Atmel-AVR32 uc3 Video player

[lolypopboy777]

Wow.. And what's that screen? :D

[leemes08]

i would also like to know what encoding u are using...

[pZippi]

@leemes08 It is a self developed Codec. You can send me your Mail adress and i will send you all infomations and the converter.

[leemes08]

@pZippi no thx, just wanted to know "what's possible"... respect for developing an own codec :)

[ahmetttism]

@pZippi hi, could you send email it to me about video codec and application.

[satyricon1787]

wow

[32shirish47]

hello i want to know about the OS...& how u put that on it..i mean we write codes in AVR studios and burn it to micro controller ..have u done it that way ca n get to know circuit u have made???

[tanioklyce]

What is the board you are using? Is it custom?

[smartflyerbrushless]

Blender is the best!!

[rudz0n]

Raise up, if you want "bunny" back!

[element2310]

What format is the video file you're displaying, MPEG1/2 H.264 or something else?

Very nice work BTW.

[qettyz]

@element2310 I think that this is raw video file (= big file), what is just streamed thru SPI to display.

[element2310]

@qettyz yeah i figured it might be a RAW file. Though the AVR does have enough get up and go for MPEG1 and probably H.263 at a push, its a great demo what ever way you look at it.

[monstercameron]

how much for one?

[schalotten]

Would it be possible to implement codecs like Dirac or VP8?

[m23402027]

way too cool bro! is it running on some sort of RTOS or natively written in C?

[chimerahitman]

Could you please tell me about CPU speeds or some additional hardware you used or is it all just avr?

[pZippi]

@chimerahitman

I use only the AVR32 at 66Mhz + Audio DAC (tlv320dac32), for the Video player. But it also works with the internal DAC.

[dedyaaa]

nice...!

[linuxrobotdude]

Is it running Linux? I thought the linux kernel doesn't support the UC3 family.  At least, that what Atmel claims.

[pZippi]

Linux is not running. It is only written in C.

[AdirHaker]

WOW!!!

[luvocean1]

what screen are you using? are you writing SPI or parallel 8080? I have tried parallel 16bits to ILITEK screen and the write is so slow. it seems to me the UC3A1xxx is very slow toggling the GPIOs. I am curious to see how you got it to stream such fast to show 25fps???

[pZippi]

@luvocean1 It is a siemens S65 Display with spi interface.

[jcomega03]

@pZippi

The SPI is fast enough?

How many "memory page" is in your sceen? (I have tried parallel 16bits to ILITEK ILI9325, there are only one memory page (172KB), I can't write in background (hidden) a secondary picture.

Or do you use an external SDRAM?

[pZippi]

@jcomega03

Yes the SPI is fast enough. I need 700k cycles for one refresh. The Display has only one memory page(46kbyte) and the UC3A has 64kbyte internal SRAM. I do not use external RAM.

[odv000]

nice!

do you implement some codec or just raw images?

[pZippi]

This is a self developed codec with a compression of ca. 90%. But it is not ready yet.

[odv000]

what means 90% ?

for example XVID has aprox 100:1 i.e. 100 megabit becomes 1.

[pZippi]

I have 100:10 i.e. 100 megabit becomes 10. But i will try to get 100:(2-4).
