OGG lossless?
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, Bostjan

opus lossless?
Hi All, It is possible to make Opus/CELT a lossless coder if I allow a sufficiently high bit rate? We considered using FLAC, but FLAC's latency is well beyond the acceptable range.

Lossless/lossy hybrid?
Monkey's Audio lossless compressor (currently win32 only, free but not open-source except decoder) author is thinking to implement a kind of audiophile-quality lossy compression which would filter "noise bits" that are hard to encode lossless but which are (or should be) inaudible and thus improve lossless compression (avg. 300-450kbps). I think that implementing something like this

WAV header (hey Mike)
So, I saw a form of wav header I didn;t know about today. It's not in my (admittedly aging) copy of the RIFF spec from M$, but it's pretty clear how to handle it (mostly in the context of OggEnc). Here's a dump with od -c: 0000000 R I F F 370 357 l 002 W A V E f m t 0000020 020 \0 \0 \0 001 \0 002 \0 D 254 \0 \0 020 261 002 \0 0000040 004 \0

Lossless Video Codec
Hi, has the subject of creating a lossless video codec been considered? I know Dirac is available, but it is a hybrid; saving a file and having to set a compression setting is not very intuitive for a novice. I suggest a lossless codec for the distant future, an idea of the codec's name is: FLAV. Free Lossless Agile Video. The goals of it would be: Provide lossless video, have a

Lossless compression
I was just somewhat curious as to what lossless compression is used... is it just huffman? Tony Arcieri --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/

Can't eagerly load a polymorphic association defined in an STI parent class?
If I define an association (in my case a polymorphic one) in an STI parent class, and try to eagerly load it in a subclass, I get the following error: ActiveRecord::ConfigurationError: Association name ''myassoc'' was not found; perhaps you misspelled it? If I redefine the same association again in the STI subclass, it works. Is this a bug or what? -- You received this message

Variable Bit Rate
Is FLAC a variable bit rate format when streamed?

ffmpeg2theora 0.25 synchronization issues when converting from .mov
Has anyone noticed this? I have a video made with Final Cut Pro, which I convert to .mov via Compressor. This .mov file plays back fine in Quicktime. But when I then use ffmpeg2theora to convert to ogv, the video seems to play back too fast compared to the audio (I'm using VLC 1.0.2, the latest I believe, to play back the ogv file, and I also have an app that uses the recently

SHN
I am interetsed to know views on how does best quality ogg compression compare with SHN or whether this is this really comparing apples with oranges because SHN does not compress that greatly? I am on a Music list that is doing a Tape Tree. I guess Grateful dead have made SHN the cult leader format. -- Raena Lea-Shannon --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg

theora encoder reordering, order of puting data from DCT 8x8 blocks to huffman compressor, and puting result of huffman compressor to buffer bitstream memory
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

Lossless audio codecs for video editing
Hi, this email is sent to flac-dev AT xiph DOT org, copied to matroska-devel AT lists DOT matroska DOT org, and David Bryant, the author of Wavpack4. We are about to implement the DV ( Digital Video ) video compression standard into matroska, to be able to offer an intelligent alternative to AVI for DV handling in editor tools. DV is using a high quality, high bitrate lossy video compression

Exact metadata reproduction
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

Why so many lossless formats?
Hi folks, I'm trying to get a handle on the many lossless audio formats from the perspective of a software developer. I love the FLAC format because it is open source and it performs very well. But there is also the MLP (Meridian Lossless Packing), AAC (Apple Lossless), and probably some Microsoft format(s) that compete in the same feature set. These formats all achieve

Lossless stream from MPD...
Any way to setup a lossless stream from MPD? I know MPD can encode FLAC, but I don't know if Icecast can handle it.

Bug with FLAC raw encoding
I found a bug with FLAC v0.6 raw encoding. It appears that the file pointer in the source file is not reset after seeking to the end for checking the size. I've attached a patch. I'm excited about FLAC!! I've been looking for a good GPL lossless RAW audio compressor for use with sound fonts. Sound font files contain 16 bit samples that are word aligned, so just treating it as raw

bitrtate peeling and lossless compression
I just read some of the discussion on the list about 'bitrate peeling' and remembered an interview of Monty that I have read recently. In it he says that Vorbis uses MCDTs <sp> and that these are theoretically reversable. And now, I learn that theoretically we can use bitrate peeling to make smaller files from larger ones, and that leads to my question. Could I theoretically

Coping music from tapes
OS: CentOS 5.0 x86. Hi, I have some old music tapes and a walkman, and want to move the music to mp3 format. So far I am thinking to use Audacity to record the music to wavs, and then do not know, somehow I will compress the wavs to mp3s as vbr 192 Kbps with something. Has anyone done this? What app did you use for recording the music from the tapes and what app did you use to make it mp3?
