Jonny, we'd like to thank you for all of your hard work. Your PMP Mod software is an amazing piece of work and a great achivement. To help people in the conversion department, we've released the Videora PMP Converter. This program is just like PSP Video 9, it is a freeware FFmpeg GUI, but it is tail...

Of course we looked at the code, how else would we have got our ThinkOutside IR keyboard working on the PSP. Even with the following simplified code, there is still some unknown delay in the PSP between reading large amounts of IR data and printing it to the screen. int irdafd, len; irdafd = sceIoOp...

This problem is still unsolved and we feel it warrants its own thread, instead of being buried in another . Problem When using an IR keyboard with the PSP and typing at a high wpm ratio, the letters do not appear on screen in real time, rather they only appear at a much slower rate. For example, say...

I was hoping it wasn't the firmware, looks like thats the culprit. It seems like there is some sort of internal buffering going on, which is totally odd since the PSP reads the IR data in real time. Nope, I'm not using your program. I'm using my own code to read in characters from my ThinkOutside IR...

We are seeing such lag on our ThinkOutside IR Keyboard as well. The odd thing is, for us, the lag isn't in the keyboard. We can quickly type out a sentence, then move the PSP away from the IR keyboard sensor, and the _all_ the data ends up being displayed but only at a "trickle". From our ...

We're curious, do you see any lag when printing characters to the screen from your IR Keyboard at high wpm rates?

Great work jonny. We look forward to seeing your idct optimizations. On another note, is anyone hearing odd audio distortions when using PMP? We never heard such distortions in the original JiniCho version, but in jockyw2001 and now jonny's version we're hearing some odd audio distortions when playi...

Hi jockyw2001, We're curious, do you think the PSP has the CPU power to downscale something like 720x480 to 480x272 and play it back with full frame rate even with optimizations? Are going to use the VFPU for IDCT and YUV2RGB once that functionality comes available in the SDK? Are you planning on of...

In case anyone is curious about this PMF Player application, we've posted our comments about it here:

Hi glitchbit, It's nice to see that other people are interested in seeing user created pmf's as we are. I'm a bit unsure why you didn't post this in our PSP Video 9 forums since most video-savvy people hang around there. As seen by those postings. > DrEggman has already done this obviously but is no...

PSP Video 9 has this functionality built into it now.

Seems to be indeed true: The most impressive creation mode is Create-a-Player. You can actually put a custom face on your character by uploading a jpeg to the PSP's Memory Stick. It takes a little bit of adjustment work, but you can make a skater that looks just like you or your favorite celebrity t...

That would probably explain why the big PSMFs don't play when you rename them as small PSMFs. Also the small PSMFs are small (144x80?) and very simple videos (not many I-frames) so it would make sense that they could be decoded in software. Playing back PSMFs of the memory stick would indeed be part...

These proc commands are likely useless without the South Korean NESPOT UMD, but we figure you guys would be interested none the less.

id like to be more specific.. sorry

Does that mean you know something?

Anyways, what really is the point of playing back an mp4 over the network? You can already do that now, without the lag.

If you are interested in knowing more about these files, I've posted a short writeup on them. Its not much, but its a start. If anyone has anything to add, let me know.

AVC playback on MS is possible, whether anyone other than Sony will be able to do this is another question.

See the AVC/H.264 section of my PSP Video codec document for info/pictures:

NinjaFish, are you seeing the same slowness is version 0.31? They recompiled ffmpeg with the optimizations set to max so hopefully that will make things some what faster. We've upgraded PSP Video 9 (Version 0.91) to reflect this new version: http://www.pspvideo9.com/forums/viewtopic.php?t=32 We stil...

Hi Guys, We are trying to compile some hard technical data on the MPEG-4 format that the PSP uses. Any information that you think could be useful to our document would be apprecatied: http://www.pspvideo9.com/forums/viewtopic.php?t=4 On another note, we have recently released a freeware FFMPEG-based...
