  • Unable to properly save video in android ffmpeg app

    22 mars 2021, par connor449

    I am trying to record and save a video with an ffmpeg app on android 10. I'm very new to android/mobile development.

    


    Here is my manifest file :

    


    &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<manifest package="com.example.camera">&#xA;    &#xA;    &#xA;    &#xA;&#xA;    &#xA;&#xA;&#xA;    &#xA;        <activity>&#xA;            &#xA;            &#xA;        </activity>        <activity>&#xA;            &#xA;                <action></action>&#xA;&#xA;                <category></category>&#xA;            &#xA;        </activity>&#xA;    &#xA;&#xA;&#xA;</manifest>&#xA;

    &#xA;

    As you can see, I am specifying permission to read/write data.

    &#xA;

    Here is my mainActivity :

  • FFMPEG Video loop from images files

    27 février 2020, par Nesan Mano

    I am trying to make a video from a bundle of image files and then apply a an overlay on top of it.Another requirement is to make the video loop 3x. It is simply not working.

    The first three paths are pointing toward the same image bundle. (A folder containing images like the following DSC0001_0013.jpg,DSC0002_0013.jpg,etc)

  • "Pixel format 'yuvj420p' is not supported" when converting image to video using CUDA hardware acceleration

    11 février 2020, par laurent

    I’m trying to convert an image to a video using CUDA hardware acceleration but I can’t get it to work.

    The basic command I have is this one :

    ffmpeg -y -hwaccel cuvid -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

    And I’m getting this error :

    Error while decoding stream #0:0: Invalid argument

    I’ve tried setting the pixel format like so, but that didn’t help :

    ffmpeg -y -hwaccel cuvid -pix_fmt yuv420p -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

    I’ve also tried many other flags but can’t get anything to work. Any idea what the issue might be ?
