i assume you have installed the splitter in this way:

regsvr32 pmpsplitter.ax

now, the splitter alone doesn't work, it is supposed that you also have an h264 directshow decoder installed

you'll probably solve installing ffdshow:

I just wanted to say thanks for this. :)

I recently removed windows from my home PC and I thought I was scuppered because the x264 doesn't natively support avi files on linux.

More thanks to 606u are in order for the .c patch to fix the empty text file (and thanks to Jonny for the simplification).

I'm available for linux testing at any point. I usually drop by fairly regularly (though post infrequently). A PM with testing request should suffice. :)

I have ubuntu 6.06 running the k7-smp kernel.

Hi.
Could you please make rw/ff more like in pc players ( +/- N sec) ?

hi!

first of all let me just say - thx for a great psp app!

one of the earlier versions of pmp mod had a bookmark function. it auto saved my last position in a pmp movie, allowing me to resume where i left off.
is this something you will readd in a future version of pmp mod? it would be great if the bookmark could be set with a push of a button :)

The POS feature was added in a mod of the PMP Mod (Malloc/Raphael/...), but it was never implemented in the core PMP Mod because Jonny dislike the way it works (with the addition of .pos file)

I asked him if he would add this feature to the core player, he had said "i will think about it, but with an another method" ...

So it' up to him... has you can see...

ok, thanks for the input. :-l

i really hope he implement it. i miss it alot when watching full features 1.5 hour +, and i have to shut my psp down in the middle of it all. my comute to work takes about an hour or so.

all i can do is pray then ;)

no, too much complications

exactly what i want to do ( but i don't know exactly when i'll do this :P )

hi jonny just a question.. what is the purpose of "debug level" in pmp muxer avc??

it show more infos if you enable high values
(it's useful for me to identify eventual problems)

Khannie · Post by **Khannie** » Thu Jul 06, 2006 10:31 pm

I have found a bug in the x264 app on linux (edit: I don't have access to a windows machine, so I'm not sure if it applies there too). I'm not sure if it's related to the changes that have been applied to make it pmp compatible.

Specifically, if I use the --threads flag to encode, it improves encode time slightly, but the player will not play the file. The resulting output files also differ.

mylogin@computa:~/temp/small$ cmp unthreaded.pmp two_threads.pmp
unthreaded.pmp two_threads.pmp differ: byte 57, line 1

I should also point out that on linux I had to run the x264 app in the background /before/ kicking off the mplayer app (which is the input to the pipe) instead of the way 606u's script does it. I wont speculate on why this is (though I have some ideas).

I haven't tried 2 pass encoding yet, but I've seen some limitations in the single pass encode. I'll give that a bash.

On a more positive note, I was stunned at the smoothness of the playback from the pmp mod avc. Well done Jonny and Magick. Really great job.

Last thing: Jonny: Is this the kind of thing that you think should be kept in a separate thread? If so I'll move it to it's own thread (I was considering making an "encode for pmp mod in linux" thread anyway).

jonny · Post by **jonny** » Thu Jul 06, 2006 11:39 pm

yep i know
when you enable more than 1 thread, the generated stream is no more compatible
for example, with 2 threads, the frame is divided in 2 parts and the data is stored in 2 different NALs, the psp decoder seems to don't like this
i think you can still use multithreading if you do multiple passes (only be sure to do the last pass with 1 th only)

your post is 100% ok
about what to post and not post here, the message was mainly directed to the discussion about mediacoder (too much unrelated to this thread imho)
what i also don't like here, are discussion/requests about basic encoding things that can be easly "googled"
actually the discussion about x264 under linux was quite technical, informative and useful

I'll try this out today and report back (probably tonight GMT). I'm not sure if there's a more convenient way of getting the input to the x264 program (on linux) than playing it through mplayer twice. It wont affect performance, but it might alter the output.

Nice one. :)

Khannie · Post by **Khannie** » Sat Jul 08, 2006 2:37 am

OK...as Jonny suspected threading works for the first pass in a two pass encode. It improves first pass encode speed by about 15-20% (judged by fps rather than a hard measurement) on a dual core (or multi-processor) system.

There is a noticeable improvement in quality using a 2 pass encode IMO.

One thing you have to change is the crf option as it doesn't make sense with a 2 pass encode. I replaced it with --bitrate. Your own preference applies here. I used 1000 and 850 and couldn't notice any difference between them (though there was a noticeable drop in filesize :)).

The relevant lines in my shell script now look like this:

Code: Select all

PIPE=/tmp/pipe.y4m

rm -f $PIPE
mkfifo $PIPE || exit 1

~/install/bin/x264 --pass 1 --threads 2 --progress --bitrate 850 -A all --level 3 --pictiming --aud --no-psnr \
    --thread-input --output "/dev/null" $PIPE &
mplayer -benchmark -nosound -quiet -really-quiet \
    -vo yuv4mpeg&#58;file=$PIPE -vf scale=480&#58;272 "$1"

rm -f $PIPE
mkfifo $PIPE || exit 1

~/install/bin/x264 --pass 2 --progress --bitrate 850 -A all --level 3 --pictiming --aud --no-psnr \
    --thread-input --output "$2.264" $PIPE &
mplayer -benchmark -nosound -quiet -really-quiet \
    -vo yuv4mpeg&#58;file=$PIPE -vf scale=480&#58;272 "$1"

You should note that I have forced the width and height to the maximum. To use 606u's built in sizing, change 480:272 to $WIDTH:$HEIGHT

edit: It's probably not necessary to remake the fifo, but it does no harm.

Hope this helps someone. :)

Khannie · Post by **Khannie** » Sat Jul 08, 2006 7:22 am

Only thought of windows users much later....and I think it warrants a new post:

The same encode style will of course work on windows, but you don't have to bother with the mplayer / pipe messing. Instead your complete 2 pass, threaded x264 encode would look like this:

x264 --pass 1 --threads 2 --progress --bitrate 850 -A all --level 3 --pictiming --aud --no-psnr --thread-input --output NUL myVideoFile.avi

x264 --pass 2 --progress --bitrate 850 -A all --level 3 --pictiming --aud --no-psnr --thread-input --output outputFile.264 myVideoFile.avi

As an answer, I quote Xtrusion from PSPU, who created the easy 1.5->1.0 downgrader:

Xtrusion wrote:Remember that the 1.00 version still hasn't got any special applications, so there isn't any reason to leave 1.50 (unless you're a developer).

And yes, PMP Mod should work on 1.0, though I didn't test it yet. Just use the non-% single folder from the release.

Just a bit of help please lads, am having a problem with VDUBMOD i scoured the forums looking for an answer but to no avail.
I have downloaded and installed Jonnys X264vfw fix, ran it and encoded with VDUBMOD used BEHAPPY to create audio and muxed with PMPMOD AVC, however it will not play on the PSP just gives me a black screen.
Am converting using AVI SYNTH SCRIPT (.AVS) there isnt a problem with it as VDUBMOD opens.
It may be simple but i just cant figure it out, any help at all would be apreciated. Thanks.

Shonen · Post by **Shonen** » Sun Jul 09, 2006 7:16 am

Try encoding the same AVS with jonny's own x264 build or with the patched mencoder. See if that works. Try limiting general encoding questions in this thread, as jonny has pointed out. Perhaps you could start a thread over at the PSPVideo9 forums.

In other news, I saw this on PSPUpdates, being the re-addition of the .POS save/restore feature after stopping the playback: http://dl.qj.net/pmpmod-avc-1.02-sub-po ... /catid/140

Also, I quickly copy/pasted some custom XMB graphics for the eboot, which you can add with programs like PSPBrew. I got the picture from the European official MyPSP.com site. If anyone wants, I can also post the modified eboot.

Sorry bout that Shonen, will do.

Khannie · Post by **Khannie** » Sun Jul 09, 2006 12:30 pm

Not sure if this one is a bug or not, so I thought I'd better report it.

I altered the bframes and iframes settings in the x264 command line (as I was encoding a cartoon). I'm still learning as I go, so there may be an error in what I did, but the encode seemed to go without a hitch.

I got an error trying to play the resulting PMP file on the PSP though.

Code: Select all

"avc_get&#58; sceMpegAvcDecode failed"

The iframes / bframes option I used to encode was:

Code: Select all

--ref 9 --bframes 5

The resulting pmp file was /very/ small (38 megs for a 22 minute episode inc 112kb mp3 sound). It was a single pass encode using crf of 25.

edit: ok....just in case I was being a big noob....I went back through this thread and found this:

jonny wrote:you should post the full parameters set if you encounter problems
(some parameters may generate incompatible stream, i'm interested in this type of feedback)

so....

Code: Select all

x264 --progress --crf 25 -A all --level 3 --pictiming --aud --no-psnr --thread-input --ref 9 --bframes 5 --output output.264 $PIPE

ofc, on windows, $PIPE would just be your avs script, or avi file. :)

606u · Post by **606u** » Sun Jul 09, 2006 6:02 pm

It doesn't like B-frames, but I might be wrong.

jonny · Post by **jonny** » Sun Jul 09, 2006 6:25 pm

@Khannie:

x264 support only uncompressed avi (both on windows/linux)
on windows we use avisynth to frameserve, there is a minitut some pages ago
(in case you have missed there is also the possibility to compile mencoder with the modified x264 support - so no need to pipe or frameserve)

@Sudds:

i need to know:
- your psp fw version
- pmpmodavc version used (1.02? mine? Raphael?)
- are you using the settings suggested in the screenshot?
- muxer version used
- you could also encode a small trailer and upload it somewhere

@Shonen:

actually a black screen report deserve some examination, this is not a simple encoding question

@606u:

yep bframes doesn't works

Sudds · Post by **Sudds** » Sun Jul 09, 2006 8:55 pm

@ Jonny
My firmware is 1.50.
I,am using PMP Mod AVC v1.02
PMP Muxer AVC v1.01
I have also tryed the X264 Modified version
and the x264vfw Modified version.
All downloaded from your site.

Shonen · Post by **Shonen** » Sun Jul 09, 2006 9:17 pm

Try making an "encode.bat" file, edit it with notepad, and enter this code:

Code: Select all

x264 --bitrate 512 -A all --level 3 --pictiming --aud --no-psnr --thread-input --progress --output youroutput.264 yourfile.avs

Then run encode.bat. This is the most basic command line jonny's suggested, and it has always worked for me.

Then mux the youroutput.264 and the 44.1 stereo mp3 file with the muxer, personally I've stuck with version 1.0 of the muxer.

And sorry that I waved my little finger a bit earlier ^_^

Or you could try upping the bitrate (768 for standard DVD content, and 1000-1500 is great for flashy trailers) or using CRF (16-22).
