  • How can i burn in the current video playback percentage on to a video stream using FFMpeg

    25 mai, par David Clews

    I've taken alook at the drawtext filter in ffmpeg and it offers the ability to burn in the current local time directly on to the video stream. I would like this sort of behaviour but for a integer percentage value and the percentage symbol % after the actual value. I don't know if this is possible using FFMpeg on the command line. The formula should be something like.

    


    ceil((t/duration)*100)

    


  • How to increase video quality of combined video and audio file using ffmpeg

    29 juin 2022, par jettzeong

    I have a scraper script that I am using which utilizes PRAW module to scrape reddit for media.

    


    To downloaded reddit videos, I have written the code below :

    


            video_url = submission.media['reddit_video']['fallback_url'] 
        audio_url = submission.url + "/audio"
        print('Video: ' + video_url)
        print('Audio: ' + audio_url)
        video = requests.get(video_url).content
        audio = requests.get(audio_url).content
        videoname = "D:\\Bot\\reddit_scrape\\" + submission.id + '_video.mp4'
        audioname = "D:\\Bot\\reddit_scrape\\" + submission.id + '_audio.mp4'
        filename = "D:\\Bot\\reddit_scrape\\" + submission.id + '.mp4'
        
        with open(videoname, 'wb') as handler:
            handler.write(video)
        with open(audioname, 'wb') as handler:
            handler.write(audio)

        os.system(f"ffmpeg -i {videoname} -i {audioname} -map 0:v -map 1:a -c:v copy {filename}")
        os.remove(videoname)
        os.remove(audioname)
        save_to_dict(id = submission.id, ext = filename, txt = submission.title)


    


    What this code does is that it fetches the video and audio seperately from reddit, and combines them via ffmpeg.

    


    However, the video created by this block of code is very blurry and has low resolution.

    


    May I know what kind of argument I can use to make my video file play with higher resolution ?
