Extract RGB values from a AVFrame (FFMPEG) in C++
I am currently trying to read in video frames by using FFMPEG. The format is PIX_FMT_RGB24; For each frame, the RGB values are all combined together in frame->data[0] (Where frame is of the type AVFrame).
How do I extract the individual R, G and B values for each frame? This is for processing the video. I would think it would work the same way as extracting the RGB values from a bitmap too. Thanks!
My guess:
int p=x*3+y*frame->linesize[0];
r=frame->data[0][p];
g=frame->data[0][p+1];
b=frame->data[0][p+2];
I might have r, g, and b backwards. And there's a lot of room for speedup.
