Media player for Qtopia Core
Message 1 in thread
Hello
I am interested in playing streaming video on Qtopia core commercial
version. The movie will be a MPEG4 stream over RTP/UDF. What are the
alternatives, seems like the Helix media player is integrated with
Qtopia, but can it also be used when running Qtopia Core? Are there any
alternatives that can be used? I have read that there is support for
Gstreamer on
http://doc.trolltech.com/qtopia4.3-snapshot/qtopia-dependencies.html ,
but is this integration available on Qtopia Core also?

The AVR32 based STK1000 development board uses "mplayer"
in QVGA full screen mode.
Do you need to run it in a window?

Hi Johan,
I have been experimenting with Qtopia configured with gstreamer. By
adding the gst-ffmpeg package to my target filesystem, I have been able
to see MPEG4 video files. I have not gotten the MPEG4 file audio
working yet, but I believe it just requires the addition of faad2
(gst-plugins-bad looks for this at configure time), and I have only
tried local files, not streaming.
If you want to use gstreamer without Qtopia, you might check the
gstreamer application development manual for how to create a player
using the "playbin" element.

Qtopia core is badly named. It's actually more akin to Qt for Embedded.
As such, none of the work done for Qtopia is available for it. I suggest
possibly looking at the opie project, and porting one of the mplayer
frontends from Qt 2 over to Qt 4. I've also heard VLC is working on an
embedded frontend. There's a fair amount of work tho.
As to helix/gstreamer, you'll have to purchase the full qtopia to get those.

Actually, these are available for the open source version as well.
Except that helix code must be downloaded separately from the helixcommunity
web site, and cannot be distributed (binary or sources), unless you have a
license agreement with Real.

Something I stumbled across today that may be of help, it's a Qt wrapper
around libxine.

May accelarate development for you to almost not quite "from scratch".

Hi Johan,
Qtopia Core 4.4(the next release) has a new feature called Phonon, which
allows cross-platform media playback. It does this by using the various
media frameworks for each platform as back-ends, presenting them in a
unified API. For Linux (and thus Qtopia Core), the backend is GStreamer.
If you want to have a look at the Phonon API before 4.4 is released,
checkout the documentation for the 4.4 nightly snapshots
(http://doc.trolltech.com/main-snapshot/index.html, in particular
http://doc.trolltech.com/main-snapshot/phonon-overview.html). You can
also download the source for the nightly snapshots under the GPL at
(http://doc.trolltech.com/main-snapshot/phonon-overview.html).
Cheers,
Tom
