[Libav-user] [Phishing Risk] [Phishing Risk] [Phishing Risk] [External] Re: How to migrate atadenoise in ffmpeg to my own project?

[项首彦]

Or directly take the video frame in yuvI420 format as input, and then use atadenoise to reduce noise

The original format of the frame obtained from the encoder is YUV_I420, and then libyuv can be used to convert it to RGB24. I want to know what other information is needed to call the filter_slice API besides the video frame.
