  • How to cut using ffmpeg using start and end time not duration ?

    16 octobre 2020, par Joan Venge

    I have seen many links that shows specifying the start time and duration but I want to specify the start and end time. From example from 5 min mark to 12 min mark. How to do this using ffmpeg ?

    


  • mp4 video plays from beginning while seeking to another time [on hold]

    13 août 2013, par user2649860

    i am using lighttpd and h264 with jwplayer. I am trying to stream the MP4 video.

    My problem is that the MP4 video downloads whole file before playing and i have another problem i.e. when i seek to another time/point the video plays from beginning and it plays after the end time also.

    i have already tried the ffmpeg tools to create the h264 video and qt-faststart.exe tool to fix the video index problem of the video. But it does not work.

    Any solution ?? THanks in advanced

  • Overlay different images with different time span to a video

    26 juillet 2015, par azri.dev

    I need to overlay a video with ’different images’ at ’different time span’.
    Using python and ffmpeg I developed a code which do exactlly what I need but it is time consuming and not efficient in processing.

    The code is just loop over all the images (with their time span) and output new video file which will be an input for the next loop.

    Here is my code :

    def insert_photos_to_video(photos_to_add_array, input_video):
    
    count = 0
    
    position_x = 25
    
    position_y = 25
    

    
    image_position =  str(position_x) +':'+ str(position_y)
    

    
    for item in photos_to_add_array:
    
        image_path, time = item
    
        start_time, end_time = time
    
        output_video_name = str(count) + '.mp4'
    
        output_video_file = os.path.join(os.getcwd(), output_video_name)
    

    
        if count == 0:
    
            input_video_path_name = input_video
    

    
        command = 'ffmpeg -i '+ str(input_video_path_name) +' -i '+ image_path +' -filter_complex "[0:v][1:v] overlay='+ image_position +':enable=\'between(t,'+ str(start_time) +','+ str(end_time) +')\'" -pix_fmt yuv420p -c:a copy  '+ output_video_file 
    
        subprocess.call(command, shell=True)
    

    
        input_video_path_name = output_video_file
    

    
        count = count + 1
    

    
    return output_video_file
    • Is there any way to improve the code by combining all input images (along with their time span) in one ffmpeg command ?
    • Is there any other good way to do the above task with python using other libraries (e.g. OpenCV).

    Thanks in advance.
