  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

    Since all my media players does not support rotate-knowledge, I have turned the video over again, and at the same time slightly decreased the resolution of command "ffmpeg -i "input.mp4" -vf "scale=720:1280,transpose=0,transpose=0" -c:a copy "output.mp4""

    This works very well in VLC, for example. However, Windows Media Player or Samsung TV does not play it. Windows Explorer does not even show a video thumbnail, so the video file is broken by Windows.

    Is not FFmpeg able to produce a standard MPEG4 file, or what the hell is this about ? I’ve tried all the alternatives presented, such as "-fflags +genpts", "-fflags genpts", "-movflags faststart", "-movflags +faststart", "pix_fmt=yuv420p" etc. but nothing worked.

  • Encoding 4K 60Hz lossless from a capture card

    Hi all,

    I’m trying to encode 4K 30/60Hz video in a lossless format from a 4K capture card and everything I’ve tried gives me a similar error as in the linked image, [real-time buffer too full or near too full frame dropped]

    [Not mine]
    https://cloud.githubusercontent.com/assets/4932401/22171307/ef5c9864-df58-11e6-8821-4b74ce3f32d0.png

    This is the command I’ve tried most recently :

    ffmpeg.exe -f dshow -video_size 3840x2160 -framerate 30 -pixel_format bgr24 -rtbufsize INT_MAX -i video="MZ0380 PCI, Analog 01 Capture" -vf fps=30 out%d.BMP

    With the images dumped to a 10G RAM disk or 850 EVO. I’m doing this to skip the encoding step.

    I get the same error when encoding with h265 lossless and NVENC h265 lossless.

    I need the video to be lossless as it will be used to test hardware h265 encoders.

    Video source is a 4K Blu-ray.

    Any help would be greatly appreciated. Thank you.
