There was a problem hiding this comment. Nit: In these three lines (96-98), use different input and output filenames to make the tests more realistic. I.e., replace the first "${ENCODED_FILE_STDIN}" with "${INPUT_Y4M}". Note: The input file should exist so that these three avifenc command lines succeed if |

I haven't read the pull request. I have a question: where is the position of this fictitious file path argument?
Here is my expectation:
-ooption, the fictitious input file path argument is right before the output file path argument.-ooption is used, the fictitious input file path argument is at the end of the command line.Is this what you implemented?

I have now read the pull request. What you implemented is not exactly the same as what I expected in how the options with update suffix (i.e.,
pendingSettings) are handled. This is perfectly fine because there are several reasonable ways to handle this. Since people's expectations may be different from what is implemented, it would be good to document somewhere how we handle the options with update suffix when--stdinis specified.
