  • Deinterlacing in OpenCV

    17 avril 2017, par Yves Daoust

    I have a video stream stored in an MPEG file. Interlacing is strongly visible where there is motion and I need to de-interlace.

    When doing it by software (averaging every other line), the result is not satisfactory, strong artifacts remain at places.

    So I was wondering if it was possible to enforce deinterlacing somewhere in the decoding chain (which is ffmpeg), or even decode the odd/even fields separately. I am using the VideoCapture capture object, which doesn’t seem to provide any level of control.

    It could also be that the stream was MPEG’d without caring for interlacing, but I have no means to check that. To make things a little worse, OpenCV does not even return the FourCC of the stream.

  • Why does this code detects images as video and how can I fix it ?

    18 novembre 2022, par Arturo

    This method is detecting .jpg pictures as video. Why is that ? How can I fix it ?

    


    def is_video(self) -> bool:
    try:
        res = self.video_metadata['codec_type'] == 'video'
        logger.info(f"Video.is_video() -> {res}")
        return res
    except:
        return False


    


    I'm getting the metadata with

    


    ffmpeg.probe(self.path, select_streams = stream)['streams'][0]


    


    I'm using the metadata for more things, that's why I've used ffmpeg in this method.

    


  • How to make FFMPEG insert dynamic data in a video stream ?

    10 juin 2016, par Bepeho

    I’m trying to add an dynamic overlay to a file FFMPEG is generating for me.

    The overlay must display data received in real-time (let’s say the speed of a car where the video is being recorderd)

    Note that my question is not about displaying things in the video, but about how to have FFMPEG receive this data so it can display them.

    Has anyone done this before ? How ?

    Thank you
