Re: [Interest] Phonon video
Phonon is highly dependent on the back-end and in case of the video-player,
especially on the quality of the available codecs... on Windows, I've had best
results with the codecs from
http://www.windows7codecs.com/
I can assure you that Phonon still works this week :). But surely, Windows
updates can ruin your live... and it's not a problem of Qt / Phonon.

Hi people,
I've been trying to figure out why phonon suddenly doesn't work anymore.
It plays audio just fine but not video. I'm completely stuck.
I built and ran the qmediaplayer demo and saw the same thing, so it's
not my code. And the same code plays the files just fine on Linux. But
just for reference, here it is anyway:
mPlayer = new Phonon::MediaObject(this);
mVideo = new Phonon::VideoWidget;
Phonon::createPath(mPlayer, mVideo);
if (!mPlayer-hasVideo()) {
qDebug() Phonon video sink is not available;
...
}
hasVideo() returns false, and any attempt at adding a video file to
Phonon gives me a Pause Called in the debug output window. This is the
code used to play a file:
mVideo-show();
mVideo-resize(200, 200);
mPlayer-enqueue(Phonon::MediaSource(filename));
mPlayer-play();
Calling Phonon::BackendCapabilities::availableMimeTypes() gives me a
list of 54 mimetypes with both audio and video types in it. The files
I'm trying to play are supported, and Windows Media Player plays them
just fine.
Now here's the really strange part: Last week it worked. But suddenly,
video playback is gone. I have no clue what happened in between. I might
have updated Windows, but if that breaks Phonon, we have a real problem.
I can see that the DS94 backend is still there in both my 4.8.0 and
4.7.4 plugins.
This really worries me. The code is for a customer with an embedded
system that's going to be deployed on machines in many countries.
Calling those back to fix a Phonon problem *is not* an option. If Phonon
can't deliver a stable environment (and I currently seriously doubt
this), I will have to ditch it.
I obviously tried to search the net for this, and found plenty of people
with the same result. But none with a solution for it. I hope someone
here can help.
I'm on Windows 7 x64 and Windows XP 32 bit, using a fully updated SDK
2.4.1 with both visual studio 8 and mingw compilers and Qt versions

Re: [Interest] Phonon video
Hi Jason,
Thanks for the attempt :)
As I say in the description, it worked last week, now it doesn't. So
it's not a question of installing working codecs, because I didn't
uninstall any of them.
Also, when I first tried to play the files we use, WMP wasn't able to
play them, so Phonon wasn't either. Then I installed the codecs, and
both were able to play them. Now, only WMP can play the files.
About the QtMultimedia: The detailed description of the module says The
functionality provided by the Phonon Module is on a higher level and in
many cases more suitable for application developers.
But maybe I have to use it if Phonon is broken beyond reasonable repair.
Bo.

I would suspect that something in the DS filter graph changed. Verify you
have a valid path for the file type you are trying to play:

Keep in mind you still need to install video codecs because mingw version of
Qt does not work with Windows7's new media interfaces. Installing K-Lite
Codec pack usigally works for me.

[Interest] Qt 4.8.1 and chunked transfer encoding returning 0 size
Hi Everybody, I've just upgraded from 4.8.0 commercial to 4.8.1 commercial on Win 7 64 bit. The program accesses a server using HTTPS POST. When the response size is less than about 170Kb everything works as before. With larger responses, the raw headers also include Transfer-Encoding with value chunked. In the network finished slot, readAll then returns an empty QByteArray. Is there something else I need to do to get chunked encoding to work in 4.8.1? 4.8.0 was happily returning responses over 630Kb.

I think we should be able to paint to a HTML5 canvas. I created the attached PoC, modeled after QPicture. See main.cpp for an example. The code is released with the following license: USE: Use at your own risk. Use it as you wish with no warranties or fitness expressed or implied. COPYING/DISTRIBUTION: Don't claim the original code is yours, that would be wrong. Please attribute the original code to me. (It's a resume thing) It is your responsibility to put my email address in the file headers. You may use the code in Open and Closed Source projects, and assign what ever license and copyright as you wish. I don't assert any copyright, just credit. Details: The rendering is pretty good I've noticed fonts are not pixel-perfect but pretty close. The HTML5 canvas system (at least in FireFox) needs a 0.5px offset to generate a line properly, so things may be a tad off. If you browser supports HTML I'm attaching sample output.

Hi Sherif, Generated makefiles for nmake or generated vcproj for visual studio, depending on which TEMPLATE you used in your .pro file. app / lib == makefiles vcapp / vclib == .vcproj As Thiago said, the convenient way to do this is add -tp vc to qmake's command line, if you TEMPLATE is app or lib.
