Internal container module operates file descriptor to media file. For this purpose, the structure has fd member and any file operation is done internally. However, the case to use special file descriptor such as memfd requires to maintain file descriptor externally. This commit opens file descriptor outside of container module. The internal APIs to initialize container get an argument for the file descriptor instead of file path.
