  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Obscure error while transcoding a video with FFMPEG

    8 juillet 2016, par ZiggidyCreative

    thanks for taking a moment to look at this FFMPEG error i’m having. I’m trying to transcode any video file, recorded in portrait mode and crop it to a square using the top portion and then size it down to 600x600 square. Here is the command i’m using :

    ffmpeg -y -i input-video.mov -filter_complex '[0] crop=1080:1080:0:0, scale=600:600, split=2[out1][out2]' -map '[out1]' video/transcoded-video.mp4 -map '[out2]' -qscale:v 6 thumbnails/thumb_%03d.png

    Here are the errors :

    [swscaler @ 0x2502260] No accelerated colorspace conversion found from yuv420p to rgb24.
    
[swscaler @ 0x250a2b0] No accelerated colorspace conversion found from yuv420p to rgb24.

  • How to calculate vmaf score of multi-resolution webm using ffmpeg ?

    13 juillet 2022, par will

    I’m trying to calculate the vmaf of two videos, one is avi(rawvideo(I420), yuv420p), the other is webm(vp8, yuv420p). I uploaded test video and vmaf log here.

    


    But I found that if it’s a multi-resolution webm, the scores obtained with and without fps filter are quite different. Without fps filter the vmaf score is 34.670390, with fps filter the vmaf score is 56.339923.

    


    If it‘s a single resolution webm, there is no significant difference between the scores obtained with and without fps filter. Without fps filter the vmaf score is 65.527304, with fps filter the vmaf score is 65.480217.

    


    I use these commands.

    


    without fps filter

    I'm curious about what causes such a difference ? And how to calculate vmaf score of multi-resolution webm correctly ?

    


  • Metadict in ffmpeg does not have rotate information

    14 juillet 2022, par Lucky Sunda

    My aim is to extract frames out of a video but many times the frames are inverted. This is happening because "VideoCapture" in cv2 does read the rotate flag data present in the video metadata. I am running it on mac and installed "ffmpeg" package (5.0.1) using brew package manager. This is my code to check rotation present in a video using ffmpeg.

    


    import ffmpeg 
import cv2   
import pprint 
pp = pprint.PrettyPrinter(depth=4)
def check_rotation(path_video_file):
    # this returns meta-data of the video file in form of a dictionary
    meta_dict = ffmpeg.probe(path_video_file)
    pp.pprint(meta_dict)

    # from the dictionary, meta_dict['streams'][0]['tags']['rotate'] is the key
    # we are looking for
    rotateCode = None
    if int(meta_dict['streams'][0]['tags']['rotate']) == 90:
        rotateCode = cv2.ROTATE_90_CLOCKWISE
    elif int(meta_dict['streams'][0]['tags']['rotate']) == 180:
        rotateCode = cv2.ROTATE_180
    elif int(meta_dict['streams'][0]['tags']['rotate']) == 270:
        rotateCode = cv2.ROTATE_90_COUNTERCLOCKWISE

    return rotateCode



    


    Here the meta_dict is supposed to have information about the rotation but it is not there.
printing out meta_dict gives :

    Can someone please help me to find if rotation is present in a video ?
