Hello, I'm attaching IDCT MMX patch. I reused IDCT from theora-a3-MMXd.zip. It should work on 64bit X86 platform too. Here is most used functions when playing video with jet aircrafts (gripen) Ogg logical stream 310b2968 is Theora 720x480 29.97 fps video Encoded frame content is 720x480 with 0x0 offset I can play this video with like 200-300 frame drops on Athlon XP 1700+ CPU load (with

Hello, I would like to announce the semi-optimized oc_state_loop_filter_frag_rows It gains like 7% speedup. Unfortunately it has some issues: 1) wont compile on 64bit (I will fix it later hopefully) 2) is not yet fully optimized (instruction stalls) Here are the results. CPU: Athlon, speed 1466.91 MHz (estimated) Counted CPU_CLK_UNHALTED events (Cycles outside of halt state) with a unit mask

Hello, Here is my first speedup patch. Like 10-11%. No IDCT yet. Please feel free to comment my code or even better think about improvements. :) I belive my routines are not so bad, maybe one day they will be even more faster. What needs to be optimized is the loop filter fuction. I have no ideas now how to do it. It does not leave much space for parallel stuff, copying memory from lot of

Hi, I'm attempting to decode Theora videos on a PowerPC running a Linux 2.6.19 kernel. The version of GCC I'm cross-compiling from is 3.4.4. The software versions I'm running are: libogg-1.1.3 libpng-1.2.20 libtheora-1.0beta1 libvorbis-1.2.0 These are all the latest I was able to download. Here's a back trace I got while running "dump_video" under

/*Determines the number of blocks or coefficients to be skipped for a given token value. _token: The token value to skip. _extra_bits: The extra bits attached to this token. Return: A positive value indicates that number of coefficients are to be skipped in the current block. Otherwise, the negative of the return value indicates that number of blocks are to be ended. 0 will never be returned,

Hi all-- I tried building the ARM-optimized theora codec from the theorarm- merge-branch, and encountered the following compile and runtime problems before getting something to run. If there is another way to build it, it would be nice to know, but I got the sense that its current state in svn is incomplete. I'm using a gcc cross-compiler for ARM on an x86 Linux PC. After running

Hi, I am very new to Theora, having just started working through the code a few weeks ago. I am working on a requantization tool to reduce bit rates, hopefully on the fly, for some video conferencing work. As I was working through the encoding phase I noticed this line in encode.c: for(ti=_enc->dct_token_offs[pli][zzi];ti<ndct_tokens;ti++){ It's around line 804, but I am

Hi, I'm new to Theora and would like to propose several performance optimization using advanced instructions in x86 CPUs (SSE2-SSE4.2). There are several source files in \x86 and \x86_vc which developed using inline assembler. However this cause several maintenance problems: 1) Need to sync gcc & msvc versions 2) Only 32bit environment is supported 3) No support for newer than MMX

Hi, This patch adds Altivec-optimized implementations of oc_enc_frag_sad and oc_enc_frag_ssd. This patch is against the latest svn revision of theora-ptalarbvorm. Speeds up encode on a plant stop-motion clip on a 1 GHz PPC 7447 by ~3%, timewise. Time spent in oc_enc_frag_sad is reduced from 4.2% to 2.3% and oc_enc_frag_ssd from 1.2% to 1.0%, as reported by Shark. Currently this is only

Hi. I am trying to find calls of idct/fdct.c functions by tracing png2theora.c calls. But found only: analyze.c:oc_dct_cost2() Where and when idct/fdct/mmxidct/mmxfdct.c functions are used? Mentions of "dct" word: ==== pacify at optima-amd64:/usr/src/libtheora-1.2.0alpha1/lib$ grep dct *.c | cut -f1 -d":" | uniq -c ???? 19 analyze.c ???? 28 decode.c ???? 22 encode.c ????? 4

When using the IDCT routines, the C version [ lib/idct.c: oc_idct8x8_c(ogg_int16_t _y[64],int _last_zzi)] in libtheora 1.1.1, the decoded image is garbled. Is it functionally equivalent to the MMX optimized version [lib/x86/mmxidct.c: oc_idct8x8_mmx(ogg_int16_t _y[64],int _last_zzi)] ? I used some of the Theora video files from here: http://wiki.xiph.org/index.php/List_of_Theora_videos for

Hi, When I use FreeBSD-6.0 Release (also FreeBSD-5.4), I found IPSEC can't coexists with MAC. When the IpSec is setup, and we connects the TCP server with IPSEC and MAC support, the server innevitably crack. Because the m_pkthdr of some mbuf is mangled by unknown reasons. Following is my kernel configuration: options MAC options MAC_DEBUG options UFS_EXTATTR options

I would like to integrate the uploadify plugin with a standard rails form. However I can''t figure out how to add a new field and have it get submitted with the file upload. I added a name field into the form, but the valued does not get submitted. <% dialog_file_description = ''Photos'' allowed_extensions = [:jpg, :jpeg, :gif, :png] max_size = 20.megabyte

Hi, I''m programming a Ruby on Rails project where I am on the edit page of /boxes/1/edit and I''m trying to make an InPlaceEditor for the color property.

Hi Anne, I would suggest to change the linear model to lm(BloodPressure~Age), as this model makes more sense in biological means (you would assume that age influences pressure, not vice versa) and also obeys the statistical assumption of weak exogeneity, that age can be measured without error, at least compared to error-prone bp measures.
