 How do you think will this improve/affect Maemo?

I have to admit: I don't get Nokia.

So they invest in Maemo for several years, which is based on GTK.

Now they buy Trolltech, which is developing Qt, the competitor to GTK.

They also invest in three different (and more or less competing) browser
engines: Minomo/Mozilla (the new Maemo browser engine), Opera (the old
Maemo browser engine and used in several of their phones) and GTK
Webkit/KHTML (used for some of their phones).

While it's ok to keep all options open, it doesn't look like much of a
strategy right now.

Re: What does Nokia's acquisition of Trolltech mean to Maemo?

2008-01-28 Thread Hanno Zulla
Hi,

 Welcome to the world of large, multi-national companies. I don't
 imagine Nokia's MA teams were particularly mindful of the Qt/Gtk
 distinction in Maemo when they made the acquisition.

Yes, of course I'm aware of the dynamics inside a huge company.

But Nokia is a technology company, so I presumed that they do have a
strategy and now it seems that they don't. Or they can't decide on which
route to go and so they buy into all routes they can go.

The money that Nokia now spends on Trolltech could have been used to
assemble a killer team of own developers doing framework development. I
thought that Maemo was just that, an experiment to build an open source
framework that later might be used to develop closed-source phone
applications on top of it. Maemo turned out really nice and Nokia has
done great work for GTK so far.

But now that they bought the competing framework, this armchair
developer gets the impression that the experiment has failed. Has it?

 Because there is no way to download maemo easily and build your own

If I am not mistaken, this is not exactly true.

Maemo (as such) is free enough, some of the apps and drivers that Nokia
ships with its tablets are not. A competitor interested in building a
Maemo device should be able to adapt Maemo to its hardware and build
replacements for the non-free apps.

I wonder why this hasn't happened, yet.

DVD content playback possible or not? Re: Wishlist (was:Re: N800 and USB host mode)

2007-03-09 Thread Hanno Zulla
Hi,

 I'd like support for the IVA (Imaging Video Accelerator) device to be
 implemented, or at least for some more information to be made available if 
 Nokia
 can't justify the time.

 Rationale: 

 This hardware is supposed to be able to improve large image display and can 
 VGA
 decoding at up to 30fps. And again, it's just sat there.
 
 Right now, the biggest bottleneck in video decoding is RFBI bandwidth
 (i.e. the bus between OMAP and the LCD controller we use), being too
 slow to push more than ~15fps through at 800x480.  Beefing up the
 processor-side decoding doesn't help.  We've been working on this and
 the next firmware update will give you significantly faster video (with
 a couple of caveats).
 
 So it's mostly just down to the large image display, which more or less
 suffers from the same problem.  I don't think it would give us much
 benefit at all.

So from the hardware side, it is definitely no-matter-what-you-try
impossible to play DVD video content on the N800, even if there was help
from the DSP?

Video playback is my biggest wish for improvement on the N800. See
http://www.hanno.de/blog/2007/02/16/video-on-n800/ for some comparisons
of video playback on the N800 as it is today and how it could be on an
800x480 screen.

So far, I had hoped that the N800 might one day be able to play DVD
files from an SDHC card, once the existing hardware (as Simon noted) had
better support. Would be a giant pity if it's impossible.

Re: DVD content playback possible or not? Re: Wishlist

2007-03-09 Thread Hanno Zulla
Hi Daniel,

 DVD content is MPEG-2 video, which the N800 cpu should be able to
 decode. But DVD video is 720x480 at 30 fps (NTSC) or 720x576 at 25 fps
 (PAL), so reading from your previous message, I fear that the hardware
 is just incapable of playing it... Or isn't it?
 
 Unfortunately this is definitely not possible.  A quick
 back-of-the-envelope calculation suggests that we're only able to put
 about 7fps through at PAL even with the newer firmware.  This is a
 pure hardware limitation, and not something we can work around in
 software.  You'd have to reduce to about 400x320 at 25fps, or 500x400
 for roughly 15fps.

Boy, what a disappointment. I mean, really.

TI is advertising the chipset used in the N800 as dvd-capable and I had
the impression that the hardware was there, only the missing video
acceleration and dsp drivers were stopping us from watching full-screen
30fps video on the device.

I had also thought that a dsp had its own path to the video screen so
that it could decode video on its own.

I really, really like the N800 and Maemo is as cool as it can get, so
congrats on you guys' work so far.

But this is sad to hear.

 Why do you want DVD MPEG2 Playback?

Because it's there.

There's lots of content available in MPEG2, either on DVD or coming from
DVB broadcasts.

MPEG2 needs little CPU resources, is well understood by developers and
is well supported by several apps. Including vlc which even understands
DVD menus.

I would love to just copy a DVD disc image or a DVB recording to my N800
and watch it on the go.

 MPEG2 is IMHO not the way to go, it needs big files.

This is true. One DVD is up to 9 GB of data, but usually less.

SDHC is coming and the N800 can support it. Flash is getting cheaper by
the minute. In just a few months, 8 GB of flash storage on an SDHC card
will be affordable to anyone and 16 GB is just around the corner.

 Better support for MPEG4 and the media player is
 needed. Media Player often says playback of this format is not
 supported but the files play fine in mplayer. And AFAIK mplayer only
 uses the CPU and not the DSP. (Ok, it may use the MP2/3 DSP codecs vor
 audio decoding.)
 
 Better support for 400x240 MPEG4 would be fine. One can store about 5-6
 houres of video on a 2 GB card. With MPEG2 this would be only about 1h.

You are, of course, right that MPEG4 is far superiour to MPEG2.

But MPEG4 needs more CPU power AND you have to transcode the existing
material we already have on DVD or DVB before you can watch it. It's
kind of pointless to waste desktop CPU power to transcode existing
material if you could watch it in original form.

Hi,

 I'd rather transcode once into a format more suitable for portable
 devices than waste all my Flash storing the same single uncompressed DVD
 film/movie.
 
 It's about balance, and having the powerful desktop CPU convert the film
 as a one-off exercise is surely a better option than expecting more from
 a hardware-limited platform, or consuming all your available Flash
 memory to store the film in it's original state.

As Mike stated, the format isn't the problem.

(If I'm happy to put a full DVD on an SDHC card and you are not, so be it.)

Playback resolution is the problem and the hardware limitations will not
allow us to use the N800 screen as it is. That's a pity, alhtough I
understand the reasons for these limitations.

[maemo-developers] Dream Scenario (Re: Maemo roadmap, SDK improvements...)

2007-02-07 Thread Hanno Zulla
Hi,

to me, the relationship between Maemo's FOSS parts and Maemo's closed
parts are like the relationship between Ubuntu and its closed source
driver packages (NVidia, WLAN firmware, etc.). I would be nicest if
Maemo was distributed similar to that.


Dave Neuer schrieb:
 What exactly are asking for here: an official tarball release of
 everything in one tree? Pointers to svn tags for each component?

My dream scenario would be something that would easily allow non-Nokia
developers to build a working firmware binary that is equivalent to the
current official release, using as much source as possible. To do this,
one would need:

- An official deb-src repository of all open source Maemo packages
  written by Nokia
  (which developers can modify, build and package in Scratchbox)

- Another official repository of all closed source Maemo binaries
  (which developers can add to their own Scratchbox environment)

- A tool to prelink the software and create a firmware from these
  packages

The workflow for a non-Nokia developer would be like this:

- (Modify and) build all open-source packages that the developer is
  interested in using apt-get build-dep / apt-build / some similar tool.

- Install the closed-source binary blob packages the developers wants
  using apt-get (for those .debs which have no foss replacements)

- create a custom firmware, flash it

- Bingo


That way, non-Nokia developers can easily tinker with the open source
parts of Maemo and learn about the system's API to write alternatives
for the closed source parts (e.g. to replace the opera-based browser
with a browser based on gtk+ webcore, while keeping all the other parts
of Maemo).

Also, it would allow us to create custom firmware. E.g. a firmware that
 contains my language only or adds languages that Nokia doesn't support,
e.g. Japanese. Or a firmware that does not contain the RSS and the Mail
application, but still can play MP3s.


I don't know how naive or impertinent this dream scenario is and I hope
that the folks at Nokia like it, as it's not meant as a rude request.

So far, Nokia has made a great effort to allow non-Nokia developers
write applications for Maemo. However, it is obvious that people are
interested in working on Maemo's core itself to add small features and
remove minor nits. (I am.)

The dream scenario outlined above would make this possible and it
appears to be doable and manageable without the need for NDAs, as binary
blobs remain binary blobs.

Hanno

be faster than I am. Perl is relatively easy to build for various
platforms, incl. ARM.

 I've had no problems `apt-get install perl perl-modules' on my 770
 from the maemo repository. Not tried it on my N800, but - worryingly -
 the packages don't seem to be there:

Whoever built it didn't do that for the N800. So I guess it's a perfect
candidate for a MUD recipe so that this doesn't happen again.

 how about the following utilities which are already quite standard for

All three are not development tools, but applications. You might want to
port them, but I doubt that they are absolutely necessairy for development.

I see your need for a network sniffer, though I guess that one should be
easily ported to Maemo.

 2. Samba Server. Related to the above, the ability to easily pull and
 push files from a CIFS/SMB compatible PC (e.g. Windows XP, etc.) would
 be very useful.

I use scp. You might want to try sshfs based on FUSE if you are running
a Linux desktop; with it, you can mount the device's filesystem right
into your desktop's filesystem.

Me too. Actually, I'd like to be given the possibility to build a full
firmware image by myself. Those parts that are open buildable from
source, those parts that are not as pre-packaged binaries.

[maemo-developers] How to learn DSP development for N800?

2007-02-05 Thread Hanno Zulla
Hi,

I'd like to learn about how to write an app / a library that can use the
DSP for some basic multimedia stuff.

I'm looking for a simple example source for the N800 that does DSP stuff
to learn from it.

Any project you can recommend?

Thanks,

Hanno

 Well, do you want direct access to DSP or do you want to use just
 gstreamer?

I want to learn how to add new codecs to Maemo. So: Yes, I want direct
access to the DSP.

Basically, I'm asking for what Frantisek just described in his message
Maemo roadmap, SDK improvements... to this list:

 - example of simple hello world dsp task with working makefile
 including linking phase with dsp bios used on device

 - source of example audio/video sink - i.e. how to produce audio/video
 from the dsp task (=what code to call in dsp bios)
