  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • FFMPEG : how to create a "title slide" for 3 seconds before a video [closed]

    15 mars 2024, par ashay

    I'm trying to make a lecture video to put online. I have the video itself, and I have a title slide that I'd like to play for 3 seconds before the main video.

    &#xA;

    I tried using ffmpeg to (1) create a 3 second long video from the title slide and (2) concat the two videos together.

    &#xA;

    I'm having issues concatenating the videos together — when I do so, the resulting video is much longer than it should be. When I look online, others have similar problems — and this seems to occur when the parameters of the two videos do not match perfectly.

    &#xA;

    I'd prefer to do this without re-encoding the main video — and it seems this should be possible because I should be able to control what parameters are set for the "lecture slide video".

    &#xA;

    Here are the commands I've run.&#xA;The main video has framerate 25, resolution 1920x1080, and an audio stream at #0:0 and a video stream at #0:1 (according to ffmpeg -i [video].

    &#xA;

    To create the video of the title slide, I ran ffmpeg -framerate 25 -i lec01_title.png -t 3 -c:v libx264 -x265-params lossless=1 -pix_fmt yuvj420p -vf scale=1920:1080 lec01_title.mp4 -f lavfi -i anullsrc -c:a aac -shortest.&#xA;Then to reorder the streams to match the main video, I ran ffmpeg -i lec01_title.mp4 -map 0:a -map 0:v -c:v copy -c:a copy lec01_title_matched.mp4.

    &#xA;

    Then to concatenate the two files together, I created a text file "concat_list" with :&#xA;file &#x27;lec01_title_matched.mp4&#x27; file &#x27;lec01.mp4&#x27;, and ran the command ffmpeg -f concat -safe 0 -i concat_list.txt -c copy -movflags &#x2B;faststart output.mp4.

    &#xA;

    The main video is 53 minutes long, but the final output video after concatenating is 1 hour and 43 minutes long.

    &#xA;

    I'm looking for advice for how to create the "lecture title video" properly to match the parameters of the second video so that I can concatenate them without problems.

    &#xA;

    Here's the output of ffmpeg -i lec01.mp4 :

  • The error "Failed to query nvenc max version" typically occurs when using FFmpeg on Linux

    28 juillet 2023, par Well Chen

    The error "Failed to query nvenc max version" typically occurs when using FFmpeg with NVIDIA GPU acceleration (hevc_nvenc) on Linux.

    &#xA;

    Does anyone know how to solve this bug ? Thank you very much.

    I have installed FFmpeg, NVIDIA GPU drivers, and SDK. It works fine without using GPU acceleration, but it throws an error when using GPU acceleration.
