Shonen, i'll see what i can do. ;)

therock003, are you using a PSP fw 1.50 or 2.0?
Dunno if it could make any difference. I'm on 1.50.
Later,

edit: also, try to redownload the PMP, maybe it got corrupted during transfer.

I keep getting this error when I try to encode a file to x264:

[accepttheownage]

Nevermind, fixed the problem.
I made my top line look like this:

[Shonen]

Alcahest, thanks in advance ^_^

therock, what Alcahest suggested (bad download) is very likely. Try downloading the file again. The moment you specify where the video crashes ("jump from the train") isn't a moment I encountered problems at.

@jonny:

I have recompiled a Mencoder with a patched x264 lib, and set
mod->param.i_level_idc = 30;
mod->param.b_pictiming = 1;
mod->param.b_aud = 1;

but when I build a avi with this cmd
mencoder -nosound -ovc x264 -x264encopts 8x8mv=1,4x4mv=1,i4x4=1,no8x8dct=1,bitrate=320,bframes=0 -vf scale=480:272 -o test.avi 1.avi

and mux it to pmp-avc, it can not work;

Hi yoshaw,

FPS= rate/scale

Thus, for example, 25 fps (PAL) is 25000/1000=25. 25/1 also works.

29.97 (NTSC) is 8000000/333667=29.97

Etc.

You can calculate this with calculator to get the desired framerate within the muxed pmp file. Normally, the muxer detects the .txt file that is created alongside the 264 stream, and correctly enters the rate/scale ratio itself.

BTW Johnny, could you take a look at the problem of red being left when there's movement cos I realise that the ASP ver of pmpmod by you has that problem too.

You can find it around the last few posts in the subtitle mod of pmpmod thread.

Thanks.

@cooleyes:
i'll try to make it work the next week

@yoshaw:
we are still here :)


btw, a new avc version is out:

http://jonny.leffe.dnsalias.com

- Added zoom, aspect ratio, luminosity boost.
- Now runs at 120mhz, in the worst situation this should still give 37-40fps (if someone experience stuttering, please contact me).

Battery consumption is around 20% for a 2 hours movie.
Key mapping is slightly different from PMP Mod, the next PMP Mod version will use this mapping too (many thanks to DickyDick1969 for testing this combination).

Keys while playing:

triangle = exit
o = toggle osd

square = pause/play
left/right = rw/ff
x + left/right = faster rw/ff

up/down = change volume
select = cycle audio streams

left/right triggers = change luminosity
start = cycle aspect ratios
x + up/down = zoom up/down

[csuper]

As usual... :
T H A N K Y O U J O N N Y !!!!!!!!!! :)
I will test that IMEEDIATLY :)

Ps : in a previous post I ask a little question about mp3/aac settings... so what do you think about it ?

csuper.

[jonny]

afaik the only accellerated audio dec is for atrac3 (i'll probably never support this format)
aac/different sample rates gives a lot of complications in the player and/or in the muxer (anyway i think at this stage there wouldn't be speed problems in both pmpmod/pmpmodavc)
i prefer to focus efforts in other stuffs first

[Shonen]

Ran some tests on 1.01.

Lord of The Rings 1 hour 768/128 kbps clip - ok
Eri Nobuchika - Voice - 4 minute 4000/128 kbps b&w music video - occasional, discrete cracks and pops audible -- no problems in 1.0
Utada Hikaru - Keep Tryin' - CRF22/128 kbps (40 mb, 4 minutes)- many stutters -- no problems in 1.0
Black Cat Episode 3 (anime) CRF20/128 kbps - ok
Alcahest's FFXIII trailer (which is 1500/192 I believe)- ok

So kinda a mixed feeling for me. It seems that everything above 1000 kbps may or may not stutter. In most cases, this bitrate is not necessary, but it's a bummer when you'd like high quality on some harder-to-encode source material (darkness, few colours or greyscale, lots of gradients, fast camera movements) 222mhz enables UMD quality and bitrates, so I guess it's kinda a psychological thing as well. Perhaps 166 mhz would be sort of a sweet spot?

On the plus side, I love the luminosity and zoom features. Thanks for those. Since we're talking features, would a replay function be possible? Would be great if you'd want to loop cool trailers and other short clips a few times.

[psp]

Thanks!!!!!!!!!!!!!

[scyrax]

Actually 120mhz was enough for performance for I`ve tested a 480x272 30fps clip with very complex scene at quantizer=10 and peak bitrate reaches to 17000kbps without stuttering.

but there is another problem with audio:It seem that it usually accompanied by some random noise,similar to a very very short stuttering at about 0.2 sec, especially often after forward/backward.and this noise was performance relative,clip at low bitrate occurs much less than very high bitrate.and for the same clip, I`ve also found that pmp avc 1.0 at 222mhz the noise was less frequent than 1.01 at 120mhz.(you may not hear it while using external speaker,but a sensitive headphone)

PS:
In fact this phenomenon I`ve found does exist in pmp mod 2.01,a clip without stuttering with average bitrate at 3000kbps was also much more frequant than at 1800kbps.(BTW,the audio encoding settings was 192kbps cbr)

[Shonen]

Scyrax, what you're describing is exactly what occurs with my encodes as well. Sorry if my description was wrong, the video itself doesn't actually stutter, indeed. It's more of an ultra short "pop" or "crack" that occurs on the audio now and then, and which is only audible when I put in earphones. After a few more views I realized that I was really quite the whining little b***h. Fullscreen AVC is soo sweet, and prolonged time away from the AC cord is mighty fine as well.

I can always start PMP Mod 1.0 for those few ultra-high quality encodes or I can compile a PMP Mod version with jonny's fantastic source code and adjust the clock back to 222/222/111.

And now just to learn how to do it..lol.

[k0nan]

Did anyone have any luck on recompiling mencoder.exe with the modified x264 library for compatability with PMP AVC?

I prefer mencoder for encoding on machines which I can't install codecs (needed for AVS scripts/Vdub) or .net framework (xvid4psp) on.

[jonny]

about the audio, i'll upload a test version today (i have some ideas about what could be the cause)

[jonny]

ok, there is a test version here:

http://jonny.leffe.dnsalias.com/tmp/tests/pmpmod.rar
( too late, link removed :P )

arex, Shonen, scyrax, can you verify and tell me your impressions?

[Shonen]

Joy to the world, both culprit videos (Utada Hikaru, Eri Nobuchika) are crackle-free now! What did you do?

[scyrax]

Yeah,audio was perfect now~ Excellent work jonny :)

[jonny]

[Shonen]

Well, excellent job, jonny. Thanks for fixing it so quickly.

I've ran 1.01 virtually non-stop from full charge to shutdown and was able to reach about 4 hours. Having said that, I've sometimes run it on the internal speakers on pretty loud volumes, and the battery pack I used is the very first that came with my PSP when I got it back in September 2005. Will test it again tomorrow for confirmation.

[Shonen]

Got up to 5:30 hours today.

I was thinking about that replay/loop thing I mentioned earlier. I don't know how to code, but wouldn't be the logic behind it that if the clip ends ("p->semaphore_show_done" in pmp_play.c ?) there would be an "if" paramater stating that "if" a loop command is issued (possibly mapped to the "home" or X + Ltrigger/Rtrigger), the clip would not close ("pmp_play_close(p)" ?) but instead start over at the beginning of the clip? For the interface module, there's a little room left on the right of the GUI, the word "loop" would just fit.

Anyway, just brainstorming. Sorry if I don't make sense.

[jonny]

[Shonen]

Well, battery life is much better than with XMB or PSPlayerMT (the latter burned through the pack in about 2 hours due to 333mhz).

Well, about the loop, at least I seemed to be thinking in the right direction. Perhaps if I ask for some help of my IT-degree neighbour I could try and figure it out.

What features/fixes are prioritized for you right now?
