This parameter is used to ensure that for a given input, the output
frames are always identical so that it can be compared against
a reference in automatic tests.

Seeing it like this I am still not happy with this.
So by default the data is stable (good!). But while disabling this option does
indeed make the data unstable, the real reason why you want to do that is to get
the addition information.
So this module name is just weird.
It is more a TPG info level that you provide here. Perhaps "tpg_verbose" is a better
name?

That will also change this condition to 'if (tpg_verbose)' which is better then
negating a boolean.

I'm a bit unhappy about the amount of code churn here.
A lot of the time it prints a timestamp + buffer index. Perhaps a small
helper function will help:
visl_print_ts_idx(&buf, &buflen, "backward_ref_ts", ts, b_ref);
That helper only prints the vb2_idx if enabled, and it can also omit it
if the vb2_buffer pointer == NULL.
