# Can the tools use FIFOs, pipes or standard output/standard input for reading/writing?
## The problem
Use cases include uploading or playing a file while muxing is still in progress.
## The answer
No. All of the tools in the MKVToolNix package rely on their input and output files being fully seekable. FIFOs, pipes and standard input/output are not. Therefore they cannot be used.
At the moment there are no proper error messages if you try to use a FIFO as an input or output file. However, the resulting files are most likely cut off or incorrect.
