Mpv – A free, open-source, and cross-platform media player

I use it to inspect video frames by frames, particularly being able to go back one frame. VLC doesn't support it, this thread about the feature is hilarious https://forum.videolan.org/viewtopic.php?t=120627

The developer responds to a comment:

But many players are able to do it for years.

with:

If it's so easy, why are you not doing it?

He's not just a butthole, he's a stereotypical open source developer butthole. On the other hand, if he worked for Microsoft, he'd be claiming that it takes a PhD to do it...

The dev said they are happy to accept patch for this feature. Remember that you're not entitled to demand new features, as a (non-paying) user, you can't allocate dev's time to work on what you want.

This card is played too often by developers who only want to work on features they personally find interesting or worthwhile.

Yes, you realistically cannot implement everything every user wants, but at the same time your software is meant to solve problems. Keeping direct communication with your users, and understanding what they find useful or not, should be the driving force of the design and features of your app.

FWIW, I've been on both sides of this discussion, as an OSS maintainer and user, and have experience with demanding users and arrogant and, yes, _lazy_ developers alike. Let's stop the narrative that users don't have the right to request features because they're not paying customers, and that this is driving developers to burn out. Communication is key to producing useful software regardless of its license. OSS development in particular is not just about throwing some code online and forgetting about it.
