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:

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 :)

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.

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

can pmp mod work on a 1.0 firmware?

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:

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

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.

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-pos-support-media-apps-psp-homebrew-applications/pg/12/fid/8671/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.

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.

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

@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

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

No worrys mate! ;)

Yeah it works mate, why didnt i think of that earlier...
Cheers Shonen.

I,ve noticed that when using the command line the picture can be blockie in parts, is there any way or incorperating 2pass into the command line?

@jonny

request: a tiny program to join several pmp files (avc)

would that be very difficult ?
