Comment:

 The ```>``` syntax is handled by shells, and ffmpeg is not a shell, nor
 does it invoke one, and therefore it will never understand that syntax.

 If you want to write into filesystem object ```test_channel.mp4```, then
 use it as output, nothing else. The principle of named pipes is that they
 are not different from plain files for basic operations.
