  • ffmpeg producing empty MP4 files

    3 mai 2017, par Joshua Dowell

    I am trying to use ffmpeg to convert MTS files to MP4 files. It seems as though the command is running correctly, but the resulting files end up being empty.

  • How to export video as .mp4 using openCV ?

    6 juin 2017, par Riko

    I am trying to export video as .mp4 with openCV. I have tried several codecs but for now I had no success.

    This is a function that constructs a video from frames :

    def create_movie(self, out_directory, fps, total_frames):
    
    img1 = cv2.imread("temp/scr0.png")
    
    height, width, layers =  img1.shape
    
    codec = cv2.cv.CV_FOURCC('X','V','I','D')
    
    video = cv2.VideoWriter(out_directory, codec, fps, (width, height))
    

    
    for i in range(total_frames):
    
        img_name = "temp/scr" + str(i) + ".png"
    
        img = cv2.imread(img_name)
    
        video.write(img)
    

    
    video.release()
    
    cv2.destroyAllWindows()

    I usually get next error message, using different codecs :

    Tag XVID/0x44495658 incompatible with output codec id '13'

    Is is possible to do this and how ?
