Is there an easy way to check it, apart from converting a small dummy file using the codecs that I want to check and then reading the file's metadata? FFmpeg is an open source library for encoding and decoding different types of media files, generally MPEG and MPEG-based files. 1 Options The following options are mapped on the shared FFmpeg codec options. According to it, every codec needs to have 3 basic functions to be defined and these functions are assigned to function pointers of the structure AVCodec. ujosifojiqpmvhwarwsscwogfttqkdgmmuydfxfyusnpxmsotxr
