I use wmav2 encoder in ffmpeg whose codec id is AV_CODEC_ID_WMAV2, sample format is AV_SAMPLE_FMT_FLTP. If input sample format is AV_SAMPLE_FMT_S16, does ffmpeg have wmav2 encoder whose sample format is AV_SAMPLE_FMT_S16? or I need write conversion routine for different sample formats? Does ffmpeg have some functions that convert one format to another?
