Hello, attached is a gzipped patch file to the lib/mcomp.c source file of theora (as of AnonCVS current version) that implements MMX and extended-MMX optimizations in the most frequently used functions of the encoder (as shown by gprof). This is more a proof of concept than a real request for inclusion into the source tree. My personal intent was more to look deeper into the MMX instruction set

Whatever became of Ogg Theora? There seems to be still almost no news from Xiph or its developers regarding Ogg Theora. None at all since Mid-December, when the release of Alpha 2 was pushed back to a month ago... No news on plans for the second Alpha? No news of development "roadmaps"? No news on current developments or challenges that are stalling development? No CVS updates

Greetings, I don't know how common an issue this is as I haven't found much in the list archives that was helpful to me, so I'm hoping for some pointers. FYI, we have samba 2.3.3a-6 running on the 2.4.18-10 kernel. There seems to be an issue with smbfs mounts at times where connectivity may be lost (e.g. Win share becomes unavailable) causing local processes such as lsof or ps,

Hi, I'm developing ffdshow and ffvfw codecs for Windows. You can read more about them at http://cutka.szm.sk and http://sourceforge.net/projects/ffdshow. Stéphane Bérubé asked me recently if I could implement Theora support. I knew about first Theora release, downloaded its sources and tested it. I liked the results add decided to support it. I implemented encoding functionality into ffvfw,

As I understand it the current plan is to make it possible to losslessly transcode VP3 video to Theora video. In my experience, one of the "features" of VP3 is it drops frames in the event that there is little/no movement in a frame, or if "drop frames" is enabled, to drop frames if the data rate is getting too high. I understand that the way that VP3 does this in

some of you may find this helpful: I've uploaded a short (5 second) raw clip in yuv4mpeg format, associated audio, and batch files to exercise the encoder & decoder examples. In addition I've included the file as compressed (test.ogg), and a longer version as well to test playback sync. Notes: to use MPlayer with the -vo yuv4mpeg option, you need to get the latest release and compile

Hello everybody, I hope to finish this MIME types discussion with these conclusions - it's taken enough bandwidth on these lists :). So here's a generic MIME types scheme that we all seem to be able to agree on and all that is needed for the moment. --- 1) Ogg encapsulated files: Any data that is encapsulated in an Ogg container will us the MIME type: application/ogg (as already

I'm using pxelinux in an interesting way, to load DOS boot disk images from a win2k RIS (Remote installation Service) to do various functions. Soem of the disk images are used for flashing the BIOS on pcs, but a specific few are set aside for booting MSDOS with MS lanman so that ghost can be run to load images to/from the lan. I've got 6 different disk images setup and the all work

I haven't actually had many questions up to now. Despite the all-encompassing CP_INSTANCE monolith, things have been relatively easy going. Now we get into real grit: First off, CBitman looks like it has endianness issues; it's packing into host-order 32 bit arrays (the comments and symbol names seem to indicate that this was originally byte-based packing code that got upped to 32 bit.

What's the current status of VP3/Ogg integration? The CVS doesn't seem to be very active - and (maybe I'm not looking hard enough) I don't see any ogg-specific stuff here. I'm one of around 30 global techs for Indymedia, one of the last things we need for full adoption of free media formats is a free video format. We're working hard to promote Vorbis, many of the local

I don't know how to change a video quality on the fly - I want to provide a slider with a preview window, so user could see the result immediately in this window. I tried to send ICM_COMPRESS_FRAMES_INFO to encoder or calling ICSetState() - with no success however. Am I doing something wrong ? How can I set 'lDataRate', 'dwRate', 'dwScale' parameters ? I tried every

I found out about vp3 from the new winamp and coincidentally i also happen to be trying to find a suitable solution to broadband streaming. I have used flaskmpeg to create a 17mb .avi file from an 82mb Mpeg 1 file and it looks great it took about twenty minutes to encode. It runs for eight minutes and the audio is also fantastic using the lame encoder. However when I try to do the same in

Hi, There seem to be 2 sets of block coding patterns in the VP3x/Theora algorithm. Based on the comments in the code, the first pattern is used if encoder version < 6 and the second pattern is used in encoder version >= 6. None of the code to support the second pattern is ever called. Is there an encoder with a version >= 6? The code in question is

How does the Theora project differ from Nullsofts NSV project?

I there was a discussion on the vorbis list about Real Audio SureStream (tm) format. The basic idea was that they put multiple RA files with different compression levels. So when they have to switch the bit rate due to bandwidth changes, they choose from the streams they have. Since peeling is a long time away, it could be implemented with ogg vorbis multiplexing several times the same

hallo, is there any documentation available (or at least has any decision been made on this yet) what the system layer for theora will exactly look like? i guess it will be ogg, but afaik ogg itself is not very specific on how to pack different media format streams into one ogg stream, how to do a/v syncronization ... all the little details. on the other hand there is already such a
