Raphael, Some 15 years ago I implemented limited functionality Theora in our cameras FPGA (it took me 6 month of hard labor), and then gave up - it is a very crowded space and it is difficult to compete with more advanced codecs. And for our other work we anyway need almost raw image data, so we are using JPEG-based JP4 format (https://community.elphel.com/jp4) that we originally developed for

Hi Andrey, Thank you for your answer.Actually, NHW is very low-power so I think it could be geared toward any hardware.But actually I don't have hardware skills, so NHW is not a real hardware project for now maybe? I agree with you that it is extremely difficult (for me) to build a community around NHW, I'm certainly very bad/underskilled at it.Any help is welcome! Cheers, Raphael Le

Our discussion in the "Theora Camcorder" thread has been great, but I didn't see a direction evolve for action yet. So, I'd like to propose the creation of a community website that will be focused specifically on this kind of thing, partnered with the Xiph Foundation. I'm also more than happy to host said website, as I have more than ample server capacity for that. I just

Hello all, I'm trying to use the adimpro package to read RAW files (image).

I'm considering implementing the Theora format in the FPGA of the new camera. The previous model (Elphel 313 - http://www.elphel.com, https://sourceforge.net/projects/elphel) had smaller FPGA and was able to produce just motion JPEG utilizing 97% of the resources. The new (model 333) camera uses 3 times bigger FPGA (and also faster), it also has increased frame buffer and system memory.

Conrad, Small buglet with the 0.9.1 liboggz release (go dude!) http://thaumas.net/~giles/xiph/elphel/clips/elphel_00017.ogg causes a float exception in oggzinfo when it tries to calculate the bitrate. It fails to measure the duration and tries to divide by zero. :) There may well be something wrong with the file, although oggz-validate doesn't complain. Also, the configure script

In the discussion of having a freedom-friendly camcorder or other video device, we discussed the idea of using intra-only Theora video to make post-recording editing a much easier process, allowing things like frame-by-frame editing without the need to decode and reencode the video again, thus incurring loss. I was quite skeptical of the efficiency of intra-only Theora, and I had speculated that

Today I've got first video clips made by the camera and compressed "on the fly" - 1280x1024x30fps. Image quality is far from perfect - I don't have yet any way to preview images, and a single acquisition still requires a bunch of commands. So I'm really close to have a camera that will be able to serve the Ogg/Theora streams, now but will it be possible to play it on a PC? I

Hi, Is somewhere alghorithm description of encoder process implemented in libtheora? May be some drafts? May be frame dataflow throw encoder stages?

Here http://lists.xiph.org/pipermail/theora/2004-September/000619.html Andrey describe encoder structure, this like: "I see the following structure of the compressor implemented in the FPGA (Xilinx Spartan 3 1000K gates): 1. Data from the external frame buffer (FB) memory goes to the Bayer-to-YCbCr (4:2:0) converter in overlapping 20x20 tiles that produce 6 8x8 blocks (one macroblock) on the

Andrey Filippov reports at his sourceforge website that he is 50% of the way towards the implementation of ogg theora in a FPGA, and has a goal of reaching 100% (leaving out motion compensation) by Dec. 14, 2004. These are some of the tasks he has completed most recently: Added 8-point forward DCT following the algorithm suggested in Theora specs. 2004-10-31 22:17 Created 2-d IDCT according

Greetings, I am Iti Shree, sophomore year student pursuing Information and Technology.I was browsing through Xapian GSoC 2019 Ideas Page and found a really interesting project - "Matcher Optimisations" I have done quite a few projects in C++ and C source. Previous summer I worked for apertus Association in GSoC and my project was in C. Here is my github profile link:

Greetings, fellow R'ers. How can I get this frame in R: ID meas ID.1 meas.1 1 1.1 3 1.2 2 2.1 4 2.2 to look like this (stacking): ID meas 1 1.1 2 2.1 3 1.2 4 2.2 It's not really the reshape function (or is it?) because we can consider the additional columns, viz., ID.1 and meas.1, as independent of ID and meas so it is basically a stacking

Dear R-helpers, I have to read some large csv-files into R (30 - 100MB). Since reading with read.csv leads to "memory exhausted", I tried with scan(), skipping not needed columns by NULL-elements in "what". When these skipped elements are quoted strings with commata inside, R interprets each such quoted comma as element separator leading to wrong records in the rest of the
