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
- 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.
