Hello again,I'm glad that the topic I raised is somehow of interest, but I
noticed that, as usually good technicians do, you guys went straight into techy
bits, forgetting what the original post spotted.They say that when you are
aware of a problem you have it 50% solved.What concerns me is the remaining
50%, and since plans (and money) move this world, I would kindly ask if someone
is in charge of making a plan to address the QtMultimedia issues and making it
a quality part of the Qt framework.
For example, what sounds a good plan to me is something like: we'll dedicate
the necessary resources to close all the JIRA issues for version 5.5. OK...80%
would be fair enough :)Just an example that includes numbers and a time line.
Discussing the bits without a plan, is like discussing the sex of the angels
(like we say in Italy) as nobody will do anything in the end.
Random notes on the various replies:- 2 years ago, Phonon was exactly the
reason why I decided to write my own implementations on Qt4. I was scared of
the consequences of deploying on 3 platforms with it (IF that was ever
possible). Maybe now the situation is different, but there's Android and iOS
and I still would not go to Phonon anyway.I don't understand why everybody
wants to walk their own way. Why can't you Phonon guys help on QtMultimedia
(you could have joined in 2012...) instead of advertising a module by telling
people which flags they need to use to build it ? Are you aware of how
difficult it is to build ANYTHING with MinGW on Windows ? (and no, I won't use
M$ compilers, thanks)
- I agree with everybody that cross-platform multimedia integrations are a
tough job and a quite delicate matter. But once it's done it's done and the
bright side of the thing is that Qt has a super vast community that gives
feedback on different OSes, hardware and usages.
- I super agree with Lars. The Qt promise of writing code once and deploying
everywhere is the key of it all. If this isn't met, then it's not Qt anymore.
- I haven't really got an opinion about issues-oriented donations, but you
might end up having 200 $20 donations for 200 different issues. Then which one
will you solve first ?
Cheers,Massimo
