Dear community, I have a opevCV Mat frame, call it mask. I decode frames into AVFrame, convert AVFrame to openCV Mat and encode them into AVPacket again.
Now, I want to add an alpha channel to my resulting video. Can you help me with that? - FYI, I tried to add alpha channel to openCV Mat and convert it to AVFrame. But it fades whole the video and it mars the color distribution. Best Davood Falahati ______________________________________________________
