lavfilters - does movie filter in ffmpeg 4.3.1 support png format picture

Question

I use ffmpeg's moive filter to add wartermark on my video. The str is "const char *filter_descr = "movie=test.png:seek_point=3.2, scale=180:-1, setpts=PTS-STARTPTS [over];[in] setpts=PTS-STARTPTS [main];[main][over] overlay=16:16 [out]";" it shows that can't find codec, but if the wartermark picture is bmp ,then it's ok. I found that the png code exists in ffmpeg, it should support png decoder.
