    19 décembre 2018, par Manza

    This question already has an answer here :

    I’m trying to render a animation.ArtistAnimation object into a 24 fps video file in format mp4.

    I have search about and I reached this. However, even after compiling ffmpeg I get this error message :

    C:\Users\trite\OneDrive\Documentos\MusiTex\Python\venv\Scripts\python.exe 
    
"C:/Users/trite/OneDrive/Documentos/MusiTex/Python/venv/Saving Animation.py"

    return self.avail[name]

During handling of the above exception, another exception occurred:

RuntimeError: Requested MovieWriter (ffmpeg) not available
    

    
Process finished with exit code 1

    What is the problem with ?

    I would really appreciate if you can help me. Actually, if there is other ways to saving/render this kind of object into a video file (preferably mp4) I will be delighted to hear them.

    Thank you very much

  • Using ffmpeg, extract small part of .m4a audio file and set extract file duration correctly

    30 août 2015, par Kes

    I have Linux mint 17.1.

    When I use ffmpeg to cut out a section of a 4 hour long .m4a audio file as follows :

    ffmpeg -ss 0:10:00 -i in_file.m4a -vn -c copy -t 0:40:00 out_file.m4a

    the correct position and duration of extract is extracted and the file plays just fine, but the audio duration meta-tag in the playback player is incorrectly shown as 4 hours.

    How can I set the actual extract duration so it is correct, in this case 30mins, or even better get ffmpeg to calculate it and set it properly ?

    Thank you

  • How can I convert multiple images to a video file while keeping the same file name ? [duplicate]

    13 juillet 2015, par Ertzi

    This question already has an answer here :

    My intention would be to get at the same time, picture1.jpg, picture2.jpg, picture3.jpg to video format such as picture1.mp4, picture2.mp4, picture3.mp4.

    I am currently using Mencoder and Linux bash code mencoder mf: //*.jpg -mf w = 1366: h = 768: fps = 6/60: type = jpg -ovc copy -oac copy -o images.mp4. But this command makes all the images into one video file (images.mp4).

    Can I do it with mencoder or ffmpeg ?
    My linux bash coding skills are basic.
