[solved] Videos not working on 2.8" LCD Touch Screen MP4
 

Can anyone please help me figure out what format I need to convert to to get my videos working on this player? I've tried everything and it just keeps screaming that the format is wrong. This is the player I bought 32GB 3.0" TFT Touch Screen MP3 MP4 w/Camera (US Seller) - eBay (item 170483664652 end time May-10-10 03:06:12 PDT) It came with one .avi that works. But none of MY .avi's work with it. I tried reconverting the files to .avi and I still get the format error. It won't play any of my .amv's And the info file says that the player only takes amv's which is totally wrong cause the one avi works. I really need help with what format I need here. I've uploaded the one .avi file that works. Can someone please see what format this is? I don't know how to tell exactly what this is. The .avi is about 18megs to download. Hotfile.com: One click file hosting: Matsuura Aya.rar I have converter programs, I just have no clue what I need to set them at to get my videos to work with this player.

My firmware version number is:
13.00.10.1018.0904

None of the sample videos work. I have no idea why. And I've tried converting with the same settings as the sample video it came with and nothing works. I just can't get it play any of my vids no matter what format I try. There has to be some combo of it to get it to work.

Thanks for any help.

Download these test videos:-

try each one in turn, then the video will display the correct setting to use in viDrop converter.

I tried that twice, it won't play any of them. I analyzed the sample video it comes with that it plays. This is a screenshot of the specs. Can you help me figure out how I can duplicate these specs? I've tried alot of converters and nothing's working. It just keeps saying the format is wrong.

Try the generic Rockchip 320x240 preset in viDrop note the audio must be mp2 not mp3.

None of them work. I tried the low, medium and hi ini files, didn't work at all. I still get the same error, none of them will play.

I'm having no luck. The problem might be something with the weird audio codec they use. Here's a screenshot of the info from Virtual Dub on the sample vid. Look where it says the compression is unknown. I've had that problem with all the converters I've tried. Something is going on with it.

I did a file analysis of the video the unit records and plays back. Here are screenshots of that. It's using a German MP3 audio codec from Fraunhofer.

I need a program that will do an Xvid MPEG4 with the same kind of MP3 audio codec. Any ideas on what might work? If you look at these settings, they are totally different from the sample file. And these are from videos I made with the unit.

I have the same problem as yours and thanks for your file analysis. I used FormatFactory 2.3 software to convert FLV file to MP4. My set up:
video encode=MPEG4(Xvid), video size=320x240, Bitrate(kb/s)=16000, and FPS=20. It is working now.
Just like you said the sample video is not AVI, but it is Xvid, And my MP4 is an ACTION CHIP ATJ2237T.

It's still not working for me. What audio settings did you use, and can you post a screenshot of the FormatFactory settings you used if possible? It would really help. I'm not sure what settings I have wrong.

Looking at your screenshots and comparing the one that works and the one that you created, I noticed the FRAME RATE/fps is DIFFERENT.

The one that works has a FPS of 22
The other ones you posted are 20 and 25 fps.
Try to changing the framte rate to 22 and see what happens.

Let us know.

Changed the framerate, didn't make a difference. I still can't get a working file out of anything. Each time I'm sure I have it matched up right, it doesn't work. It's driving me crazy. I've tried all kinds of audio settings, too. Nothing works. And yet, it's still playing its own recorded videos just fine and the sample. But that's all it will play.

I tried copy and past a screen shot, but the past was not show on quick reply. Anyway, I left audio part as default from FormatFactory and I also set at Low Quality and Size. I also reformated my MP4 memory. I'm not sure that will make a different.

Hope this will help.

I think mine is set for high quality, I'll have to check it. I messed with alot of settings, so I know it's no longer at default. On the audio default, is yours set for mp3 or mp2? I'm unwilling to reformat. I'm just afraid it will kill the thing and they didn't give me any firmware for it or where to find it. I don't want to mess with that right now. To post screenshots here, I uploaded to my own server and then put the url in with the img tags.

I got it working! It had to be re-encoded with the right version of CHN-ENG AviConverter 5.1.6 It won't work without it. So, I have written up a guide on how I got it working and included this version of the converter with it. There is no other way to get it working on my unit without it. This may also work for the new 7 inch netbooks, as well. The manufacturers are claiming they do Xvid, so I'm guessing this is it. You can get my guide here, it's about four pages long, and this is the newer version of the converter.

Thanks for helping me :D

All wasn't totally solved, my 32GB won't let me go past 2.8GB. It's definitely a hack job. I just wanted to add the chip specs to this thread, I think it's a commonly hacked Actions ATJ209X/ACU75XX.

Does anyone know what firmware this takes? Also, is there a way to see the hidden files on this thing? I can't get to it with Vista and I don't want to do anything to kill the player, I just want to view everything on it. One other question, what does happen when you format one of these? Do you lose the firmware or does it just boot back up with it? I didn't get any firmware on a CD or anything with it.

It works, I just want to do alittle exploring and I know it needs a reformat, but I'm not sure I want to go there just yet. I have no clue what the real size of the memory is. But it spits out corrupt files if I try to add anymore. I'm probably lucky I got what I got working on it now.

You are lucky that your memory is 2.8gb because my is only 2gb instead of 32gb. I reformated my memory and I believed the firmware was still intack. After formated, I put musics back in and it played, but the momory still indicated 32gb. I contacted the seller today and hoping for some responses reguarding to hacked memory.

It's possible mine is lower than the 2.8, but somehow, the files are working on it, but I can't add anything. If I try, the files show up as either zero bytes or I get file format error. It's a badly hacked drive.

What they do is, they take memory chips that real factories throw out because they are defective, then they hack them up and make these ipods. So we're not only getting fake GB's, we're getting unstable memory chips.

There is a way to get the hack off, but it doesn't always work because they hack the chip itself. The only true way to fix it and have a stable ipod is to get a real memory chip and replace it. And that's a big pain and would cost too much in time and effort and money. You might as well buy another ipod for all that.

I'm just praying mine will last awhile at this point. It does need reformatting, but I don't like the idea of doing it, especially when I don't have a firmware backup. Then we're talking about formatting an unstable chip to begin with which isn't going to fix the real problem.

I sometimes get the format error after transferring more than about 4 files to my Rockchip 27 32GB
when I delete everything and format the MP4 the same file works OK as long as it is the first file I transfer after format
then the same sort of thing happens to the 5th or 6th file I transfer and every file after that
then I go through the whole thing again format and re-transfer - something is basically wrong

Silclay, how many megs/gb are you putting on it when it explodes? You need to find your limit and then that's really the size of the drive you bought. It's a hack job.

Different each time
sometimes I manage to put 5Gb sometimes more

the drive properties shows about 31GB but I suspect that there's something in the size of the individual files.
I don't know if this is a file size limit or a limited cache in my computer
proplem is I don't know where to start.

Is there such a thing as a defined limit to the size of individual files irrespective of the drive total size?
if so how do I change it?

Sort of. These things are usually in FAT32 format. FAT32 takes less than NTFS. Like when I bought an 8BG flash stick, it wouldn't let me go above 2 or 4GB until I reformatted with NTFS. Now it works great. But the thing is, you can totally trash your player if you reformat with NTFS. I've heard bad things from that. Like your OS might not recognize it anymore if you do that. I would say, research that first.

That makes a lot of sense
If I re-format the drive in NTFS and it is not recognized can I then fix things by re-formating again in FAT32?

Do you have a link to anywhere that discusses re-formating a rockchip 27XX with NTFS?

Thank you so much

I did a little researchand it looks as though doing a NTFS format is a good thing-see
http://mympx.org/forum/support-how/4...4-players.html

But the other part of the lesson is that it all goes back to FAT32 after reset or did I misunderstand

If it just goes back to FAT32 will i have wasted my time? or do I just avoid doing a reset?

Thank you

That's kind of the problem with these players. If you do NTFS, the firmware is what I think gets messed up and then that's why your OS won't recognize it. The firmware is not equipped to deal with NTFS. So then you are forced into going back to FAT32. If you have a backup copy of your firmware, you can give it all a try and see what it does.

Thank you
I can not tell you how grateful I am !!
especially because you were good enough not to make me feel like a total lamer
which is quite rare these days
Thanks again
