I want to use the function 'static int filter_slice(AVFilterContext *ctx, void *arg, int jobnr, int nb_jobs)' as an API to process the frames output by the encoder. 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.
