Hi there

Sorry I should have explained a bit more clearly

From the test avi file, I split it into 2 parts: video & audio.

Both parts now need to be joined together into a single file for playback.

Thats all

I think chrome307 has got the best solution for you guys.

I tried running dpgx4 on Fatdog64 but had python problems,
then realised I was outa my depth.

Sorry I can't help any further.

His solution makes logical sense ... but lacking the knowledge to combine those two files it leaves us in need of someone familiar with that step in the process.

Thanks for getting us this far ... surely someone in Puppy-world has a Nintendo DS and has figured this out ... we just need to find them!

Hi there

Just to let you know the next step appears to be to use 'Dpgmux 1002.exe' with WINE to see if that will join up the 2 component files.



I will have a look at it later when I have time

BTW

Are you aware that you can buy an 'add-on' to playback movies eg

Ex4i Movie Card

"Watching movies of any format like RMVB,AVI,MOV,DIVX,MPEG,FLV,3GP,ASF,WMV, and listening songs of MP3,WMA,OGG,AAC,APE,FLAC format is simple as saving them into Memory cards."

Just an update ..... I have tried loading Wine.sfs, with FatDog64-500 and that was straightforward.

However, when I tried to run the DPGMux.exe file, it failed to run even though it was setup to run with WINE. I can only guess that as it is a 32bit app that it dosen't run in a 64bit environment ( not sure ? ).

So then I used Puppy Linux 4.31 ( 32bit ) and used WINE as pet file which allowed me to run the application, but then I got an error message which was garbled onscreen in a dialog box, complaining about wine3d( ? ). As I am using an Intel gfx card, I then added the full Xorg drivers, but this did not change anything and failed to run as well with the same error.

With further reading I understand that the *.DPG format is simply an adaptation of the Mpeg1 format, so can the DS playback this format natively?

If your unsure, can you simply rename an Mpeg video that you have and simply rename the extension to DPG and play that back and let me know the results?

Python seems a bit overkill to me. I got the impression reading the wikipedia page that you'd be able to create them with just ffmpeg, a hex editor and cat.

You might want to check out this link for some code to produce the header and do the muxing:

I wonder if that's where mpeg_stat originated...

@ Warrior522

I will mux a video clip for you with hopefully the right combination of codecs and upload it for you ie m1v & mp2.

....btw I mp4 is a different container, not mpeg.

Nothing other than a properly configured DPG file will work in a Nintendo DS and a DPG will not work on anything other than a Nintendo DS.

[chrome307]

Well OK then ... looks like you'll have to wait for someone to compile it for you correctly.

Anyway here's the video clip I made with FFMpeg, it has the correct parameters for playback, but is an mpeg .... if could try renaming this to dpg and see if it works?

Is this helpful?

Would you be interested in dpg4x on Lupu 5.1

Hopefully gonna compile it within the next little while.
