Re: Another victim of the ebay scam 4GB 4G Touch Screen 2.8'
 

Rennie45, I'm afraid that I don't know what the maximum image size for pictures is on Rockchip 2608A based players but a safe thing to do to try is to resize them to 320X240 (QVGA size).

It is possible that you have an OEM unbranded version of the Onda VX858/VX858LE. Can you post a pic of the box that the player came in?
It could, of course be a clone.

As DaremoS mentioned, VIDROP is great for videos for your player.

Hi - first posting on this (very informative) site !
I too got one of these 8Gb touch screen units and had the same problems. Its a nice little unit but the manual is garbage. Mine came with Xilisoft 3GP Video Converter 3 which seems a good application, but you need to set the parameters up - after a lot of fiddling I found these worked
XViD codec
Summary:
Bit rate: 341kbps
Video:
Format: mpeg4
Size: 320x240
Frame rate: 24.00fps
Audio:
Format: mp2
Bit rate: 64kbps
Sample rate: 44100Hz
Channels: Stereo

You may need to tweak them a bit. I am going to try the ViDrop app next !

Re: Another victim of the ebay scam 4GB 4G Touch Screen 2.8'
 

In your parameters one parameter can be optimized for more enjoyment not affecting performance... audio you can put a higher value try 192 ... or even higher... 256. Always being MP2 which is the trick of Rockchip players.

Video bitrate can also be higher if you aren't satisfied with image... up to 600.

And of course using xvid which is another trick of Rockchip players.

The rest is as it should.

Yeah, the viDrop and AVI Converter seem to be working fine now.
David, I have a pic of the box but I can't find out how to upload it here, seems you have to have it on another website.

Hi rennie45,

You can upload pictures/images in our [Gallery/Photos] section (link on the left hand side menu bar).

Or you should be able to attach images to forum post as well. When you create a post, you should see an [Add Attachment] button.

Hope that helps.

For Rockchip players you have to set the size to EXACTLY the native resolution of the display (e.g. 320x240) If the movie is widescreen, then it has to be padded out top and bottom so it's 320x240 no matter what the picture size actually is.

They will tolerate several framerates, but they have to be integer. You can't do 23.98, f'rinstance.

viDrop is the answer for doing the converting. Don't even bother with anything else.

I use 15 fps and about 90 kbit/s 2-Pass for the video and 48 kbit/s for the audio. Works fine and the movie is only ~100 MB. Very important to tick the 2 Pass box. The picture is just slightly artifacty but, hey, this isn't Home Cinema. I'd rather have 30-odd movies to choose from, which I do, as well as hundreds of audio tracks. I use MP2 at 64kb/s which sound just fine to me. The only thing I wish for is longer battery life.

Thanks for your nice effort compiling instructions for Rockchip players... I feel that you have just some confusion with sound codecs used for your conversions:

1- How do you set WMA in viDrop ... I wouldn't be able to find this codec in my last version of viDrop (0.56.2).

2- How do you make Rockchip player work with WMA when the only limitation for rockchip players is to have sound in MP2?

Maybe you are using the new version of Rockchip players RK2706... and this version allows WMA?

I never said I was using wma in Rockchip. I use it for Pocket PC. I use WMA2WAV to rewrite the wma headers so VirtualDub gets fooled into thinking the wma is a wav. I do this to get really tiny movies when size is more important than quality. I play them on TCPMP.

Oops, I looked back at my post and saw that I did say WMA when I meant MP2. Sorry about that. I've corrected it.

I'm sorry if I confused anybody into thinking I was using wma in viDrop.

Yes this RK2706 handles lots of formats and many of them without conversion.

AVI: without conversion between certain limits (no idea which limits)
FLV, RMVB, ASF, 3GP, MPG
