  • I keep having the message "MovieWriter ffmpeg unavailable ; using Pillow instead." I want to save as MP4 an animation

    6 décembre 2023, par Enrra

    I am doing an animation :

    


    animation = FuncAnimation(fig, update, frames=len(time_values), interval=250, repeat=False)
with a simple frame update function, I want it save it as a MP4 format :

    


    animation.save(f'{save_path}/heat_map.mp4', writer='ffmpeg', fps=10)

    


    I get the error message "MovieWriter ffmpeg unavailable ; using Pillow instead."

    


    I tried to do the following :

    


    plt.rcParams['animation.ffmpeg_path'] ='C:\\ProgramData\\Anaconda3\\LIB\\site-packages\\ffmpeg'
FFwriter = animation.FFMpegWriter()
animation.save(f'{save_path}/heat_map.mp4', writer = FFwriter, fps=10)


    


    This gets me an error message :

    


    Traceback (most recent call last):&#xA;  File "Graph_V1-8.py", line 406, in <module>&#xA;    FFwriter = animation.FFMpegWriter()&#xA;AttributeError: &#x27;FuncAnimation&#x27; object has no attribute &#x27;FFMpegWriter&#x27;&#xA;</module>

    &#xA;

    and I also tried to do the following :&#xA;animation.save(f&#x27;{save_path}/heat_map.mp4&#x27;, writer=&#x27;ffmpeg&#x27;, fps=10, codec=&#x27;libx264&#x27;)

    &#xA;

    which also get me the error :&#xA;"MovieWriter ffmpeg unavailable ; using Pillow instead."

    &#xA;

    When I write :

    &#xA;

    pip install ffmpeg&#xA;Requirement already satisfied: ffmpeg in c:\programdata\anaconda3\lib\site-packages (1.4)&#xA;

    &#xA;

    Thank you in advance for your help

  • How to save a vedostream on an event using ffmpeg

    I want to record short video sequences of an online stream (IP CCTV or Internet) on a defined event.

    For example : I want to have two minutes before and one minute after an event occures stored in a output file.

    Is it possible to do this using ffmpeg (avconv) and what are the parameters to use.

    Thanks for your help !
