  • Qualité du média après traitement

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

    I’m trying to run these keyframes through an opencv human shape recognition api. It saves close to 300 keyframes to the folder I specified but for some reason the program just hangs afterwords instead of running the open cv hogger api on the newly saved keyframes. Will post script if it will help. Thank you for any help you can provide !!!

  • ffmpeg pipe output and script [duplicate]

    27 juillet 2018, par James Magnus

    This question already has an answer here :

    I need to extract raw video and pipe it to another program. This runs perfectly in a terminal :

    ffmpeg -i SampleVideo_1280x720_5mb.mp4 -s 1920x1080 -c:v rawvideo -pix_fmt yuv420p -f rawvideo - | ffplay -f rawvideo -pix_fmt yuv420p -s 1920x1080 -

    But when I try to run this command from a script it fails. Here is a very simplified version of the script :

    #!/bin/bash
    

    
c='ffmpeg -i SampleVideo_1280x720_5mb.mp4 -s 1920x1080 -c:v rawvideo -pix_fmt yuv420p -f rawvideo - | ffplay -f rawvideo -pix_fmt yuv420p -s 1920x1080 -'
    
$c

    The output

  • FFMPEG command (For capturing keyframe) executes, but not creating the output file

    3 mai 2017, par sforsandeep

    Im trying with an FFMPEG command using the latest FFMPEG exe. The command executes fine. But the output file is not being created.

    Here is the command I tried from DOS prompt. According to a colleagues comment, it was (The command) working before without any trouble.

    D:\Utilities\FFMPegVideoManager\FFMPEG_updated\ffmpeg.exe -i
    
"M:\content\video.mp4" -y -ss 1 -frames 1
    
"E:\frame\testtest.jpg"

    The output after the execution is
