Christoph Hohmann 5e768990f2 deps/libff: Fix that inputs are not closed when a demuxer is freed
avformat_free_context() only frees the memory used by an AVFormatContext
but it does not close the opened media file. This causes a leaked file
descriptor every time a media source frees a demuxer. Using
avformat_close_input() instead frees the context and closes the media
file.
