  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • C# Process in loop reading error output, causes "No async read operation is in progress on the stream" error

    29 mai 2023, par TSLee

    I am trying to read the format of multiple video files using ffmpeg in an asynchronous operation of Process and facing an error, "No async read operation is in progress on the stream". According to https://social.msdn.microsoft.com/Forums/vstudio/en-US/c961f461-7afb-4a92-b0ae-f78c2003b5de/help-an-asynchronous-read-operation-is-already-in-progress-on-the-standardoutput-stream?forum=csharpgeneral, I think I have to use CancelErrorRead(), as BeginErrorReadLine() can't be launched more than once. I also wonder if I use this function in the wrong place, because the read operation has ended in process1.exited() ? But the operation can't proceed to the second index with this error.

    


    How could I use CancelErrorRead()/CancelOutputRead() properly and where should I place them on the code ? I also did an experiment in that I commented these two CancelRead(), and a different error "async read operation has been started on the stream" will appear.

  • How to make an automated video of changing webpage

    21 mars 2023, par jonas wouters

    I'm currently working on a project where I need to make a recording of a webpage without opening this browser. (headless browser)
The file I'm working on is stored locally on my machine and is generated with a Python script. It's generated because it will be different for every user and will be deleted after the recording is made.

    


    I'm currently stuck with trying to make a recording of a webpage.
Does somebody know how I can record a webpage.

    


    Currently I'm doing this

    


    # Make a video
def create_video(duration, name):
    # Path of the HTML file you want to record
    html_file_path = os.path.join(py_dir_path, 'templates/video/', f'{name}.html')
    width = 1080
    height = 1920
    framerate = 30
    
    options = Options()
    options.headless = True
    options.add_experimental_option('mobileEmulation', {'deviceName': 'iPhone SE'})
    driver = webdriver.Chrome(options=options)
    driver.get(f'file://{html_file_path}')
    print(driver)
    outputName = f'{name}.mp4'

    cmd= f'ffmpeg -y -f xcbgrab -s {width}x{height} -framerate {framerate} -i :0.0+0,0 -f alsa -i default -vcodec libx264 -pix_fmt yuv420p -preset ultrafast {outputName}'
    p = subprocess.Popen(cmd, shell=True)

    import time
    time.sleep(duration)

    p.kill()


    


    This code makes a headless browser and plays the website, but the recording process is not working for me

    


    I've already have had working code, but this was based on making screenshots of the webpage and then pasting these screenshots after each other, this code was difficult to read and worst of all very slow.

    


    Working bad code

    


    # Make a video
def create_video(duration, name, timesFaster):
    # Path of the HTML file you want to record
    html_file_path = os.path.join(py_dir_path, 'templates/video/', f'{name}.html')
    # Use function create_driver to create a driver and use this driver
    try:
        # Make a chrome window with size --> width: 390px, height: 850px
        options = webdriver.ChromeOptions()
        options.add_argument("--headless")
        options.add_experimental_option('mobileEmulation', {'deviceName': 'iPhone SE'})
        driver = webdriver.Chrome(options=options)
        driver.get(f'file://{html_file_path}')
        
        # Use function capture_screenshots to take screenshots for 
        capture_screenshots(driver, int(duration), name, timesFaster)
    finally:
        driver.quit

# Make as many screens as possible in ... amount of time (... = animation_duration)
def capture_screenshots(driver, animation_duration, name, timesFaster):
    screenshots = []
    # Calculate the ending time
    end_time = time.time() + animation_duration
    # Keeps track of amount of screenshots
    index = 1

    try:
        # Take as many screenshots as possible until the current time exceeds the end_time
        while time.time() < end_time:
            # Each time a new filename (so it does not overwrite)
            screenshot_file_name = f'capture{index}.png'
            # Save the screenshot on device
            driver.save_screenshot(screenshot_file_name)
            # Append the screenshot in screenshots ([])
            screenshots.append(screenshot_file_name)
            index += 1
        
        
        # Calculate the FPS
        fps = (len(screenshots)/animation_duration) * timesFaster
        print("sec: ", animation_duration/timesFaster)
        print("fps: ", fps)
        # Make the video with the FPS calculated above
        clip = ImageSequenceClip(screenshots, fps=fps)
        # File name of the result (video)
        output_file_path = os.path.join(mp4_dir_path, f"part/{name}.mp4")
        # Write the videoFile to the system
        clip.write_videofile(output_file_path, codec='libx264', bitrate="2M")
    finally:
        # Delete all screenshots
        for screenshot in screenshots:
            try:
                os.remove(screenshot)
            except:
                pass


    


    At the moment it's not that important for me that it's a local file, if I would be able to record a webpage (for example https://jonaswouters.sinners.be/3d-animatie/) this will be equally helpfull

    


    Thanks in advance
Jonas

    


  • How could I add an overlay to a video based on mouse cursor coordinates ?

    5 mars 2023, par Dima

    I am making a web app, where the user clicks through some images while talking about them and pointing things out with the cursor. The audio, timestamps of image changes, and mouse cursor coordinates and times are sent to a php script which uses ffmpeg to make a slideshow from the images and audio.

    


    Then it runs another ffmpeg command to overlay a moving image representing the cursor hundreds of times to mimic the user's mouse movements.

    


    Here is an example command that inserts the mouse overlay :

    And this is just from a four second video. When I tried to do thirty seconds worth of mouse movements, the command would not even run because there were too many arguments. So I need to come up with another way to add a mouse overlay.

    


    An obvious choice would just be screen recording the user's screen to not have to add a mouse overlay because it would already be there. But then I don't think I can use full resolution pictures in the final video. It will be recordings of the images at whatever resolution the user's screen is set to. (Unless there's a way around this that I don't know about.)

    


    So how could I take a long list of mouse coordinates and timestamps and add an overlay representing a cursor to an existing video ?

    


    Edit : I tried putting everything from the filter-complex argument into a text file and calling it with filter_complex_script instead, as @БаярГончикжапов suggested in comments. Now it at least starts to run, but every time fails with this error :

    It only happens if there are more than 1553 arguments, and changing the arguments for 1553 and surrounding ones doesn't stop the error.
