Unfortunately it was deprecated, so I decided to write this one.
libav) and then I found the "How to write a video player in less than 1k lines" tutorial. Maybe I have accidentally changed some configuration.I was looking for a tutorial/book that would teach me how to start to use FFmpeg as a library (a.k.a. But I don't know how to feed parameters to it.Ĭurrently I use Xcode to set break point in atadenoise, but that's not stable. If I want to connect atadenoise to my project, I should start from filter_slice. Scale=78:24 transpose=cclock // assumes "" and "" to be input output pads respectivelyįprintf(stderr, "Usage: %s file\n", argv) Ĭonfiguring const char *filter_descr in this way to call atadenoise: const char *filter_descr = I call atadenoise function with the example code:ĭoc/examples/filtering_video.c // const char *filter_descr = "scale=78:24,transpose=cclock" Static void fweight_row#name#_serial(const uint8_t *ssrc, uint8_t *ddst, \ Int thra, int thrb, const float *weights) \ Therefore, the specific noise reduction method is selected according to the configured parameters: static void fweight_row#name(const uint8_t *ssrc, uint8_t *ddst, \
Which is used to call s->dsp.filter_row(src, dst, srcf, w, mid, size, thra, thrb, weights) Libavfilter/vf_atadenoise.c static int filter_slice(AVFilterContext *ctx, void *arg, int jobnr, int nb_jobs)
This is the entrance to the atadenoise filter:
