Good day! I'm creating HDL IP CORE (for using in FPGA) for theora encoder (now only I-frames). I don't undestand one moment. Now i develop such stages: 1. From RBG(byer) to YCbCr converter 2. DCT processing (8x8 pixels blocks) 3. Quantizator of DCT coeff. 4. Zig-Zag of quantized DCT coeff. and now i have uresolved last stage of compression - how i must send 8x8 blocks to huffman

...own issue, after trying to run for the first time, it complained a missing dll (mfc42.dll). That was easy to solve and I got camstudio opening the recorder. The problem started where, when I click on record. It says: Error creating avi file! I tryed so many things but the problem I found was the compressors list in OPTION -> VIDEO OPTIONS does not show any compressor. I also add a registry entry but no change Plz, does anyone could give to me a hint on how to solve that. tks in advance. P.S. here the regedit fix REGEDIT4 [HKEY_CLASSES_ROOT\avifile\Compressors] [HKEY_CLASSES_ROOT\avifile\Comp...

Hi Guys, I was wondering what the idea behind the "Key Frame" settings are in the VP3 codec settings. As far as I could ascertain (from browsing through the source code) the VP3 codec ignores the lpbiPrev and lpPrev members of the ICCOMPRESS structure. My conclusion is thus that each frame passed to the codec is compressed individually and that the redundant information based upon

Hi, I searched the Internet to find an answers, but I didn't find anything useful, so I'm turning to you, maybe someone has the answer. I want to make a realtime broadcast from a Linux box. The source is the soundcard's line-in, and it sends the stream to an Icecast server. I would like to have realtime compressor/limiter functionalities on this Linux box, so the outgoing signal

Its been a while since I was discussing a SoundFont compressor based on FLAC. I've recently implemented the compressor using an application metadata block with the ID 'SFFL' that I registered, which contains my own header and a block of zlib (gzip) compressed SoundFont info. The audio chunk (a block of consecutive 16 bit signed samples separated by 46 zero samples) is then encoded with

Hi, Is there a way in which rsync's -z compression (zlib) utility can be benchmarked? I'm trying to compare the compression ratio between rsync and external compression tools like gzip and bzip2. Are there any advantages to using rsync's internal compression mechanism specified with the -z option compared to solely applying external compression i.e. bzip2 to the files and invoking

.... If you plan to stream in ogg vorbis, you can use Ices 2.x and accept PCM via standard input. This means you could run a sox effect or ecasound to get and compress the sound from the soundcard before sending it on to ices. Ecasound can make use of LADSPA plugins which opens you to a range of compressors, such as the SWH compressor plugins which I'm told are pretty good. If you want to do MP3 then I don't have any good ideas so far. Darkice doesn't allow either receiving from standard input or inserting processing (i.e. starting a subprocess which it sends audio to and receives aud...

Hi everyone, I need to trigger a Rails action after the autocompletion is completed (when the user has selected an option). From the scriptaculous doc, I figured out ''afterUpdateElement'' is the place to be but I wonder if/how and where I can hook my javascript code to this event in Rails code (I''d like to keep using the helper, if possible)? I tried passing many

http://code.google.com/p/snappy/ Google's methodology on this is to compress fast by taking advantage of 64-bit processing for volume, and stripping out secondary analysis for speed. I am using tinc on a mix of 32-bit and 64-bit routers: this may be useful for at least inter-x64 links (it will still work on 32-bit chips, just slower). -------------- next part -------------- An HTML

Hi! I'm just now preparing the first, still very experimental (way pre-1.0) release of a new archival tool, similar to (and based on) zip/unzip, with the difference that the enhanced zip tool can store x86-based decompressor code fragments in archives along with the compressed data, which the unzip tool runs in an isolated user-mode virtual machine in order to extract the data. The main

Hello, I noticed that kbps jumps quite high in -q 10 mode and is nearing lossless compressors. Would it be a difficult task to make OGG a lossless compressor at -q 10? I don't know much about lossy/lossless compression internal logic, so excuse me if my question is out of place. But this would be a really nice feature that would make OGG an "all in one" tool. Cheers, Bostja...

...mple Plugin API (see http://www.ladspa.org/). Basically, it was pointed out on the linux audio dev (LAD) mailing list that numerous programs were using plugin architectures and all were different. So they fleshed out a plugin API and the rest, as they say, is history. Right now, only things like compressors, expanders and limiters would probably be useful to insert into a stream, but if someone wrote an equaliser or a gate or something, that could well be useful too.

Hello, I'm not sure whether this message belongs to the "broadcast" side of Icecast, but.. I'm broadcasting a few radio stations but I always have level problems. Either the sound is too low, either it saturates. There's a very fine line between the two and the broadcasters are not always paying attention to the output level. Some radios are on Oddcast / XP, some on
