hdsenc already had an explicit function to free all allocations in case of an error, but it was not marked as deinit function, so that it was not called automatically when the AVFormatContext for muxing gets freed.
Using an explicit deinit function also makes the code cleaner by allowing to return immediately without "goto fail".
