China MP4 player

    It is 2.4" @ 320x 240 screen
    Radio
    MP3
    eBook
    Tetris
    2G internal + Mini SD slot
    Jpeg viewer (auto rotate and scale to fit)

    All about 82 Euro inc courier from China. Stainless steel case, Lithium battery recharges from USB. Also a charger.

    Built in minispeaker. Some places advertise it as OLED, but having taken it apart (!) I would say LED (possibly OLED) edge light to backlight a TFT-LCD with excellent viewing angle, contrast and brightness.

    supplied demo.avi plays perfect.

    But the mencoder supplied tool creates OK AVI on windows (20 or 24 fps Xvid up 150kbps to 600kbps and MP2 Audio, NOT MP3).

    However sound is badly ahead of video and gets worse.

    Examination of supplied file reveals
    24fps 320x 240 @596kbps
    VBR MP2 @96kbps (However 256kbps MP2 does play, but gets ahead of video)

    4096 bit or 50ms (depending on tool) interleave Audio, NOT more normal 1:1 video frame interleave.

    I can either make video frame interleved AVI, 500ms interleave (=40960bit??) or 42ms Interleave. I can't make MP2 /Xvid mux /interleave that matchs the demo.avi file (which is perfect on player or windows)

    Any suggestions? My source is obviously my personal collection of MPEG2 + AC3 25fps encoded videos @ 720 x576

    Seems to make no difference of lavc or toolame is used for MP2 with mencoder.

    Intermediate AVI's doesn't help either.

    If it didn't do video at all I'd be happy. (still good value). Or if there was no working video. But the demo.avi is stunning and perfect sync.

    This is not one of the older S1 MP4 china players that does AMV or MTV (not real video actually) it uses "Rockchip" engine.

    It plays ANY frame rate other than 20fps or 24fps really really slowly. But audio correctly. If the audio is not MP2 and video not actual XVid codec with H.263 at actually 320x240 exactly it does not play at all.


    I'm open to suggestions.
