cannot play videos on mp4 Rockchip player

[iixorbiusii]

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 ?

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

[BobbyQ]

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.

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!

If you are under linux, you can use this:

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.
