  • ffmpeg : How do I create a 1 second video of 23 frames ?

    8 septembre 2022, par Sprout Coder

    I have 23 frames :

    


    frame-1.png
frame-2.png
....
..
frame-23.png


    


    Each frame is 15840PX x 15840PX and around 240Mb in size.

    


    I'm trying :

    


    ffmpeg -r 23 -i "frame-%d.png" -c:v libx265 -r 23 out.mp4


    


    and what I get in the end is a 12Mb video of 00:00 duration with no image

    


    Also, right before the command completes execution (it takes quite some time obviously) I get :

    


    [1]    12580 killed     ffmpeg -r 23 -i "frame-%d.png" -c:v libx265 -r 23 out.mp4x


    


    on the terminal.

    


    I don't know if that means it failed or whether it's a normal log after completion.

    


    Is my command wrong or is it impossible to execute due to the size of each frame ?

    


    Thank you in advance for your help

    


  • How to convert video programmatically using ffmpeg

    1er août 2018, par JasonStack

    Most applications of ffmpeg both in terminal and code seem to be passing ffmpeg commands to the ffmpeg library with specific parameters. For example, you might run the following command to get an overlayed gif out of a video input and a png input :

    -i i.mp4 -i me.png -filter_complex 'overlay' -pix_fmt yuv420p -c:a copy output.gif

    Is it possible to work with the library without using commands and only programmatically ? For example, by creating an FFmpeg object, passing it relevant parameters and then reading the output file from a specific directory, preferrably using C++ or Java.

  • FFpmeg attaching album cover to the audio is not working with Rails

    10 avril 2015, par Shilpi Agrawal

    I have some audio files of web format and i want to attach some album cover to those files. My native ffmpeg command works fine in terminal.

    ffmpeg -i audio.webm -i cover.jpg -map 0:0 -map 1:0 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (Front)" out.mp3

    But when i run the same command in my rails app, its telling me this error :
    Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument.

    Any suggestions ?
