MP4 player will only see AVIs (not AMV) and won't play

This is driving me nuts.

I bought this MP4 player before Christmas and have yet to been able to play any video except the demo video which was preloaded (8 minutes of Ice Age)

This is what the manufacturers (http://btb.en.alibaba.com/product/50...P4_player.html) claim:

1:2 inches 260,000 colors real colors TFT colored tablet demonstration.
2:Supports MP3, WMA,WAV (only in this machine recording document) the music form,the
real audio frequency frequency spectrum demonstrated, A-B duplicate reads the
function.
3:Supports MPEG-4 (AVI) the video frequency form, entire screen broadcast demonstration,outside
sound speaker broadcast.
4:Support transformation video frequency form:AVI RM RMVB MPG MPEG MP4 ASF WMV MKV DAT VOB and so on..

The player was accompanied by drivers and software including AMV Converter (3.5.02 and 4.07).

Now here's the problem:

The player does not see any type of video files except AVI files. AMV Files when browsed for, are unplayable. So I'm not sure why the AMV converter is included.

OK but I still can't play any AVI files EXCEPT Ice Age.

I have taken the Ice Age AVI and analysed it. This is the mediainfo analysis:

Format : AVI
Format/Info : Audio Video Interleave
Format/Family : RIFF
File size : 35.1 MiB
PlayTime : 8mn 8s
Bit rate : 595 Kbps
StreamSize : 898 KiB
Writing application : MEncoder Sherpya-MinGW-20060312-4.1.0
Writing library : MPlayer

Video #0
Codec : XviD
Codec/Family : MPEG-4
Codec/Info : XviD project
Codec settings/BVOP : No
Codec settings/QPel : No
Codec settings/GMC : 0
Codec settings/Matri : Default
PlayTime : 8mn 8s
Bit rate : 494 Kbps
Width : 224 pixels
Height : 176 pixels
Aspect ratio : 4/3
Frame rate : 20.000 fps
Resolution : 8 bits
Chroma : 4:2:0
Interlacement : Progressive
Bits/(Pixel*Frame) : 0.616
StreamSize : 28.7 MiB

Bit rate : 94 Kbps
Bit rate mode : CBR
Channel(s) : 2 channels

I've then converted files to as close to this criteria as River Past Cleaner can get (for example):

Format : AVI
Format/Info : Audio Video Interleave
Format/Family : RIFF
File size : 2.11 MiB
PlayTime : 1mn 150ms
Bit rate : 287 Kbps

Aspect ratio : 4/3
Frame rate : 20.000 fps
Resolution : 8 bits
Chroma : 4:2:0
Interlacement : Progressive
Bits/(Pixel*Frame) : 0.226
StreamSize : 1.31 MiB
Writing library : XviD0046

Audio #0
Codec : MPEG-1 Audio layer 3
Codec profile : Joint stereo
PlayTime : 1mn 48ms
Bit rate : 96 Kbps
Bit rate mode : CBR

StreamSize : 703 KiB

I realise there are small differences but I have done hundreds of different versions and have altered each one.

Still Nothing.

Ice Age.AVI will play - and nothing else.

Has anybody got any ideas?

I've just spotted this thread RockChip
Which sounds like the same problem. This AVConvertor did not come with my unit. I will try it and see if I can get it to work.

I'll report back....
Cheers!

calforba, As you have found your player is using the Rockchip which is avi compatible.
avionik99, did a conversion guide here:
http://www.mympxplayer.org/how-to-vt3183.html

or you can try one of the AVConverters in the Downloads>Tools section

Ok this solved it:

http://www.uxcell.com/public/mp4/mp038_avconverter.zip

There's no facility to change aspect ratio or anything, I would suggest that if you want to view widescreen you convert to 224x177 avi in a different package that can provide banding and then convert with this.

Cheers

I Have The Same Problem I Have MP4 PLayer i Mean MINI MP4 I Have a DDemo Video IN Avi But I Try All Converter To Set The Video But IT's Don't worck :( Pls If Some One Can Help mE Just Tel ME What Can i Do To Set THis Because I Have a Mini SD Catre To And i Wanna MAke Videos In My Player Waiting For Reply Thanck You For Advance ;)

Hi Guys; I'm here for the same reason, how to encode Xvid AVIs to play on this bloody player. There seems to be a generic type of player that many of these are cloned from. They all have similar case and the UI is always nearly the same. The Rockchip decoder seems to be commonly used.

Mine is a Mambo-Flix, and it came with an AVI converter, but it gives you very little in the way of tweaking options. Worse, it produces files around 300-400 MB, which is far too big.

I have been making AVIs to play on my Pocket PC, using very low bitrate 2-pass Xvid, and WMA for the audio at 22k. This works pretty well and a typical movie comes out around 65-75 MB. The picture quality is more than adequate for the small screen. I use V-Dub, as nothing else I've found has enough flexibility to do the job.

Unfortunately, these do not play on the Mambo-Flix. I have tried all sorts of other converters, but all suffer from the same lack of real options. Why would someone leave out the capacity to set the aspect ratio? At most, they let you set it to 16:9, but it's not enough. And the file sizes are still way too big. (200-300 MB)

Does anybody here know of a good solution, or know exactly why these players don't like normal Xvid encodes? Maybe there are tweaks for Xvid which will make it happy and I can still use my Xvid/WMA PPC movies. I make the rash assumption that if the player supports WMA audio, then it should support it as video soundtrack.

Anybody who wants to know how I got V-Dub to allow WMA for the audio codec, I will be happy to tell you. That is the real secret to getting movies below 100 MB. Besides frame decimation and 2-pass encoding.

TIA

Re: MP4 player will only see AVIs (not AMV) and won't play
 

All mp4 players with Rockchips RK260xA-Chip are needing mp2 in audiocoding - there is no chance to exchange it to other codecs !

Behind AviConverter works MEncoder and he is encoding the xvid-Avis based on a 12bit calculation, most other Encoders do the same job now with 24bit calculation - theire results won't work on any RK260xA-Players ...

Try viDrop 5.5 - that gives you much more options to tweak. You could found it here in the Downloads-section.
