=====AV_PIX_FMT_RGB24=====

This is your standard 24 bits per pixel RGB.<br>

In your AVFrame, data[0] will contain your single buffer RGBRGBRGB.<br>

Where the linesize is typically <math>3 * width</math> bytes per row and <math>3</math> bytes per pixel.

=====AV_PIX_FMT_YUV420P =====

This is a planar YUV pixel format with chroma subsampling.<br>

Each pixel will have its own luma component (Y) but each <math>2 \times 2</math> block of pixels will share chrominance components (U, V)<br>

In your AVFrame, data[0] will contain your Y image, data[1] will contain your .<br>

Data[0] will typically be <math>width * height</math> bytes.<br>

Data[1] and data[2] will typically be <math>width * height / 4</math> bytes.<br>
