Mplayer expert!!!
We use mencoder to transcode the videos on our site. very powerful indeed. Scott - 22 Apr 2008
Hi there. This is exactly the info I needed. Thanks! I have a problem. I need the Windows software, which I accidentally deleted (stupidly thinking I didn't need it). Can you tell me where to find a copy?

These instructions work for the Zvue 250 player as well. Excellent! Elton - 15 Jun 2008
Hi Kevin, great to hear there that.
One more bit of info which is relevant to the Rockchip. I noticed that after playing a video for 40min or so, the audio goes out of sync for some reason. I have no idea why this happens, but one solution is to split the video up into half hour chunks.
To do this you need to add the following options to your encoding command
-ss SEC where SEC is the seconds to start from and
-endpos SEC where sec is the endpoint in seconds.
So, to encode the first half hour of a movie add the following...
-ss 0 -endpos 1800
Note that this will only work for movies that have a correct time code. If you have movie files from Mythtv you can copy them without quality loss and restore the index as follows...
mencoder movie.avi -ovc copy -oac copy -o out_movie.avi -forceidx
I hope that helps. Will - 21 Jun 2008
Thanks for this info. I bought my wife one of these players so she can watch movies when she goes in to hospital to have our baby.
I started trying to work out what settings to use with mencoder and gave up and searched google instead.
This is just what I needed. Cheers! JMM - 2 Aug 2008
Hi,
The "64 max_sectors" trick also worked great for my neonumeric nm4 (default was 240 max_sectors).
Thanks Pierre - 23 Aug 2008
Thanks... My video is very good but there is a problem with this audio. Sound is very bad. Do you have any ideal?
Source audio is MP3 at 48000 or 32000.

Hi Pierre,
I once had had a problem very bad audio. It turned out to be a certain version of Mencoder which was stuffing up. If possible, try a different machine and see if you get the same results. Otherwise try install a different version of Mplayer.
Hope that works! Pierre - 24 Aug 2008
Thanks Javawocky!
I was running: MEncoder 2:1.0~rc1-0ubuntu1~gutsy1
I am now running: MEncoder 2:1.0~rc2-0ubuntu1~gutsy1
Sound is good now with this version.

Hi, Guys. I have seen this rockchip mp4 player on ebay, and was just wondering if it is worth buying? Q - 2 Dec 2008
MP4 player on ebay... it's okay still trying to understand how it works...
So... it's FM radio and think of it as an ipod shuffle with an touch screen.
It comes with tetris and it doesn't seem to allow you to add games. Only basic docs. No tech info. Chip maker isn't giving out info.

One other comment. based on the above mencoder options I figured out the 8gb MP4 video encoding. It's
mencoder -noodml INPUT.avi -of avi -o OUTPUT.avi -ofps 22 -vf-add scale=320:-2,expand=320:240 -srate 44100 -ovc xvid -xvidencopts bitrate=400:max_bframes=0:quant_type=s16le -oac lavc -lavcopts acodec=mp2:abitrate=96

Does anyone have info on the Rockchip ? Or the OS on these players? Javaris - 4 Jan 2009
yo how did you get it too work usig wine in ubuntu whats your settings because when i try to convert my videos it stops converting at 9 secs thats how long my video lasts Javawocky - 4 Jan 2009
Hi Javaris,
That is strange, do you have an endpos option set in your encoding string if so - remove it.
Also, I don't use wine, I use mencoder supplied by Ubuntu itself and it works fine. lca77 - 11 Apr 2009
Getting Audio & Video staying in Sync is very easy: the videobitrate has to be a multiple factor of the audiobitrate: if Audiobitrate should be 96, video has to be 192 or 288 or 384 ;-) Tested wit a 60min videofile on an RK2606A- and RK2608A-Player. rgrds from Germany, lca77 Will - 4 Jul 2009
I have a Rockchip digital mp4 player ( RK2606A ) and there's a problem with viewing video files. It should play "avi." files but it doesn't ( file format error ) if I paste some other format it don't even recognize em.. For converting video files I use "AVI Cnverter" somb know that to do plz let me know on triangleus@yahoo.com....!!!
thx!!! palug - 25 Aug 2009
Thank you so much for this! It works perfectly on conversion of mp4 media from youtube vids to an avi useful on the sylvania smpk4068 Otus - 18 Sep 2009
Thanks! The following works well on my 4GB model.

Thanks a Million!! Catcatmu - 25 Dec 2009
I've created a script for batch processing the videos its meant for Linux though and is python based:

And one for those large movies since it is so hard to fast forward!:
