There is almost 1000 of them without enabling much of any dependencies. So I think that's next to impossible.

Then this patch will make it harder to see new warnings within thousands of warnings, isn’t it? It’s annoying to enable this warning before fix those code first. > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".

It’s annoying to enable this warning before fix those code first. Well, the reality is, that without printing all these warnings, nobody will ever fix them. Unless someone sits down and spends potentially multiple days if not weeks of work to fix all the current ones. If we print all the warnings instead, it can get fixed gradually.

I can only agree with Zhao and Andreas here. If you want to turn a warning flag on, you have to eliminate the warnings first. Otherwise you're just drowning the existing and typically more serious warnings in a sea of new warnings. The result is obvious: people will just ignore *all* warnigns then, and that's worse.
