Replace plain text response lines with dynamic query string on Nginx

I'm setting up the secure_link_module on Nginx to protect direct access to .m3u8 files, I was able to successfully configure it using an encrypted md5 and expires as query parameters, e.g:

example.com/video/sample.m3u8?md5=XXX&expires=YYY

that is working great for m3u8 files, but the problem is that inside .m3u8 files that are several .ts files, and in order for it to work, it also must be accessed with the query strings (sample.ts?md5=XXX&expires=YYY), I tried to use the ngx_http_sub_module with:

sub_filter_once off;
sub_filter ".ts" ".ts?md5=$arg_md5&expires=$arg_expires";

but unfortunately, it didn't work.

is there a simple way of search and replace line per line of the response with nginx?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
