I found a video that shows that such boot on screen is possible in N900. http://www.youtube.com/watch?v=yri4qOfP8T0 This requires a custom kernel, IIRC fb console had some problems in the 2.6.28 n900 branch.

Re: Low Latency Audio Capture on the N900, QAudioInput BUG: has 5000msec latency, Meego audio future
I know that I'm a bit a repetitive person, but my intent is to raise an alarm, that nowadays companies cannot afford to ship, half-finished, half-baked, buggy systems, and moreover chose the vastly inferiour (pulseaudio) open source component over the better (JACK2 audio server). I reported my findings here, on the maemo-developers mailingslist, which is read by Nokia engineers too, and the only responses I get back is that I should not whine. No technical responses at all, how the latency can be lowered using other APIs etc.. Sadly, this week Nokia stock again dropped like a rock, while Apple gets preorders for 600k Iphone 4 in a day and have trouble to process all the orders. Does that not ring alarm bell at Nokia ? As said nowadays either you deliver a smooth user experience (including dropout free, low latency audio for apps) and make it easy for developers to access that features, or your market share will continue to drop and drop. It seems like Maemo will be end of lined soon so I'm not expecting Maemo getting much improvements, but it's successor, Meego HAS to deliver a smooth user experience. I will continue those discussions on the Meego list and perform benchmarks and tests so that everyone can see what the real numbers are and if there are still problems regarding low latency audio. Unfortunately, given the weak implementation of pulseaudio I fear that the prerformance will not be stellar. I hope that I'm proved wrong Did Meego enginers publish such numbers, yet ? eg what latency can be achieved on certain hardware, audio dropout frequency etc ? Execpt for technical discussions about audio I will not continue my long diatribes on this list. But as said I will continue to point out possible flaws in Meego regarding audio backing my claims up with numbers and bencharking apps.

The actual responses from both myself and Ville were that you're really not in the right place for this kind of discussion, both technical and political (= forum). Not to stop whining. Perhaps if you listened to that, you'd get feedback of the type you're after. But as said I will continue to point out possible flaws in Meego regarding audio backing my claims up with numbers and bencharking apps. By all means. Just make sure you point them out in the right place. If you're running MeeGo (as you keep mentioning), point them out to the relevant channels inside MeeGo. (hint: probably not maemo-developers.) OTOH, if you've found problems in Qt, which is as I recall the only concrete issue you have mentioned so far, please report them, to Qt, so they can be addressed.

RE: Low Latency Audio Capture on the N900, QAudioInput BUG: has 5000msec latency, Meego audio future
Benno, Out of curiosity, why not just compile it yourself? According to the Jack2 and PulseAudio sites they can work together with PA automatically releasing the sound system for J2 when J2 needs it using DBUS. So rather than complain about it; just port it real quick and then you will have actual numbers and the component you need to continue your work on your main project. :-D I'm not saying you aren't right that J2 offers a lot; it just that I would venture a educated guess that Nokia will NOT waste resources to change the underlying sound system on a OS (Maemo) that is at a EOL status.As for Meego, you need to obviously present a case on the Meego mailing list -- but since they already shipped a version; gutting the sound system may not be something worth while that they would consider until a later major version.Although who knows, maybe they would -- and since it is Open Source, and you can submit patches; if you actually got J2 running great on Meego, that would make the process a whole lot easier for them to decide to switch.

Right, this is certainly not the appropriate medium for this kind of discussion, but still I had the give my argument to stand up for those who support and follow open source with concept operating systems and platforms before it reaches the polish of the competitors, in sack of open development process. What Nokia does and has done with Maemo and MeeGo is yet unprecedented from a commercial market point of view. Let me assure you that if you communicate your issues you will get a serious response and if you're right with your complaints action will be taken.
