Video encoding options for Zicplay Zicone Mp4 player

Hi,

I'm trying to encode music videos in a way I can watch them on my Zicplay Zicone Mp4 player. This player seem to have a Rockchip RKNano chipset and is said to support mpeg4 videos. The sample video that came with it seem to have been encoded with xvid and has a resolution of 160x128@15fps. Audio seems to be mp2. However, when I encode a video with mencoder it will play but with video only sporadically showing and playing way to fast.

Does someone know if some special options are required? I'd prefer not to use the Windows utility that came with it.

Thanks

After some trial and error, I found that keyframe interval must be set to one.

Here a command that is working for me (fps, audio and video bitrate can be set higher or lower if needed):

Code:

mencoder Infile.avi -ofps 25 -vf-add scale=160:128 -vf-add expand=160:128:-1:-1:1 -srate 44100 -ovc xvid -xvidencopts bitrate=480:max_bframes=4:quant_type=h263:me_quality=6:max_key_interval=1 -oac lavc -lavcopts acodec=mp2:abitrate=192 -o Outfile.avi

Thanks for posting this. I have an MP4 player sold here in the Netherlands by Aldi (as part of a "DJ Headset and MP4 player package". This also uses an RKNano chip, and your suggestion for mencoder produces a working video.

There was no example working video with the player, so I've tried quite a few options before this.
