The Svace SAST tool have found an issue in using of ngx_rtmp_exec_run function. The function has ngx_int_t return value type but this value is never checked throughout the code. For example:

All functions that call ngx_rtmp_exec_run are also static void functions so they can't send that value further up and it it's not convinient thing to do.

ngx_rtmp_exec_run prints all required debug data to logs and we won't lose anything if we remove return NGX_ERROR or NGX_OK values and SAST tools will stop triggering on those.
