MT1389xx Based Player Information

[monty0815]

Haven`t dared to update my gran prix player yet (and probably won`t after what i`ve heard).
I just tried some sort of basic cooling with some heat paste and a small heatsink.
Still that didn`t solve the problems with the speed/slow downs.
Has anybody had any luck with any modification to the player?

Happy new year,
cheers, monty

[CruNcher]

jep i also wouldn't risk it for now at least try updateing my replaced MD 7457 again :)

[monty0815]

Too bad, seems most updates fail.
With my basic spanish I understood that most nevir Players which had their official update are dead now.

What players with Mediatek 1389 is there out there now?

[SHODANXX]

I own the Medion Player too. But i got problems encoding my DivX/XviD.
While Video always works the player does not play the sound.
I use Lame as MP3 Encoder trying different bitrates but it did not work. Which Bitrate do i have to use?
And to the question mentioned above: the player is able to play several encoded avis from DVD. as well as it plays jpgs, mpgs and mp3s from DVD+-R(W).

It would be nice to think that MediaTek would know, as I think it's a great shame that chipset manufacturers in general don't have greater control over second party firmware upgrades designed for use with their own manufactured chipsets!

what about reading the first post in this thread!

[SHODANXX]

Uh. I am sorry. Think i violated one of the most basic forum rules.
Please accept my apologies.

[m99]

Oops! I didn't notice that the first post was updated.

[oddball]

The RIMAX player has a Mediatek chipset. If you hex edit firmware 'A' MTK.BIN on their site it has "MT1369 RESETDISC UPGRADE". Can someone find out if that is inside the bin file for the 1389? or if there is a difference between the two chipsets? I read somewhere that the Ascomtech firmware could be used on the RIMAX also.

[Divido77]

Hi everyone! I´m from Spain and I have the dvd-mediatek Nevir 2046 and I update with the own firmware and now is perfect! no desincronizations but no yet capable for ogm in xvid but it eat most part of my divx and xvids and with high quality.I know that the grand prix and medion 7457 are suitables for the same firmware so if you are with security of return the dvd you can try,I know because in the forum in Spain the people now are not getting in trouble with the firmware for Nevir,in the beginning it was a problem cause a lot of dvds died but now with the sistem for burning(very important switch off before updating) they are living and going very well.And the Ascomtec 3004 is suitable for Elta 8883.The problem is that firmware for ascomtec is not very functional,it doesn´t repair the problems at all.
sorry for my english,I left my classes years ago and now is very poor...
Cheers

[CruNcher]

(very important switch off before updating)

hmm what do you mean by that what to switch off ? the Power ?

[DMJ]

I got myself a Medion 7457 just before Christmas :rolleyes:
And want to hear if anyone knows if it supports *srt subtitles (or any other subtitle format)
And if so, how to use?

DMJ.

[Divido77]

Hi,when I said switch off it was the power efectively,cause in the volatil memory stays some dates from the disc read before,switching off its cleared completly the memory and then is ready for the firmware.Think about it,with the file of the update, that we are changing all the firmware initial,1Mb most part of times and any date that is remaining can avoid the good working of the dvd.

[monty0815]

@DMJ subs aren't supported at the moment, an i doubt there will be a firmwareupgrade in the near future

@Divido77
Could you please give a link to the flashing instructions, as I find it kind of hard to navigate through the spanish forums

cheers

[die_leuchte]

Hi folks!

Be cautious with the fw from the nevir player. 4 of 5 people who tried to flash the Nevir firmware on the Medion 7457 destroyed their players with it! Seems like there different versions of the Medion 7457 on the market, so better wait for official updates. If you want to know more and you're able to read German try http://www.dvdboard.de/forum/showthread.php?s=&threadid=64372

pls. read the complete thread. If you have problems with understanding ask me for a translation.

[CruNcher]

what die_Leuchte wrote is true at least for the Medion their 2 different
mainboard assemblys and we don't know yet how this interfers with the flashing process so still be carefull and even with the switch off power method (and if i remember correct i done this) it could be the last CD that your drive is gonna read :(. New findings also show that some CBR MP3 are not standard conformly done but it's nearly impossible to say what the problem is it could be a old "b0rked" Lame version that produced floating point CBR encodes so you can be almost sure that videos that are old "downloaded/selfmade" that play fine on the PC could have problems with sync on the Standalone, but it's not MediaTek's fault their new firmware solves it wich is indeed a nice feature.

Ahh and here is something funny :)

this is a new MediaTek Based Player from (France) the Peekton 6003

[die_leuchte]

Ok cause this is one thing realy pissing me off, I set the whole night in front of my MD 7457 to find out in which constellation the assynch problem occures and thats what I found out (maybe someone could tell me what that means):

(Used Gspot to compare the different files)

Divx with MP3 CBR 128k "Split = Yes" OpenDML Avi -> asynchronous
Divx with MP3 CBR 192k "Split = Yes" Avi -> synchronous
Divx with MP3 CBR 64k Mono "Split = Yes" Avi -> synchronous
Divx with MP3 CBR 128k "Split = No" -> synchronous
S-MPEG 4 v3 with MP3 128k "Split = Yes" -> synchronous
Divx with MP3 CBR 96k "Split = Yes" Avi -> synchronous
Divx with MP3 CBR 96k "Split = Yes" OpenDML Avi -> asynchronous

seems like the async problem only occures when "Split = Yes" and the file is OpenDML Avi.

It'd be great if there'd be anyone out there that could tell me what Gspot means with "Split = Yes" and OpenDML Avi & Avi (in the Stream Type and A/V interlace section).

I did not find accurate information about over 2gb files for elta 8883, does it work?

I assume that the firmware (not the Mediatek chip) determines if the over 2gb file in udf format in DVD-R can be played, right?

I have an opportunity to buy the new Rimax player with Mediatek chipset (the better one?). But I did not find any info about it's ability to play over 2gb files. Also I did not find any info about it's new firmware or the ability to playback the subtitles (simple .srt etc.). Does anyone here know something bout the Rimax new player?

No. It stops playing after something around 1GB.
But it does play files <2GB fine.
AFAIK theres no player out that can play avi files >2GB, if you can find one please post, im also searching.

[Top_Cat]

How can I tell if my Elta 8883 has a GE Chip or a DE chip? I just ordered one from ebay so it would be good to find out when it arrives

Thanks

[bond]

open the player and look what is written on the chip ;)

[amango]

An update for GE-based chipsets will be available soon. Medion just announced an update for the MD-7457. It should be released in two weeks. Also Nevir announced an update.

[CruNcher]

@Top_Cat all Elta 8883 have the DE Chip

I don't quite follow. You must mean "It stops after something around 2GB" (Instead of 1GB??).

I find this odd. In the Kiss forums, there is some info about the UDF support. And I can play over 2 GB files using Sigma's Xcard (with UDF filesystem on DVD-R). And the xcard uses similar chip to the Kiss (of course the drivers and firmware must support over 2 GB). The 2.0 beta drivers did bring the support for over 2 GB files, so I assume the firmware must support it too. I must check in the Kiss forums, if the player can handle over 2 GB.

Is this the actual truth, there must be someone else requesting for firmware update (for standalone players) to support over 2 GB, hmmm?
Can anyone else confirm, that these Mediatek xx chip equipped players can't do over 2 GB ?? Well I guess that if Zhnujm says so, so it is, sad. :(

In the bottom line, I might just get the same quality using Qpel and multiple b-frames with 2 gb file than I'm getting now without Qpel and b-frames using 2.4 GB file. Thanks to Xvid team. :)

** EDIT **: for Zhnujm: here is thread from Kiss forums. Few persons calim that they can play over 2GB AVI. Generally the opininon is that it is not possible. So only way to find out is to buy the player ;)

[Doom9]

Some rather disturbing news regarding the GE chip: I asked DXn about that chip, and they haven't had any in their lab and so far have been unable to get any information about the chip from MediaTek. I'll keep you posted on any development on this issue.

[Top_Cat]

CruNcher: Thank you for the information. Is it worth updating the firmware on the 8883 I get the feeling that some people are having problems with it?

[Zhnujm]

@begu:
No, thats the funny thing, if the file is bigger than 2GB (i tried a near 4GB file) the playback stops much before the 2GB limit.
Cant say if it is exactly 1GB, but the same is true for my Yamada (ESS based).

I think the kiss players are a bit expensive only for testing ;), but before that, the Sigma Players were limited because they did not support UDF DVDs so maybe its now possible to play >2GB files with the UDF support.

And i would also ask at least twice if somebody says that a player can play files >2GB, most people make only a short test if the file is playable and nothing more :rolleyes:

But i think i can live with splitting the files in 2 or 3 parts until theres a player that supports it (and does not use Sigma or ESS).
If that ever happens ;)

[begu]

Odd indeed :/
Well if I calculte correctly:
2 GB = 1024 * 2 = 2048 MB -> You can encode ~2040 MB AVI ?
And this can be played back without problems.

The only positive side is, that with the advanced options (b-frames and Qpel) I may achieve same quality with 2gb limit than using bigger files without advanced options.

So, maybe the FW will be updated to support >2gb someday.

[Doom9]

alright, the GE chip mystery is solved but I'm afraid the news isn't too good:

The 1389GE is an early version of the certified chip. It is incomplete and buggy and was to be sold as a generic MPEG-4 chipset without DivX playback (and thus certification).

DXn is currently testing the chip but it appears to be identical to a chip they've tested before and that failed certification. So we can remove the DivX certified from that chip..

[bond]

normally i would say "who needs divx certification" but when it didnt even pass this outdated/limited certification its surely a little risk to use that chip :D

tough it would be interesting to know what exactly were the reasons why it didnt pass

[SeeMoreDigital]

Agreed!

It must be a pretty poor chipset.

Cheers

[CruNcher]

hehe finaly that is solved i knew it before because that thing is swapping the markets @ very low prices but the only problem with that chip that i expirenced so far is a speedup/slowdown problem :) but you can save like 40 € for such a GE player and its virtualy the same from the feature set.

@Top_Cat some sync isues are solved with bad encded MP3s and scaleing is done better, also srt subbtitles are supported and some other things watch the changelog on elta.de

thx Doom9 for clearing this hope MediaTek isn't mad now ;)

Doom9 could we get information on wich tests in the Certification process it failed ?

[monty0815]

Can anybody confirm, that the Elta Players don`t have those Speedup/slowdown problems, because I can remember somebody saying that he has been experiencing those on his Elta8883?

Btw I tried modding my Gran Prix with a cooler, but didn`t help against those Problems, eventhough I thought it helped at first, but then yesterday I was proven wrong 3 times during a movie.

cheers, monty

The elta 8883 does NOT support subtitles. :(

@monty0815:
I dont have problems with slowdown/speedup with the elta but i think that means nothing, maybe my files are different.
Best thing would be if somebody can upload a file that has this problems for sure so somebody can try it with the elta.

[CruNcher]

Zhnujm if it would be that easy the problem we talking about happens randomly never @ the same place and if some people say it does they are wrong this problem is a technical problem also it hasn't anything todo with the CD thats being used it's just happening after some time. I tried for example allways with my Equilibrium Encode and it happened the 2nd time at another place then at the 1st and also sometimes you can watch a whole movie without it but other times not i mean i accept it as it is for 40 € less ;) but if it would happen more often i would definatly buy a DE based Player :P, thats not the case so i can live with it :)

[Doom9]

Doom9 could we get information on wich tests in the Certification process it failed ?
I very much doubt that. I've had a long discussion about the certification process, a "super" certification (including GMC and QPel) and DXn's bottom line was that they encourage manufacturers to include those features but right not cannot afford to piss off all their OEMs who are incapable of passing such a certification. They'll eventually add new features when tbe next generation of chipsets roll out (hopefully all supporting the entire MPEG-4 ASP featureset), but until then, they encourage independent testers to test for such features and use a scale that reflects the performance of a player not only w.r.t. their certification requirements, but go beyond that. For instance, a player that can only handle 1 CD DivX3 rips flawlessly would not get a very good rating in the DivX3 department.. stuff like that.

I have asked whether they'd actually publish an internal evaluation like that and the answer was a clear no, thus I deduce that they have no interest in pointing out specific flaws / problems in a player / chipset and risk pissing off their partners.

[CruNcher]

i understand thx anyway :)

[plazz2000]

I have two 2MB test clips here that I would like someone with a Mediatek 1389xx player to try out.

Both are 18 second clips encoded with XviD 1.0 Beta 3. Both use QpeL, but one has 1 consecutive B frame, the other has 2.

The video with 2 Bframes is jerky, it's not exactly unwatchable, but you can see that the playback (especially on camera pans and zooms) is not as smooth as the other clip.

I have tried encoding the same clip with 2Bframes using Koepi's old 24/06/03 devapi3 build, and it plays perfect. So the problem is only with the new XviD 1.0 Beta 3, when 2 Bframes are used.

I'm using an elta 8883, with the firmware upgrade.

If anyone would be kind enough to try these out on their player, please PM me. Thanks.

[Zhnujm]

Maybe "packet bitstream" was enabled ?
Its on by default in the new Xvid beta 3, before it was disabled.
And it causes jerkiness on Mediatek based players.

[plazz2000]

Thanks, I didn't know that. I'll encode another test clip soon and try it out.

[DMJ]

To amango !!

Where do you get the info about an upcomming update for the Medion player?

I have been looking at www.medion.de without luck (it might come down to the fact that my german is very very poor)

DMJ.

[die_leuchte]

There's no official statement from Medion at the moment. The info about the upcoming FW update came via e-Mail from Medion's support.

[DMJ]

die_leuchte

Thx for info :)

[begu]

One question about these players. i did try to find some info about interlaced video support for these Mediatek chip players.
But I did not find accurate info.

So if I enable the interlaced encoding option in xvid, will the playback be successful? And when b-frames (1 to 3) are used, how it works then? Anyone..?

[die_leuchte]

@begu:

afaik interlaced is only used when you have an interlaced source, so it must some kind of deinterlacer integratet in the encoding tools of xvid. But there'd be no difference in the result, only some horizontal lines cause of the deinterlacing.

In my tests xvid files with 1-bf played well on the 7457. But Doom9 wrote sth. about 2 & 3 b-frames played choppy on the Grand Prix (which is nearly the same than the 7457).

[Doom9]

In my tests xvid files with 1-bf played well on the 7457. But Doom9 wrote sth. about 2 & 3 b-frames played choppy on the Grand Prix (which is nearly the same than the 7457).That is incorrect. I never tested the gran prix player but if you check this very forum you'll find reports saying multiple b-frames is no problem on MTK players. I tested a sigma based player.

[die_leuchte]

I'm sorry Doom9. thought I read sth. from you about b-frames.

The only thing I had problems with was gmc in xvid files with my Medion.

Interlaced playback works fine on my elta 8883, unlike the other (ESS, Sigma) players.
Maybe you have to change the field order, in divx theres a button for that (top field first), in xvid you need some avisynth tweaking.
bframes >1 also work fine, as long as you have disabled "packed bitstream".

[CruNcher]

die_leuchte hmm their are no stuck problems with the Medion and 2 bf that's only because many people mix to much up and do alot of false reports the problem you are refering too is the packed bitstream problem.
