cannot play videos on mp4 Rockchip player
 

i bought a 4GB 2.2 in. mp4 player in Taiwan. I tried using the drivers and software which came with the player but none of them works. the sample works perfectly and has great sound quality. The video should be 320 x 240, but I still cannot play it after it is converted to that format. Can anyone help?

Danny, could you list the rest of the specs for the sample? In VLC I find them under information. Of particular note should be the type of audio and video codec, and the bitrates.

You may need to change the audio from mp3 to mp2, or you may need to change the video codec.

Also, my rockchip player came with an AMV converter. Not so helpful when you need AVI files, so check that as well ;-)

Hi,

I can confirm that Xilisoft's "DVD to MP4 converter" works perfectly with both 220(224)x176 and 320x240 Rockchip MP4 players. I purchased this over the weekend and it's worth every $.
I was also able to succeed with the 'free-issue' AviConverter which came with each player once I worked out that I need to manually put .avi at the end of your filenames , but I REALLY like the flexibility that the Xilisoft software gives you.
For example, instead of coding each of the 4 or 5 VOB files individually one after the other (as with AviConverter), the Xilisoft DVD to MP4 software does it all in one go, straight from analysing the IFO's. It can convert straight from DVD - and it appears to work straight from an original DVD ( Region 2 - I cannot confirm this for other regions).

I know I am repeating what others have written above, but to confirm what has worked for me, I use the following settings:

For the 2" player (224x176) :

First, select 'XviD' as the Profile.
For Video Size, manually type "224x176" - on my version (4.0.83 build 0178) this size doesn't appear in the drop-down, but manually typing it as I have shown here, works.
Bit Rate - I have found that 512 works 100%.
Frame Rate - at 20FPS, the sound and video remain in sync. Higher FPS ratings result in a slightly smoother video, but the sound lags behind.
Aspect - Auto
Same Quality - False
Audio Codec - MP2 - Important Note! Although Rockchip players handle MP3 Music fantastically, the video audio must be encoded as MP2 it seems. Xilisost are one of the only ppl who seem to realise this!!
Bit Rate - 128 works for me everytime.
Sample Rate - 44100 - ditto!
Channels - Stereo
Disable Audio - False

For the 2.4" Rockchip players, do exactly as above, but select a video size of "320x240"

The link for the software is http://www.xilisoft.com/dvd-to-mp4-suite.html - What's great, is you can download a free trial version which seems to do everything other than it limits your converting to 5 minutes per file. It's well worth trying this out before parting with your $$$, but for me, it has worked very well indeed.

Good luck, and I hope everyone who's been stuck on this now succeeds! Rockchip players are fantastic value - anyone know if there's a 2.4" version with a removal 'cellphone/mobile' battery on the market yet?

Thanks for the information iixorbiusii.

Has anyone also tried PocketDivXEncoder as well? You can download it here: http://www.mympxplayer.org/pocketdiv...-mb-df139.html.

It's a freeware converter.

thanks for quick reply!


sample video specs:
resolution: 220x176
duration: 2:13
bit rate: 64kbps
frame rate: 18fps
data rate: 108 kbps

it is a world of warcraft trailer (not surprising :O)
if i knew how, i could upload it.

i bought the player from a seller with the company DGS. I tried looking up their website and had no luck. I tried all the software recommended, but still no luck. Here are more specs though:

First of all it looks much like an iPod except that the screen is twice as tall and there is no scroll wheel.
the player looks very much like the one in this picture: http://www.mympxplayer.org/image-asp379.html.

on the menu screen, there are nine icons in the following order: Music; Video; FM radio; Photo; Text Reader; Recorder; Memory Navigator; Games; Settings.
it connects via USB
headphone jack uses 2.5mm
also has a mini-SD card adapter behind the OLED screen

thanks

In fact this program you suggest do nicely the job as a front end of Mencoder, but it fails is the most tricky requirement of Rockchip video player as it is convert audio to mp2

What screen size is your player?
In the first post you said "The video should be 320 x 240"
but later posted the "sample video specs:
resolution: 220x176 "

Does the sample video play?

If the sample does play then try using aviconverter and set the resolution to 220x176 not 320x320

Hmm, don't quote me on this, but if your player is like the one you've linked to, then I suspect it might not be a Rockchip player. I could be wrong - what makes you think it is a Rockchip and not an AMV 'Action' type player?? I am curious; it's a nice looking player, but I always thought this type was AMV only.
Cheers. iixorbiusii

I have to agree, I've never seen one of that style that has a rockchip in it, either.

Maybe you could look at the extension on the file that works? I know it sounds like a basic question, but you are our eyes on this one ;-)

The screen size is 2.2 inch, but it says that it can play both 320x240 and 220x176.
i tried using both formats but none worked.
actually im not so sure about the instruction manual. it told me those specs, but actually the sample movie was 176x220, not 220x176(sorry about that).
when i hook it up to my computer for the first time, the new hardware notifications say that it is a Rockchip USB device.
It doesn't look exactly like that picture, like the buttons are the same color as the casing and it also has a speaker on the back panel.

The extension of the sample movie that works is Xvid (.avi). anything else that goes on does not work. I tried the AMV converter and those videos don't work either.

Hope this information can be of any help :)

Danny, because your computer recognised it as Rockchip, then perhaps I was wrong!! :oops: Sorry about that!! Anyway, in my experience with Rockchip players, they need the movie to be in exactly the right format, with not even one pixel extra on the "X x Y" settings for the movie size. If your demo movie is 176x220, then perhaps try and encode a movie at that size. I cannot remember if Aviconverter gives that size as an option, but I have found Xilisofts DVD to MP4 converter to work perfectly. It's quite pricey, but you can download a demo version which should let you test things out, and I know you'll be able to type "176x220" in the Video Size option.
Please see my post above for details on using their software.
Cheers. iixorbiusii

thanks iixorbiusii
:)

sorry to tell you guys, but it still doesn't work :(

Re: cannot play videos on mp4 Rockchip player
 

Danny144,
some points here for you:
1. If you screen is 2.2 then you can't play 320x240, it must be 224x176 or 176x220...
2. You say that your videos are 176x220 then your screen handles videos turned 270°... have no sense to convert a video to 176x220 WITHOUT turning it -90° or 270° whatever option.
3. To solve your problem you have to use a special version of AVIconverter here; AVIConverter turned
I think this will work fine for you.
No other converter turns -90° and handles mp2, only this one.
greetz

Danny144...
I repeat... this is a special version of AVIconverter looks like the normal one, but it's not... was modded to turn videos.
This version solves the problems of mthuey in thread http://www.mympxplayer.org/solved-fi...il-vt6444.html
good luck

WOW thanks guys it works perfectly!!!
Thanks a lot DaremoS!!!

Re: cannot play videos on mp4 Rockchip player
 

:wink:

Hiya!
I have a nearly identical "mp4" player as this
http://www.mympxplayer.org/album_sho...php?pic_id=387
except mine's unbranded.
I have a problem converting videos to avi because I don't know its resolution. I had a sample video, an Ice Age 2 clip but I've erased it already.
The screen's dimensions are: 1.5" by 1.25".
Below the screen, where the pic displays MF-M568, Digital MP4 Player 945 is written.
My menu looks like the pic's but mine are arranged in 3 rows and 3 columns. please help me, anyone!

Hi Death,
One of my Rockchip's is nearly identical, and it's screen resolution is 224x176.
Please see my comments regarding the use of the xilisoft converter demo within this thread, or the other other solutions on offer from others here.
Cheers!

Danny144,

Out of topic... is your machine like this one?
This is a 2.4 rockchip machine that looks like the usual nano clone just turned 90°, also sport a slot Mini SD



[img=left:54eedb2ad1]http://www.zimaelectronics.com/images/productos/zm624_grande.jpg[/img:54eedb2ad1]

DaremoS, I have exactly that one but in black. It's a great unit (anyone else want to comment?) and has the usual 320x240 Rockchip :lol: menus - i.e. with tabs across the bottom of the screen. I'll post a review of my one soon.

nope it doesnt look like mine
mine looks almost exactly like a nano
except that it is longer.

hello, I don't own a rockchip based player, but I would like to support them in my converter. I understand there are 2 different chips, one being capable of 320x240 and the other 220x176. For which model has the video to be rotated and in which direction ? What about 224x176, is that a 3rd version of the chip ?

Bobby
as far as i understand the 220x176 sized screen is actually a misnomer - when converting files for this size you need to set a size of 224x176 (they are the same) and also a max of 20fps on this size - i have got 25fps on 320*240
if you need to see a set up file then download AviConverter form this site and look at the ini file, some setting are in there

BobbyQ,
I agree with makd511 - I have both 320x240 and '220'x176 Rockchips ... and I say '220' with caution as 224x176 is what works when I use anything other than Aviconverter !! I will have to dig out the 'French Maiden' video which came with the smaller Rocker and advise the size.

I have to say, I tried your Batman conveter for the first time yesterday for my Meizu M6, and it has produced the clearest, sharpest and smoothest movie out of all the software I have tried with the M6 ! Well done indeed! I still prefer the less jerky movies I get with my Rockchip unts, but you've restored my faith in the M6.

I hope you can get Batman to work with Rockchip devices, and don't hesitate to PM me if you need any testing done - I have both sizes (but not a 'rotated' 176x22(4) player yet.

iixorbiusii...

Would you share with me the parameters did you use with Batman for M6?

I've bought a M6 to enjoy all the skinning options... now i want to try Batman instead of Meizu converter.

AFAIK batman works with Rockchip players as it support mp2.. is that so BobbyQ ?

Thanks in advance :)

yes, that's the goal. mp2 and everything else needed is already in the latest beta version, but it is all still under heavy development.
I am gonna reduce the fps of 224x176 version to 20 today. jp could play 24 fps with his 320x240 chip, so I thought that would match with the other chip too.
EDIT : you can download the new beta, the change is in. Looking forward to your feedbacks.

Re: cannot play videos on mp4 Rockchip player
 

I have a Rockchip MP4 player with 2.4" screen. I download videos from the net in FLV format. To play them on the player I use FFMPEG , which is a free command line AV convertor. I convert the Flash Video into AVI. The thing to remember is that for 2.4" screens the resolution must be 320x240 , the video frame rate must be 20 fps and sound must be in MP2 format. All these parameters may be specified in FFMPEG.
Example: FFMPEG -i flash.FLV -vcodec xvid -s 320x240 -r 20 - b 512 -acodec mp2 -ar 44100 newfile.AVI The important thing here is that the resultant file must be AVI with the xvid codec - unfortunately I cannot get FFMPEG to do this correctly (although it supports it) - therefore I repeat the process using avconvertor 3.1 to compress the newfile into xvid. In windows, Right click & summary tab on the resultant file to see its properties to check all the parameters are correctly set (MUST have video compression of: xvid) . If in doubt, look at the sample video's attributes. Why don't I just use avconvertor? I tried that and the conversions all failed or I got format errors when playing them. Aswell as NOT supporting FLV files, it seems avconvertor 3.1 gets upset if it has to perform too many file attribute changes, if FFMPEG does most of them prior, its fine. PS- when using avconvertor, make sure the resultant file is in the same folder as the input file, its quicker!

Under Linux
 

If you are under linux, you can use this:

http://www.sprocketandlube.com/shownews/item/67

I used:

mencoder -noodml input.avi -of avi -o /media/disk/OUTPUT_VID.avi -ofps 15 -vf-add scale=320:-2,expand=320:240 -srate 44100 -ovc xvid -xvidencopts bitrate=400:max_bframes=0:quant_type=h263 -oac lavc -lavcopts acodec=mp2:abitrate=96

My chip is:
ATTRS{vendor}=="RockChip"
ATTRS{vendor}=="0x10de"
ATTRS{subsystem_vendor}=="0x1849"

I can't believe how many "experts" there are who claim to have the answer to making videos to play on these Rockchip players. Especially the ones urging you to use xillisoft crap converters. Don't give those scumbags any money.

Just use viDrop. End of story.

And why are so many using 400-500 kbit for the video? You can't see that much quality on 2" screen, so why make your movies so huge? I use around 100kbit 2-pass and it looks perfect. Filesize a bit more than 100 megs. And I use MP2 audio at 48 kbit, even tho it supposedly isn't supported, it works and it sounds just fine.

And, BobbyQ: Don't waste your time. viDrop is already here.

-freddy

Are you some sort of "expert" too... I've read in other post by you that you use WMA for audio... how do you set WMA in viDrop Freddy???

I don't use wma for Rockchip. That's for Pocket PC. I use WMA2WAV to fool VirtualDub into thinking the wma is wav. This is to get really tiny movies, as small as 50 MB for 90 min film. These play fine in TCPMP.

I see the trouble; I apologise. I said WMA when I meant MP2. I've fixed that. Sorry, I didn't mean to confuse anybody. viDrop does NOT have wma.
