I've recently tested mencoder (used a slightly modified version of that .bat file from arex). The conversion went fine but when I tried the file in PMP I got this error:
"pmp_lib_open: first frame is not a keyframe"

I saw someone had the same problem, but does anyone know how to fix it?

@arex
Nice icon and background!

I'm having a little trouble with audio.
I had an mkv file, so I demuxed it to avi and aac. I XviD'D the avi with virtual dub, but the aac is killing me. I converted the aac to wav using QuickTime 7 pro, then converted the wav to mp3 44100Hz 64kbps stereo using Goldwave. The mp3 sounds fine when I play it, but when I run the muxer, it gives me the "sync" problem when it reaches the audio.

What can I do?

fisrt of all, on my site i've added 2 sections, "Common problems" (everyone should look here before reporting a problem) and "Guides" (i've added EdwardFMA guide - thank you! - plus, i'm accepting submission of other guides too)

now, some random answers :)

@Everyone offering graphic:
first, thanks for this.
but making nice gr. stuffs inside the app will subtract too time to new features and optimization (i'm returning to a reduced free time, my real job is waiting me the next week).

anyway adding a simple icon and bg is not a problem.
since there is more than one, offering graphic help, i propose everyone interested to post a preview (like arex did).
i'll keep every work in the first thread and i'll decide what to use at the end of the next week.

@RATiX:

forgot to answer you, i'll release well written specs when i'll get the time to do this :)
anyway the pmp format is quite near to a raw format

pmp_lib.h contains headers for video/audio

the structure is something like this:
- video header
- video indexes
- raw frames
- audio header
- audio indexes
- the mp3 (with eventual tags stripped out)

video indexes is an array, in each value:
value & 1 -> indicates a keyframe or not
value >> 1 -> is the video frame size

audio indexes is an array of bytes, in the current format each value get only 0 or 1 (this replicate the "Padding bit" in each mp3 frame)

RATiX:

you could try FFMPEG (i'm discovering some problems with low bitrates, besweet too seems to output non muxer compatible stuffs with br < 112)

ffmpeg -i youraudiofile -ar 44100 -ac 2 -acodec mp3 -ab 64 out.mp3

jonny, there is no way to implement an aspect ratio fonction ? so many movies are in widescreen, and not 16:9 for example. an autokeep aspect ratio in pmp should be amazing. But maybe too much performance issues, or dunno ... could you tell me more ?

jonny · Joined: 22 Sep 2005 Posts: 351

i don't understand exactly your problem.
can't you encode widescreen content to someting like 480x200 or 480x208?

well first i want to say great job jonny

then i want to say great job arex because youre method is the best i tried

just i erase the last line with the pmu because it wasnt working with me so i do it manually and i also modify 600 to 824 and 800 to 1024 + the sound in 192 kbps (i dont know if it change something for the video resolution but i really want the best quality ever (i dont care of the quantity)

so i encoded "tom yum goong" 700 mo xvid in approximatively 20 minutes maximum (but i think it depends on ure avi source file because i try now another divx and it seems that it will be more like 30 minutes (thats still very fast) , it gaves me a 478mo pmp file

so to everyone no need to think much , use his method if you dont know what to choose

but i really want to ask you (arex) or to anyone else if i can change the .bat settings to have the best quality we can have

thanks a lot again to everyone who contributes to make this thread very interesting !

special thx and greets again to jonny !!!

actually there is no resizing
every clip with width < 480 and/or height < 272 will be simply centered.
so both widescreen and 4/3 content can be used with full quality (4/3 should go to something like 360x272)

there are problems only with clips like 320x200, since there is no zoom function and the clip will not fill psp width nor height

Thanks Jonny. Damn, couldn't get in touch with you any other way so I had to register here :)

GREAT work! This is what I've been waiting for, now I can actually watch movies without suffering too much. And the encoding-stuff is faster than psp video 9 etc. I think.

I've tested a few clips and movies, both with virtualdub+belight, and now with MEncoder. The batch files people posted here were really great, and it's so easy. Just one line and everything goes smoothly. No need for me to setup stuff in 2-3 apps.

The only thing I'd like to see is some display of time.

Once again, thanks. This is the greatest app since ISO emulators.

Edit: I forgot to mention that the playback is awsome, no fps-drops etc so far. But I guess you knew that :)

I wanted to give my thanks to you jonny, the player is great, and now we can finally unlock the full video power of the PSP. My understanding of container formats is limited, so is there a reason why a custom container has to be used? The container wouldn't be much of a problem if there was some kind of fully-automated frontend to use for batch encoding with customizable settings (resolution, bitrate or target size, etc) for each input/output file.

Well I'm completely staggered by this, the very same day that I was cursing Sony for crippling the video on the PSP, jonny goes and does this. Fantastic work!

I've wasted most of the last 24 hours playing at converting files to get the best results. Currently I'm favouring using AutoGK to do most of the work, especially if backing-up DVD files.

Anyway, I wanted to mention a problem I'm seeing with ALL pmp files so far (regardless of how they are converted). The problem is smearing/blurring/shadowing. It's most noticable on brightly lit scenes with fast edits or lots of movement.

Take a look at the following example clip.
First try the avi version on your PC, the problem cannot be seen. Then try the equivalent pmp version on your psp, watch the characters moving you will see they blur/smear as they move around. Also watch the edits, you will see shadows of the previous scene for a split-second.

(change hxxp to http to get this link to work, yousendit.com doesn't like to be linked to)
hxxp://s37.yousendit.com/d.aspx?id=2ZNQR4HBE6B5X11VXWIZSW4SYH

This is not a major problem, and you may have to look hard to see it, but now I've noticed it, it's really bugging me!

Any ideas what's causing this?

I think you're right jim, the example video from that thread also shows the same problem.
Thanks for setting me straight.

Hi johny,

Since you asked for it, here's my preview image..

I really like the clean Media Center-like look, and decided to give it a try.

You can download the package HERE

And follow the readme instructions (replace the original PMPMOD% directory with the PMPMOD% directory included in the zip file)

Thanks to Pochi for making these images. I just inserted them images in the eboot.pbp to make the player look classy. That last is my only credit in here! Again much props to Pochi.

Here is how PMP would look like on your PSP LCD if you just replace the PSPMod% folder with the one linked below

Thanks for all your hard word Johny!

Just a tip for anyone who wants to seriously louden the audio track rather than using belight/sweet option (as its quite crap).

I've found its far simpler to do the following and get great sound amplification for movies IF YOU HAVE THE DISK SPACE! 2hr movie needs around 6gb space for the stream

Using the original source movie you used to encode video segment do the following -

Start a new encode as follows:

Video set to direct stream -

Here's the trick - Audio - full processing mode - compression selected as NO COMPRESSION PCM

Then under the same tab you'll find a volume setting - raise it to between 600 - 800% and encode your AVI as normal. (this process will take around 5 minutes for a 2 hour film)

-----------------------------------------------------
Follow up using belight/sweet

Load up belight/sweet

choose your new volumised avi to create your mp3 for muxing and you should be pleased with the result.
-----------------------------------------------------
to recap simply:

1.encode your video only without audio
2.encode your audio by streaming and volumising with a new avi file as explained above
3.convert volumised avi to mp3 with belight/sweet
4.convert original video only encode with new mp3 taken from volumised avi using the muxer.

I hope I have explained that well - dont be put off by the second avi fil encode just to get volume increase - its only 5 mins and the rewards are great results.

All the best

J.

Is there any quality loss with this method?Increasing to to 600-800% isn't it very loud?

What if instead of dynaic compress (it is crap i aggree)we use the boost option on belight,will there be any problem?

Also jonny,would it be able for you to make a muxer that process batch files.If i have a folder full of files a.avi-a.mp3,b.avi-b.mp3 and so on,to encode them all at once?
