  • Rails FFMPEG - convert to webm gives error for encoder 'libvpx-vp9'

    7 mai 2019, par Milind

    I am testing video conversion to convert video file into mp4 and webm.
    I have also setup ffmpeg and compiled properly.Mp4 conversion succeeds but webm breaks always complaining as -

    The encoder 'libvpx-vp9' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

    its strange as I aready have vp8 present -

  • Render FFmpeg AVFrame as OpenGL texture ?

    5 mars 2019, par ZeroDefect

    I’m attempting to to render a jpeg image (1024x1024 pixels) in the form of an FFmpeg AVFrame as a texture in OpenGL. What I get instead is something that appears as a 1024x1024 dark green quad :

    dark green quad screenshot

    The code to render the AVFrame data in OpenGL is shown below. I have convinced myself that the raw RGB data held within the FFmpeg AVFrame data is not solely dark green.

    GLuint g_texture = {};

    Environment :

    • GCC v8.2

    EDIT : As per @immibis’ suggestion below, it all works when I change the rendering of the quad to :

    // Draw a quad
    
glBegin(GL_QUADS);
    
glTexCoord2f(0, 0);
    
glVertex2i(0, 0); // top left
    
glTexCoord2f(1, 0);
    
glVertex2i(1024, 0); // top right
    
glTexCoord2f(1, 1);
    
glVertex2i(1024, 1024); // bottom right
    
glTexCoord2f(0, 1);
    
glVertex2i(0, 1024); // bottom left
    
glEnd();
