similar to: Getting only frame deltas?

hi all, i'm trying to code a tool to get some images from a ogg/theora file .... so basically i need to get a frame and convert to rgb ... and here is my question (sorry, i'm newbe here) ... how to convert a yuv_buffer to a rgb matrix ? i tryied diferent ways but my mistakes are bassically cause i don't understant how yuv_buffer structure works ... anybody can help? thanks a lot.

Hello all, When I'm doing something like: yuv_buffer yuv; theora_decode_YUVout(&td,&yuv); I'm guessing a bunch of stuff gets newed/malloced for yuv.y, yuv.u, and yuv.u. Who is responsible for deleting/freeing that stuff? Cheers, Kos.

Hi, I am using the densCols to draw a high volume scatter plot. Instead of using the default local density, I would like to take log of the local density and then map them to the colors. I could not figure out how to do that. For example: plot(x,y,col=densCols(x,y,"log")) ? Any help would be appreciated! Jiaxiu [[alternative HTML version deleted]]

This is a note to announce the availability of "Ogg Theorarm", an optimised ARM implementation of decoding libraries for the Theora video code, and Vorbis audio codec from xiph.org. Full details of this code release can be found at <http://www.wss.co.uk/pinknoise/theorarm>, but highlights include: * Full speed playback of a 320x240x25fps clip with a 48kHz stereo audio track on

Hi, I've eventually released the first version of my rendering library for Kate streams, and I've recently been hacking away at adding it to liboggplay. That was the missing "overlay" mode to the browser_plugin patch I sent a while ago. Now, I'm not too sure how to expose those overlays to liboggplay users: the obvious solution is to add a RGBA video type, and expose the

I'm currently doing research and initial development for an app that requires a rather odd usage of some kind of movie decoding. I'm trying to find a codec that I can trick into doing what I want, and so long as I can fix a problem or two, Theora is looking promising. What I want to do goes something like this: 1) Encode a whole bunch of two frame movies. For each movie, the

Hi everyone! I'm currently trying to use the theora decoder on PPC. Everything is working perfect now, but I have a problem: I need to skip the decoding of some frames (drop frames) when the device is not powerful enough to decode them all in real time (which in PPC is a frequent issue). Right now, I'm skipping the call to theora_decode_YUVout and the yuv to rgb procedure. That gives me

Hi, I heard that Theora will be used on OLPC. Is anyone working on optimization for OLPC? Regards, Chih-Chung Chang

Hi I need to a function that automatically fits a regression to data, using the stepAIC. I've ran the code manually and it works fine. However, when I run the function on the same data, the following error occurs: Problem in regimp(fullsim = simt, fullsim1 = simt1,..: Length of (weights) (variable 4) is 4271 != length of others (4278) I got the function to output the length of the dataset

Hi Ralph, thanks for your posting. Yes, the standard example player in the theora distribution could also do it when theora would not need so much time. I removed the frame dropping from the example because it's based on some audio stuff under Linux that isn't available on Windows. Currently I've no frame dropping handling build in because the first goal is a good raw performance of

Hello list, When I convert an yuv pixel into rgb using the recipies in http://www.fourcc.org/fccyvrgb.php I get an accurate color conversion but the contrast seems to be decreased. If i write, e.g., the pixel directly into an sdl yuv_overlay, I get a well-contrasted frame, however, if I convert the pixel to rgb and call SDL_MapRGB, I get a contrast-decreased frame. Thanks, Ribamar

Hello and sorry for necro posting xD this is the only thread I found about stalker. I really want this game to run. I've tried to run it under ubuntu but when I boot it ti makes xengine to crash... I've tried to follow the guide posted but i've got none of the packages from the line #yum install etc... how can I fix it? plz

hi all: i downloaded libtheora1.0.tar.gz from xiph.org, and when i compile it, such error message popped. i tried to run player_example.c under /libtheora_1.0/examples/. error message: ivysummer at ivysummer-desktop:~/??/libtheora-1.0/examples$ gcc -o player player_example.c /tmp/ccpyle3c.o: In function `buffer_data': player_example.c:(.text+0x15): undefined reference to

Hi , I just imported a large data set from notepad. I want to label the columns in R. I used 'import Dataset' to bring in my data set Now, I would like to label V1,V2,V3 etc??

Dear theora developer community, currently I'm working on a simple Theora player for Windows. But the code in the player_example.c seems not to have the performance of other implementations like the Direct Show filters by illuminate. In the example player, all important things are done in one thread: decoding the next vorbis or theora packet(s) and reading from the physical stream (+ split

Updated version of video preview covering frame writing every 3 keyframe and a xsl typo. Best regards :) kysucix -- Make things as simple as possible, but no simpler. - Albert Einstein

Hi. Here it is my patch to put a video preview of a theora stream in status.xsl. I just added a: <video-preview>1</video-preview> parameters in icecast.xml.in that control the previewing function. It encodes a png in $webroot/$mountname.tmp and then move it to $webroot/$mountname.png As for now it saves a frame every theora keyframe, which is probably too heavy for the server but

Hello guys, Firstly I would like to state that I am fairly new to Dovecot. I have played around with it in the past here and there but mainly with debian packages. I have compiled this version of Dovecot from source, so please go easy with me. Ok now down to my questions: I am having trouble getting Dovecot to 'ignore' the Trash folder when summing up the used quota for a user.

Hello, I am programmer working on a product which integrates Theora. I have a question regarding the memory use on some of the internals of Theora. Is this the right forum for this question, and if not, does anyone know where an appropriate place to ask is? Thanks Sam -------------- next part -------------- An HTML attachment was scrubbed...

I was wondering if the following is possible, or is planned for rsync. I backup a number of databases with rsync that work very well with the rsync algorithm. Ie, I am backing up a gigabyte+ database over a dial-up speed link and it doesn't take very long, so the daily differences in the files are obviously very small compared to it's total size. I am storing many copies of this database
