PSP doesn't play x264 streams/files w/o x264-pictiming-magik patch. I come back to my question, how do you know that PSP can play std h264 vid streams? (i.e. w/o pictiming tweak). I know PSP 2.71 firmware Video Player (not homebrew) can play AVC-MP4 created by 3GP_Converter 0.34(http://www.nurs.or....

You didn't read the page carefully. Look at this quote: In the muxer you need to specify width, height and fps of the video. I've patched x264 to write a file with this informations. The only patch to x264 is to make it write a small text file containing certain paramters (resolution, frame rate) f...

I am a AVC newbie, and please correct me if I am wrong. I know Jonny's PMP MOD AVC 1.02 and jockyw2001's PMP VLC Player 009 Rev4 all depend on a patched x264[1]. Why? I mean SONY's PSP player can play AVC encoded with un-patched x264, but our hacked AVC hardware decoder[2] can only deal with patched...

I check the code and find that it uses libcurl. (PMPVLC009-rev2\ffplay_resample\Makefile Line 29 uses "-lcurl") But the PSPSDK does not include libcurl. How to build libcurl for PSP? I know I can not "tar -xzf curl-7.16.4.tar.gz" and "./configure; make install" because ...

I install the latest psptoolchain on cygwin and try to compile a sample code, the following is error message: -------------------- /usr/local/pspdev/lib/gcc/psp/4.1.0/../../../../psp/include/stdint.h:83: error: conflicting types for 'int32_t' ../etc/inttypes.h:8: error: previous declaration of 'int3...

Where can I get the "PMPVLC009Rev2-source.zip"? I want to get it because Rev4 does not work for my psp 1.5 while Rev2 work well. So I want to diff the source code between Ret2 and Ret4 and try to fix it.

A similar error as you got once happened to me, shortening the directory names resolved it. which directory? Sorry, but I wasn't sure if you meant the directory on the PSP memory stick, or the directory that I have my music and videos in. If you are talking about the music or videos, then I don't t...

The pmp.ini mentiones that: ------ # use_avc_hw is heavily experimental !! # if set to 1 then automatically vid_codec = h264, aud_codec = mp3, and container = ts are set # your pmp.ini settings are then superseded use_avc_hw = 1; ------- Is it possible to set "use_avc_hw=1" to play a .mp4 ...

I have not wireless route so I can not active PSP's built-in wireless function, can I use PMP VLC to play .mp4 file in memstick, not thru wireless network?

Thanks!

Hi all,

Is FAAD2 ported to PSP? I know FAAD2 is popular for MPEG4-AAC decoder and I am looking for MPEG4-AAC decoder on PSP.

Thanks!

Hi,

Is it possible to write code to play .mp4 file on SONY PSP 1.5? (.mp4 container, mpeg4 video codec and mpeg4 audio codec, 320x240)

Thanks!

I've checked http://www.lookingglass3d.com/pspsdk/gl ... ml#index_m, and pspsdk doesn't support mmap function. Right? Who knows more details about it?

malloc's original M4.02 also works and doesn't have the sceIoDevCtl function either I can not find malloc's original M4.02, but http://www.alex-berl.de/download/PMPMOD_1_01_M4g2_argandona_src.zip has sceIoDevCtl. The key problem is: When you *format* your MS by SONY PSP's format function, and click...

I've added an entry (http://en.wikipedia.org/wiki/PMP_Format) for PMP Mod 1.02 "PMP File Format" because someone (e.g. directshow filter for parsing .pmp) may need this spec. I am not the container inventor, so if you think it has error, please revise it or let me know. Thank you! EDIT. wi...

@Raphael I noticed you used "sceIoSync("msfat0:", 1)" and "sceIoDevctl("ms0:", 0x02425818, &pbuf, sizeof(pbuf), 0, 0)" to get the free space. But there are no *detailed* docs for the two functions: ----pspiofilemgr.h Line 383--- /** * Synchronise the file ...

@therock003: I also liked the icon view very much, however it's harder to implement, since you need to open every video and generate the first frame to be used as icon and blit it scaled down on screen and all this for every screen refresh. At least the decode of the first frame is a problem for me...

I've downloaded a big .pmp file (e.g. 2GB) but my MS card is ony 512MB. I want to find a tool to split the big .pmp to 5 small .pmp files (400MB per file). Any suggestions?

Thank you!

Thanks for Jonny's help that I find the ffmpeg's profile without mmx optimization for AVC baseline decoder. I think it has similar profile in PSP. Following is profile: Flat profile: Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls ms/call ms/call n...

Actually I am looking forward to the similar tool mentioned in http://forums.ps2dev.org/viewtopic.php?p=35127, which is for PS2. Has PSPSDK similar tool/feature?

Is it possible to port this into PSPSDK? It's exactly what I want in PSP! :P

@jonny Thank you for your advice. I create Baseline Profile AVC clips and you PMP Mod 1.02 can decode "480*272 @400kbps" 15 fps smoothly but decode "480*272 @400kbps" 20 fps with stutter. Anyway, my goal is to let the 20fps-stutter clip be smoothly decoded by optimizing PMP Mod 1...

@jsgf First of all, thank you very much for your reply!!! (1) I mean "* 1/64" is different with ">>6" and following is a sample. short a = -7136; float f = (float)a/64.0; // f is "-115.500" int i1 = f; // i1 is "-111" int i2 = a>>6; // i2 is &q...

Is there a VFPU instruction for ">>1" ? Now I am using "vscl.q" to scale "0.5". If I want to ">>6", I can not "vscl.q" to scale "1/64.0" because of precision problem. (Maybe I should use "vdiv.q" to div "64" to keep prec...

@Raphael Thank you very much for your direction and I've found the paper "Low-Complexity Transform and Quantization in H.264/AVC"[1] for this issue. @jsgf Thank you very much for your code. Your code assumes block is (int *) type, but really it is (short *) type ("typedef short DCTELE...

Thank you very very much for your warm-hearted help!

Hi, I am working on optimizing "PMP Mod 1.01" for AVC decoder, and I noticed following functions[1] in PMP Mod 1.01\libavcodec\h264idct.c are cpu consuming. The only optimization I can find now is to expand loop (e.g. expand "for(i=1;i<8;i++) {foo(i)}" to "foo(1);foo(2);...;...

I want to optimize "PMP Mod 1.01" for AVC decoder (it's only 8fps for 480*272 600kbps AVC now), and I know I can set two time counters (one for total run time, one for a target function's total run time) to try to catch the bottle neck function (eg. H264_decoder_frame). But I prefer to fin...

Any one knows?
