similar to: getting ready for alpha 3

So, release priorities. I have all of derf's proposed bitstream changes accounted for in the reference encoder, if not supported in the decoder. These are going to be released as alpha 3 to get the new bitstream changes out for wider testing while we work on spec and implementations of the extensions. The remaining issue is the broken buffering in splayer. I'll take care of that

Derf's from-scratch alternate implementation of the theora codec is now publicly available from our subversion repository. http://svn.xiph.org/experimental/derf/theora-exp/ This exciting new codebase promises superiour performance, and the encoder is capable of higher quality output than the current represenation, taking advantage of the bitstream extension we've added to the

Hi, A few questions: Is libtheora strictly backward compatible with VP3? Can I set it up to shove raw VP3 data through and trust it to decode the same way as On2's open source code did, loop filters and all? Also, is libtheora just supposed to be a C-based reference implementation? I was looking through the code and noticed a distinct lack of any kind of optimizations. Naive tree-based

Dan, In reviewing the code, derf came across the DCSearchPoints array in QuadCodeDisplayFragments(), encode.c:696. It looks like it specifies a search order for nearby coded fragments for prediction if there isn't a nearest neighbor. However, the upper search bound is defined as *0*, so the search loop (line 917) is never executed and it always falls back to the last coded fragment.

Monty, Derf and I were discussing some theora bitstream improvements. He was curious about the spare bits in the keyframe header. There's a keyframe type bit which is always DCT_KEY_FRAME aka '0' and two spare bits. You took out a lot of similar extra bits in the VP3 code. Do you remember anything about the motivation for leaving this one in? Given the constant, were there plans

Hi! I have the same situation, but some more information : 1) I have tried to change the last line to "APPEND root=/dev/sda1", it did not seem to make any difference 2) If I type ENTER at the prompt, syslinux loads the kernel (but with the same results mentioned above). So, clearly I have a problem with my extlinux.conf. Thanks Mau On Thu, Jan 16, 2014 at 10:33 AM, Mau Z

Hi, I have problems compiling R 2.2.0 under AIX 4.3 with GCC and xlf95 (FORTRAN) Compilers. here the error message I got: make[1]: Entering directory `/home/mau/sy/R-2.2.0/src/modules/X11' make[1]: `Makedeps' is up to date. make[1]: Leaving directory `/home/mau/sy/R-2.2.0/src/modules/X11' make[1]: Entering directory `/home/mau/sy/R-2.2.0/src/modules/X11' /usr/local/bin/gcc

Hi, I've been thinking about how a Theora encoder could be integrated into mencoder or transcode and I'm not sure whether I understand the A/V sync strategy of Theora/Vorbis correctly. When transcoding from some video format (ie MPEG2 or DivX), at least some images of the video stream will have time stamps, as well as the fragments of the audio stream. Or at least time stamps can be

Hello all. I've been playing around with theora since it first entered CVS, and I like what I'm seeing. Today I've been fixing xine's theoraplugin to understand theora_info.frame_{width,height} and theora_info.offset_{x,y}. I only got it working after some experimenting and basically copying the code from player_example. A few questions related to this: 1. What are the legal

Hi, I havent posted to this list before, so "hi" I have been experimenting with Theora and noticed it still has the same crash bug that VP3 did. Basically, if you begin compression, and compress a blank black frame more than about twice in a row you get a Div by 0 error. I traced the fault to being in the "RegulateQ" function, and is because YUVAnalyseFrame() returns 0 for

Thanks but I am still in the same spot : 1) I have created a partition (ext2 with GParted). 2) Now what ? I was thinking that I should install syslinux (the bootloader). All the examples say something like "syslinux --directory /boot/syslinux/ --install /dev/sdb1" but this does not make any seance, because the is no /boot on the system. I have tried it anyways, but the

Hi I understand you (mostly). 0) How do i "install the MBR code as well and to activate your partition." 1) "mount /dev/sda1 /mnt" -->> successfully completed. 2) "mkdir /mnt/extlinux" -->> successfully completed. 3) "extlinux --install /mnt/extlinux" -->> does not work. Funny, but it it seems that there is no such thing as

as per yesterday's discussion at #theora -- It has been suggested that we devise a method such that we will be able to add certain features to the bitstream (interlace, exotic color subsampling, clip length flag for download, etc), in such a way as to not obsolete streams encoded previously. Rillian's suggestion, which is pretty much standard practice, is to add a bitstream revision

Hi John, all, I still have at least 3 issues: 1) What are we trying to achieve with the "source-ID"? 8 [uint] Source ID (Unique amongst all OggPCM streams in the physical stream) Are we trying to separate the different channels that may be interleaved with each other inside the flat multi-channel sample stream? Interpretation 1: ----------------- So, would each channel be in a

Hi, How can we set the minimum addressable memory unit to be 32 bit ? As far as I know, getTargetData() provides all type sizes and alignments to compute address offsets assuming a MAU of 8 bits. But what if I have a MAU of 32 bits ? Currently I have 2 legal types in my BE, i16 and v2i16, and I could set TargetData in order to have v2i16 types with a size and alignment of 8 bits. Doing so, I

Hi! I was looking to download EXTLINUX in the following page : http://www.syslinux.org/wiki/index.php/Download But I do not see that it can be done. It is said that "The SYSLINUX download includes PXELINUX, ISOLINUX and MEMDISK as well." But, there is no word about EXTLINUX Please, advise Thanks Mau

Derf, It looks like your cleanup patch broke the encoder?

I'm pleased to announce the alpha 3 release of the theora reference implementation. http://theora.org/files/libtheora-1.0alpha3.tar.bz2 http://theora.org/files/libtheora-1.0alpha3.tar.gz http://theora.org/files/libtheora-1.0alpha3.zip The main differences over alpha 2: The encoded image has been flipped to match the sense used in VP3, with the origin at the lower left.
