Hmmmm. Upon further reflection, the enhanced threading support in the newer x264 library would have no effect because using threading in the actual video encoding causes the resulting pmp to be unplayable (I remembered this from a conversation with Jonny and have been testing it out a bit myself thi...

So did you ever get around to releasing the sources? If so, can you post a link to them? :) Humble apologies, but I got lazy. :) I actually rediscovered this thread after looking for an alternative mencoder that uses updated x264 libraries myself. I'll definitely get my finger out and release the s...

For what it's worth, I've done > 50 encodes with this now, all of which have been in sound synch, so it seems solid enough. jockyw2001: I haven't forgotten to post the source....It's just been a bit mental lately in the run up to Christmas (also did an OS wipe the other day so I'm still getting up a...

Yeah, I used the svn version of x264. You're more than welcome to my source files / diff. I'll send you off a link tomorrow (bit late now) :).

I altered mencoder / x264 (groundwork done by Jonny and Magik, thanks lads) to create PMP compliant AVC files. I made a statically linked binary, so it should work on any i386 based linux install without the need for codec installs, etc. Edit: You should NOT replace your installed version of mencode...

Well....I got mencoder compiled and linked with the x264 changes from Jonny's encoder (I had to make some slight modifications to get it to work with mencoder, but it should work just fine). I haven't had a chance to actually test it yet, but I'll post a guide on how to get it built (and a binary fo...

Glad you got sorted. :)

.pm files are "perl modules". Basically they are groups of functionality that your perl script can use. Essentially, they're similar to .h files in c / c++ (no perl heads pouncing please, yes they're different, but conceptually it helps to view them this way for somebody learning). You sho...

uNn99: Any chance of posting the changes you made (a diff file would be great) to mencoder to get it to make pmp compliant avc files? Or you could point me to somewhere else that describes the steps. I'm happy to edit the source directly, once I know what to do. :) I use linux and would like to comp...

@Khannie: (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) I've looked back through this thread to try to gather the various methods of linux encoding together. (Apologies for cluttering this thread) I'll p...

Just wondering if there's a coherent post / page for linux encoding anywhere? I'm more than willing to share my experience. My encodes (using the modified x264 + pmp muxer perl scripts) work about 80% of the time, the other 20% are consistently losing sound synch slowly throughout the video. Wanted ...

mp3 support is there already, so adding it as an option wouldn't be very difficult, but the psp natively plays mp3's anyway. Personally, ogg support (in video, or as a separate supported file type) would make me smile. :) It's a much better codec below 128K, and things like cartoons could be made ve...

PMP Mod v2.02 is out. :o After the AVC release, I didn't expect any further development on the "standard" PMP Mod. Out of interest: Why is it that you have done further work on it given that the AVC player is technically superior? The only disadvantage I've seen with it is increased encod...

@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) Didn't know ...

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 ...

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 Nice one. Thanks for the heads up on that. I really missed that...

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 --pro...

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 ...

i think you can still use multithreading if you do multiple passes (only be sure to do the last pass with 1 th only) 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 thro...

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...

As this topic went too long, maybe there is a similar HOWTO in the previous pages... 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 t...

You sir, are most welcome. :)

Sorry man, I misinterpreted and thought you wanted me to rerun ffmpeg. I've emailed you the log from the muxer in a zip. I sent it to the email address listed on your homepage.

Ok, I'm at my linux box now. The actual command line I used was: ffmpeg -i inputfile.avi -an -vcodec mpeg4 -vtag xvid -s 480x272 -b 850 -threads 2 outputfile.avi Version / config information from the command line is: ffmpeg version CVS, build 3276800, Copyright (c) 2000-2004 Fabrice ...

(maybe you already know this :) Nope. ;) I didn't see that they were included. Probably should have looked harder. :) (what command line and ffmpeg version are you using?) I'm working off memory here (I'll post the actual command line tomorrow). ffmpeg -i inputfile.avi -an -vcodec mpeg4 -vtab xvid ...

First post....I know they don't carry too much weight. Anyway: First off I just wanted to say thanks to Jonny and the other add-on developers. I love my psp primarily because of pmpmod. Commute? What commute? :) Secondly: I did manage to get the perl muxer to work on linux. Here's what I did: First ...
