Hello, How can an AVFilter determine whether its input is VFR or CFR? If the input is CFR, how can it get the frame rate in FPS? I would like to do this in advance of processing any frames, that is, in init() or config_input(). Please see the implementation below:
static int is_vfr(AVFilterLink *inlink) { return ???; // what goes here? } static float get_cfr_fps(AVFilterLink *inlink) { return 1.0f / av_q2d(inlink->time_base); // is this correct?? } static int config_input(AVFilterLink *inlink) { float fps; if (is_vfr(inlink)) { av_log(ctx, AV_LOG_ERROR, "This filter does not support VFR video.\n"); return AVERROR(EINVAL); } fps = get_cfr_fps(inlink); ... } Thanks in advance...
