveth S.G

    It appears that FFmpeg is unable to create the necessary QSV device for decoding the H.264 video stream.

    


    I am writing to report an issue I encountered while attempting to use No device available for decoder error. hardware acceleration with FFmpeg on my system.

    


    When I run the following command to test QSV hardware acceleration :

    


    ./ffmpeg -hwaccel qsv -i input.mp4 output.ts

    


    I encounter the following error :

    


    [AVHWDeviceContext @ 0x558c6886a5c0] Error setting child device handle: -17
Device creation failed: -1313558101.
No device available for decoder: device type qsv needed for codec h264_qsv.


    


    It appears that FFmpeg is unable to create the necessary QSV device for decoding the H.264 video stream.

    


    Here are some additional details about my system :

    


    **- Operating System : Ubuntu 22.04.4 LTS

    


      

    • FFmpeg Version : 6.0

      • 


    • Processor : 12th Gen Intel(R) Core(TM) i5-12400

      • 


    • Graphics Card : Mesa Intel® UHD Graphics 730 (ADL-S GT1)**

      • 


    


    I have ensured that my system meets the requirements for QSV hardware acceleration, but I am still encountering this issue.

    


    Could anyone please assist me in resolving this issue ? Any guidance or suggestions provided would be greatly appreciated.

    


  • Ffmpeg : Improve results with h264_nvenc video codec

    7 avril 2024, par Sulli

    I was very happy to discover ffmpeg is compatible with Cuda as using a GPU speeds up my processing time by 10 at least. But I was very sad to discover codec libx264 can’t be used and h264_nvenc is of much poorer quality (my videos are visibly pixelated, to the point I actually don’t see why ffmpeg was made compatible with Cuda in the first place :) ).

    


    I did not tweak my ffmpeg commands at all when I switched from libx264 to h264_nvenc, but maybe there are some parameters I could add to get a better quality ? Even if it leads to longer processing time, I don’t mind trading a bit of that for a better quality. Or maybe another video codec I wouldn’t know about ?

    


    I usually run my scripts on Google Colab if that matters (tesla T4 graphics card, Driver Version : 535.104.05, CUDA Version : 12.2)
