I noticed with the AVC muxer it doesnt like it if there is a space in the output file name e.g.

pmp_muxer_avc -v out.264 -a fg1.mp3 -o family guy.pmp

but

pmp_muxer_avc -v out.264 -a fg1.mp3 -o familyguy.pmp

works perfectly. I know the xvid version didnt have this problem, may be something to look @.

Otherwise working fine Jonny again great job everyone whos had a hand in this

pmp_muxer_avc -v "out.264" -a "fg1.mp3" -o "family guy.pmp"

(this is the way you should pass command line options that may contain spaces, it's not related to my muxer in particular)

first, my english is poor. I hope u can understand what i want to say.

I tryed to make a PMPAVC from DVD, useing a dvdrip software and choice the H264 coder. Here is the setup:
http://www.cngba.com/attachments/month_0606/vfw_N6fG7YFTxyIv.png

then I use mencoder to split this avi to pure vedio and pure audio, save as .264 and .mp3.

at last, I use pmp_muxer_avc_tk.exe to muxer and it succeed, but when i played it in PSP, it shows"avc_get: sceMpegAvcDecode failed".

can u help me?

hi ,jonny,what highest bitrate through sony official psp avc decoder api can touch?:)
i have tested the 6000kps ,it works perfectly:D

New icon & launchbg from Pochi for PMP AVC!

(transparent tab)

Other launchbgs (semi-transparent & solid) on his site!

Truly a master of his art.

Comparing this modified version of avc and the avc played on fw 2.0+ are there any significant differences on performance?

Which one would you honestly say is better?

Here is a little AVC encode that i did.
I now understand why AVC is amazing; so incredibly smooth!
Check for yourself. video: 1500Kbps / Audio 192Kbps.
I think the result is AMAZING!

I kow have learned how to use Avisynth too ;)

2 tips for avisynth, when you want to use a source MPG2, get Nic's MPEGDecoder and load it this way :

LoadPlugin("c:\program files\avisynth 2.5\plugins\MPEGDecoder.dll")
MPEGSource("test.vob")

It gives much faster result than Directshowsource.

Also, you can use Avisynth to crop:
Crop(0,58,0,-58)
This must be on the line directly after the source, before "lanczosresize(480, 272)"
In this exemple, it will remove 58 pixel from the top and bottom of the picture.

Well that's it for now. Check my AVC PMP and let me know what you think!
Later,

Alcahest

i think you should lower the bitrate a little because avc is noticeable only in lower bitrates + small file size

Today i tried again.
I ripped a dvd chapter into avi with h264 coder.
Then I split this avi to pure vedio and pure audio, save as .264 and .mp3.
At last, I use pmp_muxer_avc_tk.exe to mux and it succeed. Also can play in my PSP.

But another problem happened, the avi can play well in PC. The lengths of both .264 and .mp3 are 01:48, when they played single, there's no problem.
After I mux them, the PMP has a litter problem. The audio become longer, at first it fit, but when time goes by, the audio can't keep up with the vedio.

This PMP can play in my psp, but the audio can't keep up with the vedio. The .mp3 is as long as the .264, the .mp3 is 44100Hz, it's right.

Who can tell me how it happened.

it seems you have specified wrong scale-rate

try to use the muxer posted by cooleyes, directly with the avi

Hey Shonen, I got the source on the gamespot.com E3 report. (it was only available for subscribers.).
I agree that the quality is stunning and as you say maybe a little more saturation would be even better.
See you!

Hye Jonny,

I've got som technicals questions related to the audio stream...
You explained perfectly that the PSP have some AVC optimization...
So... is there a same optimization for audio streams... ?
Actually natively the PSP can read AAC & MP3 right ?
If yes, is it hard to implement AAC on your PMP MOD ?

Also, I wanted to know with the great performance of the AVC release (fps speaking) if you unlock the 44,1 Khz limitation of the mp3 stream and instead you got a 48 Khz audio stream (a classic Xvid/Divx mp3 audio stream - without re-encoding), are the performance drops a lot.... ?
If not, do you think to add soon this feature ? ;)

Ciao.

csuper.

oh indeed, 48khz mp3 direct support would be very handy.
See you,

Alcahest

I get an error on that E3 ff video.After it runs for a while i get a SceMpegAVCDecode error.

Hey Alcahest, would you mind recoding your FFXIII video with Tweak(sat=1.4) (or any value you prefer)? Well, thanks for sharing anyways. Stuff like this softens the 600$ PS3 hammerblow, hehe.

Therock003, are you sure you used alcahest's video? Because the SceMpegAVCDecode error occurs when I try to run a transcode of the GameTrailers E3 FFXIII trailer (which seems to have some sort of broken frame in the beginning, it also crashed in the PSP's standard AVC player).
Did the video start and then crash or didn't it start altogether?

Oh, and last night, I did some more encodes. Lord of the Rings - Two Towers (last hour: Battle of Helm's Deep) and the first 5 chapters of Final Fantasy: The Spirits Within. I used 768 kbps and the results are astonishing. I had some trouble with FF:SW, because it was a telecined NTSC disc (real fps was 24). After a lot of fiddling, I simply adjusted the rate-scale in jonny's muxer to 24-1 (instead of the outlined 8000000-333667). Decimate() produced unwanted choppiness.
