PMP Mod v2.02 & PMP Mod AVC v1.02

jonny · Post by **jonny** » Tue Apr 18, 2006 10:00 pm

@pkjai1:
can you try this:
http://rapidshare.de/files/18309067/pmpmod.rar.html
and tell me what happen
(be sure to put some files on "ms0:/PSP/VIDEO/" - no matter what type of files)
note: if works, at the end you'll need to hold power for 10 secs to power off the psp, there is no exit :)

@all:
is there someone with fw 1.5 us experiencing this strange behaviour (or a correct behaviour)?

@jockyw2001:
tested, the final binary gets stripped at the end, so there is no difference (actually the version without -g was a little bit slower lol)

@excalibur:
the detailed answer to this require a work that i'll be not able to do for some time - i would say that everything is possible given that you have enough time :p

Woot! It works!
But it didn't load out.pmp from the demo you told me to try. It's probably because it was muxed in 1.02 format.

-pkjai

Edit: Something interesting happened. The remuxer said that out.pmp is not a valid pmp file.

Code: Select all

G&#58;\PSP\VIDEO\out.pmp&#58;
Processing video ...


Status&#58; &#91;not a valid pmp file&#93;

The PSP gave the same error before too. It also said that it wasn't a valid PMP 2.00 file but I figured it was just muxed differently. I figured wrong.

yep, this is normal.
the pmp in the old demo works only with the demo (the format is changed with pmpmod 1.xx and is changed again with the 2.00).

you should use the remuxer with one of the trailers in the first message of this thread.
(those trailers are encoded for 1.xx)
**EDIT: now 2.xx versions are up**

thank you for the tests!

anyway it's strange, it seems like the home button results always pressed in your psp.
have someone an idea about what could be the cause?
(a behaviour of the 1.5 us firmware or something strange in the pkjai1 psp?)

arg jonny, i'd like to help but i got a psp fw 1.0 and it's working perfectly fine on it.
Here's is a rather nice Sony PMP for tests btw (PMP v2.00)

@jonny: why is it that PMP must run in kernel mode? only because it uses the ME or is there more?

Hmmm. I don't know. Maybe I should take apart my PSP and clean out the thing. It might work then. For now i guess I will just use the version you gave me without the exit option.
That works pretty good.

Thanks a lot.

in this version home function is replaced with circle
http://rapidshare.de/files/18394788/pmpmod.rar.html
so you can exit

@JockyW:
afaik only due to ME usage

Put it in the program folder or c:\windows\system32

thanks, but now when i run the pmp_remuxer.exe ( to get 1.xx PMP to 2.00 PMP video) nothing happends more that something black popup closes in less than a half second.

Alcahest · Post by **Alcahest** » Fri Apr 21, 2006 3:12 am

you have to drag and drop your PMP 1.0 onto the program icon, then it will be automatically converted to PMP 2.0.
Or you can also use the program in a DOS window.
Later,

Hello

Why "select" and "start" buttons don't work in this new version ?
(i.e. to choose video screen size and see time while seeing a video)

I had found these functions very useful ... :-(

And I prefer the 1.2 graphic interface with time and battery indications.

But when coming back into the menu and highlight our last choice is great ...

bye.

PMP Demuxer v1.00

The demuxer is a command line application, the easyest way to use it is to drag and drop files over it (the files will be written in the same dir of the pmp, along with the log file containing the result of the operation).
The avi file created is slightly out of specs, when bigger than 1GB. Anyway there should be no real problems up to 2GB.

The circle is closed :)

Awesome, thank you Jonny!
See you,

First post....I know they don't carry too much weight. Anyway:

First off I just wanted to say thanks to Jonny and the other add-on developers. I love my psp primarily because of pmpmod. Commute? What commute? :)

Secondly: I did manage to get the perl muxer to work on linux. Here's what I did:

First I needed to install the perl vector package. I'm running ubuntu, so it was just:

sudo apt-get install libbit-vector-perl

This should be available with the standard apt repositories.

I'm sure it's handy enough to do this through CPAN also.

Then ffmpeg was generating files that didn't have matching header frame numbers and and actual frame numbers (the difference was 1 frame), so I commented out the lines in the avi_parser.pm file that were causing an exit on this error (lines 601 and 612 in the latest source....search for "number of frames").

Everything then worked. There was an error from the muxer on exit, but the resulting pmp file works like a charm.

Hope this helps someone else out. It puts me one step closer to ditching windows.

OK, now I have a question. I used the demuxer and it worked great. i got two files an avi and an mp3. I used VirtualDubMod and was able to put them together. The problem was I got a 44gig avi file. Luckily I had enough room on my harddrive. I then used this file to make an SP MP4. I am guess what I forgot to do was set a compression in VirtualDubMod before I saved the combined (or is it muxed) avi.

My question is what compression scheme is recommended and what settings to reduce the file size but maintain decent quality?

Thanks.

jonny · Post by **jonny** » Wed Apr 26, 2006 1:34 am

@Khannie:
actually the modules needed are included:

Carp-Clan-5.3.tar.gz
Bit-Vector-6.4.tar.gz

installing each module is easy:

perl Makefile.PL
make
make test
make install

(maybe you already know this :)

about the avi problem, seems an ffmpeg bug.
on windows, using a cvs compile (9/9/2005) all seems ok.
i've done some tests like this:

ffmpeg -i vid.avi -vcodec xvid out.avi

and the generated avi seems fine.
(what command line and ffmpeg version are you using?)

you could try to run:

perl pmp_muxer.pl -v video.avi -a audio.mp3 -o out.pmp -d 9

and send me the log file, so i can have more infos.

@JFox:
Video -> Direct stream copy
This will leave the video stream intact.

My question is what compression scheme is recommended and what settings to reduce the file size but maintain decent quality?

This question goes out of the scope of this thread
(do your homework, there are tons of resources on the web :)

JFox · Post by **JFox** » Wed Apr 26, 2006 2:07 am

Thanks for the response, but I don't think this is out of the scope of this thread. The question was in directed towards the demuxer and your recommendation since you would be the one to know what type of file the avi and mp3 was outputted from the demuxer. All other web resources I found work the other way; removing audio.

Anyway, thanks for the answer and the demuxer, I'll give it a try.

Eingang · Post by **Eingang** » Wed Apr 26, 2006 3:36 am

LOL thanks for the demuxer, Jonny...
will test this later.... nice nice ....

how good you see the chances of seeing a plugin to support media players like VLC, Winamp or WMP your PMP files somewhen?

maybe, when i'll have no more things to do on the psp side
(writing a directshow filter could be a funny thing to learn, but it's probably more easy to directly port the entire player)

Nope. ;) I didn't see that they were included. Probably should have looked harder. :)

jonny wrote: (what command line and ffmpeg version are you using?)

I'm working off memory here (I'll post the actual command line tomorrow).

ffmpeg -i inputfile.avi -an -vcodec mpeg4 -vtab xvid -b 850 outputfile.avi

(not sure about the vtab part...I got it from the ffmpeg faq. using -vcodec xvid caused a failure).

I'll also post the ffmpeg version tomorrow. But it's almost certainly whatever version comes with the standard apt repositories in ubuntu 5.1.

It happened with two files. One was off by 1 frame, the other was off by 8 frames. In both cases I wasn't overly bothered, so chose to comment out the perl checks (I assumed it was there to catch larger frame differences).

Will do. If I haven't deleted the affected avi files that is.

Khannie · Post by **Khannie** » Wed Apr 26, 2006 5:28 pm

Ok, I'm at my linux box now. The actual command line I used was:

Code: Select all

ffmpeg -i inputfile.avi -an -vcodec mpeg4 -vtag xvid -s 480x272 -b 850 -threads 2 outputfile.avi

Version / config information from the command line is:

Code: Select all

ffmpeg version CVS, build 3276800, Copyright &#40;c&#41; 2000-2004 Fabrice Bellard
  configuration&#58;  --build i486-linux-gnu --enable-gpl --enable-pp --enable-zlib --enable-vorbis --enable-libogg --enable-theora --enable-a52 --enable-dts --enable-dc1394 --enable-libgsm --disable-debug --prefix=/usr
  built on Sep 29 2005 03&#58;25&#58;16, gcc&#58; 4.0.2 20050808 &#40;prerelease&#41; &#40;Ubuntu 4.0.1-4ubuntu8&#41;

So it could well be a bug in ffmpeg. Still....the resulting PMP file plays without any issue so I'm happy.

jonny · Post by **jonny** » Wed Apr 26, 2006 7:27 pm

maybe the problem is trigged by "-threads 2" (?)
(the log could help me to definitely exclude problems in the muxer)

Khannie · Post by **Khannie** » Thu Apr 27, 2006 12:23 am

Sorry man, I misinterpreted and thought you wanted me to rerun ffmpeg. I've emailed you the log from the muxer in a zip. I sent it to the email address listed on your homepage.

jonny · Post by **jonny** » Thu Apr 27, 2006 5:26 am

Thank you very much!
Yep, it's for sure an ffmpeg bug, the number of frames in the index differs from the number of frames reported in the header (there is no superindex/OpenDML chunks so there is no escape).

Has support for fw 1.5 stopped altogether?

i don't understand exactly your question :)
i would say: no
