Re: Looking for converter to MJPEG (motion JPEG) video
 

Hello,

same problem here, with same MP4.
As said, is a SIGMA MASS STORAGE USB, with the SG-851 chipset.

The video it came with, is rotated 90° clockwise (when played in PC) but in the damn machine is OK.

vid codec: MJPEG with Huffman table
size: 128X160
fps: 15
aud codec: IMA ADPCM mono (1 chan) 64 kb or something like that...

The CD it came with a program called SIGMA_EN.EXE and, well, it never worked.Not in Vista, XP, nor 98SE... always same response:

[There is no Resource!]

So, I´m very lost here...

Of course, I contacted the supplier. Hwa-Yee, from Shenzen, China.
They kindly suggested me I didn´t know anything about video. :cry:
Er... ok, very good, thanks...
When I insisted, their e-mail response was this (I cut and paste literally):

Dear Jose,

Thanks so much for your interesting in our ipod nano MP4 player.

Till now, no clients reflect that problems to us.I am really have no idea about your problems.I talked with our engineer he give me this information as below,
Hoping it can help you.

1.MTV means Movie.
2.All the vidio & audio fomart can be converted by AVI convert tool.the reason is not software and no need to upgrade.
3.Maybe you can try more times and download a AVI convert software from other units.
4.Maybe you can ask help from other person from your side.


Best Regards,

janice

I hope we all can get some luck with those ChiPods...

Hi, admin.. JOSLAC have a good detail.
I was working with all video converters but nothing happens.

Every day i work on it, try to try, reading and translating all china mp3/mp4 pages looking for something but nothing. I loose my money hahaha.
Some china forum pages write about it but only features, there are not software to download.

WARNING: My computer is crying.. the virus in these pages and video converters apps are so $%·&#...

Hi Guys,

are you willing to try something that sounds impossible ?

Download and install viDrop first, download the "50 new presets for viDrop" and extract them into the subdir "Presets" of viDrops installationfolder in a second step. At third, try to use the new Preset "SMART Rockchip 220x176 high.ini" and change width into 160 and height into 128 under "Advanced Settings". Change the FPS to 15 and this shown "Extra Parameter" for "Mencoder" too:

-vf-add expand=176:220:-1:-1:1

into

-vf-add expand=128:160:-1:-1:1

and convert a short video. Will the resulting video play on your mp4 ?

It could be impossible, because a SIGMATEL-Chip isn't a RockChip-Chip RK2602A, but the values are very identical. rgrds, lca77

LCA77, I tried as you said, and it did not work out... Thanks anyways...
That program is definetely only for ROCKCHIP models, not our case (SIGMA)

Besides, is not even SIGMATEL but just SIGMA SG851...

It only decodes M-JPEG video, with huffman tables

No other format will play...

I have tried:
DIVX XVID MPG FLV AMV MTV MOV etc etc etc... already 1 month on this piece of "brown"... lol...

But thanks anyways you gave me a little of hope for a few moments...

Hi JOSLAC,

Did you ever have a sample video with your player? Wasn't a very helpful reply from Janice the supplier.

Try this URL here: http://www.globalsources.com/gsol/Ge...FreeTextSearch

Global Sources is a great source of Chinese manufacturers. I did a search for "MJPEG" and that's the result. Hopefully if you look through those sites, they may have a "downloads" area where you can download the software. I've been look at some sites for you as well but haven't found anything, so will keep looking....

thnx! that´s a good one... I´m there lurkin right now!!!!!!!!!!!!!!!!!!!

I've also sound some artilces too. Try these. Unfortunately as I dont have MJPEG player, I can't use these tools to convert and test it.

Try these tools mentioned from the article above:

http://www.videohelp.com/tools/SUPER

Yup... thnx again, already knew that, and tried most of it ;-)

Ok.
I'll keep hunting as well.
Let us know if you eventually find a converter for it as it would be good to upload it here and share it with everyone else.

COunt on it... no problem...
