Welcome to the Rockbox Technical Forums!
Why should we tailor the hardware for video? just because everyone is doing that? why should we go to touchscreen? just because everyone is dong that?I would prefer to pay for an hardware dedicated to audio than a media player, but thats me
Add a decent screen, and the CPU you have chosen is perfectly capable of decoding video, that, and here is the crucial bit, will only affect battery life if you play video.
Hi Guys, Right now I'm getting parts lined up. I have several devices to take apart, and by the way this is a project with my 13 year old son. Modules are the projects I'm working on now for this. Donated is 900mhz wireless phone with ID caller, dvd player with divx and mp3, and a calculator. This prototype is going to be huge, since there isn't any specified breadboards. Then, any deviations will be in a engineering change. Which mp4 format do you all want? I want to use modules because of trouble shooting. It will be easier to test them seperate, after they are built. I was talking to my son and thinks it would be great to have a solar charger for the batteries.
The DJ tools include a Line out Crossfader, a Headphones Crossfader, Bend, Pitch, DJ Pause, Cue, Loop, EQ, Filter, Sound FX, Headphone Jack, Line out jack and a USB 2.0 connector."
I would like to compare this situation with digital photographic machines and digital video machines. I have and prefer, a specialized photographic machine and a specialized video recording machine. I could buy just one machine to have the both functions, photos and video, however, It will not had nor a good photographic characteristics and a video recording characteristics. What is more attractive? Whats sells better? - probably just one machine with both functions, however, professional prefers specialized machines for each function.
So your pointQuote from: casainho on April 02, 2008, 05:51:43 PMI would like to compare this situation with digital photographic machines and digital video machines. I have and prefer, a specialized photographic machine and a specialized video recording machine.

What is more attractive? Whats sells better? - probably just one machine with both functions, however, professional prefers specialized machines for each function.somewhat doesn't count.
I am afraid of a descharacterized device, that is nor a good hardware audio player nor a good hardware video player.
Why doesn't count? - can you say why do you think that Pacemaker, don't have video capabilities?
To support these features you need a very powerful SoC (i guess even a bit more than the one you've chosen) and a large enough LCD to keep the UI intuitive (for use in rockbox since i doubt anyone wants those buttons and pads (they're even protected by a patent);-)). [...]So i kinda think it's unavoidable that a videoplayer gets thrown on the device with more codecs than "just" mpeg1/2. :-P
My point is, that's very much doable to combine video playback (including a decent color screen) with good auto quality.
The SoC is cheap, the display to and the battery either. So i really don't understand why that is an issue for you.
Have you heard of the Sansa Fuze? No advertisement, but it's said to have a great sound quality. And it features video playback as well as a low price.Just because really good audio players with video playback are rare (depends on how you define good audio playback of course) and sometimes rather expensive, it doesn't mean it's impossible.My point is, that's very much doable to combine video playback (including a decent color screen) with good auto quality.
Putting in a larger, better screen is not going to degrade the audio somehow and neither is using a larger battery. In fact, using a larger screen could potentially make the audio better as you will have more room on the boards to do what you wish.
Also, using price as a reason is also not concrete, as if you do these things, you will have more people who will want to purchase the device. The more people who want to purchase the device, the less the manufacturing/parts cost will be.
I see that you want a blinking led from a ATMEGA32. I don't have linux running right now, video card problems. I do have dos with a parallel programmer, if i could use linus sysem I would use a usb isp. I could use a attiny 2313, if that would help?
So, I am not so optimistic about video not interfering with audio.

So, as you say, using a larger screen means to have a larger player, and thats not what is pretended - It's pretended a small physical size - pocketability.
A 220x176 screen with decent color is not going to ruin "pocketability" in any way. Neither is a 240x320 screen honestly, but it can for some. I am not saying you have to do anything. I am just saying that the reasons you have been using do *not* make sense.Also, I do not see "everyone" wanting a touch screen. I see someone mentioning that this other company happens to have them too. Read what people are saying, as to say something like that is proving that you are not even listening to them when this is *not* what they are asking for.
QuoteSo, I am not so optimistic about video not interfering with audio.Why not?And please do not "cherrypick" (this means that you only respond to the parts of my post that may fit your story instead of responding to everything that I say) my posts. I say things for a reason and to ignore that is not very demonstrative of your willingness to discuss issues.
the irivers are still the daps with the best audio quality supported by rockbox and they're also pretty old by now. However in Berlin at the Alexander Platz in Kaufhof you can still get some (H10 and H300 or H100 iirc) and the "cheapest" one is still above 150EUR (refurbished!).So if you are really making such a high quality audio player it is going to be pretty expensive anyway. A larger LCD and a better battery won't increase the price by that much then anymore.
A said everyone because I see that tendency on new players and because Christian wrote: "We are selling many touchscreen,because many people want it".
About the screen size, ok, 240x320 can be "pocketability" but quickly the size will increment, If you are seeking portable video.
Sorry about that "cherrypick", I didn't know that concept. I just didn't answer/comment because I had nothing to say, I generally agree with what you wrote.
I would like to say that I am not so optimistic about seeking hardware for ALSO video not interfering with seeking hardware just for hight quality audio player. And I mean also the disposition of the buttons, size, price.
Another thing, I did ask to developers the minimum size of SDRAM and Flash memory the player should have to run Rockbox, and I get 4MB of each memory - again, for audio player. If we want larger screen and video, I think that this memories should be 4 or 8 times more. Are this change is sizes expressive in price? maybe not...
And I did not wrote well my idea. I would like to say that I am not so optimistic about seeking hardware for ALSO video not interfering with seeking hardware just for hight quality audio player. And I mean also the disposition of the buttons, size, price.
Thats what I am afraid, new players not focused in good audio quality, instead going to focus more on video.
QuoteI would like to say that I am not so optimistic about seeking hardware for ALSO video not interfering with seeking hardware just for hight quality audio player. And I mean also the disposition of the buttons, size, price.You don't have to. This is what we have been saying up to this point. We want a device whose main focus is audio, but to add a better screen is not going to deviate form that purpose and we are still not seeking hardware for video, as if we did, we would of course want an even larger screen!
Like I have said before, this is not just for video. 4MB very well is around the "minimum". However, memory is cheap these days and if we put a bit more, I think that the cost difference will be very small, and that the increase in battery life from a larger buffer (as well as making things a bit easier on you when porting Rockbox as you have more RAM to work with and won't have to worry about squeezing everything in as much) would certainly be well worth it.

That is more than plenty for video audio and games. 32MB would even be enough for all that (see 5G iPods)
Quote from: casainho on April 02, 2008, 07:58:15 PMThats what I am afraid, new players not focused in good audio quality, instead going to focus more on video.THAT was NOT the point i made. The point i made is that the player like you are proposing it IS already expensive! If you add a larger screen and better battery it's not going to make a real difference. What is 300EUR compared to 320EUR? Almost nothing and i would be more then willing to pay these 20EUR for a larger screen and better battery life.
I was going though the getting started and found that the requirements may need to be used, exspecially the isp and software and didn't find linux operating system. The example in there is to light up 2 leds.
